I don't know about the Pro-set 6, but I believe the PR-781 has an XLR connector. If you want to connect it to the rear balanced input, just use a standard XLR female to XLR male mike cable. Alternately, you can use a balanced XLR Female to 1/4 inch TRS (Standard 1/4" stereo headphone type) connector. The rear balanced connector is a dual-type connector that accepts both XLR and 1/4" TRS. Nice!

I recommend the XLR input on the rear if you have, or can get, a standard balanced XLR cable. I am using the 1/4" TRS because I already had one made up for another rig.

The front mic (8 pin) input is wired like the standard Yaesu connector.

I'm using a Heil 781 into the XLR on the back. Just plug it in and select Balanced. The audio is superb.

Ken's description of the XLR cable for the 781 is correct.

I suggest you simply buy a ready made cable. They aren't expensive. If you want the details see the Wikipedia entry for XLR connector. It provides the information for each pin and even shows the XLR/phone connector used on the 6700. http://en.wikipedia.org/wiki/XLR_conn...

Thanks for the leads. I am trying to connect a Heil Goldline (XLR 4) to the Flex6700 Balanced Audio using the XLR 3 jack. I searched the internet for a premade cable but didn't find one (until yesterday via DXEngineering) but by that time I had purchased the parts (about 1/2 the price of the premade cable).

I am attaching a diagram of what I am doing. Even though I think I have the answer to the pin out question, I have to say that I am not 100% confident -- there are a lot of contradicting information on the pin outs on both the XLR4 & 3. I hope I have it right.

Bill,

That looks correct to me.

I have the connectors and cable to make up this cable to connect my Heil Goldline to my 6700. What I haven't figured out is should I connect the XLR connector shells to the shield, both ends, only one end (which one?) or neither end?

I use a Heil CC-1-XLR-Y-BAL adapter (and foot switch) for my EV RE-27 Mic, connected to the 8-pin mic input on the front of my 6700.  Works great.  What steered me in this direction was a post I read in another forum...

"I was confused by what cable to buy for my mic. I sent an email to Flex and within one hour I had replies from Tim Ellison and Matt Youngblood both advising me to get the CC-1-XLR-Y-BAL because the 6300 mic connector is "Pseudo balanced and provides better RFI immunity".
