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 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.

Easy Upgrade
Each intercom comes complete with all necessary mounting hardware, jacks, and two 4-foot pre-wired harnesses. 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. The SPA-4S uses the same panel hole pattern and interface cable as the SPA-400. A second cable is provided for the music inputs and headphone outputs.

The FAA TSO approved SPA-4SN is available for the high noise amateur built aircraft and helicopters. As with all of Sigtronics’ products, the SPA-4S / SPA-4SN are RFI and EMI immune. The SPA-4S intercom is constructed of high quality components and carries a five-year parts and labor warranty. The SPA-4S will operate on an input power of 11 VDC through 32 VDC. Maximum current drain 0.10 Amps.
