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
.
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 CD5
s i 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.
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.
