K3 Mic input rear panel

PeteWK8S
What is the pinout for K3 rear panel mic  input? Looking for how to wire a mic.  Didn't see it in the manual.
Off-the-shelf mic does seem to work even with K3 set to use rear panel mic.

Re: K3 Mic input rear panel

Cady, Fred
Hello Pete,
The rear panel mic jack is a stereo (T-R-S) jack with the mono mic signal on the tip. The ring is not connected. It is an unbalanced input and accepts balanced or unbalanced dynamic mics but only unbalanced electret condenser mics. When RL.X bias is on, it supplies 8 volts.
You can glean most of this by perusing the schematics. You can also see a summary of all the KIO3 connections in the chapter 7 sampler for the KE7X K3 book. Have a look at www.ke7x.com.
Cheers and 73,
Fred KE7X
