Capewell XABH-9000 Helmet Tester

The XABH-9000 Helmet Tester is a hand-held, battery powered instrument for verifying the proper operation of aviation-type speakers and microphones, individually or as part of complete headsets. The unit tests helmet communications systems by simulating an intercom system for verifying proper operation by wearing the headset and speaking into the communications microphone. Includes a built-in microphone and a speaker for testing individual speakers and helmet microphones and allows trouble-shooting in the event normal loop-back testing fails. The internal microphone has automatic gain control so that it can be used up close or remotely (to pick up ambient noise).
