Power Biamplification (Stereo, 2-channel)
Power biamplification uses the MAT feature of the KAV-250a to send the same music
signal to all amplifier channels using one balanced or single-ended input connection.
When the KAV-250a is reconfigured for MAT, one channel of the amplifier powers the
Ioudspeaker's high frequency end, and the other channel powers the Ioudspeaker's low
frequency end. This connection scenario is used only with loudspeakers that feature
two sets of binding posts. For more information, consult the owner's reference for your
loudspeakers. The diagram below illustrates connecting a system for power
biamplification:
