USER INFORMATION  
RADIO - FREQUENCY INTERFERENCE (RFI)  
This equipment uses and can radiate radio frequency energy, and if not installed and operated in  
accordance with the instructions, may cause interference to radio communications and other  
electronic equipment.  
However, it is designed to minimise RFI, and accordingly been tested to North American stan-  
dards (FCC regulations - limits for a class B digital device persuant to part 15 of the rules).  
These requirements are intended to provide reasonable protection against excessive interference  
in a residential installation.  
Conversely, the product has also been checked to ensure that its own operation is not adversely  
affected by normal background levels of RFI received externally.  
However, if interference is experienced, for instance to radio or TV broadcasts, the user is rec-  
ommended to try one or more of the following measures:  
• Identify the source of interference by turning off power to the CD Pre or other  
equipment individually, and checking whether the problem then disappears.  
• Re-orientate or relocate the receiving aerial.  
• Move the CD Pre24 away from the receiver.  
• Connect the CD Pre24 to a mains outlet on a different circuit from the receiver.  
• Consult a dealer or experienced TV/radio technician for help.  
If a problem persists, please contact Musical Fidelity's service department.

GENERAL ADVICE  
INSTALLATION PRECAUTIONS AND USER INFORMATION  
Your CD Pre24 is designed and built to provide trouble-free performance, but as with all  
electronic devices it is necessary to observe a few precautions:  
* Note all warnings shown on the back of the unit.  
* Only connect the CD Pre24 to a mains outlet having the same voltage as marked on the back  
of  
the unit.  
* Always switch off the mains supply before before connecting or disconnecting your audio  
equipment.  
* Position the mains lead and signal interconnects where they are not likely to be walked on or  
trapped by items placed on them.  
* Do not use near water, or place water-filled containers on the pre-amplifier, for example  
flower vases or potted plants. If water does spill into the equipment, immediately pull out  
the mains plug from the wall socket and inform your dealer, who should then check the  
unit before further use. Entry of liquid into the pre-amplifier is dangerous, and may cause  
electric shock or fire hazard.  
* Do not place the unit near heat sources such as radiators, direct sunlight or above other  
equipment which becomes warm with use. Do not obstruct ventilation slots.  
* Do not remove any covers or try to gain access - refer all service work to an authorised  
Musical Fidelity agent. There are no internal user adjustments.  
NOTE: Unauthorised opening of the equipment will invalidate any warranty claims.  
* There are fuses inside this product. In the unlikely event that one blows, refer the unit to  
your audio dealer.  
Do NOT try to replace the fuse yourself as this will invalidate the warranty.  
* Dust regularly with a soft duster or soft brush. For more thorough cleaning of the cabinet and  
remote control, use a moist cloth. We do not recommend the use of solvents such as white  
spirit or thinners, as they could damage the surface finish.  
* The electronics in modern hi-fi equipment is complex and may, therefore, be adversely  
affected or damaged by lightning. For protection of of your audio system during electrical  
storms, remove the mains plugs and disconnect any aerial lead.  
* If after-sales service is required, to help your dealer identify the CD Pre24, please quote the  
serial number located on the rear panel of the unit.

REMOTE CONTROL  
REMOTE CONTROL  
The remote control enables most functions of the CD pre-amplifier to be operated from a con-  
venient distance.  
Equivalent buttons on the remote handset have the same functions as the those on the front  
panel of the unit.  
Some operations are only available via the handset.  
As the remote control uses an invisible infra-red light beam, the transmitter must be pointed  
directly towards the receiver window on the front of the pre-amplifier, without visual obstruc-  
tion between them.  
If the range of the remote control greatly decreases, replace the batteries with new ones.  
Do not mix old and new batteries - four are required, type SUM-4, AAA or LR03.

CONNECTIONS & PRE-AMPLIFIER OPERATION  
BEFORE CONNECTING . . . . . . .  
The internal D-to-A convertor will also han-  
dle digital data from an external CD or  
DVD audio source.  
Ensure that mains power to the various  
components of your audio system is  
switched off. Please note that audio con-  
necting leads are not supplied with this  
product.  
MAINS POWER CONNECTION  
Insert the accessory IEC mains lead plug  
into the rear panel socket, and then the other  
end into a convenient wall outlet.  
OUTPUT CONNECTION  
The CD Pre24 should be connected to an  
analogue amplifier input by audio cables  
with RCA/phono type plugs. These link the  
left and right PRE OUT sockets on the rear  
panel of the CD Pre to corresponding line  
input sockets on the amplifier. Do not use  
any sockets on the amplifier intended for  
“vinyl” phono cartridge input, as the sensi-  
tive circuit will overload, producing a  
severely distorted sound.  
SWITCHING ON  
Before applying mains power to other audio  
components, check that the volume control  
setting on the CD Pre24 is low (knob turned  
anticlockwise).  
Press the power switch, and the front panel  
display will light to confirm that the unit is  
ready for use.  
Alternatively, the DIGITAL OUTPUTS  
(coaxial or optical) can be used for connec-  
tion to suitable digital equipment.  
INPUT SOURCE SELECTION  
All three types of output can be used for  
feeding different equipment at the same  
time, if required.  
Choose the required input source either by  
pressing the front panel function buttons or  
corresponding buttons on the remote control  
marked LINE 1, 2 or 3, or DIGITAL 1 or 2.  
Note that the volume control only affects  
analogue audio line output to the amplifier,  
not digital or tape outputs.  
The appropriate front panel LED will then  
light to confirm your selection.  
In the case of digital inputs, if no digital  
data is being received at the selected input  
socket, the associated LED will flash instead  
of remaining constant.  
INPUT CONNECTION  
Analogue inputs are provided for three ana-  
logue line sources, and two digital (optical  
or co-axial).  
Turn the volume control to obtain the pre-  
ferred level of sound.  
Do not connect both co-axial and optical  
leads to the same input.  
Connect digital or optical input leads from  
the other audio sources in your system as  
required.

PRE-AMPLIFIER OPERATION  
MUTE (Remote Control Only)  
TAPE MONITOR (Remote Control Only)  
The CD Pre24 can be used in analogue mode  
for off-tape monitoring from 3-head tape  
decks.  
Pressing the MUTE button once on the  
remote control will interrupt analogue out-  
put to the amplifier. Pressing MUTE again  
will restore audio output. The LED in the  
volume control knob then goes off to indi-  
cate that the outputs are muted.  
This allows the user to compare the original  
sound with the recorded version while the  
recording is being made.  
This function does not affect tape monitor  
or digital outputs.  
In this case, the recorder’s left- and right-  
hand line output sockets should be connect-  
ed to the CD Pre’s tape input, and the  
recorder’s line input sockets to the CD Pre’s  
tape output sockets.  
If the CD Pre24 is powered off while still  
muted, the effect will be cancelled when  
next switched on.  
To record, simply select the required source  
with the appropriate button on the CD Pre’s  
front panel or from the remote control.  
Pressing TAPE MONITOR on the remote  
control will allow you to monitor what is  
being recorded, and the matching blue LED  
on the front panel will light to confirm oper-  
ation. Press TAPE MONITOR again to  
cancel this mode.  
DIGITAL MONITORING  
(Remote Control Only)  
Any selected input source can be monitored  
with suitable external equipment from the  
digital co-axial and/or optical output sock-  
ets.  
A digital input source (co-axial only) can be  
monitored by pressing DIGITAL MONI-  
TOR on the remote control. This does not  
affect the selected input source, which will  
still be available from the tape or digital  
outputs.  
On some 3-head tape decks, there is an addi-  
tional “tape / source” switch which should  
be in the “tape” position for this arrange-  
ment to function. If in doubt, refer to the  
recorder’s user manual, or consult your  
dealer.  
This feature may be used together with a  
digital output to connect to a computer  
sound card or CD recorder, providing it has  
digital inputs and outputs.  
If the selected input source is digital (CD or  
DVD audio formats only) a converted ana-  
logue signal will also be available at the  
tape output sockets.  
Note that with this arrangement the CD  
Pre’s volume control has no effect.

CD - BASIC OPERATION  
LOADING AND PLAYING  
COMPACT DISCS  
DISC PLAY  
If PLAY/PAUSE is pressed, the CD player  
will go into play mode, an arrow confirm-  
ing playback will appear on the left, and  
the current track and index point will be  
displayed similar to the following example:  
If mains power to the CD Pre24 is switched  
on with a disc already loaded, it will auto-  
matically search for the disc and begin  
playing from the first track. However,  
playback will not be audible if the input  
has previously been set to another source  
before being switched off. The CD button  
must therefore be pressed first.  
If no disc is loaded, after about 3 or 4 sec-  
onds the unit will display the following:  
Again, the calendar grid shows playback  
progress of the first 20 tracks only.  
When all tracks on the CD have been  
played, playback stops and the display  
reverts to:  
To play a disc, press the OPEN/CLOSE  
button to open the transport drawer.  
When the drawer is fully extended, insert  
the required disc with the label facing  
upwards and then press either the  
OPEN/CLOSE or PLAY/PAUSE button  
to close the transport drawer again.  
PAUSE  
Pressing the PLAY/PAUSE button whilst a  
disc is playing pauses playback of the disc.  
A pause symbol ( ll ) appears in the dis-  
play window next to the play arrow.  
The disc will continue spinning but the  
track does not advance and the CD Pre’s  
output is muted.  
If OPEN/CLOSE is pressed, the disc  
drawer closes and the CD player scans the  
contents of the disc. After a short delay,  
the display window then shows for approx-  
imately 4 seconds the total number of  
tracks available on the CD, and total play-  
ing time, for example:  
Pressing PLAY/PAUSE again resumes  
playback from the same place.  
INDEX POINTS  
Display time 0 on the left then replaces  
the temporary track and time information,  
indicating that a disc is loaded but not yet  
playing.  
Some CDs contain index points within a  
track to separate a musical piece into dif-  
ferent movements. If used, these index  
point numbers (one or two digits, up to 99)  
will appear in the display under the  
graphic. Otherwise, index number 1 will  
be displayed.  
INDEX  
The “calendar” grid pattern at the right-  
hand end of the display also confirms  
tracks available for playing up to the first  
20, but remains displayed. In the above  
example there are 4 tracks on the disc.

back at the beginning of the current track.  
A double-press is needed to jump back to  
the previous track. Corresponding  
TRACK buttons on the remote control are  
also marked |<< and >>|. If either button  
is held down, the CD Pre24 will quickly  
step through the available tracks in the  
required direction.  
DISPLAYING PLAYBACK TIME  
There are three playback time display  
modes accessed progressively by pushing  
the TIME button on the remote control.  
The default mode (e.g. after switch on)  
shown below indicates the elapsed time for  
the currently playing track (2 minutes  
34 seconds in this example):  
Pushing the TIME button once changes  
the display to show the remaining time for  
the current track (4 minutes 29 seconds in  
this example):  
TRACK SELECTION (Remote control)  
A specific track can be selected directly by  
pressing the required track number button  
on the remote control. The chosen track  
then plays immediately.  
To play a track number with two digits,

selected by using the track skip buttons  
( |<< or >>| ).  
The calendar grid to the right of the display  
also confirms this track selection.  
The first ten seconds (approximately) of  
each title on the CD are then played (or the  
first 10 seconds of any programmed titles,  
see below). The playback arrow in the dis-  
play window flashes to indicate that this  
mode is activated.  
Next the second track to be programmed can  
be selected (7 in our example) either by  
entering the required number with the  
numeric buttons or again by using the track  
skip buttons. As the second track number is  
selected the step number will be seen to  
change to a 2 indicating the program step  
being filled.  
Track playing time can be changed to  
approximately 20 or 30 seconds at any time  
during introduction mode. Press INTRO  
twice or three times in quick succession  
instead of once, and the revised time will be  
indicated on the display as:  
or  
If you want to save a track twice in succes-  
sion (for example 9 followed by 9), then  
simply press button 9 twice.  
Press STOP to cancel introduction mode.  
Note: Intro scan time will be memorised as  
long as the unit is powered on, even when  
another disc is loaded.  
Repeat the above procedure by pressing  
remaining track numbers required (9, 9  
again and 12 in our example). Note that as  
tracks are added, the total playing time indi-  
cated increases by a corresponding amount  
plus one second per track. This is to allow  
access time for the CD mechanism during  
the program play sequence.  
PROGRAMMED PLAY / R.M.S.  
The built-in program memory (Random  
Music Selection function) allows you to  
store up to 24 tracks and then play them  
back in the stored order. Each track is  
stored as a 'STEP' in the program.  
If entry of more than 24 tracks is attempted  
accidently, the memory will not accept the  
extra ones. The following is then briefly  
displayed:  
It is possible to store a track more than once  
in the same program if required.  
Example:- You wish to listen to tracks  
14, 7, 9, 9 and 12 in that order on a disc.  
With the disc loaded and the player stopped,  
first press PROGRAM on the remote con-  
trol. The word PROGRAM briefly replaces
