Page 14: Connecting The Kav-1500 Amplifier To Your System
Connecting the KAV-1500 Amplifier to Your System INPUT AND OUTPUT CONNECTIONS Follow these steps to connect the KAV-1500 amplifier to your system. 1. Make sure all power sources and components are off before connecting inputs and outputs= 2. Neatly organize the wiring between the amplifier and all system components. Separate AC wires from audio cables to prevent hum or other unwanted noise from being introduced into the system, 3. - Page 15 The KAV-1500 amplifier is shipped with shorting pins in the XLR inputs. These pins should remain in the XLR inputs if the amplifier is operating in the single-ended mode. When the shorting pin is insert,ed, pins 1 (lower left) and 3 (top) are shorted together. Remove the shorting pins to connect the amplifier for balanced operation.

Page 20: Bridged Operation
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. - Page 21 Connecting the Bridged KAV-1500 See Figure 2 on page 7 Connect the bridged channels as follows: Option 1 1. When the left and right channels are bridged, connect the output cable from the output device to the appropriate balanced (7) or single-ended (12) left channel input. 2.
