7 OPERATION AND PERFORMANCE
7.6.4 Performance, Warning and fault
indicators
Global Indicators:
Figure 7.6.4a: Front panel global LED field
Power on/off
▸
(green) indicates that mains power
is switched on.
NomadLink
▸
(blue) indicates that the network
is connected. The NomadLink LED will light up
even before the mains power is connected and
switched on as it takes phantom power from the
network cable.
PAL
▸
, Power Average Limiter (red), indicates
that the amplifier is limiting because the power
supply and/or the mains-inlet fuse has reached
maximum capability.
Channel Indicators:
Figure 7.6.4b: Front panel LED field
(per-channel)
Bridge mode
▸
(yellow) indicates if two channels
are bridged using the DIP-switch on the rear
panel.
CPL,
▸
Current Peak Limiter (orange), when
flashing indicates the maximum possible current
draw has been reached.
CPL,
▸
Current Peak Limiter (orange), when con-
stant indicates excessive current draw caused
by a short circuit on the output or very low
operational impedance. MUTE LED will illuminate
and the output will mute for 6 seconds before
re-measuring the output impedance. This will
continue until the short circuit is removed. CPL
remains constant orange in a fault condition only
when an input signal is present.
Temperature
▸
(yellow) warning is indicated
by a flashing LED. If the amplifier goes into
thermal protect (output muted), the TEM LED
illuminates constant yellow and the red MUTE
LED illuminates.
Vhf,
▸
Very High Frequency protection (yellow)
indicates that potentially harmful continuous high
frequencies have been detected on the input
signal. The output is muted (MUTE LED on).
hardware fault
▸
is indicated when both the CPL
and TEM, VHF and MUTE indicators light up
simultaneously. The amplifier requires servicing
before placing back in operation.

Figure 7.7.1: NomadLink Network RJ45
connectors
All FP+ Series amplifiers are equipped with the
proprietary NomadLink network interface. This
includes two EtherCon housed RJ45 connections:
one IN and one OUT.
Use standard straight Cat-5 Ethernet cables with
RJ45 connectors to connect the amplifier to the NLB
60E or to daisy-chain multiple amplifiers.
