Microphone transferability 6500/6700 to 6400/6600?

I have a desk microphone that was wired and worked well on a 6500/6700 using the front 8 pin foster connector.  Today I tried this same microphone on a 6600(M) supplied with the 8 pin foster pig tail to allow it to be connected via the PTT and MIC ports on the back.

The only way I can get some output (not very much) is to enable the 20db boast and turn the mic gain up to 100.  What is causing a mic that works perfectly on the 6500/6700 to not work in a useable manner on the 6600M?

FHM-2 mic?  And if so do you have the BIAS turned on?

Rich, I am not sure why you are asking about the FHM-2.  The FHM-2 mic works fine with the 6600M and it does require the bias voltage to be supplied.  My question is regarding a desk microphone that works good on the 6500/6700 but not on the 6600M when used with the Flex supplied foster pig tail adapter.

Sorry, John, I misread the first part of your post.

Good question. you would think think with Flex adapter it should work the same.

Sounds like a faulty supplied foster pig tail adapter to me

If you have an ohm meter, it should be easy to ohm out the connector.  The 8-pin foster connector pinouts are in the FLEX-6000 hardware manual.  If the mic in question is a condenser mic that requires a +5 VDC bias voltage, it may have the be rewired so the bias voltage pin on the 8-pin connector is connected to MIC+
