I purchased a Heil PR20 microphone after comparing sound quality with several other options. To my ear, it had a nice combination of clarity and fullness. However, I am getting relatively low output from the mic and consequently low drive to the K3/100. With the microphone configuration on "hi" and with gain advanced fully (60), I have to speak fairly loudly to drive the K3 to 60 watts measured on an LP100 wattmeter. Power output on CW is the full 100w plus a little. I could design a small pre-amp stage to boost the gain, but am wondering if I am overlooking something (or is it common to use a pre-amp for this type of mic?)
