Actually, I had (have) this very same problem and brought it up on here quite some time ago. CM-500, mic and phones plugged into proper jacks on rear, preamp on, bias on, mic gain at max, mic right at my lips, and I still have to talk very loudly to get any response out of the ALC meter. I got another CM-500 and swapped it in, and it was better…I didn’t have to talk as loud, but still way louder than I’d like or should have to.
I never did puzzle out a solution for this. So if I need or want to get on SSB and can’t talk loud (say like if the XYL is trying to sleep in the next room), I put another mic on the front connector and have no problems getting plenty of response out of that, even if talking in a hushed voice. Oscar, if you find a solution to this, please be sure to post it on here…I’d like for this work…failing that I might try someday to find a different headset/mic combo... 73, Dave - N5DCH > On Jul 30, 2023, at 6:17 PM, Mike Dodd <m...@mdodd.com> wrote: > > On 7/30/2023 7:40 PM, Oscar Staudt wrote: >> When I got my K4D a month ago, I unplugged my Yamaha CM-500 mic and >> headphones from my K3, and plugged them into the back of my K4.
