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.

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:

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.
