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.
