Configuring The Kav-250A For Bridged Operation - Krell Industries Amplifier KAV-250a Owner's Reference Manual

Configuring the KAV-250a
for Bridged Operation
The KAV-250a may be configured to operate
in a bridged mode. When bridged, the amplifi-
er will deliver 1000 watts to an 8 ohm load. To
implement this configuration:
1. Turn the KAV-250a off.
2. Locate the red switch on the back of the
amplifier and slide it from the NORMAL
position to the BRIDGED position. The
numeral 2 will appear on the switch, when
the switch is in the BRIDGED position.
Connect the interconnect cable to the
BRIDGED input, either balanced via the
XLR connector or single-ended via the
RCA connector. Do not use both inputs
simultaneously. Connect the speaker
cables to the speaker terminals labeled
BRIDGED(-) and BRIDGED(+). The
lifier is now ready for bridged operation.
