Naim Audio NAP 500 - Manual (Page 13)

E11
16.1 General Connections Notes
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.
16.2 Protection Notes
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.
16 NAP 100 Installation and Operation
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.
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.
16.3 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.
