1:1 or 3:1 channel failover is triggered by one of the following conditions:
•
Heatsink fault (over temperature)
•
Short circuit fault • Channel failure fault
•
ELD-1/speaker line fault if enabled in software
The redundant channel may be wired in parallel to the existing speaker line or connected to a redundant
speaker line. The primary amplifier module will resume control after the fault condition is cleared and the
unit is re-powered.
