FLIGHTCOM SR4 EXPANSION MODULE FOR IISX

Our most inexpensive headset is The CrazedPilot CP-1, Part # 11-12918. Another good option is the ASA AirClassics HS-1A, Part # 13-18471.

The telephone cord pictured and included with this item connects from the IISX intercom to the expansion module. This allows for two more headsets to connect into the intercom.
