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 Equipment Installation
Normally your Naim Audio equipment
will have been installed by the dealer
who sold it to you - even if you live
outside their immediate vicinity. In
any event however your dealer is
responsible for making sure that
the system performs as it should.
Information given here is not intended
to reduce this responsibility in any way.
2 Connections
It is important for both safety and
performance that the standard cables
supplied are not modified.
2.1 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.
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 tend to deposit
may degrade the sound.
3 Mains Power Connection
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.
3.1 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 which is coloured
GREEN-AND-
YELLOW
must be connected to the terminal
in the plug which is marked by the letter
E
or by the safety earth symbol or coloured
GREEN
or
GREEN
and
YELLOW
.
The wire which is coloured
BLUE
must be
connected to the terminal in the plug which
is marked with the letter
N
or coloured
BLACK
.
The wire which is coloured
BROWN
must be
connected to the terminal in the plug which
is marked with the letter
L
or coloured
RED
.
3.2 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.

Introduction
3.3 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 a mechanical hum from power amplifier
and power supply transformers. Naim
transformers are large in size with heavy
gauge windings, 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 improve system performance. Advice
on the installation of a separate mains circuit
should be sought from a qualified electrician.
Do not substitute alternative mains leads and
plugs to those supplied. They are selected to
offer the best possible performance.
4 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.
4.1 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.
Ensure that your equipment rack or table can
easily support the weight and is stable.
4.2 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 power amplifiers
are switched off.
4.3 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.
4.4 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. Systems incorporating
moving coil phono preamplifiers and active
crossovers are more likely to suffer. A radio
frequency filter kit is available for some

Introduction
Naim equipment but sound quality will be
progressively compromised as more elements
of the kit are fitted. In situations of extreme
radio interference Naim equipment may be
unsuitable.
4.5 Non-standard Cables
Use of non-standard speaker cables or
interconnects may invalidate your guarantee.
4.6 Lightning Precautions
Your Naim hi-fi system can be damaged by
lightning. Power amplifiers are particularly
at risk 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.
4.7 Liquid Precautions
Equipment must not be exposed to dripping
or splashing and no objects filled with liquid,
such as vases, should be placed on the
equipment.
4.8 Equipment Fuses
Mains powered Naim Audio equipment is
fitted with a mains input fuse on the rear
panel adjacent to the mains input socket.
Replace it if necessary only with the spare
fuse supplied or with identical fuses.
Repeated failure of this fuse points to an
equipment or system fault that should be
investigated by your dealer or at the factory
by Naim itself.
4.9 Problems?
Consumer protection varies from country to
country. In most territories a dealer 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
dealer. Contact Naim Audio directly for help
and advice if necessary.
4.10 Repairs and Updates
It is essential that repairs and updates are
only carried out by an authorised Naim
dealer 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
