Yamaha DTXpress/DTXplorer/DTXtreme

I am looking at using a pintech concertcast mesh head pad for a snare.
The question is.... is the pintech dual zone pad, stereo or a real 
dual zone? If dual zone I guess I would have to use the 9/10 input. I 
would like to know before I purchase I may decide to just get a 
single zone so I could at least have one more pad input for something 
else.
