ABSTRACT:
A circuit system for selectively switching between main and remote loudspeakers includes a pair of input terminals for applying an input audio signal to the loudspeakers. A first selector switch contact is provided in series with the main loudspeakers. A second selector switch contact is provided in series with the remote loudspeakers. A current-dependent resistance element is provided in series with the remote loudspeakers to protect the remote loudspeakers from overdrive. The circuit system may also include a second current-dependent resistance element and a cooperating defeat switch contact as well as a resistor and associated load limiting switch contact all in series with the remote loudspeakers.
