1 Connections
It is important for both safety and performance that
the standard cables supplied are not modified.
1.1 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
deposit may degrade the sound.
1.2 Loudspeaker Cables
Loudspeaker cables are vitally important. They 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.
Some Naim amplifiers are designed only to work with
Naim loudspeaker cable and using alternatives may
degrade the performance or even damage the amplifier.
Other Naim amplifiers can be used with any high quality
loudspeaker cable although we recommend that Naim
loudspeaker cable is used. Naim loudspeaker cable is
directional and should be oriented so that the printed
arrow points towards the speakers. The Naim loudspeaker
connectors supplied are designed to comply with
European safety legislation and must be used.
Contact your local retailer or distributor for further advice
on loudspeaker cables and connectors.
2 Mains Power
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.
2.1 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
Naim Audio products are conceived with performance as the top priority. Careful
installation will help ensure that their full potential is achieved. This manual covers the
CD 555, CDS3, CDX2, CD5 XS and CD5i CD players and their associated or upgrade
power supplies. It begins with some general installation notes and statutory safety
warnings. Product specific information begins in Section 4.
the mains lead may not correspond with the coloured
markings identifying the terminals in the plug proceed as
follows:
The wire coloured GREEN-AND-YELLOW must be
connected to the terminal in the plug marked by the
letter E or by the safety earth symbol or coloured GREEN or
GREEN and YELLOW.
The wire coloured BLUE must be connected to the terminal
in the plug marked with the letter N or coloured BLACK.
The wire coloured BROWN must be connected to the
terminal in the plug marked with the letter L or coloured
RED.
2.2 Equipment Fuses
Mains powered Naim Audio equipment is fitted with a
mains fuse on the rear panel adjacent to the mains input
socket. Replace it if necessary only with the spare fuse
supplied or with an identical fuse. Repeated failure of the
fuse points to a fault that should be investigated by your
retailer or Naim itself.
2.3 N o n - r ewirab l e Mains P l u gs
If a non-rewirable plug is cut from a mains lead (for
whatever purpose) the plug MUST 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.
2.4 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
mechanical hum from mains transformers. Some Naim
transformers are large in size, 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
generally improve system per formance. Advice on the
installation of a separate mains circuit should be sought
from a qualified electrician.
Only use the mains leads and plugs supplied or alternative
Naim Audio items.
Introduction

3 General Installation
Naim equipment is designed to offer the finest
performance 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.
3.1 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. Check the
weight of the equipment prior to lifting and if necessary
use more than one person so that it can be moved safely.
Ensure that your equipment rack or table can easily
support the weight and is stable.
Some speakers and stands are intended to be used with
floor spikes fitted. Care should be taken when siting and
moving them to avoid personal injury or damage to
cables and surfaces. Floor protectors are available from
your local dealer or distributor to protect non carpeted
floors.
3.2 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
equipment is switched off.
3.3 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.
3.4 Radio Interference
In some circumstances, depending on where you live
and the earthing arrangements in your home, you may
experience radio frequency inter ference. 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. 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.
3.5 Lightning Precautions
Your Naim hi-fi system can be damaged by lightning
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.
3.6 Problems?
Consumer protection varies from country to country. In
most territories a retailer 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 retailer. Contact
Naim Audio directly for help and advice if necessary.
3.7 Service and Updates
It is essential that repairs and updates are only carried
out by an authorised Naim retailer 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 Customer Services:
Tel: +44 (0)1722 426600
Email: info@naimaudio.com
Please quote the product serial number (found on its rear
panel) in all correspondence.

The digital output is carried by a single 75Ω BNC socket.
Digital and analogue outputs may not be used
simultaneously. Selection is achieved by using the rear
panel mounted switch. The CD5 XS must be switched off
before the output selection switch is operated. Ensure the
correct cables are connected before switching the
CD5 XS back on.
Note: Your local retailer will be able to offer advice on
digital output cables.
15.2 Disc Loading
To load a compact disc pull open the CD drawer using the
handle on the left hand side 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.
Note: If an HDCD® encoded compact disc is loaded the
CD5 XS will automatically recognise and decode it. The
display will read HDCD for a few seconds after play is
pressed.
15.3 Power Supply Upgrade
The CD5 XS analogue output stage can be upgraded
through the addition of an external Flatcap or Hi-Cap
Power Supply. The external supply works with the internal
power supply of the CD5 XS to offer both a greater
number of separate supplies and more sophisticated
voltage regulation. The Power Supply is connected to the
CD5 XS via a five pin DIN cable. Switch off both the power
supply and CD5 XS when making connections. Remove
the link plug and connect the supply cable ensuring that
the connectors are securely attached. Switch on both the
CD5 XS and the power supply from their respective power
buttons.
15.4 Player Maintenance
It is important for reliable operation of the CD5 XS 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 its underside.
Do not, under any circumstances, use any solvents or fluids
for the cleaning process.

CD5i
16 CD5i Introduction and Installation
The CD5i should be installed on a dedicated equipment stand intended for the purpose.
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.
A transit screw on the underside of the CD5i case should be removed before use and
must be replaced if the unit is to be re-packed and shipped. This transit screw must not
be used in any other Naim product. Do not invert the player once the transit screw is
removed.
CD player control and operation is described in Sections 19, 20 and 21.

CD Player Control and Operation
19 CD Player Control and Operation
The operation and control of all Naim CD players is based on a common user interface.
This section of the manual describes the user interface, drawing attention to differences
between players where they occur.
The CD player control buttons are duplicated on the remote control handset which may
also provide some extra functions. The handset also provides CD programming facilities.
See Sections 20 and 21 for more information.
19.1 Player Controls
door: Opens and closes the door (CD 555 only).
disp: Scrolls through the display options of track, time
and display off (CD 555 and CDS3 only).
Note: The CDX2, CD5 XS and CD5i display options can be
scrolled by pressing the remote handset disp key.
prev: Steps through the disc backwards, either one
track at a time, or sequentially if the button is
held.
next: Operates in the same way as the prev button,
but moving forwards instead of backwards.
pause: Pauses play. Pressing pause a second time will
resume play. The pause button indicator will flash
when pause is selected (CD 555 and CDS3 only).
Note: The CDX2, CD5 XS and CD5i can be paused by
pressing the remote handset pause key.
Note: If a player is paused for more than 10 minutes it
will enter a “static pause” mode in which the transport
deactivates to reduce wear. The player can be left in
static pause mode indefinitely. The pause button indicator
will illuminate fully when the player is in static pause mode.
stop: 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
defaults.
play: Plays a disc from track one unless another track
has been selected. Pressing play while a track is
playing will re-start the track.
19.2 Player Control Modes
CD players have an optional control mode. This provides
an alternative inter face in which fast forward and fast
reverse (rather than step forwards and step backwards)
can be selected by pressing and holding the CD player
next and prev buttons respectively. The alternative
interface also provides a pause function on CDX2, CD5
XS and CD5i players selected by pressing and holding the
play button. To select the optional mode press and hold
next while the player switches on. To select the standard
control mode press and hold prev while the player
switches on.
19.3 Player Display and Indicators
The alphanumeric display indicates track and index
numbers, time in minutes and seconds, or system
messages. If a play list is programmed the time displayed
reflects the duration of the programme. Depending on the
model in question, some or all of the indicators described
below will be found adjacent to the display:
HDCD: Indicates that an HDCD encoded disc is playing.
Note: HDCD decoding is not implemented on the CD5i.
repeat: Indicates that repeat has been selected from the
remote handset.
prog: Indicates that a play list has been programmed.
Information on play list programming can be
found in Sections 21.2.
track: Indicates display of number of tracks or current
track.
pause: Indicates that the player is paused.
stop: Indicates that the player is stopped.
play: Indicates that the player is playing.
time: Indicates display of disc time or track time.
19.4 Output Socket Selection
A pair of RCA Phono output sockets are fitted on CD
player rear panels to provide an alternative to the
preferred DIN socket. Proceed as follows to select the RCA
Phono sockets.
With the player stopped, press and hold the remote
handset disp function (handset in CD mode) or, if fitted,
the player disp button until the CD player prog indicator
flashes. Further operations of the disp function will now
cycle through each combination of the two socket types
(DIN only, RCA Phono only or both). The selected option is
indicated on the CD player display as shown below.

NARCOM 4 Handset
21.1 Using NARCOM
Operation of the NARCOM handset is based around three
types of keys: System Component Keys, Global Keys and
Soft Keys.
System Component Keys keys switch the operation of
the Soft Keys into modes appropriate to each system
component (CD player, preamplifier, etc.).
Global Keys operate specific component functions
regardless of the System Component Key setting and are
available at all times.
CD player Global Keys operate as follows:
prev Selects the previous track or index point.
next Selects the next track or index point.
stop Stops cd play.
play Begins cd play.
fwd Fast forwards the cd.
rev Fast reverses the cd.
rpt Repeats the cd or programmed tracks.
pause Pauses the cd.
Soft Keys keys operate, in CD mode (selected by the
System Component Keys), as follows:
numeric: Directly selects tracks or, with the prog key, selects
tracks for play order programming.
prog: Confirms CD track play order selections.
disp: Scrolls through the display options of track, time
and display off.
21.2 Play Order Programming
To program a play order select a track number from the
numeric keys followed by the prog key until the desired
selection is complete. During selection, the track number
indicated in the player display will be followed by either
P or — or no display. P indicates that the track is already
selected, — indicates that the track can be selected.
The prog key can also be used to delete tracks from a play
order. To delete a track, press and hold the prog key until
the prog indicator in the CD display illuminates then delete
the track or tracks using the numeric keys followed each
time by a further operation of the prog key. During deletion
the track number indicated in the player display will be
followed by either C or — or no display. C indicates that the
track is already deleted, — indicates that the track can be
deleted while no display indicates that this is the only track
remaining and therefore cannot be deleted.
21 NARCOM 4 Handset
The NARCOM 4 is a multi-functional remote control handset designed to be used with
Naim Audio CD players, integrated amplifiers, preamplifiers, preset tuners and subwoofers.
