IMPORTANT
In order to comply with current European safety regulations
it is essential that the Naim loudspeaker connectors supplied
with amplifiers and loudspeakers are used.
Do not under any circumstances allow anyone to modify your
Naim equipment without first checking with the factory, your
dealer, or your distributor. Unauthorised modifications will
invalidate your guarantee.
For your own safety do not under any circumstances open
Naim equipment without first disconnecting it from the mains.
Warning: an apparatus with CLASS I construction shall be
connected to a mains socket outlet with a protective earthing
connection.
Where the mains plug or an appliance coupler is used as the
disconnect device, the disconnect device shall remain readily
operable. To disconnect the equipment from the mains remove
the mains plug from the mains outlet.
The following label is attached to all mains powered
equipment:
NOTE
This equipment has been tested and found to comply with the
relevant EMC and Safety Standards, and, where applicable,
also complies with the limits for a class B digital device,
pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio
frequency and, if not installed and used in accordance
with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or
television reception, which can be determined by turning
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult your Naim dealer or an experienced radio/TV
technician for help.
WARNING
THIS APPARATUS
MUST BE EARTHED

1
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.
Introduction
Naim Audio products are conceived with performance as the top priority.
Careful installation will help ensure that their full potential is achieved.
This manual begins with general installation notes and statutory safety
warnings for all Naim Audio products. Product specific information begins
in Section 5.
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
GREEN-AND-YELLOW
must be
connected to the terminal in the plug which is marked by the
letter
E
or by the safety earth symbol or coloured
GREEN
or
GREEN
and
YELLOW
.
The wire which is coloured
BLUE
must be connected to the
terminal in the plug which is marked with the letter
N
or
coloured
BLACK
.
The wire which is coloured
BROWN
must be connected to the
terminal in the plug which is marked with the letter
L
or coloured
RED
.
3.2 Non-rewirable Mains Plugs
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.
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.

2
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:
Tel:
[phone]
Email:
ser[email protected]
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
Diagram 7.3
. 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
Section 15
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
previous:
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.
next:
The next button operates in the same way as the
previous button, but moving forwards through the
disc instead of backwards.
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 default
state (track indication).
play:
Plays a disc from track one unless another track has
been selected. Play operated while a track is playing
will re-start the track.
pause:
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.
display:
Scrolls through the display options of “track”, “time”
and display off.

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.

10.6 Power Supply Upgrade
The CD5x can be upgraded through the addition of an external
Flatcap 2 or Hi-Cap Power Supply. The external supply works with
the internal power supply of the CD5x to offer both a greater
number of separate supplies and more sophisticated voltage
regulation. The Power Supply is connected to the CD5x via a five
pin DIN cable. Switch off both the Power Supply and CD5x when
making connections. Remove the link plug and connect the
supply cable ensuring that the connectors are securely attached.
Switch on both the CD5x and the Power Supply from their
respective power buttons.
10.7 Player Maintenance
It is important for reliable operation of the CD5x 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 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.
Do not, under any circumstances, use any solvents or fluids for
the cleaning process.

CD5i
12 Installation and Operation
The CD5i 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.
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. The transit screw location is illustrated in Diagram
14.1. Do not invert the player once the transit screw is removed.
12.1 Disc Loading
Disc loading is illustrated in
Diagram 14.2
. 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. The
illustration in
Section 15
will help identify the correct puck for
the CD5i.
12.2 Player Controls
previous:
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.
next:
The
next
button operates in the same way as the
previous
button, but moving forwards through the
disc instead of backwards.
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, will return the player display to its
default state (track indication).
play:
Plays a disc from track one unless another track has
been selected.
Play
operated while a track is playing
will re-start the track.
All CD control functions are duplicated on the
Flash, NARCOM
3
and
CD5i
remote handsets. The handsets also provide CD
programming facilities. See
Sections 16
,
17
and
18
for more
information.
12.3 Front Panel Control Modes
The CD5i has an optional front panel control mode. This multi-
function mode provides an alternative front panel interface
in which fast forward, fast reverse and pause are selected by
pressing and holding
next
,
previous
and
play
respectively.
To select multi function mode press and hold
next
while the
player is switched on. To select the standard control mode press
and hold
previous
while the player is switched on.
12.4 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. On the far
left of the display are five indicators.
pause:
Flashes to show that pause has been selected
from the remote handset.
Note:
If the CD5i 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 indicator will illuminate fully rather than flash when
the player is in static pause mode.
time:
Illuminates to indicate display of total disc time or
elapsed time of the track being played.
repeat:
Illuminates to show that repeat has been selected
from the remote handset.
prog:
Illuminates to indicate that a program has been
stored. Further information on play list programming
can be found in
Sections 16
,
17
and
18

Flash Handset
17.1 Introduction
Flash is factory pre-programmed to operate any Naim
preamplifier or cd player, the NAT 05 tuner and AV2
audio-visual processor. Additional Naim sources may be
catered for in the future. Contact your dealer or local
representative for information.
Flash is supplied without batteries fitted. To fit the batteries,
remove the battery cover with the supplied hexagon driver and
slide the batteries into the handset body taking care with their
orientation. Replace the battery cover. Do not over-tighten the
fixing screw. With batteries fitted the handset is ready for use.
Flash is designed to switch off if unused after 10 seconds. It
switches on immediately if it is moved or a key is pressed.
17.2 Using Flash
Flash can be set to control each
equipment type through the
four
preset
keys beneath the
display. The selected equipment
mode is indicated in the display
above each
preset
key. When
a
preset
key is pressed the
display and the eight
master
keys and the
numeric
keys will
re-configure appropriately. The
display for each equipment type
shows a representation of the
eight
master
keys and their
functions.
The
AV preset
key will also
wake an av processor from
standby. Press and hold the
AV preset
key to return the
processor to standby mode.
The
volume up
and
down
and
mute
keys are always available
to control the appropriate
(audio-visual or preamplifier)
volume and mute functions
regardless of the selected
source equipment mode.
The
Preamplifier, CD,
and
AV
equipment modes have multiple display “pages” (only one page
is necessary for Tuners). The first display page of each provides
control of the most commonly used functions, with subsequent
pages generally providing access to those less often used.
Selection of second and third pages within each mode is made
by pressing the appropriate
preset
key. The currently selected
page is shown in the top right corner of the display. Details of
the
master
key functions within each page is described in the

18.1 Introduction
NARCOM 3 is a multi-functional remote control handset
designed to be used with Naim Audio CD players,
integrated amplifiers, preamplifiers and preset tuners.
The handset control configuration is based around three
types of keys: System Component Keys, Global Keys and
Soft Keys.
18.2 System component keys
These keys switch
the operation of the
Soft Keys
into modes
appropriate to each
system component
(CD, tuner, preamp,
record).
cd:
Switches the
action of the Soft Keys
to that appropriate for
a CD player.
tuner:
Switches the
action of the Soft Keys
to that appropriate for
a preset tuner.
preamp:
Switches the
action of the Soft Keys
to that appropriate
for an integrated or
preamplifier.
record:
Switches
the action of the
Soft Keys to select
record inputs on
appropriately equipped
preamplifiers.
18.3 Global Keys
These keys operate specific component functions regardless of
the System Component Key setting.
Preamplifier
vol (5 & 6)
Adjusts the preamplifier volume and the volume
control position.
mute
Reduces the preamplifier volume to zero. A second
press restores the volume.
bal (3 & 4)
Adjusts the channel balance. Some Naim
amplifiers have control of channel balance
available only from the remote handset. On these
products the balance will automatically centre
as it reaches the mid point. Centring is indicated
by a flashing volume control indicator. To resume
adjustment once the balance has centred, the
bal
key must be released and re-pressed.
