REAR PANEL CONTROLS (FIGURE 1)  
4. VIDEO 1 - VIDEO 4 (AUDIO & VIDEO)  
1. FM & AM ANTENNA  
Apart from the audio signal, these inputs will also accept a video signal  
which will be routed to the Monitor Out sockets (No. 7) for a television  
or video projector. The Video 1,2 and 3 inputs also have the option of a  
an S-Video connection (using the Mini-Din connector) or the standard  
Video Composite connection (using the yellow RCA socket).  
AM ANTENNA - An AM loop antenna is supplied with the T741 and is  
required for AM reception. Open the clip terminal lever and insert the  
wire from the antenna. Closing the lever will lock the wire in place  
(Fig. 5). Test various positions for the antenna, but always ensure the loop  
is placed vertically for best reception. Placing the antenna close to large  
metal items such as metal shelves or radiators may interfere with  
reception.  
The S-Video standard allows for higher quality video signal transfer when  
compared to the Video Composite standard. If your video components  
have an S-Video connector use dedicated S-Video leads to connect them  
to the T741 in the same way as described with the Video composite  
equivalents.  
NOTE  
When reception is not satisfactory using the supplied AM loop  
antenna alone, connection of an external antenna is recommended.  
Do not connect anything other than a loop antenna to the AM  
ANTENNA terminal. Do not remove the AM loop antenna. The  
antenna cable to the loop antenna must not exceed 3 meters.  
A video signal fed to an S-Video input socket will be available on both  
the S-Video Monitor Out and Video composite Monitor Out.  
VIDEO 1 & VIDEO 2 - Inputs for the audio playback and video signal  
from a video device such as a stereo TV, DVD player, satellite cable TV  
receiver or a Laser Disc. Using twin RCA-to-RCA leads, connect to the left  
and right ‘Audio Out’ of the video device to these inputs. Using a single  
RCA-to-RCA lead (Video Composite) or S-Video lead, also connect the  
video output of the video device; refer also to the description of S-Video  
and Video Composite above in this section. VIDEO 1 & VIDEO 2 can be  
used for video playback only. Use VIDEO 3 or VIDEO 4 if you want to  
connect a VCR for recording and playback through the T741.  
FM ANTENNA - A ribbon wire FM antenna is included and should be  
connected to the FM connector at the rear of the unit (Fig. 4) using the  
‘balun’ adapter supplied. The ribbon aerial should be mounted on a  
vertical surface and placed so that it forms a ‘T’.  
Experiment with placement of the antenna to find the position that gives  
the best signal strength and lowest background noise. An inadequate FM  
signal normally results in high levels of hiss, especially in stereo, and  
interference from external electrical sources. In areas of poor FM  
reception, the tuner sections performance can be improved by using an  
externally mounted FM antenna. A qualified aerial installer will be able to  
advise and fit a recommended aerial for your reception conditions.  
The optical Digital Input 1 (No. 5) is linked to the Video 1 input. Select  
Video 1 to hear a source connected to Digital Input 1.  
2. TAPE 1 & CD INPUT  
The coaxial Digital Input 2 (No. 5) is linked to the Video 2 input. Select  
Video 2 to hear a source connected to Digital Input 2.  
TAPE 1 - Connections for analogue recording and playback to an audio  
tape recorder of any type, such as a cassette, reel-reel, DAT, MD or DCC.

Output’ of the tape machine to the TAPE 1 IN connectors for playback.  
Connect the left and right ‘Audio Input’ of the tape machine to the TAPE  
1 OUT connectors for recording.  
VIDEO 3 & VIDEO 4 - Connections for the audio recording and playback  
to a VCR or other video recorder. Using twin RCA-to-RCA leads, connect  
to the left and right ‘Audio Out’ of the VCR to the VIDEO 3 or VIDEO 4  
IN connectors for playback. Connect the left and right ‘Audio In’ of the  
VCR to the VIDEO 3 or VIDEO 4 OUT connectors for recording. Using a  
single RCA-to-RCA (Video Composite) lead or S-Video lead, also connect  
the video output of the VCR to Video In for Video playback. Connect the  
Video Input of the VCR to Video Out of the NAD T741 receiver for  
recording of video signals. Refer also to the description of S-Video and  
Video Composite above in this section.  
CD INPUT - Input for CD player (analogue audio signal) or other line-level  
signal source. Use a twin RCA-to-RCA lead to connect the CD players left  
and right ‘Audio Outputs’ to this input.  
GB  
3. 5.1 CHANNEL INPUTS  
Inputs for the multi-channel audio signals from an external decoder, such  
as an MPEG decoder or a DVD player with integrated decoder. Use two  
twin RCA-to-RCA lead to connect the decoders front left and right  
“Audio Outputs” to the Front left and right inputs, and the decoders  
Surround left and right outputs to the Surround left and right inputs. Use  
a third twin RCA-to-RCA lead to connect the decoders subwoofer  
output to the Subwoofer input and the decoders Center channel output  
to the Center channel input. Make sure you to follow color coding of the  
plugs to ensure that both Center and Subwoofer are connected correctly,  
for instance, use the red plugs at either end to connect the center  
channel and the white plugs for the subwoofer channel.  
The coaxial Digital Input 3 (No. 5) is linked to the Video 3 input. Select  
Video 3 to hear a source connected to Digital Input 3.  
5. DIGITAL AUDIO INPUTS  
The T741 has three digital audio inputs to allow for connection of DVD,  
CD, Satellite receiver or other digital sources:  
Digital Audio Input 1 allows for connection of a digital source with an  
Optical output. Use a cable terminated with a TOS Link connector. Digital  
input 1 is linked to the Video 1 input.  
Digital Audio Inputs 2 & 3 allow for connection of a digital source with a  
Coaxial digital output. Use a cable with the right impedance, specifically  
designed for the transfer of digital signals. These digital inputs are linked  
respectively to VIDEO INPUT 2 and VIDEO INPUT 3.

6. AUDIO PRE-OUTS / SUBWOOFER OUT  
NOTE  
This unit is designed to produce optimum sound quality when  
AUDIO PRE-OUTS - The NAD T741 receiver has five power amplifiers  
built-in to power all the speakers connected to it (Left, Right, Center, Left  
Surround, Right Surround). It is also possible to use the T741 as a pre-  
amplifier to drive external power amplifiers. This way, you use all the  
control functions the T741 provides, such as input select, surround  
mode, volume, tone controls, etc., but the external power amplifier  
actually powers the speaker connected to it instead of the T741s  
integrated power amplifier for that channel.  
speakers with impedance within the set’s ranges are connected.  
Please check the following information and choose speakers with the  
correct impedance for the connections.  
FRONT SPEAKERS A: 8 ohms min. per speaker;  
CENTER SPEAKER B: 8 ohms min.  
SURROUND SPEAKERS: 8 ohms min. per speaker  
Connect the RCA-to-RCA leads from the Front left and Right, Center,  
and/or Surround Left and Right Audio pre-out connectors to the external  
amplifiers. Connect speakers to the external amplifiers.  
CENTER SPEAKER - The terminal marked ‘C’ connects to the center  
loudspeaker that is used when the T741 is operated in Dolby* Digital,  
DTS, Dolby Pro Logic, EARS surround sound mode or with the 5.1 Ch.  
input selected.  
NOTES  
Never connect the T741’s speaker outputs and the speaker outputs  
of an external amplifier to the same speakers. When headphones are  
inserted the signals from all audio pre-out outputs will be muted.  
Before making any connections, check that the T741 and the power  
amplifiers it will be connected to are switched off. With volume  
turned down to a low level, switch power on only after all  
connections have been made.  
Connect the center speaker in the same way as described with front  
speakers above.  
SURROUND SPEAKERS - This connects the Surround loudspeakers that  
are used when the T741 is operated in Dolby Digital, DTS, Dolby Pro  
Logic, EARS Surround sound modes or with the 5.1 Ch. input selected.  
Connect the surround speakers in the same way as described with  
FRONT SPEAKERS above; connect the left surround speaker to the set of  
terminals marked ‘SLand the right surround speaker to the terminals  
marked ‘SR’.  
SUBWOOFER OUT - Unlike for the full range five channels as described  
above, there is no power amplifier built-in for an additional subwoofer.  
The Subwoofer pre-out allows for connection to a sub-bass speaker  
system with its own external or integrated power amplifier (“active”  
subwoofers).  
NOTE  
The Center and/or Surround speakers must be selected as Large or  
Small in the Set-up menu “SPK SET” when speakers are connected to  
these outputs.  
7. MONITOR OUT  
Composite Video and S-Video outputs for connecting a TV or Video  
Monitor to view video sources connected to VIDEO 1 to VIDEO 5. Using  
a Video RCA-to-RCA lead, connect the “Video Line In” on the TV or  
monitor to the MONITOR OUT.  
9. SOFT CLIPPING  
When any amplifier is driven beyond its power output capabilities, a  
hard, distorted sound can be heard on very loud sounds. This is caused  
by the amplifier cutting off or ‘hard clipping’ the peaks of sound that it  
was not designed to reproduce. The NAD Soft Clipping circuit gently  
limits the output of the system to minimize audible distortion if the  
amplifier is overdriven.  
Note that an S-Video signal will also be available as a Video Composite  
signal on Monitor out, if the corresponding source is selected. The  
composite video input signals (No. 4; yellow sockets) will also be available  
as S-Video signal on the Monitor Out socket. If you use both S-Video and  
Video composite sources, you will only need to connect the S-Video  
Monitor Out to the television or projector.  
GB  
If your listening involves moderate power levels you may leave the Soft  
Clipping switch off. If you are likely to play at high levels that exceed the  
amplifiers power capability, then switch Soft Clipping on.  
8. SPEAKERS: FRONT, CENTER & SURROUND SPEAKERS  
FRONT SPEAKERS - Connect the right speaker to the terminals marked  
‘FR’ ensuring that the red terminal is connected to the ‘+’ terminal on  
your loudspeaker and the black terminal is connected to the  
loudspeakers -’ terminal. Connect the terminals marked “FL” to the left  
speaker in the same way.  
Always use heavy duty (16 gauge; 1.5mm or thicker) stranded wire to  
connect loudspeakers to your T741. Unscrew the speaker terminals  
plastic bushing. Insert the bare cable end into the hole of the terminal and  
then secure the cable by tightening down the terminals bushing (Fig. 6).  
To avoid any danger of bare metal from the speaker cables touching the  
back panel or another connector, ensure that there is only 1/2” (1.27cm)  
of bare cable and no loose strands of speaker wire.

FRONT PANEL CONTROLS (FIGURE 2)  
10. NAD-LINK IN OUT  
The NAD-Link connector is used to pass commands from other units fitted  
with NAD-Link connectors. This allows centralized control of a complete  
system, and also allows some of the basic functions of other NAD  
components (such as a CD player) also equipped with NAD-Link to be  
controlled with the receivers remote control. To function with such other  
units, connect the T741s NAD-Link Out to the NAD-Link In on the other  
unit. NAD-Link connectors can be daisy-chained, IN to OUT, so that a whole  
system can be controlled from the remote control facilities of one unit.  
1. POWER  
Press the POWER button to switch the receiver to STANDBY mode. Press  
any input selector button on the front panel or the POWER button (No. 1)  
on the Remote Control to switch the receiver fully on. The display will  
light up indicating which input was selected; the Stand-by indicator will  
extinguish. Pressing the POWER switch again will turn the unit OFF  
completely. The NAD T741 receiver uses a memory back-up system to  
store surround sound trim settings and Preset station information for the  
tuner section. This information is retained for several weeks, even the  
unit is switched off completely or unplugged.  
NOTES  
It is advisable not to connect NAD-Link if these units that have their  
own built-in remote control command receiver and are positioned  
together, in direct view from the remote control handset. If you are  
unsure, try operating the products without NAD-Link first; If the unit  
responds to the remote control command, it will not be necessary to  
connect NAD-Link.  
REMOTE CONTROL  
Power button - Press this button to switch the unit from operating to the  
Stand-by mode and vice versa. Press this button again to switch to unit on  
from Stand-by; the last selected source will be indicated in the display.  
Never loop the last unit back to the first NAD unit in the NAD-Link  
chain.  
NOTE  
Stand-by mode is indicated by the Stand-by indicator (No. 2) just over  
the green Power button on the front panel (No. 1).  
Unplug all units from the mains before connecting or disconnecting  
NAD-Link.  
In Stand-by mode the T741 uses very little power. However, it is  
recommended that you switch the unit totally off if it is not going to be  
used for more than a couple of days. Switch off completely by pressing  
the Power button on the front panel (No. 1), all lights will extinguish.  
11. AC POWER CORD  
After you have completed all connections to the amplifier, plug the AC  
line cord into a “live” wall socket.  
12. 12 VOLT TRIGGER OUT  
2. STAND-BY INDICATOR  
The 12V trigger output allows to remotely switch on or off ancillary  
equipment such as a CD player, power amplifier, etc. which are also  
equipped with a 12V trigger input. This can also be an AC outlet power  
strip equipped with a 12V trigger input. The 12V trigger output is  
activated whenever the T741 is switched to normal operational mode  
from Stand-by or Off.  
This green LED will light up when the receiver is switched On, but in  
Stand-by mode. Refer to section 1 in this chapter for more information.  
3. DISPLAY  
The T741s FM tuner supports RDS PS and RDS RT. With stations carrying  
RDS information, “RDS” will light up in the display panel, and the  
stations RDS name is automatically displayed (RDS PS).  
For switching Stand-by/Power On of the external component, connect  
the 12V trigger output of the T741 to the remote components DC input  
jack. The plug required is a standard 3.5mm Mini-Jack plug (“mono”):  
The tip is the live or + connection, the shaft of the jack is the 12V trigger  
- or ground connection.  
Some radio stations, which support RDS, also transmit additional  
information, known as Radio Text (RDS RT). To view this information, use  
the Display button. With stations carrying RDS information, the DISPLAY  
button scrolls between three different display modes, each successive  
push of the button engages the next one of the three modes:  
GB  
NOTES  
Check the specifications of the trigger input terminal on the other  
component to ensure it is compatible with the T741’s 12V trigger  
output.  
a) In the default mode, the stations RDS name is displayed, Program  
Service (PS; normally the stations calling letters, BBC R3, for instance).  
b) From the default mode, press the button once to view Radio Text (RT).  
This can be additional information such as the presenters or  
programs name; what song is playing, etc. This text scrolls  
continuously over the 8 alphanumeric display segments. It takes a  
few seconds for the tuner to gather the RT information, so  
immediately after tuning to a station and selecting to view RT the  
display will indicate “NO TEXT” and default to the station name. If no  
RT information is available, the display will also show “NO TEXT” for  
three seconds before reverting to the default mode.  
The T741’s 12V trigger output voltage is 12V DC. The total maximum  
current must not exceed 200mA. Typically, NAD 12V input triggers  
draw less then 10mA of current.  
NAD components equipped with 12V input triggers are fully  
compatible with the T741’s 12V trigger output.  
Before making any connections to any 12V trigger input or output,  
make sure all components are disconnected from the AC mains.  
Failure to observe the above may result in damage to the T741 or any  
ancillary components attached to it. If in doubt over the connections,  
installation and operation of the 12V trigger output consult your NAD  
dealer.  
c) Press the button from the display RT mode to display the station  
frequency. Press again to return to the default mode (a).  
When the DISPLAY button is pressed when tuned to a non-RDS station  
the display will show “NO NAME” for three seconds before reverting to  
the default display.

4. FM/AM  
8. DOWN / UP  
AND  
The FM/AM button switches the tuner section from the AM band to the  
FM band and vice-versa. The Display Panel shows the frequency of the  
tuned station and which band is selected. The FM tuning is in 0.05 MHz  
increments, AM tuning is in 9 kHz or 10kHz increments, depending on  
the version (9 kHz for the 230V version or 10 kHz for the 120V version).  
To change the AM increment tuning steps, press the FM/AM and CD  
buttons at the same time.  
The function of these buttons depends on the tuning mode selected with  
the Preset/Tune button (No. 7). The Preset/Tune button toggles between  
the two operation modes:  
a) Preset mode (indicated in the display area): Press the  
(down)  
button to scroll to a lower number Preset; press the  
(up) button  
to scroll to a higher Preset number. This is a “wrap-around” function,  
so that going from the highest number Preset, the tuner will go to  
the lowest Preset number or vice-versa when tuning either up or  
down.  
5. FM MUTE / MODE  
This button combines two functions; it switches the tuner from FM  
Stereo to Mono mode and disengages the muting circuitry at the same  
time. The muting circuit will mute the tuner in between radio stations  
when searching or tuning. This way the tuning noise is avoided.  
Very weak radio station signals however may be suppressed by the  
muting circuit. if such a very weak station is in stereo it will have a high  
level of background hiss. Switching to Mono and disengaging the  
muting circuit by depressing the FM MUTE/MODE button will allow the  
station to be heard and will cancel most or all of this background noise.  
b) Tune mode: Press the  
(down) or  
(up) button for more  
than 1/2 second to engage automatic tuning respectively up or down  
the frequency band. The tuner will search automatically for the first  
reasonably strong radio station, where it will stop. Press the Down/Up  
button again for 1/2 second to start searching again.  
NOTE  
Automatic tuning is available on both FM and AM.  
By briefly tapping the  
(down) or  
(up) buttons you can engage  
In normal operation the mute circuit is engaged, the display indicates  
“FM MUTE”. Press the FM Mute/Mode button to disengage the muting  
circuit and switch from stereo to mono reception. “FM MUTE” will  
extinguish in the display. Also, “FM STEREO” will extinguish if a stereo  
broadcast was received. Press the FM Mute/Mode switch again to return  
to Auto Stereo FM operation.  
manual tuning respectively down or up the frequency band for precise  
tuning to a specific frequency. With each successive tap of the keys, the  
tuner will take 0.05 MHz steps on FM so you can accurately tune into the  
desired frequency.  
This tuning mode can also be useful when trying to receive a radio  
station which is too weak for the auto search mode. When tuned  
In combination with the MEMORY button (No. 6) and DOWN/UP buttons  
(No. 8) a preset number can be emptied. (Refer to the separate chapter  
“Storing and Recalling Presets” for more information.)  
accurately to a station, “  
TUNED  
” will light up in the display.  
Very weak radio station signals however may be suppressed by the  
muting circuit. If such a very weak station is in stereo it will have a high  
level of background hiss. Switching to Mono and disengaging the  
muting circuit by depressing the FM MUTE/MODE button (No. 5) will  
allow the station to be heard and will cancel most or all of this  
background noise.  
6. MEMORY  
The Memory button is used to store stations into the Preset Memory (1-  
30 Presets on FM, 1-10 Presets on AM), used in conjunction with the  
Down/Up (No. 8) buttons on the front panel. In combination with the FM  
MUTE/MODE button (No. 5) and DOWN/UP buttons (No. 8) a preset  
number can be emptied. When Memory is active, the Preset number  
flashes and the red “MEMORY” indicator is shown in the Display Panel.  
If no other button is pressed within 10 seconds “MEMORY” will stop  
flashing and the receiver will default to its previous state.  
Refer to the separate chapter “Storing and Recalling Presets” for more  
information.  
9. VFL DISPLAY

Vacuum Fluorescent Display. The display area will show all vital  
information when the unit is operational.  
Refer to the separate chapter “Storing and recalling Presets” for more  
information.  
10. VOLUME & SET UP  
7. PRESET / TUNE  
In the default function, this control acts as a Volume control, adjusting  
the overall loudness of the signals being fed to the loudspeakers and  
headphones. Unlike conventional controls, the T741s volume control  
doesn’t have a start or end position. Volume can also be adjusted from  
the remote control handset using the Master Volume Up or Down  
buttons. The Volume control does not affect recordings made using the  
Tape, Video 3 and Video 4 outputs but will affect the signal going to the  
Pre-amp output (Audio Pre Out). The volume level is indicated in the  
display panel when it is being adjusted. After three seconds the display  
defaults to its previous status. Volume setting can range from  
to +18dB.  
The Preset/Tune button toggles between the Preset and Tune mode.  
When Preset mode is selected, “PRESET” lights up in the display area.  
Up to 40 Presets, either AM (10 Presets) or FM (30 Presets), can be stored.

11. HEADPHONE SOCKET & VIDEO 5 INPUT  
HEADPHONE SOCKET - A 1/4” stereo jack socket is supplied for  
headphone listening and will work with conventional headphones of any  
impedance. The volume and tone controls are operative for headphone  
listening. Use a suitable adapter to connect headphones with other types  
of connectors such as 3.5mm stereo ‘personal stereo’ jack plugs.  
Inserting a headphone will automatically turn off all speakers and signals  
from the Audio Pre-Out sockets and switches the T741 to the stereo  
mode. Surround sound modes are not available when headphones are  
inserted in the headphone socket.  
VIDEO OUTPUT - The video signal available on the S-Video and Video  
Composite outputs is dependent on the selected video input (VIDEO-1,  
VIDEO-2, VIDEO-3, VIDEO-4, VIDEO-5). However, when one of the  
audio-only sources is selected (FM, AM, CD, Tape Monitor or Ext. 5.1) the  
last selected video signal from one of the video inputs will be present on  
these outputs. This way you can watch a DVD player or video whilst  
listening to the CD player.  
The sound from the EXT. 5.1 CH input is not available on the headphones  
socket.  
NOTES  
In the VFL display “Speaker settings”, be sure to have selected and  
adjusted a preset with “MAIN SPEAKERS” set to “LARGE”. If set to  
“SMALL”, bass response will be limited.

DVD player connected to VIDEO 1 as the active input. “VIDEO-1” is  
shown in the Display Panel when selected.  
The Tape Monitor function does not override the current input selection.  
For example, if the CD is the active input when Tape Monitor is selected,  
the CD signal will continue to be selected and is sent to the Tape Out,  
Video 3 and Video 4 Out sockets. But it is the sound from recorder  
connected to Tape that will be heard on the loudspeakers when the TAPE  
MONITOR function is selected. When Tape Monitor is selected, “TAPE  
MONITOR” will remain lit until Tape Monitor is disengaged again.  
The Digital Input 1 is linked to the Video 1 input (marked Digital In 1 on  
back panel; No. 6). Digital Input 1 allows for connection of a digital  
source with an Optical (Toslink) digital output. Whenever the  
corresponding digital input is activated, Digital Input 1 will also be  
selected; in the display the “DIGITAL 1” indicator will start to blink. If a  
digital audio signal is detected, the “DIGITAL 1” indicator will stop  
blinking and remain lit. If no digital audio signal is detected, “DIGITAL 1”  
indicator will cease blinking and extinguish.

STORING AND RECALLING PRESETS  
TO STORE A PRESET  
DELETING A STORED PRESET  
You can empty a Preset by deleting the stored information:  
Tune to the radio station you wish to enter into a Preset (refer to  
chapter “Front Panel Controls”; section 8). If the station is  
transmitting RDS information, the RDS indicator will light up and  
station initials will be shown in the Display Panel. If a non-RDS station  
is found, then just the frequency will be shown.  
Press MEMORY button (No. 6).  
Press DOWN/UP buttons (No. 8) to select the preset number to be  
deleted.  
Press the FM MUTE/MODE button (No. 5). The Preset will then be  
deleted and ‘—’ appears as the Preset number.  
To store that station as a Preset, press MEMORY (No. 6). “MEMORY”  
and the preset section in the display panel will start to flash. If no  
other button is pressed within 10 seconds, “MEMORY” will stop to  
flash and the receiver will default to its previous state.  
You can also store a new station into a used Preset, by simply going  
through the Preset storing process and placing a new station over the  
existing one.  
Press either the  
(down) or  
(up) button to select which  
Preset number you wish to assign to the station (from 1 to 30 on FM  
and 1 to 10 on AM), shown as a flashing number in the Display Panel,  
and then press MEMORY (No. 6) again. The Memory light in the  
Display Panel will go out and the station is now stored in your NAD  
T741s memory.  
REMOTE CONTROL AVR-1 (FIGURE 3.)  
The T741 is supplied with the NAD AVR-1 Remote Control. Apart from  
all the primary operating functions, the AVR-1 Remote Control handset  
also gives access to functions not available on the front panel of the  
T741. It also has additional controls to remotely operate NAD T550, L55,  
T531 and T571 DVD Players. The function of the buttons will change  
between the T741 Receiver and the NAD DVD Player depending on the  
position of the RCVR/DVD switch (See 25 below). Shared buttons  
(buttons that function with the switch in either position) have the  
receiver function printed on the button itself, with the secondary DVD  
function printed on the body of the remote handset  
To exit the Memory mode without storing a station, leave all the tuner  
controls untouched; the Memory mode will automatically cancel itself  
after 10 seconds. The Memory Presets have a memory back-up, so they  
will remain stored for several weeks even if the Receiver is switched off or  
unplugged from the mains supply.  
NOTE  
You can enter a new station into an unused Preset or over-write an  
existing programmed Memory Preset. By doing this you will replace  
the radio station previously held on that Preset number.  
Alkaline batteries are recommended for maximum operating life. Two  
AAA (R 03) batteries should be fitted in the battery compartment at the  
rear of the Remote Control handset. When replacing batteries, check

both the DVD player and DVD Video discs. Refer to the NAD DVD player  
Owners Manual for more detailed information on this function.  
NOTE  
10. MUTE / ENTER  
Although we usually prefer to reproduce a source’s full dynamic  
range (the difference between very loud and very soft sounds), it may  
occasionally be desirable to reduce the dynamic range. For example,  
when playing a movie late at night, loud explosions might wake  
sleeping family members. Simply turning the volume control down  
would probably make a whisper in the next scene inaudible. The  
DYN. R button solves this dilemma by progressively lowering the  
volume of loud peaks while increasing the level of softer sounds.  
Press the MUTE button to temporarily switch off the sound to the  
speakers and headphones. Mute mode is indicated by “MUTING”  
flashing in red in the display area. Press MUTE again to restore sound.  
Mute does not affect recordings made using the Tape out-puts but will  
affect the signal going to the Audio Pre-outs and headphones.  
GB  
NOTE  
When the unit is in mute mode, any adjustment of the VOLUME  
CONTROL on the front panel (No.10) or Remote Control (No. 9) will  
release the muting, i.e. the original volume level will be resumed.  
7. TEST / TITLE  
Pressing the TEST button, engages the Test signal generator to allow for  
adjustment of all speaker levels, so that each channel can be adjusted for  
equal loudness at your listening position. The test signal scrolls  
automatically with 2 second intervals from Front Left, Center, Front Right,  
Rear Right, Rear Left, to subwoofer in continuous cycles. If an adjustment  
in setting is made for one of the speakers, scrolling will stop until  
2 seconds after the adjustment was made. The display panel shows  
which speaker is being fed with the test signal. Use the VOLUME +/-  
buttons to respectively increase or decrease the level for the current  
speaker. Press the TEST button again to leave or cancel the Test mode,  
any changes will be memorized automatically.  
11. TUNE UP / TUNE DOWN AND ARROW

SETTING UP THE SURROUND SYSTEM  
In DVD mode this buttons function is determined by the individual DVD  
disc title being played. Refer to the NAD DVD Player Owners Manual for  
more detailed information on this function.  
To obtain the best results in any of the Surround Modes it is important  
that the T741 is carefully set up. The Dolby Surround system requires  
that you specify the parameters of your speaker setup so it can properly  
direct the decoded surround sound signal in the correct proportion to  
create the most accurate theatrical effect. Dolby also allows for the  
redirection of bass frequencies to the most appropriate speaker(s). This  
is also known as “bass management”.

Now rotate the VOLUME/SETUP knob until REAR LAR (current setting for  
the SURROUND speakers) appears in the display window. Press the SET  
UP button again to change the size. Each press of the SET UP button will  
change the setting for that speaker:  
Many film soundtracks rely heavily on very low frequency sound effects  
which are difficult for normal or smaller hi-fi speakers to reproduce. To  
faithfully reproduce these low frequencies you can use a specially  
designed low frequency loudspeaker with its own built-in amplifier  
(“active subwoofer”). Because it is difficult to hear which direction very  
low frequencies are coming from, you only normally need one sub-  
woofer and this can be placed virtually anywhere in the room. The  
Subwoofer output of the T741 is designed specifically to drive a  
subwoofer system.  
REAR (Surround Speakers) can be set to LAR, SMA or OFF.  
Now rotate the VOLUME/SETUP knob until SUB ON (current setting for  
the Subwoofer) appears in the display window. Press the SET UP button  
again to change the setting. Each press of the SET UP button will change  
the setting for that speaker:  
SUB (subwoofer) can be set to ON, OFF.  
Dolby Digital uses a dedicated Low Frequency Effects (LFE) channel. If a  
subwoofer has been selected, the LFE channel will be fed to the sub-  
woofer output. If no subwoofer is selected the LFE channel is redirected  
to the front left and right speakers.  
Now rotate the VOLUME/SETUP knob until EXIT appears in the display  
window. Press the SET UP button again to exit SPEAKER SETTING MENU.  
Press the SET UP button again to exit the SET UP MENU. Your speaker  
settings are now complete. If in the future you add or change speakers,  
this setup procedure should be repeated.  
CHANNEL DELAYS  
For the best surround sound performance it is important that sound from  
all speakers reach the listeners ears at the same time. Because the  
surround/ rear speakers are usually closer to the listener than the front  
speakers, there is tendency for the ear to localize sounds to the rear,  
because the ear takes most notice of the sounds that arrive at the head  
first. Similarly, the center speaker is often closer to the listener than the  
front left and right speakers. To compensate for this, the T741 can  
slightly delay the audio sent to the center and rear (closer) speakers. In  
this way, when playing Dolby Digital or Dolby Pro logic soundtracks, the  
sound from all speakers arrives uniformly at the listening position as  
intended by the films producer.  
TIPS ON WHICH SPEAKER SETTINGS TO USE  
The four modes available to the T741s setup are: LARGE or SMALL and  
ON or OFF.  
The LARGE mode is used when the speaker is full range and capable of  
reproducing the entire audible frequency spectrum 20Hz to 20kHz. The  
SMALL mode is used when the speaker is not capable of reproducing the  
deepest bass portion of the audio frequency 20Hz to 100Hz.  
The ON mode is used when the speaker is active and receives the audio  
information intended. The OFF mode is used when the speaker is  
inactive. Audio signals intended for speakers set to the OFF position are  
redirected to the main speakers.  
Each millisecond corresponds approximately with 1 foot or 30.5  
centimeters.  
NOTE  
Using a separate center channel speaker will allow the dialogue to cut  
through even the biggest sound effects and musical scores. Having the  
sound spread across three front speakers also stabilizes the stereo image,  
making the usable listening area much bigger. For best results, you  
should consider using a center speaker. Ideally it should be the same type  
as the left and right speakers.  
The channel delay option is not available in DTS surround mode.  
TO ADJUST DELAY SETTINGS  
When Front Panel Display shows DELAY, pressing the SET UP button on  
front panel again (second press) will enter the DELAY SETTING menu.  
Rotate VOLUME/SETUP knob to cycle between CENT REAR EXIT.

Installing surround speakers will greatly enhance the surround experience  
as these add considerably to the overall “ambience”.  
First stop at CEN 0mS (current delay setting for Center Speaker). Press  
the SET UP button again to change the delay setting. Rotate the  
VOLUME/SETUP knob to change center delay adjustment in 1mS  
increments from 0mS to 5mS. Press SET UP button again to exit Center  
delay adjustment.  
Dolby Pro Logic encoded material is deliberately limited in dynamic range  
and frequency bandwidth for the surround channel and thus only  
requires speakers of far lesser specification compared to the front  
channels. Dolby Digital however is a full range system, with two  
independent surround channels and with dynamics equal to that of the  
front channels. For this reason it is advisable to choose loudspeakers  
which are similar in power handling and performance capability to those  
of the front channels. For best results, the Surround loudspeakers should  
not beam the sound directly at the listener. One way of achieving this is  
to use ‘dipole’ Surround speakers which aim the sound down the walls  
rather than directly into the room.  
Now rotate the VOLUME/SETUP knob until REAR 0mS (current delay setting  
for Surround Speakers) appears in the display window. Press the SET UP  
button again to change the delay setting. Rotate the VOLUME/SETUP knob  
to change center delay adjustment in 1mS increments from 0mS to 15mS  
in Dolby Digital mode, or 15mS to 30mS in Dolby ProLogic mode. Press SET  
UP button again to exit Rear delay adjustment.  
Now rotate the VOLUME/SETUP knob until EXIT appears in the display  
window. Press the SET UP button again to exit DELAY SETTING MENU.  
Press the SET UP button again to exit SET UP MENU. Your speaker  
settings are now complete. If in the future you add, change, or move  
speakers, this setup procedure should be repeated.

TIPS FOR SETTING DELAY  
The Channel Balance for each speaker can be adjusted in 1dB  
increments. Continue to calibrate the level for each speaker until equal  
loudness is achieved at your listening position. A more accurate  
adjustment can be made using a sound level meter, if available. Set the  
meter to “Slow” and “C-weighted” modes and re-check the settings  
with the meter placed in several different positions in the general  
listening area.  
Measure the distance from the listening position to the center speaker  
(dC) and to one of the front speakers (dFL or dFR). Subtract the center  
channel distance from the front L or R channel distance. For example, if  
the front speakers are 12 feet (3.7 m) from the listening position and the  
center speaker is 10 feet (3.0 m), the difference is 2 feet (0.6 m). For this  
example the center channel delay is set to 2 milliseconds or ms.  
The T741 can delay the center channel output up to 5 milliseconds and  
thus compensates for center channel speakers that are up to 5 feet  
(1.5m) closer to the listening position than the front left and right  
speakers.  
Press the TEST button again to leave or cancel the Test mode, any  
changes will be memorized automatically.  
Select the channel for which you wish to adjust and set the level so that it  
matches the other speakers. For best results it is best to start with the Left  
channel set at 0dB and to match the other speakers to it. Normally, if the  
Right speaker is located at the same distance from the listening position to  
the Left speaker it should be set at the same level as the Left speaker.  
NOTES  
In rare system setups, the center channel speaker is actually further  
away than the front left and right speakers. In these cases, set the  
center channel delay to 0mS. The center channel delay time  
adjustment is only available in Dolby Digital surround mode.  
NOTE  
If no level adjustments were made, press TEST again to return to the  
selected source. Any changes in the Channel Balance Setting, under  
the test mode, will be memorized automatically.  
Measure the distance from the listening position to either the left or right  
rear speaker (dLS or dRS). Subtract the rear speaker distance from the  
front speaker distance (dFL or dFR). The resulting distance is equivalent to  
the delay in milliseconds for the rear delay setting. For example, if your  
rear speaker distance is 6 feet (1.8 m) and the front distance is 12 feet  
(3.7 m), the correct rear channel delay setting is 6 milliseconds. Again, set  
the rear channel delay to 0mS if the rear channels are further from the  
listening position than the front speakers.  
The Delay time for the Surround speakers also needs to be correctly set  
for your normal listening position. Refer to the section “Channel Delay”  
in this chapter for more information.  
In Dolby Digital surround mode, the rear channel delay time can be set  
from 0ms to 15ms with 1ms increments. In Dolby Pro logic surround mode,  
the rear channel delay time can be set from 15ms to 30ms and 1ms per  
step. In DTS surround mode, the channel delay time cannot be adjusted.  
LEVEL SETTING (CHANNEL BALANCE)  
The output levels of each of the speakers connected to the T741 may  
need to be adjusted so that there is an even balance of sound from all  
the speakers in the system. If, for instance, the relative volume level to  
the Left and Right speakers and the center speaker is set too low, most  
of dialogue may be difficult to follow. If, on the other hand it is set too  
loud, the over-all balance will sound unnatural.  
GB  
To adjust the channel balance, the T741 is equipped with a TEST button  
(No. 7) on the Remote Control to help assess the loudness levels of each  
speaker. Before adjusting the channel balance level, make sure the  
master volume is turned down to a normal listening level.  
Pressing the TEST button engages the Test signal generator to allow for  
adjustment of all speaker levels, so that each channel can be adjusted for  
equal loudness at your listening position. The test signal scrolls  
automatically with 2 second intervals from Left, Center, Right, Rear Right,  
Rear Left, to sub-woofer in continuous cycles. If an adjustment in set-ting  
is made for one of the speakers, scrolling will stop until 2 seconds after the  
adjustment was made. The display panel shows which speaker is being fed  
with the test signal. Use the VOLUME +/- buttons on the Remote Control  
to respectively increase or decrease the level for the current speaker.  
NOTE  
There is no output in the Subwoofer during noise sequencer operation;  
therefore it is difficult to adjust the level in test mode. The Subwoofer  
level can be adjusted in the setup menu with musical input.
