ABSTRACT:
A solid-state sound effect generating system for selectively producing any one of a plurality of predetermined sound effects has a plurality of interchangeable plug-in printed circuit boards each having mounted thereon an electronic circuit capable of being actuated to produce an electrical output signal representative of a unique one of a group of desired sound effects, without the use of any prerecorded signals or recording medium. The circuit boards are plugged into a common control chassis which interconnects them with an audio power amplifier and loudspeaker arrangement and which further provides input terminals for external triggering signals.
