An audio amplifier arrangement contains reproduction channels (R, L, C, SR) with corresponding channel outputs, to which a selectable number and/or assignment of different combinations of sound radiators can be connected in the form of loudspeakers (Lr, Ll) and/or external loudspeaker boxes (Br, Bl, Bc) to obtain different reproduction modes, and a signal processor which can be switched in such a way, that different audio signals (Vr', Vl', Vc, Vcr) are made available for the reproduction channels, to obtain the different reproduction modes. Connecting the corresponding external loudspeaker boxes to predetermined channel outputs requires a change in the reproduction mode, whereby the assignment of already connected sound radiators is changed, and/or the signal processor is switched. According to the invention, part of the channel outputs have first and second switching means (Sr, Sl, Sc), which automatically make the required change in the operating mode when external loudspeaker boxes are connected.
