5.6.3 DCS 422R LF-INPUT SWITCHING
In case of power amp failure, the DCS 422R module switches the LF-signal over to the assigned spare amplifier.
The DCS 422R module provides four balanced input channels (parallel connection via internal jumpers is
possible) and five LF-output channels. Each input offers electronic switching to the corresponding spare channel.
The internally generated pilot tone signal (the generated signal can be switched via software) is summed on the
five electronically balanced output stages. The four FAULT-LEDs
F1
to
F4
(red) indicate channel failure. The
PILOTTON-LED
PT
(green) indicates the pilot tone generator’s state of operational readiness. The
CC
In/Out-
connector allows cascading the LF-signal for the spare amplifier via several DCS422R modules.

Installation Note
The module has to be installed in the DCS 400 base unit in slots 2-10 (counted from left to right).
Caution!
Slot 1 (the slot all the way on the left hand side) has to be equipped with a DCS 421R control module
respectively with a DCS 405R extension module.
The next slots have to be equipped with DCS 422R / DCS 423R modules always in ascending order (from left to
right) and without empty slots in-between.
When installing the module and establishing connections make sure to comply with VDE 0100 and EN 60065
regulations.
