Naim Audio HeadLine - Manual (Page 3)

1
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 NAPSC and i-Supply power supplies,
Headline headphone amplifier and Stageline
phono amplifier. It begins with general
installation notes and statutory safety
warnings. Product specific information
begins in Section 5.
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 (i-Supply 3 amp). 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 (not
i-supply). 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 audio.
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
accessories
