BRIDGED OPERATION
The KAV-1500 can be reconfigured to bridge four of its amplifier channels to operate
as two combined amplifier channels. The bridged amplifier channels each deliver 1,100
Watts into an 8 Ohm load. The unbridged amplifier channel can be connected to a
separate loudspeaker.
IMPORTANT
One channel must remain unbridged.
