I was wondering if anyone here runs their DXMB at 12 volts. I just tried this today and it’s a night and day difference in the sound. The DXMB always ran too quiet for me, hard to distinguish the wet signal without turning the gain high. Running it at 12 volts though solves this completely. Adds a ton of volume to the wet signal. Also starts feeding back much sooner so I have to turn down the repeats quite a bit. The Vibrato and Chorus also are much more pronounced.

September 14, 2010 at 7:37 pm #111418czech-one-2ParticipantCOOL,I’ll try that also,but I’d like to hear from a moderator if there is any risk of messing something up first.
September 15, 2010 at 6:51 am #111430czech-one-2ParticipantWell, the manual states – The DXMB’s current requirement is 100ma @ 9v.,center negative polarity.The maximum allowable power supply voltage is 12v.
So there’s my answer!
September 15, 2010 at 8:24 pm #111436czech-one-2ParticipantWeird, I tried the 12v output from my BBE Supacharger AND a boss ACA 12v adapter.NO DELAY SIGNAL PRESENT.Works fine at 9v,but at 12v it powers up and flashes in tempo,but there is no delayed signal.And I tried 2 power supplies.So this leads me to beleive that
A] Its a bad idea
B] Its only my particular unit that hates 12vCan others please try this and post thier results?
By the way, this pedal is amazing! It booted my analogman high cut/expression pedal Boss DD-5 off my board,and thats saying something. Thanx EH !
September 26, 2010 at 5:03 pm #111673lasikukkoMemberWith 12.17 vdc no delay signal present but all lights work and dry signal comes through. 11 vdc Delay signal came back
and is stronger than w/original psu, controls are more sensitive too. I liked the delay sound more with higher voltage, slapback delay was not so dull and more percussive and longer delays blended better to the clean sound. Voltages are from different supplies, I will test with an adjustable one and post results here.September 26, 2010 at 10:02 pm #111678czech-one-2ParticipantThanks,glad to know its not just my unit!
February 15, 2011 at 7:29 pm #114329sirGalahad78Member@plaguex1 Which Voodoo Lab are you successfully running the DMB from at 12V? Or anyone else that has had success with this? I tried last night–flipping the jumper on outputs 1-4 on a PP2+ doesn’t work, as it yields 12.3V regulated which, as another poster already said, is too much and disables the effect. Unit powers up, but you get dry signal only and no wet. I don’t have as much experience with outputs 5-6, but according to the manual when the jumper is flipped, it’s 14.5V / 12V (unregulated) 50mA / 200mA+. I’m nervous to try the DMB on those outputs without more info. Anyway, I’m anxious to try this out but need a bit of help!
*UPDATE*
Just got off the phone with Voodoo Lab support (which rocked, btw… super helpful). He looked up the current draw on the DMB and confirmed that it would NOT work on a jumpered output 1-4 at 12V because it’s not getting quite enough current. It’s possible other things could be going on with regard to how the DMB responds to voltages slightly over 12, but he said I’d have to find out about that from EHX. But running outputs 1-4 at 12V definitely wouldn’t supply enough current. He suspected it would work on TWO of those outputs with a current doubling cable, or *maybe* outputs 5 or 6 jumpered, but again, before recommending that he said I should find out from EHX how the DMB responds to the possibility of slightly more than 12V since it’s unregulated on those outputs and you wouldn’t want to risk damaging it.So I needed some voltage doubler cables from Voodoo Lab anyway, so I had him toss in a current doubling cable just to have one. We’ll see what happens. Oh and unless someone responds here, I’ll see if I can hunt down info from EHX about the 12V+ issue.
