Hello,

I have Audiosport headet RS60CF - M350 - electret microphone that I use on a Icom Ic-7610
I want to connect them with an additional adapter to the MIC-1 input of MB-1?
Since I don't have a schematic of how the bias is performed inside the MB-1 Mic-1 input, I'm considering whether to connect the tip and ring together to a 3.5mm stereo jack to give the microphone the power it needs.
Has anyone already done the same?


thank you!

If you look at the MB1 user manual section 2.6, you will see the pin wiring for MIC-1, including how the 2V bias is supplied. Does that help? My electret mod mic uses the 3.5mm stereo MIC-1 socket with nothing special needing doing.

Hello Erik,

Yes, I saw that ... That my microphone got powered I had to connect the tip and ring together.
In contact with the Dave WI6R handset manufacturer he advises me to use a cable CS6-YRJ-PTT-EM that terminates with an RJ45 connector and takes a Bias from a 9v pin .. What bothered me is that I have a 2.5k electret microphone and the Mic 2 requires an input for 500-600 ohm impedance...



Thank you!
