SPA-4S Two or Four Place

Compact Stereo System
The SPA-4S is a 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 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.
