Will Heil Pro 7 Headset work with Maestro C

Curt_AC9HO

I have been using a Heil Pro 7 headset with my Maestro B and now that I have received my Maestro C I cannot get it to work. Will this headset work and if so what do I need to make it work?

The Heil Pro with the 1/8" connectors should work in the Maestro C with the Y Cable adapter.

I have tried the Heil HMM hand mic with a 2to1 adapter for mic and speaker, the Heil BM-17 headset with a 2to1 adapter for mic and speaker, and Apple headphones with what I assume is the TRRS CTIA end on the headphones. What am I missing and why is this more difficult than it needs to be?? The only thing I can figure is the adapter I am using is not a TRRS CTIA adapter, and the Apple headphones are to old to be TRRS CTIA since the Maestro manual says that Apple headphones would work.

I did order the Y adapter and the FHM-3 hand mic today, but I have had my Maestro C for 3 days now and have yet to make a contact with it. Slightly frustrating, but everything else seems to work as expected.

Thanks Mike for the reply. I am just waiting for the Y cable adapter to come in the mail.

Well I have received my Y-cable adapter from Flex and the FHM-3 microphone. I plugged it all in and viola I made contacts. I then decided to try the Heil BM-17 headset and the Heil Pro 7 headset and unfortunately they do not work. I noticed that the plug for the mic on the FHM-3 has two black rings and all my Heil mics and headsets only have one for the mic cable. Is there some sort of adapter that I can get to make my Heil mics work??

I have the same issue, with the y adapter my FHM-3 works fine. I am also using old beats ear bud headphone/mic with a TRRS plugs, works great with good audio quality. If I try and use my Heil HHM or Pro Set elite (iC element) with the Y cable the mics dont work. Both Heil mics use a TS plug and the FHM is TRS, so assume a TS to TRS adapter must be needed. For the iC element looks like you have to turn on Bias in the mic setting. Does anyone know if the Maestro delivers enough voltage for the element or have a recommendation for the TS to TRS adapter, assuming thats what the issue is.

What about the Heil Media Pro, ment for sound cards. Will that work on the Maestro C or does one have to use sets designed for traditional radios, like the Pro 7?

I made a TS to TRS cable and plugged in the mic side of the y-cable and the Heil BM-17 dynamic works. I assume the Pro series will work or any mic with a TS. I do have to use more mic gain, even with the 20 db turned on, than when connected directly to the radio. On a side note, the audio from the Maestro is lower than getting the audio directly from the radio.

A quick method for Heil until Heil makes an adapter is to buy a 1/8" TRS Male to an 1/8" TS Mono splitter on Amazon. Plug the Mic in one or the other. One will work and cut the other side off.

There has been a discussion here about it already.
