MIC MODE JUMPER – P6
The MIC MODE JUMPER is located on the P6 jumper block and is used to optionally route the radio
microphone that is connected to the
RIGblaster pro on to the computer sound Mic In connection and to
either provide for bias in the case of electret microphones or no bias in the case of dynamic
microphones. The default (as shipped from the factory) is with this jumper set to disable Radio mic out
to computer mic in. There are three possible settings for this jumper as follows:
When the “mic” LED is on, your microphone is connected to both the radio and the computer.
Depending on the design of your microphone and the input impedance of the radio and computer inputs,
you may get a slight bass roll-off making your audio sharper and better for DXing. This is because
some microphones have a simple bass roll-off filter in the form of a series capacitor.
In the process mode or with the P6 jumper in the default position, this is NOT a consideration.
