1. An audio amplifier for driving at least one speaker, the amplifier comprising:
a controller for amplifying at least one input signal to provide an amplified audio output signal,
wherein the controller is configured to operate the amplifier in at least two modes, comprising:
a first mode comprising a dedicated connection to the at least one speaker; and
a second mode comprising a direct physical connection with an additional audio amplifier and the dedicated connection to the at least one speaker; and
an interface switch coupled with the controller that enables a change between the first mode and the second mode, wherein the controller maintains the selection of the first mode or the second mode until a command is received via the interface switch.
