Mic Bias

When using a rear panel headset requiring Bias, what is the state of Bias on
the Front Panel mic connector?

I have a PR-781 Microphone that doesn't require bias, and have it
disconnected from the front panel when using the rear bias'd mic and the RP
bias setting in the menu. Do I need to do this?

Re: Mic Bias

Harv,

If you have the Rear Panel bias set on, and the Front Panel bias set on,
all you have to do is change MIC SEL fron the front panel to the rear panel.

In other words, no problem.

No
Bias is independent as to front/rear connections.

I use my headset w/bias (CM500) on rear and my Heil HM12 dynamic mic on from without bias in front jack.
