Is MENU:MIC SEL set to rP.H/FP.H or rP.L/FP.L? For a dynamic mic like the PR-10, you will want to select the High gain (xP.H) settings. If you are connecting to the front panel, you can also tap the "7" key to turn on an *additional* gain stage if necessary. See page 55 of the K3S Owner's Manual.

The specification sheets (on their web site) show the output level specifications for both the PR-10 and HM-12 at -55 dB. The microphones show similar bandwidth (80 - 14 KHz) with the HM-12 having a peak at 2 KHz and the PR-10 peak at 5 KHz). 73, ... Joe, W4TV On 11/25/2016 9:59 AM, Thomas Donohue wrote:
Hi to All: I’m using a PR-10 mic to drive the K3S; I find that I need to set the mic gain to 40+ to get sufficient output to push the ALC meter to nearly the top of its range. My XYL, W1JX, with a softer voice, needs to run the mic gain to the maximum setting (60) to achieve the same output. Other Heil mics such as the HM-12 only require a mic gain setting of 25 for both of us to achieve sufficient output.. I contacted Heil and was told that the PR-10 is much wider in audio bandwidth and therefore requires a higher mic gain settings; they further advised that my experience was normal. While I understand this, I’m just not comfortable running the mic gain setting at max to achieve normal output when my XYL is using the K3S. Am I missing something here? Any thoughts and/or advice would be appreciated.
