So I borrowed one of these last night. Total garbage. For starters, the plug does not stay seated securely into the MT. It goes into the 1/8 inch input well enough, but any minor bump of the pad causes it to pop out halfway, almost as if it was spring loaded.
Secondly, I could not get it to pass signal from both AT853 mics, only the left channel. I pulled the pad and plugged the mics in directly and everything worked fine, so it must be the pad causing the problems.
I'm not sure if it is the way the thing is designed or if it is because the pad doesn't sit securely, but either way, it wasn't working.
Thanks for nothing, M-Audio.
