3.5.4 Passive bi-amplification mode
A pair of A1.5 amplifiers, each with a single analog input board installed, can be used in passive bi-amplification mode. In such a
case, each amplifier board of each A1.5 feeds the speaker's drivers of a given frequency range. The main advantage of this
configuration is the possibility to set a different global feedback for the different frequency bands. The picture below shows how
the passive bi-amplification mode should be wired.
