What is Microphone Bias Voltage? - Learning about …
http://www.learningaboutelectronics.com/Articles/What-is-microphone-bias-voltage
Microphone bias is a voltage used to power the Junction Field Effect Transistor (JFET) often integrated into an electret condenser microphone capsule. JFETs present the electret conderser with a relatively high input impedance. This reduces signal loss and helps present a low source impedance to the microphone preamp.

There are two sources for Bias on the 8-pin Foster connector: There is an always on 5V sourced through a 560 Ohm resistor to pin-2 as shown below. You can also turn on the Mic Bias in the GUI that turns on a 2.97V source that is applied to pin-8, which is the microphone hot lead.

FP means the front panel 8 pin mic connector. Bias is ON for an electret mic element but the Heil model you have uses dynamic elements so it is off. There are two elements in the mic, are you getting similar results with each? if so, maybe you need to double check the wiring to the mic connector.
