Headset Adapter Cable
AD-1 series cables are required for Heil boom microphone headset models including PROSET Elite, PROSET, the original and reintroduced PRO-MICRO series and BM-10 series headsets, and the legacy PROSET PLUS and QUIET PHONE. These cables support all of the Heil Sound Headsets that feature a 3.5 mm (1/8 in. miniature phone) connector for the microphone audio. Each has a female 1/4 in. mono dongle connector on a short wire for PTT keying foot switch or hand switch connection.
HSTA series Headset Adapter Cables were specially designed for the legacy Heil TRAVELER Headsets that were discontinued and are no longer available. Some of the presently available adapter cables feature an extra wire and connector to go to the transceiver external speaker connector, for those radios where receive audio is not provided on the microphone connector. On transceivers that support them, the special UP-DOWN buttons on the TRAVELER Headset cables are connected with these cables.
