Bridged Mono
For systems with high power requirements, the amplifiers can be configured for single channel bridged mono operation. To bridge the
amplifier, set the rear panel MONO switch to the Mono (In) position. The Channel 1 input and level control is used and the Channel 2
level control must be set to its maximum gain position. The speaker is connected to the RED output binding posts.
When the amplifier is bridged the output is floating. Any speaker which requires a common ground from the amplifier output
cannot be used in this application.
Since a bridged amplifier shares the load between the two channels, each channel will effectively drive half of the load. For
bridged mono operation we recommend using an 8 Ohm load as the minimum impedance. Less than 8 Ohm operation in
bridge mode is outside the operating parameters for the P3100 and should not be done.
