Operation and Performance

▸
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 six
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 frequen-
cies 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 being placed back in operation.
5.7 NomadLink network and DeviceControl software
5.7.1
NomadLink network in the amplifiers
All C Series amplifiers are equipped with the proprietary NomadLink network interface. This includes two RJ45
connections in standard housings: one IN and one OUT.
Use standard straight Cat-5 Ethernet cables with RJ45 connectors to connect the amplifier to the NLB 60E
NomadLink Bridge and Network Controller or to daisy-chain multiple amplifiers.
It is very important never to connect an IN port to
another IN port or an OUT port to another OUT port.
This will cause the NomadLink communication and
DeviceControl software to exhibit erratic behavior
and display inaccurate data. However, this situation
will not damage the amplifier circuitry.
Up to 60 amplifiers can be connected to one NLB 60E in a daisy-chain or closed loop. In systems that consist
of C...X Series as well as standard C Series or FP+ amplifiers, each C...X unit should be counted as two devices
on the network, with the total device count not to exceed 60 devices per subnet.
