1.0 Equipment installation

Normally your Naim equipment will have been installed by the dealer who sold it to you even if you live outside
their immediate vicinity. Your dealer is responsible for making sure that the system sounds exactly as it should and
information given here is not intended to reduce this responsibility in any way.

1.1 cables and connections

Please do not modify the standard interconnect cables supplied with your Naim equipment. This is important for
safety as well as performance. One end of each cable is marked with a band to establish its correct orientation. The
band always marks the end that connects to the signal source.

Loudspeaker leads are also very important. Naim loudspeaker cable is correct for your system and your dealer will
make up leads to suit your equipment installation. The leads should each be at least 3.5 metres long and of equal
length. The recommended maximum is 20 metres. Loudspeaker leads are, like interconnect leads, directional, and
should be connected so that the printed arrow points towards the speakers. Using alternative loudspeaker cable
will degrade performance, and may even damage your amplifier. An exception to these loudspeaker cable
constraints is the nap 6-50 multi-room power amplifier. The nap 6-50 is designed to be tolerant of both a wide
variety of cable types, and cable runs well in excess of 20m. The loudspeaker connectors supplied with all Naim
amplifiers and loudspeakers have been specifically designed to make a robust mechanical connection. It is essential
that these are used in order to comply with current European safety regulations.

All the plugs and sockets supplied with your Naim equipment have been chosen because they make the best
possible connection for their purpose. A poor contact will degrade the signal substantially and plugs and sockets
should look 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. Special contact cleaners and contact enhancers should
not be used as they tend to deposit a film which is very difficult to remove and may degrade the sound.

2.0 Getting Started

2.1 switching on and off

Source components and power supplies for cd players, tuners, preamplifiers and crossovers should be switched on
before switching on the amplifier(s). Always switch the amplifier(s) off and wait about a minute for its power supply
capacitors to discharge before connecting or disconnecting any leads. Always use the power switch on the product
rather than a mains outlet switch.

2.2 running in

Your Naim equipment will take a considerable time to run-in before it performs at its best. The duration varies, but
under some conditions you will find that the sound continues to improve for as much as five weeks. Better and more
consistent performance will be achieved if the system is left switched on for long periods. It is worth remembering
however that all electronic equipment can be damaged by lightning. Please read the warnings section.

2.3 mains supply

Where fused plugs are used 13 amp fuses should be fitted. Fuses of a lower rating will fail after a period of use. A
hi-fi system usually shares a mains circuit with other household equipment some of which can cause distortion of
the mains waveform. In some Naim equipment such distortion can lead to a mechanical hum from the transformers.
The hum is not transmitted through the speakers and has no effect on the performance of the system but is purely
local to the transformer itself. A separate fused mains circuit (like that reserved for electric cookers) may reduce
transformer hum. Such a circuit (ideally with a 30 or 45 Amp rating) will also have a lower impedance, supply
cleaner power, and consequently improve system performance.

Do not wire voltage dependent resistors or noise suppressors into mains plugs. They degrade the mains supply and
the sound.

2.4 siting the equipment

Power supplies and amplifiers should be located a reasonable distance away from other equipment. This separation
will stop transformer radiation causing hum audible from the loudspeakers. The minimum recommended distance
is 300mm (12 inches), and that allowed by the standard interconnect lead is the maximum.

Some Naim equipment is extremely heavy. Ensure than your equipment rack or table can easily support the weight
and is stable.

2.5 if you have a problem

Legal consumer protection varies from country to country. In most territories a dealer must be prepared to take back
any Naim equipment he has sold you if he cannot make it work to your satisfaction in your own home. A problem
may be due to a fault in any part of the system or its installation so it is essential to make full use of your local
dealer’s diagnostic skills on site. Please contact your local distributor, or Naim at the address in the back of this
manual, 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 guarantee
arrangements with your own dealer at the time of sale. We are always available to offer help and advice.

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 made, tested or matched specially for Naim and appropriate replacements are often
unobtainable from non-specialist sources.
