Abstract
An audio amplifier circuit that is to receive three audio channel signals as inputs. A first amplifier has a first pair of outputs one of which produces a first combination sum of the three audio channel signals, and the other produces a second, different combination sum of the three audio channel signals. A second amplifier has a second pair of outputs one of which produces a third, different combination sum of the three audio channel signals and the other produces a fourth, different combination sum of the three audio channel signals. Other embodiments are also described and claimed.
