AA31-306 ICS Mode Controller | NVIS B

The AA31 ICS Mode Controller provides a convenient, centralized method of organizing the aircraft audio system into multiple intercom circuits for independent or common operation. This function is especially valuable for EMS and law enforcement applications, where several independent operations occur within the aircraft that often require isolation from each other, while retaining the ability to share common communication. The AA31 can provide ICS switching for three or four Audio Controllers, or other products incorporating an ICS TIE LINE. The AA31 also has provisions for driving external annunciators and interfacing for ICS Calling.

Version (EDMO# AA31-306) has NVIS B lighting.
