7 OPERATION AND PERFORMANCE
7.6.4 Performance, Warning and fault
indicators
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.
CPL, Current Peak Limiter (orange), when flashing
•
indicates the maximum possible current draw
has been reached.
CPL, Current Peak Limiter (orange), when constant
•
indicates excessive current draw caused by a
short circuit on the output or very low operational
impedance. When detected, 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 LED illuminates
constant yellow.
Vhf, Very High Frequency protection (yellow),
•
indicates that potentially harmful continuous high
frequencies have been detected on the input
signal. The output is muted.
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.
hardware fault is indicated when both the CPL
•
and VHF indicators light up simultaneously. The
amplifier requires servicing before placing back
in operation.
