CONNECTING ANTENNAS  
FM INDOOR ANTENNA  
Lead-type FM Antenna  
In an area with strong FM signals, the “T”-type FM antenna provided is sufficient.  
Extend this into a “T” shape and connect the two wires at the base of the “T” to the provided matching  
transformer, as shown. After completing connection, plug the transformer into the “FM 75“ socket.  
Extend the top of the “T” and fix with thumb tacks, or the like, to a wall or window frame for the best  
possible reception.  
(75) provided  
FM OUTDOOR ANTENNA  
In an area where FM signals are weak, it will be necessary to use a 75-ohm unbalanced-type outdoor FM  
antenna. Generally, a 3- element antenna will be sufficient; if you live in an area where the FM signals are  
particularly weak, it may be necessary to use one with 5 or more elements. Connect the coaxial cable of  
the antenna to the matching transformer as shown. After completing connection, plug the transformer  
into the “FM 75“ socket.

AM INDOOR LOOP ANTENNA  
The high-performance AM loop antenna provided with the receiver is sufficient for good reception in most  
areas. Connect the loop antennas wires to the AM antenna terminals as shown.  
Place the antenna on a shelf, for example, or hang it on a window frame, etc., in the direction which gives  
the best reception, as far away as possible from the entire system, speaker cords and the power cord, to  
prevent unwanted noise.  
AM OUTDOOR ANTENNA  
If the AM loop antenna provided does not deliver sufficient reception (because you are too far from the  
transmitter or in a concrete building, etc.), it may be necessary to use an outdoor AM antenna.  
Use an insulated wire more than 15 ft (5 m) long, strip one end, and connect this to the terminal as shown.  
The antenna wire should be strung outdoors or indoors near a window.  
For better reception, connect the GND terminal to a reliable ground.  
NOTE  
Even when using an outdoor AM antenna, do not disconnect the AM loop antenna.  
CONNECTING SPEAKER SYSTEMS  
CAUTION  
To avoid damage the speakers by inputting a sudden high-level signal, be sure to switch the power off  
before connecting the speakers.  
Connect the cable from each speaker to the corresponding terminal on the rear of the receiver.  
Most speaker cables have different markings, textures or colors to help you tell the difference between  
negative and positive.  
Be sure to connect the positive (+) terminal on each speaker to the positive (+) terminal on the receiver.  
Similarly, connect the negative (-) terminal on the speaker to negative (-) terminal on the receiver.  
NOTES  
Use speakers with a nominal impedance of 8 ohms or more.  
HOW TO CONNECT

AVAILABLE SURROUND MODES  
When you use the surround function, the sound creates a “live” atmosphere such as that experienced in  
movie theaters, discos, stadiums and concert halls. This unit is provided with the following surround  
modes, which can be selected using the SURROUND MODE switches.  
Select the appropriate surround mode according to the program source.  
Note that surround speakers are needed for the Dolby Pro Logic Surround mode to function, and a  
center speaker is needed for the 3 Stereo mode to function.  
DTS (DIGITAL THEATER SYSTEM)  
Allows you to enjoy 5.1 (or 6) discrete channels of high quality digital audio from DTS program sources  
bearing the  
,
or “HIGH DEFINITION SURROUND” trademark such as discs, DVD and compact  
discs, etc. DTS DigitalSurround delivers up to 6 channels of transparent audio (which means identical to  
the original masters) and results in exceptional clarity throughout a true 360° soundfield. The term DTS is  
a trademark of DTS Technology, LLC. Manufactured under license from DTS Technology, LLC.  
SURROUND MODE  
NOTE  
The DTS program sources should be played back in the DTS mode. If not, it will sound like continuous  
noise.  
DOLBY DIGITAL SURROUND  
The Dolby Digital surround format lets you enjoy up to 5.1 channels of digital surround sound from a Dolby  
Digital program source. If you connect a DVD player equipped with an DOLBY DIGITAL output to the  
DIGITAL (Dolby Digital) / DTS / PCM DIGITAL IN jack on a surround receiver/amplifier or surround  
processor and play DVD with the  
mark, you can enjoy even better sound quality, greater spatial  
accuracy, and improved dynamic range. This is because Dolby Digital delivers up to 5 totally discrete, full  
frequency audio channels (front left and right, center, and surround left and right), plus 0.1 channel called  
LFE (bass-only effects channel).  
Dolby Digital is a system developed by Dolby Laboratories that transmits 5.1 channels of digital signals. The  
surround system developed for movie theaters using this system is called “Dolby SR-D (Surround Digital)”.  
Because each channel is completely independent, a realistic sound field with a “three-dimensional” feel is  
achieved which gives the sound a sense of distance, movement and relative position, creating a surprisingly  
real and powerful sense of presence.  
Some Dolby Digital programs carry information that allow you to compress the dynamic range of sound  
track, without degrading the sound quality, for softer sound effects when you listen late at night.  
LFE: LOW FREQUENCY EXTENSION  
This channel delivers separate non-directional bass signals to the subwoofer for more dynamic deep bass  
sound effects.  
GB  
DOLBY PRO LOGIC SURROUND  
Use this mode when playing movie or music video software which carries the  
DOLBY SURROUND  
mark. This mode provides the effect of being in a movie theater or live concert house-an effect with an  
intensity which can only be obtained through DOLBY PRO LOGIC SURROUND. The main feature of DOLBY  
PRO LOGIC SURROUND is that the separation between the various channels is significantly improved from  
the 3 dB of previous systems to 26-40 dB.  
As a result, the effect of the front/back/ left/right movement of the sound image, as well as the sense of  
fixed position in the sound image, is much clearer and more dynamic than before.  
In addition, movie dialogue and other sounds which should naturally be heard from the center are output  
through an independent center channel, providing a high degree of focus for dialogue.  
15  
 
AVAILABLE SURROUND MODES  
3 STEREO  
Front speakers receive rear (surround) speaker signals in addition to front speakers signals.  
Center speaker works similarly as that of Dolby Pro Logic mode. In this way, you can enjoy playback sound  
having superior sound positioning.  
HALL SURROUND  
When playing recordings of live music, this mode provides a feeling similar to actually being in a concert  
hall. When this mode is selected, the normal program source is directed to the main speakers and a  
reverberated sound is directed to the surround speakers. This mode is suited to program sources which  
contain a large amount of reverberation.  
STEREO  
When playing movie or music with 5.1 channels through Dolby Digital or DTS, selecting STEREO MODE  
will down-mix the multi-channel signal to 2-channel stereo. VFL Display will show ‘Dolby stereo’ icon or  
‘DTS stereo’ icon.

SPEAKER POSITIONING  
Front  
Speakers  
The installation positions of speakers differ according to the size, and acoustics of the listening room. While  
actually listening to a program source, try various speaker positions to determine which layout provides the  
best surround effect.  
Center Speaker  
Subwoofer  
Front speakers Place to the front left and right of the listening position. Front speakers are required  
for all surround modes.  
Center speaker Place front and center. This speaker stabilizes the sound image and helps recreate  
sound motion. Be sure to connect a center speaker when using the 3 STEREO mode.  
Rear speakers Place to the direct left and right. These speakers recreate sound motion and  
atmosphere. Required for surround playback. For best results, do not install the rear speakers too far  
behind the listening position and install them above the level of the listeners ears. It is also effective to  
direct the rear speakers towards a wall or ceiling to further disperse the sound.  
Subwoofer Reproduces powerful deep bass sounds.  
Rear Speakers  
Speaker layout example when using  
SURROUND MODE  
SPEAKER CONFIGURATION  
Refer to OSD speaker configuration. (page 17)  
It is important to perform speaker configuration prior to using the decoder. This allows the unit to sense  
the available speakers and automatically select decoding modes. It is possible to receive multi-channel  
surround sound without a center speaker, but for best results with Dolby Pro Logic and Dolby Digital  
decoding, at least 5 speakers (Left, Center, Right, Left Rear and Right Rear) should be used.  
CENTER SPEAKER MODE  
LARGE: Use this mode with a large center speaker. The center channels output is full range.  
SMALL: Use this mode with a small center speaker. Bass frequencies below 90 Hz are output from the  
speaker selected by LFE/Bass Out.  
NONE: Use this mode if there is no center speaker. The center channel signal will be divided between  
the main L and R speakers.  
REAR (SURROUND) SPEAKER MODE  
LARGE: The mode to choose if a large speaker is used or if a subwoofer is connected in parallel. The  
rear channels full range is output as is.  
GB  
SMALL: The mode to choose if small speakers are used. Frequencies of 90Hz and below are output to  
the speaker selected by LFE/Bass Out.  
FRONT SPEAKER MODE  
LARGE: The mode to choose if a large speaker are installed. Front channels full range is output as is.  
SMALL: The mode to choose compact speakers. Frequencies of 90Hz and below are output to the  
speaker selected by LFE/Bass Out.  
SUBWOOFER OUTPUT  
SUB-ON: The mode to choose if a subwoofer is used. Low frequencies of 90Hz and below in the LFE  
channel and other selected channels are output to the subwoofer.  
SUB-OFF: The mode to choose if no subwoofer is used. Low frequencies of 90Hz and below in the LFE  
channel and other selected channels are distributed between the front L and R speakers.

SURROUND EFFECTS  
DELAY TIME  
Refer to OSD surround mode. (page 17)  
When you adjust the delay time in the DOLBY DIGITAL mode, an additional 15 ms is automatically added  
to the surround channels in the DOLBY PRO LOGIC mode. The current setting is shown on the display.  
DELAY TIME SETTING  
Adjustable Range  
DOLBY DIGITAL Mode:  
0 ~ 15 ms in 1 ms step (S-Delay)  
0 ~ 5 ms in 1 ms step (C-Delay)  
DOLBY PRO LOGIC Mode:  
15 ~ 30 ms in 1 ms step (S-Delay)  
In the surround modes, the sound from the rear speakers should be delayed slightly, relative to that from  
the front speakers. The optimum delay time will depend on acoustic properties, whether the walls and  
furnishings reflect or absorb sound, etc.  
It is recommended that you try different delay times to obtain the best effect. The delay is digitally  
synthesized, for the highest sound quality with minimum noise and distortion. The delay time can be set  
independently for each surround mode using the DELAY TIME buttons, with the current setting shown in  
the display.
