I have the rat shack meter, but don't you need a microphone to run the automated room correction? You mean there is an output on the rat shack meter to use it as an external microphone? I guess from what you say there is... I remember seeing a little mini plug hole. I have to find that rat shack meter now... any reason not to use the Denon mic that came with an expensive receiver? Not sure why they wouldn't just throw in a microphone that they are familiar with...
