Richard,
I'll leave the heavy technical stuff to someone who knows more about
it than the little that I do.
As I understand it, the ALC is a feedback circuit that is to prevent
you from over driving the finals. Over driving can cause
distortion, RFI, possible damage to the finals, and maybe even athlete's
foot.
Setting the mic gain properly will keep the ALC meter in the proper
range, and the ALC circuit will work as designed. The manual says to
speak into the mic and have the meter move up and down with your voice,
but not to exceed the ALC limit on the meter.
The processor is supposed to level out the highs and lows in your voice
and give your signal more punch. Again, it needs to be set properly, or
you will have problems. 10 db max on the input, and on the output, keep
the ALC meter within it's range, and not exceeding the limit on the
meter.
The mic gain, and proc out may seem to be similar, but are different
settings and independent of each other.
I did see someone on the 2000 list suggest that you set proc in and proc
out both at 100 and get a signal report. Obviously a joke, but not
much help.
Default settings are 50 in and 50 out and probably good for starters.
If distorted, back things down. A pair of eyes is helpful in getting
this set up.
BTW, did you solve the problem of the S-meter not reading the other day?
