Steve:
Well, that's the plan for now.
Do you have any thoughts on the best setting for the mic gain when using
the TS480 with the MC60 with the pre-amp in? Right now, I have it set at
50.
Also, do you have a recommendation for which TX equalization setting works
best with the MC60?
Thanks as always for your help.
