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: +44 (0)1722 426600
Email: info@naimaudio.com
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.
