1.0 Equipment installation

Normally your Naim equipment will have been installed by the dealer who sold

it to you even if you live outside their immediate vicinity. Your dealer is

responsible for making sure that the system sounds exactly as it should and

information given here is not intended to reduce this responsibility in any way.

1.1 cables and connections

Please do not modify the standard interconnect cables supplied with your Naim

equipment. This is important for safety as well as performance. One end of each

cable is marked with a band to establish its correct orientation. The band always

marks the end that connects to the signal source.

Loudspeaker leads are also very important. Naim loudspeaker cable is correct for

your system and your dealer will make up leads to suit your equipment

installation. 

The leads should each be at least 3.5 metres long and of equal

length

. The recommended maximum is 20 metres. Loudspeaker leads are, like

interconnect leads, directional, and should be connected so that the printed

arrow points towards the speakers. Using alternative loudspeaker cable will

degrade performance, and may even damage your amplifier. An exception to

these loudspeaker cable constraints is the 

nap 6-50

multi-room power

amplifier. The 

nap 6-50

is designed to be tolerant of both a wide variety of cable

types, and cable runs well in excess of 20m. The loudspeaker connectors supplied

with all Naim amplifiers and loudspeakers have been specifically designed to

make a robust mechanical connection. It is essential that these are used in order

to comply with current European safety regulations.

All the plugs and sockets supplied with your Naim equipment have been chosen

because they make the best possible connection for their purpose. A poor

contact will degrade the signal substantially and plugs and sockets should look

clean and free from corrosion. The easiest way to clean them is to switch off the

equipment, pull the plugs out of their sockets, and push them back in again.

Special contact cleaners and contact enhancers should not be used as they tend

to deposit a film which is very difficult to remove and may degrade the sound.
