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 standards (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 recommended 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 Pre24away from the receiver.
• Connect the CD Pre24to 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 Pre24is 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 Pre24to 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 convenient 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 obstruction 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 . . . . . . .
Ensure that mains power to the various
components of your audio system is
switched off. Please note that audio connecting leads are not supplied with this
product.
OUTPUT CONNECTION
The CD Pre24should 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 sensitive circuit will overload, producing a
severely distorted sound.
Alternatively, the DIGITAL OUTPUTS
(coaxial or optical) can be used for connection to suitable digital equipment.
The internal D-to-A convertor will also handle digital data from an external CD or
DVD audio source.
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.
SWITCHING ON
Before applying mains power to other audio
components, check that the volume control
setting on the CD Pre24is low (knob turned
anticlockwise).
Press the power switch, and the front panel
display will light to confirm that the unit is
ready for use.
INPUT SOURCE SELECTION
All three types of output can be used for
feeding different equipment at the same
time, if required.
Note that the volume control only affects
analogue audio line output to the amplifier,
not digital or tape outputs.
INPUT CONNECTION
Analogue inputs are provided for three analogue line sources, and two digital (optical
or co-axial).
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.
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.
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.
Turn the volume control to obtain the preferred level of sound.

Instructions for Use. Page 9 of 19
Page 10
PRE-AMPLIFIER OPERATION
MUTE (Remote Control Only)
Pressing the MUTE button once on the
remote control will interrupt analogue output to the amplifier. Pressing MUTE again
will restore audio output. The LED in the
volume control knob then goes off to indicate that the outputs are muted.
This function does not affect tape monitor
or digital outputs.
If the CD Pre24is powered off while still
muted, the effect will be cancelled when
next switched on.
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 sockets.
TAPE MONITOR (Remote Control Only)
The CD Pre24can be used in analogue mode
for off-tape monitoring from 3-head tape
decks.
This allows the user to compare the original
sound with the recorded version while the
recording is being made.
In this case, the recorder’s left- and righthand line output sockets should be connected to the CD Pre’s tape input, and the
recorder’s line input sockets to the CD Pre’s
tape output sockets.
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 operation. Press TAPE MONITOR again to
cancel this mode.
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.
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 analogue signal will also be available at the
tape output sockets.
Note that with this arrangement the CD
Pre’s volume control has no effect.
On some 3-head tape decks, there is an additional “tape / source” switch which should
be in the “tape” position for this arrangement to function. If in doubt, refer to the
recorder’s user manual, or consult your
dealer.

CD - BASIC OPERATION
LOADING AND PLAYING
COMPACT DISCS
If mains power to the CD Pre24is switched
on with a disc already loaded, it will automatically 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 seconds the unit will display the following:
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.
DISC PLAY
If PLAY/PAUSE is pressed, the CD player
will go into play mode, an arrow confirming playback will appear on the left, and
the current track and index point will be
displayed similar to the following example:
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:
PAUSE
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 approximately 4 seconds the total number of
tracks available on the CD, and total playing time, for example:
Display time 0 on the left then replaces
the temporary track and time information,
indicating that a disc is loaded but not yet
playing.
The “calendar” grid pattern at the righthand 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.
Pressing the PLAY/PAUSE button whilst a
disc is playing pauses playback of the disc.
A pause symbol ( ll ) appears in the display 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.
Pressing PLAY/PAUSE again resumes
playback from the same place.
INDEX POINTS
Some CDs contain index points within a
track to separate a musical piece into different movements. If used, these index
point numbers (one or two digits, up to 99)
will appear in the display under the INDEX
graphic. Otherwise, index number 1 will
be displayed.

STOP
Playback can be stopped at any time by
pressing the STOP button once.
TRACK SELECTION
CD - BASIC OPERATION
track time remaining display (far right digits) will be seen to advance rapidly in the
required direction. For both directions the
unit will return to normal playback when
the button is released.
To change track, the track skip buttons
NEXT and PREVIOUS can be pressed
to jump forwards or backwards one track
in either direction. Note that a single press
of the PREVIOUS button restarts playback 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 Pre24will quickly
step through the available tracks in the
required direction.
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,
press the 10+ button on the remote control
followed by the first digit, then the second
digit. For example, to obtain track 27,
press 10+ , then 2, then 7.
SEARCH
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):
Pushing the TIME button again changes
the display to show the remaining time for
the whole disc (33 mins 54 secs) below:
The SEARCH buttons can be used to fastforward or fast-rewind during playback in
a similar way to a video or tape cassette

REPEAT PLAYBACK
The REPEAT button on the remote control
allows the repeated playback of either one
track or all tracks on the disc.
By pressing the REPEAT button once, you
can repeat the entire disc (or the programmed selections - see page 14) over and
over again. Large letters REPEAT briefly
replace track, index and time information
followed by a smaller, permanent REPEAT
legend underneath.
If the REPEAT button is pressed a second
time, only the current track is repeated.
Large letters REPEAT 1 briefly replace
track, index and time information followed
by a REPEAT 1 legend underneath.
Pressing REPEAT a third time cancels
repeat mode. Graphics REPEAT OFF then
briefly replace track, index and time information before reverting to a normal disc
play display.
A-B REPEAT PLAYBACK
“A-B repeat” provides the option of playing
just a certain section of the disc over and
over again.
Find the beginning of the required section
either by listening, or using the display time
as a guide. When the desired starting point
is reached, press button A/B on the remote
control. The display will show REPEAT and
the flashing letter A.
When the disc has reached the end of the
required section, press the A-B button
again. Letters A-B will now be illuminated
in the display, and the unit continuously
plays the selected part of the disc.
To cancel A-B repeat mode, press REPEAT
on the remote control. Graphics
REPEAT OFF then briefly replace track,
index and time information in the display.
SHUFFLE PLAYBACK
The SHUFFLE feature allows tracks on the
discs to be played in random sequence
rather than the normal consecutive order.
Tracks are also played in a different order
each time the disc is restarted, or another
disc loaded.
This function is obtained by pressing
SHUFFLE on the remote control with the
unit either stopped or playing.
If playing, the word SHUFFLE in large letters briefly replaces track, index and time
display information, before a permanent red
indication provides a reminder that the function has been activated.
From stop mode, pressing PLAY/PAUSE
also begins shuffle play.
If the CD Pre24is already playing, play will
continue until either the current track has
finished, or either the track >>| button on
the remote control or NEXT on the unit is
pressed. Shuffle play is then further confirmed by the track number display digits
briefly changing into segments revolving in
a box formation.
If the SHUFFLE button is now pressed for
a second time, the word CONTINUE briefly
replaces track, index and time display information. The unit then resumes normal play
function, except that it now only plays previously unplayed tracks of the current disc,
unless others are then manually selected.
Shuffle play is cancelled by pressing the
STOP button.

track by ear.
Press INTRO on the remote control, and
the display will briefly show:
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 display window flashes to indicate that this
mode is activated.
Track playing time can be changed to
approximately 20 or 30 seconds at any time
during introduction mode. Press INTRO

or
track, index and time information, before a
permanent red display provides a reminder
that the function has been activated.
Press the numeric button of the track number corresponding to the first track you wish
to store (14 in our example is +10, then 4).
That track number will now appear in the
display under TRACK, number 1 (being the
first entry) will appear under STEP, and track
playing time appears under MIN SEC.
Alternatively, the track number can be
selected by using the track skip buttons
( |<< or >>| ).
The calendar grid to the right of the display
also confirms this track selection.
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.
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.
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.
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 control. The word PROGRAM briefly replaces
If you want to save a track twice in succession (for example 9 followed by 9), then
simply press button 9 twice.
Repeat the above procedure by pressing

again and 12 in our example). Note that as
tracks are added, the total playing time indicated 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.
If entry of more than 24 tracks is attempted
accidently, the memory will not accept the
extra ones. The following is then briefly
displayed:

To cancel this mode, press PROGRAM.
The word CONTINUE then briefly replaces
track, index and time display.
Note: The entire program contents will be
cleared if you open the disc compartment to
load another disc, but this does not cancel
program mode itself.
AUTOSPACE
The CD Pre’s AUTOSPACE function can
be used to insert 4-second silent spaces in
between each track as it is played back.
This can be useful when making cassette
recordings of CDs. Some cassette
recorders feature a track skip or search
function which uses the silent gap between
tracks to locate each one individually.
However, some CDs do not have long
enough gaps between tracks for this function
to operate properly.
AUTOSPACE can solve this problem.
Pressing the AUTOSPACE button once
activates the function. The legend AUTOSPACE
will appear in the display. In this mode,
once the CD Pre24has reached the end of a
track the AUTO SPACE graphic will begin to
flash and the elapsed time part of the display
will change to count down from four seconds to zero before play of the next track
begins.
When zero is reached the AUTO SPACE legend
stops flashing and play continues at the start
of the next track.
Press AUTOSPACE again to cancel this
mode.
DISPLAY
The CD Pre’s display can be switched off
with the DISPLAY button on the remote
control when a disc is playing.
However, if the button is pressed without a
CD being loaded, or with a disc stopped,
track, index and time displays are briefly
replaced by the word DISPLAY OFF to confirm this mode has been engaged, but the
display remains lit until play is selected.
Pushing the button a second time briefly
shows DISPLAY ON to confirm that the
function has been cancelled.
When in display-off mode, pressing any button will cause the display to return briefly to
confirm the new status before again switching off.

CD TEXT DISCS
CD TEXT
A small number of CDs released for sale
more recently have additional text information contained in the recorded digital data.
The CD Pre24can individually display
either the disc title, artist’s name or track
title with appropriate control commands.
Only CDs which are identified as having
this text feature, either on the
disc’s label or the library case,
will have text function on the
CD Pre24.
When a text disc is first loaded, a red
CD TEXT legend appears in the display
window.
Text is shown on the front display as
follows:
If a title or name has more than twelve characters, the first 12 only will be diplayed
after the title or name has finished scrolling.
With disc playing:
Each press of the TIME button, the display
will cycle between four states:
Original state:
1a: Track title
then, after a few seconds:
1b: Track elapsed time:
When the disc is first loaded:
Initially (1a): Total tracks and total time
then, after a few seconds, (1b):
Then, with each press of the TIME button,
the display will cycle between the two text
states:
2: Main artist’s name:
2: Track remaining time:
3: Disc remaining time:
4: Track title: (original play mode)
1: Return to 1a then 1b,

Other Languages:
A limited number of CD text discs also
have an “other-language” option.
In this case, after loading the disc, the display shows the current or default language
after MULTI has been appeared underneath
the TEXT legend.
If the player cannot read one of the languages identified in the disc’s digital data,
the display will show “(OTHER LANG)”
after loading the text CD.
To change language with a suitable text
disc, before playing the text CD:
CD TEXT - OTHER LANGUAGES
Press the LANGUAGE button on the front
panel. The current operating language will
then appear in the display.
Press NEXT or PREVIOUS on the front
panel, or |<< or >>| on the remote control to find the required language.
Press the LANGUAGE button again to
store the setting.
Notes:
* If a non-text disc is loaded, pressing the
LANGUAGE button has no effect.
* If a text disc which does not have other
languages available is loaded but not play-
ing, when the LANGUAGE button is
pressed “CAN’T SELECT” is displayed
* If the LANGUAGE button is pressed
while playing a multi-language text disc,
the current language is displayed momentarily.
