ES USAMO power led doesn't turn on

Post by GZHN89 » Wed Jan 08, 2020 7:21 am

I just picked up the Expert Sleepers USAMO at the postal office during my work lunchbreak and I also went to an electronic store to pick up an 9v 1000Mah power supply. After my lunch break I went back to my office and plugged it in to check if it would turn on but the power led doesn't light up... Does this mean that the unit is broken?? Or do I have to plug in a midi cable and audio cable before the unit turns on??? This sucks big time, I have waited for months before the unit was finally on stock. And now I have the unit, I cannot order a new one because they are again out of stock everywhere here in NL

The power LED should light immediately.

Can you confirm you got a DC PSU, not an AC one?

Yes it's an DC adapter. just the standard AC / DC adapter like the ones that are also used to power synths/pedals etc.

Does it have the correct 2.1mm barrel?

Yes, I got different barrel tips included with the PSU, tried the 2.1mm and another that fitted, also with both polarity options... nothing seems to be working.

Seems like either the PSU or the USAMO is faulty then.
