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 Nomad-
Link LED will illuminate even when mains power is
not connected. NomadLink receives phantom
powerfrom the NLB 60E over the network cable.
