1 Con n ec t ion s
It is important for both safety and performance that
the standard cables supplied are not modified.
1.1 In t e rc o n nec t C a b le s
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
deposit may degrade the sound.
1.2 Lo u d sp e a ker Ca b l es
Loudspeaker cables are vitally important. They should
each be at least 3.5 metres long and of equal length. The
recommended maximum is normally 20 metres although
longer cables may be viable with some Naim amplifiers.
Some Naim amplifiers are designed only to work with
Naim loudspeaker cable and using alternatives may
degrade the performance or even damage the amplifier.
Other Naim amplifiers can be used with any high quality
loudspeaker cable although we recommend that Naim
loudspeaker cable is used. Naim loudspeaker cable is
directional and should be oriented so that the printed
arrow points towards the speakers. The Naim loudspeaker
connectors supplied are designed to comply with
European safety legislation and must be used.
Contact your local retailer or distributor for further advice
on loudspeaker cables and connectors.
2 Mai n s Po w er
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 Ma i n s P lu g W i r in g
In some territories a mains plug may need to be fitted
to the supplied mains lead. As the colours of the wires in
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 all power supplies. It begins with some general installation notes and statutory safety warnings. Product specific information begins in Section 4.
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 Eq u i pm e n t F use s
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 No n - re w i rab l e M a in s P l u gs
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 Ma i n s C ir c u its a n d C a ble s
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 per formance. 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.

3 Gen e ra l I nst a ll a t io n
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 Si t i ng Th e E q u ip m e n t
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.
Some speakers and stands are intended to be used with
floor spikes fitted. Care should be taken when siting and
moving them to avoid personal injury or damage to
cables and surfaces. Floor protectors are available from
your local dealer or distributor to protect non carpeted
floors.
3.2 Sw i t ch i n g O n
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
equipment is switched off.
3.3 Ru n n in g I n
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 Ra d i o I nt e r fer e n ce
In some circumstances, depending on where you live
and the earthing arrangements in your home, you may
experience radio frequency inter ference. 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 extreme
radio interference Naim equipment may be unsuitable.
3.5 Li g h tn i n g P rec a u ti o n s
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 a lightning strike. For complete
protection all mains plugs and any aerial cables should be
disconnected when not in use.
3.6 Pr o b le m s ?
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 Se r v ic e a n d U p da t e s
It is essential that repairs and updates are only carried
out by an authorised Naim retailer 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 Customer Services:
Tel: +44 (0)1722 426600
Email: info@naimaudio.com
Please quote the product serial number (found on its rear
panel) in all correspondence.
