Okay, I'm back at it - have been successfully using a Mic 1 Level of 35 with my Bose A20 headset - this works really well. But I just picked up a Lightspeed Zulu.2 and I have too much noise when I transmit at high power settings. Since the Lightspeed has adjustable mike sensitivity I'd like to cut that back to match the Bose instead of further adjusting the SL40. Does anyone have experience adjusting the Lightspeed mike sensitivity? Is there a systematic way to do it?
