2 Audio Connections
It is important for both safety and performance that
the standard cables supplied are not modified.
2.1 Interconnect Cables
If options are available with your equipment and installation,
DIN interconnect sockets should be used in preference to RCA
Phono sockets. One end of each Naim interconnect cable is
marked with a band to establish its correct orientation. The band
denotes the end that connects to the signal source.
Interconnect plugs and sockets should be kept clean and free
from corrosion. The easiest way to clean them is to switch off
the equipment, pull the plugs out of their sockets, and push
them back in again. Contact cleaners and “enhancers” should
not be used as the film they tend to deposit may degrade the
sound.
2.2 Loudspeaker Cables
Loudspeaker cables are vitally important and your dealer should
make them up to suit your installation. The cables should
each be at least 3.5 metres long and of equal length. The
recommended maximum is normally 20 metres although longer
cables may be viable with some Naim amplifiers. Contact your
dealer or Naim Audio for advice.
Many Naim amplifiers are designed only to work with Naim
loudspeaker cable and using alternatives may degrade the
performance or even damage the amplifier. Naim loudspeaker
cable is directional and should be oriented so that the printed
arrow points towards the speakers. The amplifier/loudspeaker
connectors supplied are designed to make a robust electro-
mechanical connection and to comply with European safety
regulations. They should be used in preference to alternatives.
3 Mains Power Connection
Where fused plugs are used 13 amp fuses should be
fitted. Fuses of a lower rating will fail after a period
of use. Do not wire voltage dependent resistors or
noise suppressors into mains plugs. They degrade the
mains supply and the sound.
1 Equipment Installation
Normally your Naim Audio equipment will have been installed by the dealer who sold
it to you - even if you live outside their immediate vicinity. In any event however
your dealer is responsible for making sure that the system sounds as it should.
Information given here is not intended to reduce this responsibility in any way.

3.1 Mains Plug Wiring
In some territories a mains plug may need to be
fitted to the supplied mains lead. As the colours of
the wires in the mains lead may not correspond with
the coloured markings identifying the terminals in the
plug proceed as follows:
The wire which is coloured
must be
connected to the terminal in the plug which is marked by the
letter
or by the safety earth symbol or coloured
or
YELLOW
.
The wire which is coloured
must be connected to the
terminal in the plug which is marked with the letter
or
coloured
.
The wire which is coloured
must be connected to the
terminal in the plug which is marked with the letter
or coloured
.
3.2 Non-rewirable Mains Plugs
If a non-rewirable plug is cut from a mains lead (for whatever
purpose) the plug
be disposed of in a way to render it
totally useless. Considerable shock hazard exists if the cut-off
plug is inserted into a mains outlet.
3.3 Mains Circuits and Cables
A hi-fi system usually shares a mains circuit with other
household equipment some of which can cause distortion of the
mains waveform. This distortion can in turn lead to a mechanical
hum from power amplifier and power supply transformers.
Naim transformers are large in size with heavy gauge windings,
making them relatively sensitive to such distortion, and it may
be necessary to take account of transformer hum when siting
your equipment.
Transformer hum is not transmitted through the speakers and
has no effect on the performance of the system; however, a
separate mains circuit may reduce it. Such a circuit (ideally with
a 30 or 45 Amp rating) will also improve system performance.
Advice on the installation of a separate mains circuit should be
sought from a qualified electrician.
Do not substitute alternative mains leads and plugs to those
supplied. They are selected to offer the best possible audio
performance.
4 General Installation
Naim equipment is designed to offer the finest sound
quality possible avoiding compromise wherever
practical. This can lead to circumstances that may
be unfamiliar. The notes that follow contain advice
specifically related to Naim equipment as well as
more general warnings about the use of domestic
audio products. Please read them carefully.
4.1 Siting The Equipment
In order to reduce the risk of hum audible from the
loudspeakers, power supplies and power amplifiers should be
located a reasonable distance away from other equipment. The
maximum separation distance for connected equipment is that
allowed by the standard interconnect lead.
Some Naim equipment is extremely heavy. Ensure that your
equipment rack or table can easily support the weight and is
stable.
4.2 Switching On
Source components and power supplies should be switched on
before the power amplifiers. Always switch amplifiers off and
wait a minute before connecting or disconnecting any leads.
Always use the power switch on the product rather than a mains
outlet switch.
A “thump” may be heard from the loudspeakers as power
amplifiers are switched on. This is normal, will not cause any
loudspeaker damage and does not point to any fault or problem.
A mild “pop” may also be heard shortly after power amplifiers
are switched off.
4.3 Running In
Naim equipment takes a considerable time to run in before
it performs at its best. The duration varies, but under some
conditions the sound may continue to improve for over a month.
Better and more consistent performance will be achieved if
the system is left switched on for long periods. It is worth
remembering however that equipment left connected to the
mains can be damaged by lightning.
4.4 Radio Interference
In some circumstances, depending on where you live and the
earthing arrangements in your home, you may experience
radio frequency interference. Controls on broadcasting in some
territories allow very high levels of radio frequency radiation
and both the choice and exact siting of equipment may be
critical. Susceptibility to radio frequency interference is related
to the wide internal bandwidth necessary for high sound quality.
Systems incorporating moving coil phono preamplifiers and
active crossovers are more likely to suffer. A radio frequency
filter kit is available for some Naim equipment but sound quality
will be progressively compromised as more elements of the
kit are fitted. In situations of extreme radio interference Naim
equipment may be unsuitable.
4.5 Non-standard Cables
Use of non-standard speaker cables or interconnects may
invalidate your guarantee.
4.6 Lightning Precautions
Your Naim hi-fi system can be damaged by lightning. Power
amplifiers are particularly at risk and should be turned off and
disconnected from the mains when there is risk of lightning
strike. For complete protection all mains plugs and any aerial
cables should be disconnected when not in use.
4.7 Liquid Precautions
Equipment must not be exposed to dripping or splashing and no
objects filled with liquid, such as vases, should be placed on the
equipment.
4.8 Equipment Fuses
Mains powered Naim Audio equipment is fitted with a mains
input fuse on the rear panel adjacent to the mains input socket.
Replace it if necessary only with the spare fuse supplied or
with identical fuses. Repeated failure of this fuse points to an
equipment or system fault that should be investigated by your
dealer or at the factory by Naim itself.
4.9 Problems?
Consumer protection varies from country to country. In
most territories a dealer must be prepared to take back
any equipment he has sold if it cannot be made to work
satisfactorily. A problem may be due to a fault in the system or
its installation so it is essential to make full use of your dealer’s
diagnostic skills. Please contact your local distributor, or Naim
Audio directly, if any difficulties cannot be resolved.
Some Naim equipment is made in special versions for
different territories and this makes it impracticable to arrange
international guarantees. Please establish the local guarantee
arrangements with your dealer. Contact Naim Audio directly for
help and advice if necessary.
4.10 Repairs and Updates
It is essential that repairs and updates are only carried out
by an authorised Naim dealer or at the factory by Naim itself.
Many components are custom made, tested or matched and
appropriate replacements are often unobtainable from other
sources.
Direct contact to Naim for service or update information should
be made initially through the Service Department:

Please quote the product serial number (found on its rear panel)
in all correspondence.
Introduction
CDS3
5 Installation and Operation
The CDS3 CD Player can only be operated from a Naim XPS Power Supply. Connection of
the power supply is illustrated in Diagram 6.2
The CDS3 should be installed on a dedicated equipment stand intended for the purpose.
To improve sound quality the player has hard metallic feet which may blemish any
delicate surface on which it is placed. Do not stand the player directly on top of another
item of Naim Audio equipment. Care should be taken to ensure that the player is level.
Transit screws on the underside of the CDS3 case and beneath its transport lid should
be removed before use and must be replaced if the unit is to be moved or re-packed
and shipped. The transit screw locations are illustrated in Section 7. The transit screws
must not be used in any other Naim product. Do not invert the player once the transit
screws are removed.
5.1 Disc Loading
Disc loading is illustrated in
. To load a compact
disc lift the transport lid from the front of the player. Place the
disc on the platter followed by the magnetic puck. Do not use a
puck from any other Naim CD player. Different Naim CD players
use dissimilar pucks. The illustration in
will help
identify the correct puck for the CDS3.
If an HDCD® encoded compact disc is loaded the CDS3 will
automatically recognise and decode it. The display will read
HDCD for a few seconds after play is pressed.
5.2 Player Controls
With a disc loaded but not playing, the previous
button searches the disc contents backwards, either
one track at a time, or sequentially if the button
is held. While a disc is in play, the previous button
searches the table of contents backwards. Play
resumes with the selected track when the button is
released.
The next button operates in the same way as the
previous button, but moving forwards through the
disc instead of backwards.
Stops play and resets the player to its start
condition. Pressing and holding stop will clear
any programmed play order, or, if no play order is
programmed, return the player display to its default
state (track indication).
Plays a disc from track one unless another track has
been selected. Play operated while a track is playing
will re-start the track.
Pauses play. Pressing pause a second time will
resume replay. If play is selected while the player
is paused, replay will resume at the start of the
paused track when pause is deselected. The pause
button indicator will flash when pause is selected.
If the CDS3 is paused for more than 10 minutes it will enter a
“static pause” mode in which the transport laser deactivates and
the disc stops spinning - so reducing wear on the transport. The
player can be left in static pause indefinitely. The pause button
indicator will illuminate fully rather than flash when the player is
in static pause mode. Pressing the pause button will deselect
static pause. Replay will resume at the pause point.
Scrolls through the display options of “track”, “time”
and display off.
All CD control functions are duplicated on the
and
remote handsets. The handsets also provide CD
programming facilities. See
,
and
for more
information.
5.3 Front Panel Control Modes
The CDS3 has an optional front panel control mode. This multi-
function mode provides an alternative front panel interface in
which fast forward and fast reverse can be selected by pressing
and holding
and
respectively.
To select multi function mode press and hold
while the
player switches on. To select the standard control mode press
and hold
while the player switches on.
5.4 Player Display and Indicators
The alphanumeric display indicates track and index numbers,
time in minutes and seconds, or various system messages
(Error, Track programming info, etc). The full stop on the right of
the display window illuminates when the player receives a signal
from the remote handset. If a track play list is programmed the
time displayed reflects the duration of the program. Above the
display are four indicators.
Illuminates to show that an HDCD encoded disc
is playing.
time:
Illuminates to indicate display of total disc time
or elapsed time of track being played.
Illuminates to show that repeat has been
selected from the remote handset.
Illuminates to indicate that a program has been
stored. Further information on play list programming
can be found in

5.5 Output Socket Selection
A pair of phono output sockets are fitted at the rear of the CDS3
to provide an alternative to the preferred DIN socket. Proceed as
follows to select the phono sockets.
With the player stopped, press and hold the remote handset
function (handset in CD mode) or front panel
button
until the CD player prog indicator flashes. Further operations of
the
function will now cycle through each combination of the
two socket types (DIN only, phono only or both). The selected
option is indicated on the CD player display as shown below.
Press and hold the
function a second time to exit from
socket selection mode.
5.6 Player Maintenance
It is important for reliable operation of the CDS3 to ensure that
the surfaces of the transport platter and the underside of the
puck are free of dust or debris which can prevent the disc from
sitting properly and cause it to slip.
To clean the transport platter, take a piece of Blu-tack and
lightly apply it to the top surface of the magnetic metal hub,
picking up any material attached to it. Brush the plastic outer
edge lightly with your finger or a soft brush to ensure that it is
dust and particle free. Similarly, clean the puck with Blu-tack,
to remove debris from the three locating pins on its underside.
Take care not to damage the rubber pressure pads. Brush them
lightly with your finger or a soft cloth.
Do not, under any circumstances, use any solvents or fluids for
the cleaning process.
