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:

Tel: +44 (0)1722 426600

Email: info@naimaudio.com

Please quote the product serial number (found on its rear panel)

in all correspondence.
