Shure, PSC, Wendt, Sound Devices are a few brands to consider at various price points. How many mics do you plan to have in use at a given time and is the feed from the soundboard mono or stereo? That'll determine how many channels you need to be looking at.

You can reduce the level from the board, but the issue is that you will be so far down on the slider, that you will loose any real adjustment travel on the slider.

It seems that the XLR to miniplug attenuating adapter is designed to send line and mic levels to the camera. why else would it have separate line/mic switches for each source? this leads me to believe that the limitation resides in the camera not the XLR to miniplug attenuating adapter.
