Connecting a Speaker or Subwoofer in Bridge Mode
Connecting a speaker or subwoofer in bridge mode increases the amount of power that can be delivered by
combining two output channels together. This is beneficial for large subwoofers that move large volumes of air
and for playing speakers louder without experiencing clipping in the audio.
NOTICE
A speaker connected in bridge mode must be capable of handling the increased output power. Bridge mode can
produce more than double the output power of a single channel.
You should connect only a 4 Ohm load to the bridged terminals on a zone. Connecting a 2 Ohm load to the
bridged terminals may cause damage to the amplifier, speaker, or subwoofer.
NOTE: When bridging the channels in a zone, you must use an RCA splitter to send the same signal to both the
left and right channels of the zone.
1 Connect speaker wire to the amplifier's positive terminal of the left channel for a zone .
2 Connect the other end of the speaker wire to the positive terminal on the speaker or subwoofer .
NOTE: The bridged terminals for a zone are connected with a line and labeled BRIDGED for easy
identification.
3 Connect speaker wire to the negative terminal of the right channel for a zone .
4 Connect the other end of the speaker wire to the negative terminal on the speaker or subwoofer .
5 Connect the split ends of an RCA splitter to the left RCA ports for both bridged zones on the amplifier .
6 Connect the single end of the RCA splitter to the left RCA stereo output .
7 Connect the split ends of an RCA splitter to the right RCA ports for both bridged zones on the amplifier .
8 Connect the single end of the RCA splitter to the right RCA stereo output .
9 Adjust the volume level and other settings for the zone (
Adjusting the Level for a Zone, page 13
).
