de-emphasis per port.

They probably designed the audio stage to reject
sub-audible tones. The audio response is perfectly
adequate

Thanks for the research Kevin. This Cat 200 is a good one to start
with. I did not do the original install, so I will check the values.
Mr. Lightning as not been good to this site, so this is the 3rd
repeater the controller has been on.
Jim,
If the end-to-end audio pre-emphasis and de-emphasis is not complementary,
the audio will sound very bright, tinny, and noisy. Also, check to see if
the audio is getting pre-emphasized twice- that will really make it bright.

Put your MICOR speaker on the (mobile?) radio you are listening to, this
will give you an apples to apples comparison.
I use a MICOR speaker in my work truck, it's connected to a Kenwood 742,
and yes, it makes a BIG difference.

This may be out in left field, but I have built several repeaters using the
