Yamaha DTXpress/DTXplorer/DTXtreme

Hi there,

Yes, email the guy straight away with any and all your questions and 
concerns.

Like said I suppose it could be a bad power supply. I'd think that 
it's rated well enough @ 3amps, but could be putting out less. Is 
the display well lit? Dim? If bright as star then maybe ok. But you 
could always go to Wall-Mart, K-Mart, Radio Shack & pick up a power 
supply or two (TODAY or the next). Maybe even one with switchable 
voltages & a set of multi-plugs. Try to get to the closest rating 
you can. I would prefer to have THE Yamaha one, just because.

I would also check with a 2nd pair of headphones, OR be SURE the 
phones are ok. Have you tried the stereo L/R OUTS on the back of the 
module yet with something? Check those! Maybe there IS a problem, 
but only the headphone outs? I'd think that the headphone outs would 
have their own output amp & the stereo L/R out should be line 
voltage, so I'd try the L/R stereo outs on those powered speakers 
you spoke of, or to an amp, stereo system, PA etc...
