Yamaha DTXpress/DTXplorer/DTXtreme

My bookmark for Giles' site with all the tips for dtxpress doesn't 
seem to work.  Is there a new address or is the site gone?

Also, I am playing live this week with a club's board and PA instead 
of my church's PA and am concerned about my dtxpress mix and eq-ing.  
At church I go direct to the board where we have saved eq settings 
for my kit.  Since I am playing somewhere else, should I get a cheap 
mixer to use between my kit and the house system?
Thanks.
Bill
