SIGTRONICS SPA-4S STEREO INTERCOM FAA TSO
MFR Model# SPA-4S
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.
Each intercom comes complete with all necessary mounting hardware, jacks, and two 4-foot pre-wired harnesses.
