Speaker Arrangement - QSC DCM series User Manual

c Speaker Arrangement
In order to do proper Load Fault monitoring, the DCM hardware unit needs to know if
you have wired multiple speakers to an amplifier output. Simply indicate if any speaker
transducers are wired in series or parallel (branches) here so the DCM can compensate
for the impedence changes that this wiring will cause.
For example, if you have two speakers connected in parallel on the output of an amplifi-
er, you would set the banches setting to 2.
IMPORTANT: In the case where an amplifier is in bridge-mono mode, and you have
two speakers connected in parallel, you MUST set BOTH amplifier channels to
BRANCHES = 2 because this is the load impedence seen at BOTH output connections.
Setting these impedences correctly is very important for proper Load Fault detection.
