Yamaha DTXpress/DTXplorer/DTXtreme

Hi everyone, 

New to the e-drum world and to this board. I had some questions about 
my new Yamaha DTXtremeIIS kit.

I play in a band with guitarists who use really loud tube amps 
(vox/orange 2x12s). Last night we attempted live use of my new Yamaha 
DTXtremeIIS.

I'm playing through a PA in a fairly small basement room. The problem 
I'm having is that the volume of the amps are actually impeding the 
signal for the pads somehow (they seem to resonate through my tom 
pads the most - i discovered this by process of elimination) and 
sends a crappy sizzling signal through the PA. Also, when I play, I 
can tell that the signal and response of the kit starts to cut out. 

Any recommendations? Unfortunately, turning down the guitarists is 
not an option. 

Thanks.

I also own the great DTXTreme-2. I have my JBL set on stun, and my 
snare cuts out every second bar more or less. Cannot replicate the 
problem with headphones. No problems with toms or kick drum. 
Contacted Yamaha and they said to check patch cord, and pad. Since 
it works flawlessly through headphones, must be the module output to 
speaker, or JBL, or some weird thing between the pad speaker 
perhaps? Some suggest some type of pizeo feedback between speaker 
and amp. Anyone else having this type of problem. Sure places a damp 
towel on what is a module with awsome sounds and features. I have 
the reject and self reject settings as low as possable. Do not have 
cross triggering issues.
