Pete, I'm using a CM500 that is a year or so old. It replaced one that finally fell apart and I was tired of gluing it back together. When I replaced the headset, I did not need to make any adjustments!
I went from a K3 to a K4 with the Yamaha headset plugged into the rear connectors. My Mic gain on the K4 is set at 12. TX rear mic configuration is Bias ON Preamp OFF. 73 George AI4VZ On Mon, Jul 31, 2023 at 9:32 AM Pete Smith N4ZR <pete.n...@gmail.com> wrote: > My CM-500 is about 4 years old, and shedding ear-pads, but it works fine > with my K3. > > 73, Pete N4ZR > > On 7/31/2023 6:52 AM, Alan Bloom wrote: > > I had never used my CM-500 on a K3 so I can't do that comparison.
