8400 Microphone requirements

Doug

The document says to use a dynamic microphone. Does that mean any dynamic microphone? Anything special I need to be aware of?

Hi Doug, the Flex 6000, 8000 and Aurora series will all accept dynamic or electret mics. The thing to be aware of is the pinouts of the mic connector and any power requirements for electret (condenser) mics. Be sure to create your own Mic Profile for each mic that you use with your Flex. That way the defaults won't overwrite what you have whenever you upgrade.

Mics that take "phantom" power will normally need a separate supply (typically high-end studio mics). Electret mics designed for use with computers can normally be used with the bias voltage supplied by the FLex.

For my desk mic, I use a Heil HM-12. It is a dynamic mic with a balanced output. I have a Flex cable that takes that and turns it into pseudo-balanced for my 6400. It also works the same with my 8600.

I also have a Yamaha CM-500 headset with an electret mic I built a simple adapter into a 3.5 mm plug housing.

Here is how I did it:
