First confirm that your Proset has something OTHER than 200 ohm
elements (VOM/DVM will measure it just FB). If the elements are
NOT 200 ohm, then call Heil and explain what rig you are using and
the problem of low audio levels ... I fixed two sets so far, of
interest is ONE set has 16 ohm elements, and the other had 400 (!)
ohms elements ... Both are 200 ohm now, and work well with the MPs.
Be careful swaping the elements ...!!! BTW, increasing the INTERNAL
headphone level adjustments on the MP made little difference here...
