Bridge Mode - CH A1.5 User Manual

3.5.2 Bridge mode

A pair of A1.5 amplifier, each equipped with a single analog input board can be used as a pair of high power monoblock amplifiers
with high voltage swing. This configuration should be used when low efficiency high impedance loudspeakers are used in large
rooms to achieve higher sound level than with a single stereo A1.5. This configuration also exhibits a better signal-to-noise ratio.
The picture below shows how the bridge mode should be wired.
