The SPA-4S is a compact 2 or 4 place voice activated intercom with inputs for stereo music. It is a compact system that allows it to fit in space critical panels. The SPA-4S uses the industry standard Sigtronics squelch, fast on slow off for hands free communication. The music will full mute during ATC communication and partial mute during intercom communication. When radio / intercom use is ended the music will gradually return to its previous volume.

The SPA-4S only requires 1” X 2.5” of panel space, mounts horizontal or vertically, is 4” deep, and weights 5.5 oz. The SPA-4S intercom can easily upgrade the SPA-400.
