Following are short descriptions of standard built-in C Series protection features:
• CPL (Current Peak Limiter) ensures that the amplier’s output does not exceed the safe current handling
parameters of amplier components.
• Temperature protection ensures that the amplier will not be damaged by exceeding thermal limits.
• PAL (Power Average Limiter) limits the maximum average power consumption according to the power supply
and mains-breaker capabilities.
• VHF (Very High Frequency) protection circuits mute the output of the amplier when nondynamic continuous
signals above 10 kHz are detected.
• DC protection ensures destructive DC signals will not appear at the amplier 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 ampliers are turned on
simultaneously.
2.2.6. NomadLink / Ethernet control and monitoring network
The NomadLink network allows easy setup and control of C Series power ampliers and other devices. The
patented network topology allows automatic detection and addressing of multiple ampliers, 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
ampliers to remain on standby with no power consumption.
Cable connections can be daisy-chained for easier system setup. This also reduces total component costs,
simplies 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 amplier addresses do not need to be
manually entered: you will automatically know where an individual amplier 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 conguration, DeviceControl
provides exible control over very large amplier 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.
