I find it better to turn the hardware mike gain down, thus allowing one to
run the DSP Mic gain in the 35% to 55% range. Anything external such as an
attenuator is an invite for potential RFI in the audio issue. Also improves
S/N ratio in the audio stages.
Also in my earlier post I mentioned using a 6.8K resistor and a 0.1 cap to
block DC to the mike input to the radio. If there's too much signal from
the mike, increase the size of the resistor to 10K to 15K. Everything is
still the same physical size and will fit inside the 8 pin connector. I
agree with Jim, K9YC on the use of Switchcraft and Neutrik connectors.

Do NOT worry about excessive gain as long as you can turn down the mic

your signal quality from someone whose ears you trust.
If it ain't broke, don't fix it!

I agree. on my Omni VII, my Shure and Sennheiser
headsets were so hot, I had to turn the MIC GAIN
down to 2-3% and at that point the microphone was
either on or off, with little adjustment latitude,
and the AGC was on full blast full time.
As JB says, if it does not get that crowded on
your rig, with your headset, and you still have
latitude to adjust it, then you may not have quite
the same issue as I did. As he suggests - don't fix
more than the problems you actually have.
Just MY take.
