equipment from the mains remove the mains plug from the mains outlet.
The following label is attached to the NAPSC:
wa r n i n g
This apparaTus musT be earThed
This equipment has been tested and found to comply with the relevant EmC and
Safety Standards, and, where applicable, also complies with the limits for a
class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning off and on,
the user is encouraged to try to correct the interference by one or more of
the following measures:
· Reorient or relocate the receiving antenna.
· Increase the separation between the equipment and the receiver.
· Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
· Consult your Naim retailer or an experienced radio/TV technician for help.

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
1
accessories
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 power-Line mains
cable.
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 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. in
situations of
2
accessories
extreme radio interference naim equipment may be unsuitable.
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. 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 naim audio factory. 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:
