NAP 300
6. NAP 300 Installation and Operation
The NAP 300 and NAP 300PS should be installed on a dedicated equipment stand intended for the purpose and should be
in their nal location before connecting cables or switching on. Switch on the source and preamplier components, with the
volume turned down, before switching on the NAP 300. The NAP 300 power button is located on the front panel of the NAP
300PS Power Supply.
Care should be taken when siting the NAP 300 to ensure that the underside fan inlet and rear outlet are not obstructed.
The NAP 300 and NAP 300PS are heavy and care should be taken when lifting or moving them. Make sure that the surface
they are to be placed on can support the full weight.
6.1 General Connections Notes
The negative input and output connections for each channel
are common. The mains earth (ground) should always be
connected regardless of what other equipment is used in
conjunction with Naim power ampliers. This only grounds
the case and the electrostatic screen within the transformer,
and is not connected to the signal negative. In order to avoid
hum loops, the signal negative of the whole system should
be connected to the mains earth (ground) in one place.
6.2 Protection Notes
In the NAP 300 the fan speed is increased in response to
an increase in amplier dissipation. If the amplier reaches
70°C due to prolonged running at high level or to airow
being blocked, the output will be interrupted and the fan
will run at full speed until it has cooled down. This may take
a few minutes.
It is not necessary to switch the amplier o, but it may be
advisable to mute the preamplier or turn the volume down
to avoid surprises when it comes back on.
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.
6.3 Loudspeaker Cable and Connectors
Only Naim Audio speaker cable should be used to connect
a loudspeaker to the output of the NAP 300. 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.
DAMAGE TO THE AMPLIFIER MAY RESULT IF “HIGH
DEFINITION” CABLE OR ANY OTHER SPECIAL CABLE IS
USED TO CONNECT THE LOUDSPEAKERS.
Ensure when connecting speakers that they are “in phase”.
That is, the positive and negative connection orientation at
both the speaker and amplier ends of the cable is the same
for both channels.
