Naim Audio NAT05 XS - Manual (Page 3)

E1
Naim products are conceived with performance as the top priority. Careful
installation will help ensure that their full potential is achieved. This manual covers the
NAT05 XS FM tuner. It begins with some general installation notes and statutory safety
warnings. Product specific information begins in Section 4.
Introduction
1 Connections
It is important for both safety and performance that
any standard cables supplied are not modified.
1.1 Analogue Audio Interconnect Cables
If options are available with your equipment and
installation, DIN interconnect sockets should be used in
preference to phono sockets. One end of each Naim
audio 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.
Audio 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 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.
Only use either the mains cable and plugs supplied or a
Naim Power-Line mains cable.
