The MM-1 outputs line level. The DVX100 probably does not accept line level. You will need an attenuating cord (Sound Devices sells them) to drop the level.

You see? This is why I love the DVinfo forums so much! Here I am, thinking I'm all set to go out and get a bunch of equipment, and I would have ended up trying to put a square peg in a round hole. You guys rock!

Seriously, thanks for the heads-up, Jeff. I'll have to get an attenuating cord to plug the MM-1 to the DVX100. Looking at the info on their website, I'm not sure which one to choose from. Any suggestions?

Also, would I need an attenuating cord if I were to use a wireless configuration as described above? Or does that become unnecessary with a wireless system attached?

Thanks again!

It depends on the wireless system your thinking of using. Many transmitters will accept line in.
