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:
