Tired of radio silence? Listen to music or get the play-by-play of the big game with Sigtronics SPA-4S intercom. The same great aspects of Sigtronics original SPA-400 intercom, with the added capability of inputting stereo music. The SPA-4S automatically mutes the music during ATC communication and partially mutes during intercom communication.

• Radio Priority: ATC will only hear the crew member transmitting
• Pilot Fail Safe: Pilot will always hear the radio even if the intercom is off
• Works with all brands of General Aviation headsets
• Reversible face plate for vertical or horizontal mounting included
• Individual Mic Bias: each headset microphone uses separate input line for improved clarity
• Music input jack

Its compact size (just 2 1/2” x 1”) and light weight (4.5 oz.) make it fit easily into any panel. All installation hardware, including jack kit and pre-wired harness, is included.
