My AD900 works with the switch pushed away from "normal"
Looks like the response from Godlyke above says most of it... the AD-9Pro does indeed draw 39mA under normal use, but when powering up (only the first half a second or so) it actually draws about 175mA. This is more than what the regular outputs (1-4, 7-8) on the PP2+ can provide, so it simply doesn't start up. Outputs 5 and 6 has 250mA available (still in normal/down/off mode - I'm not talking about the L6 mode), so it *should* work from one of those.
That's weird. I have my Hardwire DL-8 running off one of the normal outs of my PP2+, set at 9v (stock dip setting). No issues and it's had months of daily use. Even though you have the non '+' edition, that shouldn't make a difference.I'm having the same issue with my Hardwire DL-8! Refuses to work unless the dip switch is flipped...and I've played for probably 3-4 hours now, no problems.
I also have the PP2, not the +, FWIW.
Wait - you have the PP2 (not the PP2+)? That explains it - the older model (PP2, without the "+") has 100mA max for all 8 outputs in normal/down/off mode. With the "plus" model, they raised the max current on outputs 5 and 6 to 250mA, to accommodate the Boss Twin pedal series.That's just it though, it *doesn't* work when plugged into those unless the switch is in L6 mode. That's what is throwing me. I've tried it in every output and it only works when in that same mode. I looked for a owners manual online of the PP2 but could only find information of the updated version (pp2+) and I'm not sure if they're the same.
