John,
If you apply bias to a dynamic mic, the microphone element will be
pulled off center by the bias voltage. Much the same as putting a
voltage across a speaker.
It *could* damage the element is the element wire is not large enough to
handle the current, but with the mic element not in
If you use an electret with no bias you have no audio. What happens if
you use a dynamic mic with bias on such as the HC4/HC5 element in the
subject line?

Steve,
Here are the settings I use with various Heil elements.
I am currently using a Heil Proset K2/K3 with my desk K3 and a Elecraft
MH2 with my "portable" K3, but have used all these combinations with
success at one time or another.
Your mileage may vary.

"Rule of thumb" - if the microphone produces any audio at all with no
bias, it should be run with no bias - it is a dynamic type.
Electret elements will not produce any audio at all unless bias is
turned on.

Heil is giving out erroneous information. The low output Heil
microphones require setting the K3 mic gai
The HC4 and HC5 elements are low output dynamic types - no biasneeded.
In fact, it must be off.

I'd try Front Panel, HIGH, no bias assuming this is a dynamic
microphone. In general, Heil dynamic mic elements have low output levels.

Did you power the k3 off from the power button or by cutting power to the k3?
