LOUDSPEAKER WITH SINGLE OR DUAL CHANNEL INPUT SELECTOR AND LOCKOUT

摘要

A dual purpose loudspeaker incorporating at least two audio signal inputs and at least one switch is adapted to receive and reproduce either a single audio signal input or two audio signal inputs according to the position of the switch. A switch slide mechanically linked to the switch is provided which blocks one of the audio signal inputs when the switch is in the single-channel position, thereby preventing erroneous connection to the blocked audio signal input.
