Re: [DTXpress] Power Supply - BS of D

2010-02-16 by S-E-A

Hi Dustin.
Not recommended!!!!

The voltage is ok, but the polarity is reversed, Roland's have the centre pin as -ve. The Yammy has centre pin +ve.
As the current the Roland PSU can deliver is quite high, any protection within the DTXpress module may soon fail.
Blue smoke of death..

Get a 'wall wart' or 'brick on a lead' adapter..
12V 800mA output. Make sure it is regulated!!
Make sure you get the polarity correct.

Ok guys, here's another question for ya; My DTXpress that I ordered doesn't come with a power supply but I have this big ass power supply from my Roland TD-7 that is: AC Adaptor IN: AC120V~60Hz 23W OUT: AC12V~1500mA. Can I use this? Thanks for helping this electronic idiot NOT fry his new brain!
