Audio compression uses positive peak compression; not negative peak compression. If too much compression is applied to a limited audio bandwidth (like 3kc's wide), of course it will sound >squished< or 'mushy'. Sure sign of too much compression; but it is the threshold that starts too early that causes that.

IIRC, the AM Limiter is actually a positive peak limiter type of compression, which means that once the gain reaches a certain threshold compression takes place at a 4:1 ratio. I've been trying to find out how to change the upper threshold of limiting by finding out which part to affect in the AM Limiter circuit. Perhaps Shockwave can figure it out.

Some Turner mics have an adjustable compression threshold. Others have it fixed.
