My CM-500 is about 4 years old, and shedding ear-pads, but it works fine
with my K3.

I had never used my CM-500 on a K3 so I can't do that comparison. But
on the K4 I had to turn on the internal mic preamp and set the mic
gain all the way to maximum. That seemed to give about the correct
level - I could talk at normal loudness to get 5 on the ALC.
I also use the CM-500 on my laptop to record a radio show. I had to
turn up the gain close to max on the computer as well. I think
late-production CM-500s just tend to have low microphone sensitivity.

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. I set
the
mic input to rear, and mic bias on. I expected the mic to perform
like it had in the K3.
I attempted to get 3-5 bars of ALC by turning up the mic gain
control. Even
with the gain up to 80, I’d have to speak *very* loudly to just get a
flicker on the ALC meter.
I then went back into the mic configuration and turned on the preamp
(14dB).
After that I could get some ALC bars with the mic gain around 65 or
more. But
I still had to talk much louder than I had to with the same mic on
the K3.
(note: mic level on the K3 was set around 7).
Question: Is it reasonable to expect that I’d have to have the mic
gain at
such a high level - and still have to talk louder than my normal (K3)
level?
BTW, I can hook up the MH-4, switch to front mic, and all works
smooth with
mic gain around 12.
