Active bi-amp mode
3.4.6 Chained mode
When more than one A1 is to be used to drive a single speaker, they can be chained. This allows for ultimate configuration taking
both advantage of the increased power available in bridged mode, and the flexibility provided by multi-amplification (optimal
feedback ratio setting for each frequency band). The picture below shows an example of such a chained configuration, namely a
passive bi-amp bridged mode.
