▸
DC protection
ensures destructive DC signals will not appear at the amplifier outputs. If such conditions
occur an internal fuse opens and fault indication is displayed.
▸
Low impedance
(short circuit) protection provides a fault warning indication and shuts down the output
stage when, for example, an input signal is present and a malfunctioning cable or driver is short circuiting
the output.
▸
High impedance
warning reports an alert when, at the same time, output signal is high and no current
draw is measured. This situation might occur when no speakers are connected, or when a driver is blown.
▸
Low inrush current
ensures that the mains breaker will not trip when several power amplifiers are turned
on simultaneously.
2.2.5 NomadLink / Ethernet control and monitoring network
The NomadLink network allows easy setup and control of C Series power amplifiers and other devices. The
patented network topology allows automatic detection and addressing of multiple amplifiers, and is controlled
from a PC via an NLB 60E NomadLink Bridge & Network Controller using standard TCP/IP communication.
Phantom powering through the 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.
Cable connections can be daisy-chained for easier system setup. This also reduces total component costs,
simplifies installation, and makes daily operation more convenient. 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 automatically know where an individual amplifier resides in the network.
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 configu-
ration, DeviceControl provides flexible control over very large amplifier systems. Set-up time is minimized, and
critical information is readily available for monitoring performance and solving problems during operation.
Via NomadLink, you can simultaneously monitor all metering data as well as any fault or warning indications..
NomadLink also allows you to remotely control power on and power off, as well as engage Mute and Solo
functions on individual channels.
