Yamaha CM500 Headset and Heil Adaptor

Recently purchased a Yamaha CM500 headset with a Heil AD-1-K headset adaptor
for Kenwood (the red one). I love the headset, much cheaper than the Heil
and performs about the same, IMHO.

The only way I managed to get the mic to work was through the rear jack
(yes, the mic was selected to front panel).

I did read in previous threads referring to mono and stereo mic connection.

Do I need to replace the stereo mic connector on the headset with a mono?

Is there a trick with the adaptor or am I messing up the set-up?

Are you using the BIAS box to connect it in the front?

Is a small black box with, I think, 2 x AAA batteries

Re: Yamaha CM500 Headset and Heil Adaptor

I am not. Do I need to, it seems very cumbersome to have it connected, plus
the batteries would go dead over time.

However, in the MENU, I have set:

rP.L bIAS

Bruce,

Unless Heil has changed the Kenwood adapter, it should work fine.
Test your adapter - put a bare stereo plug into the adapter and use your
DMM. Pin 1 should connect to the tip of the stereo plug. The shell of
the stereo plug should connect to either pin 7 or pin 8 (or both) and
the ring of the stereo plug should connect to either nothing or to pin 1
(but *not* connect to either pin 7 or pin 8).

If those tests are OK, it should work - set the Mic Sel menu to FPL.bias
and adjust the mic gain to indicate 5 to 7 bars on the ALC meter.

73,
Don W3FPR

Remove the adapter, plug in the headset to the rear connectors, select the
MAIN:MIC SEL menu, press [1], press [2] and you're almost done. (Mic rear panel,
Low Z, Bias On)

Now, you need to set the equalization. I get unsolicited good audio reports
with the following:

Band 1: -16
Band 2: -10
Band 3: -4
Band 4: 0
Band 5: 0
Band 6: 0
Band 7: 0
Band 8: -6

You will have to tailor this to your voice and preference.
