Do you mean Bias on and +20 db amp?

Bob Needleman

What is the purpose of turning on the mic "bias"?  I can't find any info on that in the 6600 user's manual but may have missed it.   I know Elecraft uses the term for providing 'phantom power' to electret type mikes that require +7 VDC to power the element, but it doesn't seem like that corresponds to the 'bias/dB' feature in the Flex?

Hi Pat, The bias is just what you are describing - bias voltage for electret mics.  The +20 dB button turns on the mic preamp on and off, and is independent from the bias.

No need for BIAS if you use a Dynamic Mic like PR40 - maybe you can **** your dyn. Mic with BIAS !!
I am using the PR40

You may need the 20db gain enabled, Make sure you are close talking the mic to keep you voice consistent. Is you power meter set for AVG? that will help determine if you audio is were it needs to be.

Here is a screenshot of the Flex Manual for how to set up the audio input level for SSB.  Only add the +20Db gain if necessary.

Good picture Bret and pretty much what I described rolling off the bottom and increasing the highs because most of the Heil mics are bass heavy
