Power Output Per Channel
Channels 1 thru 4:
50 watts into 4 ohm loads or 100 watts into 2 ohm loads, is
the minimum sine wave continuous average power output
per channel all channels operating.
Channels 5 and 6:
100 watts into 4 ohm loads or 200 watts into 2 ohm loads,
is the minimum sine wave continuous average power out-
put per channel all channels operating.
Power Output Bridged
Channels (1 and 2) or (3 and 4):
200 watts into 4 ohm loads, is the minimum sine wave con-
tinuous average power output with all channels operating.
Channels (5 and 6):
400 watts into 4 ohm loads is the minimum sine wave con-
tinuous average power output with all channels operating.
