When connecting amplifier outputs to 100V section at the terminals, ensure the polarity of termination is correct. This is
to avoid short circuit which may damage the amplifier.
Amplifier output must be connected to IN terminals, and the outgoing to Zone Selector at OUT sections. Reversing them
will cause AX3800 to treat the channel as failed.
Each output of the amplifier must be terminated for monitoring. A disconnected channel shall be deemed fail.
For unused channels :
It is quite common that not all channels will be utilised in a system. Switch off the unused channel with corresponding
switch at DIP Switch.
