49 I n sta lla tion a nd Op e ra t io n
The NAP 100 should be installed on a dedicated equipment stand intended for the
purpose and should be in its final location before connecting cables or switching on.
Make sure that the amplifier location allows adequate ventilation. Switch on the source
and preamplifier components, with the volume turned down, before switching on the NAP
100. The NAP 100 power switch is located on the rear panel.

The mains earth grounds only the case and the
electrostatic screen within the transformer and is not
connected to the signal negative. The mains earth must
always be connected to "ground" regardless of any other
equipment used. In order to avoid hum-loops the signal
negative of the whole system should be connected to the
mains earth in one place.
The DIN and RCA signal input sockets are connected in
parallel and should not be used simultaneously.
4 9. 2 P rot ect io n N o t e s
Once installed the NAP 100 is intended to remain
permanently switched on via its rear panel switch. If the
internal heatsink reaches 70°C due to prolonged operation
at high volume levels, the power amplifier circuit will be
disabled until the temperature has fallen.
This may take up to thirty minutes.

OPERATION OF THE AMPLIFIER'S THERMAL PROTECTION
SUGGESTS PROLONGED USE AT TOO HIGH A VOLUME LEVEL.
YOUR LOUDSPEAKERS MAY BE AT RISK IF THIS IS THE CASE. THE
VOLUME SHOULD BE REDUCED.
49.3 Loudspeaker Cable and Connectors
A stereo set of speaker connection sockets is provided on
the rear panel. Custom Naim Audio loudspeaker connectors
are supplied to make the connection and in order to
comply with current European safety regulations these
should always be used. Naim Audio speaker cable will
provide the best results; however, a wide range of speaker
cable types can be used without risk of damage to the
amplifier.
Ensure when connecting speakers that they are "in phase".
That is, the positive and negative connection orientation
at both the speaker and amplifier ends of the cable is the
same for both channels.
