Overview

Measuring only 1" x 2-1/2" x 4" deep, only 4.5 oz, the SPA-400 and 6-place SPA-600 are FAA Tso'd and can be mounted either horizontally or vertically. Also available in special "HIGH -NOISE" model SPA-400N for Ultra-lights, and open cockpit aircraft, kit aircraft and warbirds. These intercoms allow you to put "push-to-intercom" buttons in the aircraft to eliminate VOX mode when desired.

This is especially good for open-cockpits where wind noise can be a problem. The SPA-400N simulates side-tone because some radios that are currently used in these markets do not have it. The SAS-440 and SAS-640 intercoms feature Sigtronics' exclusive "Auto-Squelch". One touch of the squelch button and the intercom perfectly sets the squelch level to your headsets and the aircraft noise level. All Sigtronics intercoms are voice activated with a 5-year warranty and operate on any voltage from 12V to 24V. Made in USA.
