Mic settings via Acc input 6400

in FLEX-6000 Signature Series

I am trying to use the acc for use as a mic input. The signal chain is: dynamic mic to mic pre. Pre to acc 15 pin port via a trs to bnc cable, bnc to 15 pin connector.

On the radio I set the mic button to acc, and select the +acc button to on (blue)

When keying via foot switch, and setting gain via outboard pre, I do not seem to get modulation on the scope. Mic gain and proc do not seem to work. I assume I am adjusting gain and compression outboard. I do hear audio via monitor.

some guidance in mic set up via acc would be appreciated.


cheers all

Brad

    As I understand the use of the "ACC" mic via the 15pin connector:

    • If the +ACC button is enabled, the ACC audio source will be added to the selected BAL audio or MIC audio (i.e. for a voice keyer plus your regular selected microphone source)
    • if you Select ACC as the microphone source, that will be the single audio input.

    I think I found the answers I am looking for in the hardware reference manual.

    Any news on this? What is the pin out for line in? I see pin 1 is line in, but what is ground and do you use tip and sleeve?
