Compatibility Note

DISCUS pairing: DISCUS requires a dynamic (low-impedance) microphone. You can run DISCUS in-line with Constant Able when the headset mic is dynamic. If your headset uses an electret or amplified boom mic, use Constant Able alone — DISCUS will not drive those mics.

If the downlead on your headset has red rings, you will require the TP-105 O-ring as an addition to this PTT. Red rings typically indicate the U-384 (Dual Comm Split Audio*) configuration.
