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:
