Yes, there is a hardware mike gain adjustment, R72, located on the Logic
Board. If one finds that the DSP mike gain is not satisfactory, thus one
requires more or less mike gain, then adjustment of R72 is required.
I would comment that the mike requirements for the Jupiter is 5 mV or -67dB.
If the mike of choice does not meet these requirements then a different mike
should be used. I do not see the need to use an external pre amp or
equalizer with the radio and a proper mike.

I've never needed a preamp with a dynamic mic into a Ten Tec rig. Last one
I owned was an Omni-V, and I used a low-Z pro dynamic mic with it going
straight into the mic jack. I'd be surprised if that's changed. K4TAX has
noted that some Ten Tec rigs have a trim pot to set mic gain that you
access through a hole in the side.
I'm sure he'll chime in to help.
