The Digital Audio Recorder Adapter (EDMO# PA-80H/D) records everything heard over the helicopter intercom system to a digital recording device. It is excellent for creating aerial videos without excess cabin noise, and will record all of the audio transmitted through the intercom system, including in-cabin audio and ATC transmissions.This adapter works with devices that use a 3.5 mm stereo external mic input, such as the GoPro HERO2, Drift HD, or most other handheld video cameras or personal audio recorders. It can be used with a handheld digital audio recorder to create CVRs (Cockpit Voice Recorders) and is great for CFIs and students to review radio communication skills after the flight.
