Description

SPA-4S Two or Four Place Stereo Intercoms

  • FAA TSO approved.
  • Pilot fail safe feature allows pilot to always hear radios.
  • Use Satellite Radio, MP3 or CD players as audio source.
  • Reversible face plate included for vertical or horizontal mounting.
  • Radio priority assures that ATC hears only the crew member transmitting.
  • Installation hardware included, including jack kit and pre-wired harness.
  • WARRANTY: Five years parts and labor.

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.

High Noise Environment N Series
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.
