3.5.5 Active bi-amplification mode

A pair of A1.5 amplifiers, each with two analog input boards installed, can be used in active bi-amplification mode. In such a case,
each output board of each A1.5 feeds the speaker's drivers of a given frequency range. This configuration is optimal when an
active crossover network is used. Optimal global feedback can be set for the different frequency bands. The picture below shows
how the active bi-amplification mode should be wired.
