ABSTRACT:
A speaker system includes a left channel input and a right channel input for receiving left channel and right channel signals respectively, a left channel driver, a right channel driver, an (L-R) driver unit, and a (R-L) driver unit. The left channel driver is coupled to the left channel input, and the right channel driver is coupled to the right channel input. During a video mode of operation, the (L-R) driver unit and the (R-L) driver unit are each coupled to both the left channel input and the right channel input. The (L-R) driver unit and the (R-L) driver unit have structure arranged to passively differentially combine the signals on the inputs to provide (L-R) and (R-L) acoustic output signals respectively. Switching circuitry couples the (L-R) driver unit to both the left channel input and the right channel input during the video mode of operation and to only the left channel input during an audio mode of operation, and couples the (R-L) driver unit to both the left channel input and the right channel input during the video mode of operation and to only the right channel input during the audio mode of operation.
