When no VPL, CPL or PAL indicators are illuminated,
and the VPL DIP-switch is set to maximum at the
specified nominal load, the amplifier channel is able
to deliver maximum rated output power.
When the network is connected, the blue NomadLink LED
will illuminate even when mains power is not connected.
NomadLink receives phantom power from the network
supplied by the NLB 60E.
