The AMP-LINK is monitored but not redundant. Therefore, in order to maintain EN54 – IP30 compliance,
the AMP-LINK cable must not be exposed to external field influences and remain fully protected and closed
entirely inside the cabinet of the Impact system.
Amplifiers connected to the AMP-LINK are addressed (numbered) in the same order as they are physically
connected to the controller via an AMP-LINK cable. In the configuration and diagnostic software
information “Amplifier 1” is the first unit on the bus (i.e. the closest and connected directly to the controller),
“Amplifier 2” is the second unit in the chain, etc.
AMP-LINK audio + data bus
Local network
The L-Net daisy-chain topology is dedicated to peripheral devices of the Controller, such as zone-expander
modules or remote microphone stations. The L-Net is used to expand functionality of the Impact system
to remote locations via a powered data bus. Every L-Net port is powered with 24V DC and power over L-
Net is always enabled.
The L-Net capacity of a single Compact 500 unit is limited to the following figures:
Maximum 8 devices per port,
Maximum 16 devices per Controller.
