Lab.gruppen C Series C 10 4X Operation Manual - 4 Welcome
8 C Series C 20:8X, C 10:8X, C 10:4X and C 5:4X Operation Manual
The 35 Hz high-pass filter rolls off low frequencies
(6 dB/octave) for greater efficiency and reliability
in, for example, 70/100 V high impedance systems
where the removal of very low frequency content
may be desired.
4.2.6 NomadLink / Ethernet control and
monitoring network
The NomadLink network allows easy setup and
control of C Series power amplifiers. The patented
network topology allows automatic detection and
addressing of multiple amplifiers. Control is via a PC
running DeviceControl software, which is connected
to the NLB 60E NomadLink Bridge & Network Control-
ler using standard TCP/IP communication. Phantom
powering through the standard Cat-5 network cables
allows the software to detect devices that are not
currently turned on or connected to the mains. This
ensures very high reliability and redundancy levels
while allowing connected amplifiers to remain on
standby with no power consumption.
Cat-5 cable connections can be daisy-chained for
easy system setup. There is no need to create a star
topology using many switches as with, for example,
an Ethernet system. Individual amplifier addresses do
not need to be manually entered: you will automati-
cally know where an individual amplifier resides in
the network. This reduces total component costs,
simplifies installation, and makes daily operation more
convenient.
A daisy chain network loop, in combination with
the automatic addressing of devices, enables
Lab.gruppen’s proprietary DeviceControl software to
automatically create a precise picture of all connected
devices and their relative position in the chain. By
quickly creating a clear overview of the entire system
configuration, DeviceControl provides flexible control
over very large amplifier systems. Setup time is
minimized, and critical information is readily available
for monitoring performance and avoiding problems
during operation.
Via NomadLink, you can monitor all metering data
as well as all faults and warning indications simulta-
neously. NomadLink allows you to remotely power on
and power off individual amplifiers or user-definable
groups of amplifiers, as well as engage Mute and
Solo functions on individual channels.
