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.
However, it is designed to radiate minimal levels of RFI, and accordingly been testing to North American standards
(FCC regulations - limits for a class B digital device pursuant 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 player or other equipment individually, and
checking whether the problem disappears.
•
•
•
•
Re-orientate or relocate the receiving aerial.
Move the CD player away from the receiver.
Connect the CD player to a mains outlet on a different circuit from the receiver.
Consult a dealer or experienced TV/radio technician for help.

GENERAL ADVICE
A1 PRO CD
INSTALLATION PRECAUTIONS and USER INFORMATION
Your new A1 is designed and built to provide trouble-free performance, but as with all electronic devices it is necessary
to observe a few precautions:
Heed all warnings shown on the back of the product.
Only connect the A1 to a mains outlet having the same voltage as marked at the back of the unit.
Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is switched
off.
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 A1, for example, a flower vase or potted plants.
If water does spill inside, 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 A1 is dangerous, and
may cause electric shock or fire hazard.
Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment.
Do not remove any covers or try to gain access to the inside. There are no internal adjustments or fuses you
can replace yourself. Refer all service work to an authorised Musical Fidelity agent.
Note: Unauthorised opening of the equipment will invalidate any warranty claim.
Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agents - they may
harm 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 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 A1 please quote the serial number located on the rear

INSTALLATION
A1 PRO CD
INTRODUCTION
AUDIO CONNECTIONS
Congratulations on the purchase of your new A1 CD
player.
Outputs: Connect your amplifier inputs to the RCA
sockets on the back panel marked as LEFT and RIGHT
outputs.
If desired, the unit can also be attached to an external
DAC of your choice. The unit outputs COAX and
OPTICAL digital signal stream at 44.1kHz.
The A1 CD has extremely low jitter, vanishingly low
distortion, exemplary linearity and ultra low noise. Its
case design complements the A1 series components
which include an integrated amplifier all in the same
convenient size.
Great attention has been paid to internal layout,
isolating each circuit section to prevent possible
interaction.
POWER CONNECTIONS
The unit plugs into mains supply using IEC mains lead.
The connector should fit comfortably when properly
seated.
For added convenience the front panel display and
controls are duplicated on the top next to the mechanism.
This allows easier track selection and control.
The CD digital data streams are first up-sampled to
192kHz, which moves noise, jitter and distortion
artefacts well above the audio band. They are then
passed through a new, low noise, low distortion 24-bit
dual-differential digital-to-analogue converter, which
allows simpler filtering of the analogue output. This in
turn gives an improved audio response without the need
for sharp filters that degrade sound quality. The result is
a CD player which has a smoother response than
previously possible with none of the “hardness” of other
units.
Do not force the connector.
SWITCHING ON
Press the front panel button. The display should light on
the front panel, indicating the unit is ready to use.
CLEANING
Before cleaning the unit, switch off power at the mains
switch and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist
cloth. We do not advise using solvents, white spirit or
thinners as they could damage the surface finish.
The resultant performance achieved by this unit is
among the best in the world. It has excellent signal to
noise ratio, low distortion, wide bandwidth, huge
dynamic range, extraordinary resolution and fine detail.
NOTES ON USING COMPACT DISCS
Always hold discs by the edges and make sure they
remain clean - do not touch the surface. Keep discs away
from direct sunlight and heat sources, such as radiators.
Clean discs with a cloth before playing them, but do not
use solvents such as benzene, thinners, or antistatic spray
intended for analogue records.
After playing, always return the disc to its case for
storage.
INSTALLATION
Position the A1 CD on a stable, horizontal surface
where there is no risk of it being knocked, or subjected
to vibration such as from loudspeakers.
Protect your A1 CD from humidity - if the unit is
moved from a cold place to a warm room, or in generally
humid conditions, moisture can form on the pickup lens
inside the player, preventing the laser beam from reading
the disc. If this happens, remove the CD, close the arm,
and leave the unit switched on for an hour or so to allow
sufficient time for the moisture to evaporate.

REMOTE CONTROL
A1 PRO CD
The universal remote control shown below enables functions from this and related units to be operated from a convenient distance.
Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other functions are only
available by remote control.
As the handset uses an invisible infra-red light beam, the front edge must be pointed directly towards the receiver window at the
front of the player, 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 - two
are required, size AAA, LR03 or SUM-4.
Please dispose of used batteries in accordance to local regulations.

This product contains a PHILIPS CD mechanism, which complies with the PHILIPS/SONY red book
CDDA standard. It is guaranteed to play all disks similarly marked without any problems.
Please note that due to “piracy” concerns, some record companies/pressing plants are creating disks that
do not adhere to this standard. Such disks may –or- may not play in some –or- all CD player products of
any manufacturer. We advise caution in using these disks, as the information contained therein has been
deliberately manipulated and can cause audio degradation and/or playability problems.
We also advise caution with using cheap CD-R, and/or CD-RW disks for audio, and to ensure all home-generated CDs intended for
playback on this unit are recorded as CDDA AUDIO CDs (i.e. not MP3, WAV, AAC etc.) on good quality media.
Remember - the most vulnerable part of a CD playing system is the disc itself. The most likely cause of a disc not playing is that the disc itself is
faulty, scratched or simply dirty. Never open the case of the unit yourself, as this will invalidate the guarantee. If none of the above actions affect
a cure, please contact your dealer or Musical Fidelity service agent.
