DHA AC Adapter Q

[LongHairFreak]

Hey TB

I want to plug my DHA MK3-VT1 into the AC aux outlet on the back of Voodoo Lab's PP2+. That AC outlet pushes out 200ma, but the AC adapter for my MK3/VT1 can have about 1200ma drawn from it. Does this mean the DHA adapter actually draws 1200ma? Which would mean that I could not use that adapter in that aux outlet?

Thanks

I'm sure Dave will be along to answer shortly, but my bet is that the draw of the DHA pedal is enough higher than 200 mA to be problematic for use with the PP2+, but that it's not drawing fully 1200 mA.

All my pedals have a DC power requirement not AC. If you plug AC into it then it's toast like most other pedals.

The MK3 draws about 200mA when operating but there is in rush current of about 500mA at switch on as the tube warms up. Davehallampsusa have suitable power supplies that will not only work but are very low noise, poorly regulated supplies will cause hum.

Ah Dave, the AC outlet he's talking about is a wall-type socket where one of your wall-warts would plug in. Not a direct connection to the pedal.

Yep. That's it. I'm just not fully understanding the use of the auxilliary AC outlet on the PP2+. This auxilliary outlet supplies 200ma to any pedal needing AC.

So, Dave. Is it safe to plug your adapter (which runs my MK3/VT1) into this auxilliary AC outlet?

Thanks...and sorry about the confusion my previous wording caused.

As long as the supply to the pedal is 12VDC not AC via the supplied adaptor then it should work. If it's 200mA at 110VAC than it will be fine.

Thanks very much for your replies Dave. But, oh man! I'm such a maroon!!
That auxiliary AC outlet is 200 'watts', not miliamps. My concerns were not at all valid.

You should be able to power the DHA from 1 of the first 6 slots on the PP2+. The dip switches on the bottom make the first 6 output 12VDC center negative if the switch associated with the output is away from the "normal" position. As long as the DHA is 2.1mm center neg you just use one of the black ended cords. I'd suggest using slot # 5 or 6 since they out 250mA instead of 100 like the others.

Pedal is centre positive, so won't work unless it can be reversed.

Voodoo Lab sells reverse polarity cables for the PP2.

Perhaps I'm wrong about this too, but it seems to me that the only slots that can be switched to 12v is 1-4. According to Voodoo Lab's site...
(slots 1-4?) 9/12V (x4) – Standard 9V and 12V Boss ACA
With each one of these four outputs delivering 100mA, you can easily power any 9V battery-operated pedals. Boss pedals that specify the PSA adapter operate at 9V like most other pedals. Boss pedals that require the ACA adapter operate at 12V which can be selected via switches underneath the Pedal Power 2 Plus. Any one of these outputs can be individually selected to run at 9V or 12V.

(slots 5&6?) 9V (x2) – High Current 9V and Line 6 Modelers
These two outputs each deliver 250mA allowing you run high current draw effects like the Boss DD-20 Giga Delay or Line 6 DL4 Delay Modeler. Via switches underneath the Pedal Power 2 Plus, these two outputs can be separately configured for regulated (Boss Twin Pedals) or unregulated (Line 6 Modelers) power allowing you to run both units if so desired. These outputs can also power any standard 9V effects as well.

(slots 7&8?) 9V (x2) – Standard 9V With Battery Sag Control
These outputs each have an available 100mA of power, but also allow you to SAG the voltage from roughly 4V to 9V. This feature can be enabled via the bottom panel switches. The SAG control is mostly useful for transistor-based fuzz, octavia, and distortion circuits, as most modern opamp designs are minimally affected by variations in supply voltage. We recommend turning SAG off if you’re going to run digital pedals like delay, chorus, and reverb.

So I thought I'd just use the proper DHA adapter in the PP2+ aux AC outlet. Of course, as has been noted, reverse polarity cables are available if I choose to do otherwise.

You are correct, only slots 1-4 can be switched to 12v; the dip switches on 5-6 switch between regulated and unregulated current.
