2 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.
1 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.
Introduction
Naim Audio products are always conceived with performance as the
top priority and careful installation will help ensure that their full
potential is achieved. This manual begins with statutory safety
warnings and general installation tips for all Naim Audio products.
Product specific information begins in Section 6.
3 Getting Started
3.1 switching on and off
Source components and power supplies for cd players,
tuners, preamplifiers and crossovers should be switched
on before switching on the power amplifier(s). Always
switch the amplifier(s) off and wait about a minute for
the power supply capacitors to discharge before
connecting or disconnecting any leads. Always use the
power switch on the product rather than a mains outlet
switch.
3.2 running in
Your Naim equipment will take a considerable time to run
in before it performs at its best. The duration varies, but
under some conditions you will find that the sound
continues to improve for as much as five weeks. Better and
more consistent performance will be achieved if the system
is left switched on for long periods. It is worth remembering
however that all electronic equipment can be damaged by
lightning. Please read the warnings section.
