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 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  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.

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 strike. 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 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:
