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 covers the
CD555, CDX2, CD5 XS and CD5si 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.

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. Naim
Hi-Line interconnect cables will provide the best results.

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.

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 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 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.

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
performance. Advice on the installation of a separate mains
circuit should be sought from a qualified electrician.

Use only the mains leads and plugs supplied or the Naim
PowerLine mains cable.

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.

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 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. 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.

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: [phone]
Email: [e-mail]

Please quote the product serial number (found on its rear
panel) in all correspondence.

CD555

4 CD555 Introduction and Installation

The CD555 CD Player can only be operated from a Naim CD 555PS Power Supply. Connection
of the power supply is illustrated in Section 5.2. CD player control and operation is described
in Sections 16, 17 and 18.

The CD555 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.

Seven transit screws on the underside of the CD555 case should be removed before use and
must be replaced if the unit is to be moved or re-packed and shipped. Transit screw locations
are shown, and notes on their removal are provided, below. The transit screws must not be
used in any other Naim product. Do not invert the player while removing the transit screws or
once the transit screws are removed.

The player and power supply should be installed in their final locations before connecting
cables or switching on. Ensure that power amplifiers are switched off and the preamplifier
volume is turned down before the power supply is switched on. The power button is located
on the front panel.

The player and power supply are heavy and care should be taken when lifting or moving
them. Make sure that the surface on which they are to be placed can support their weight.

4.1 Transit Screws

Seven transit screws must be removed from the underside of
the CD555 before use and be replaced if the player is to be
carried any distance, packed or shipped. The transit screw
locations are illustrated in the diagram below. CD555 transit
screws must not be used with any other Naim product.

The player must not be inverted either during or after transit
screw removal.

To gain access to the transit
screws, position one side of
the player over the edge of
a table, remove (or replace)
the screws that become
accessible and then repeat
as necessary with other
sides of the player to access
the remaining screws. If
the transit screws are to be
replaced the three different
types must be used in their
correct locations.

CD Player Control and Operation

16 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 17 and 18 for more information.

16.1 Player Controls

door: Opens and closes the door (CD555 only).

disp: Scrolls through the display options of track, time and

display off (CD555 only).

Note: The CDX2, CD5 XS and CD5si 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 (CD555 only).

Note: The CDX2, CD5 XS and CD5si 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.

16.2 Player Control Modes

CD players have an optional control mode. This provides an
alternative interface in which fast forward and fast reverse

if the R-com is to be packed and shipped.

17.1 Using R-com

R-com keys primarily provide control of the functions most
often used on CD players, preamplifiers, integrated amplifiers
and tuners. In order to extend battery life, R-com will enter a
“sleep” mode when unused. It will “wake” on being touched.

R-com has three operational modes - CD Player mode,
Preamplifier/Integrated amplifier mode and Tuner mode. Its
default mode is CD player. When awake in CD Player mode,
all R-com keys will illuminate green. To switch the R-com into
Preamplifier/Integrated amplifier mode or Tuner mode press
the pre or tun keys respectively. The pre or tun key will then
illuminate white. To switch R-com back into CD player mode
either press the pre or tun key again.

In default mode the R-com keys have the following functions:

disp: Scrolls through the display options of track, time and

display off.

open: Opens the door on the CD555.

stop: Stops CD replay.

play: Begins CD replay.

prev: Selects the previous track or index point.

next: Selects the next track or index point.

vol +: Increases the preamplifier/integrated amplifier

volume.

vol –: Decreases the preamplifier/integrated amplifier

volume.

mute: Reduces the volume to zero. A second press restores

the volume.

pause: Pauses CD replay. A second press restores play.

In Preamplifier/Integrated amplifier mode (press pre key), the
following keys will change function:

disp: Switches the preamplifier/integrated amplifier front panel

button indicators & knob indicators off and on.

NARCOM 4 Handset

18 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.

To fit batteries, remove the battery cover and insert the batteries into the body taking care
with their orientation. Replace the battery cover.

18.1 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.

The CD player can be programmed with a random play order
(from stop with no play order already in place) by pressing prog
followed by 1. Similarly, to program a reverse play order, press

prog followed by 2.

Play orders can be reviewed by pressing prog while the player
is either stopped or playing. The player display will then scroll
through the selected tracks. The prog indicator on the player
display will illuminate when a play order has been programmed.
To clear the program memory press and hold the stop key.

18.2 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.
