FAQ
Is this one PTT for every radio?
No. Constant Able HA2 is built for this connector family only. Other radios need a different CA model — use DISCO Connect to match.
Will it work with my headset?
Headset side is standard U-174/U with auto dynamic/electret sensing. Swap headsets freely on the same PTT. European “Peltor wired” is handled by Constant Able.
Need dual radios?
Dual mono often needs two PTTs. Stereo platforms are a different path. Open Connect with dual-comm or email help@disco32.com.
