All (really ALL) DD-2, DD-3, DSD-2 and DSD-3 pedals require a PSA adapter.
An ACA adapter will damage them. |

Hi Laurie, what do you think 10 volts will do to a DD-3?
Here a local manufacturer offers a power supply for 4-8 effects claiming it to be ok for ibanez and boss pedals, nonetheless, his power supply outputs 10 volts which I find a bit risky for my long-chip DD-3.
The manufacturer says on his website that he decided on the ten volts after measuring different new 9 volts batteries which always provided almost ten volts.
I already saw people using his power supply supposedly with no harm on pedals. |

i'm not going to tell you everything will be fine using a 10v power supply, because i don't know. there seems to be some inconsistency between pedal power requirements and their power supplies...
i have Electro-Harmonix pedals which state they require a 9v power supply; the provided PSUs are actually rated at 9.6v... and the PSUs that came with my EHX pedals say 'Suitable for Boss and Ibanez' on the side.
i have DOD pedals which state they require 10v yet the DOD PSU is labelled as being 9v.

| I got a DOD FX 105 power supply to run my Vintage 1979 to 1988 pedals 10v and 15v both can be used at same time |

Used a roland acb 9v adapter on a mt-2, worked fine. When I used the same adapter on a mij dd-3 the dd-3 did nothing. Found out the acb adapter was pumping 14,4 v  Didn't damage the dd-3 though

The PSA adapter was introduced with the RV-2 and was the preferred adapter for all early digital pedals.
The easy rule to remember is
blue, pink, silver labels - PSA
black, green, orange labels - ACA

The DD-2, DD-3, DSD-2 and DSD-3 require the following:
- a regulated supply (unregulated/filtered is inadequate)
- a voltage that NEVER exceeds about 10V under any load condition
Using a supply that is higher than 11V will certainly, sooner or later, damage the pedal. The infamous "D6" failure will result.

| Thanks, Laurie. I've only used a battery on my DSD-2, but it proves you have to be careful. I use an 18v adapter on my AD-80 and it uses the same 1/8 inch plug that my old TS-808's have. Wouldn't want to accidently mix those up! ZAP!!! |

the most important voltage on the DSD is that super-fun 5v pulse input!  |

| I've run mine off an old DR-220A - the rimshot sound outputs the 5v pulse. I also have a nifty 5v pulse-box which allows me to trigger the sampler any time I want while keeping the knobs at finger-level! I can't remember if I ever plugged mine into an ACA.. hope not! |

Hi Bob Barcus,
Due to the reason that these pedals are consuming above 50mA so the voltage needs to be kept stable around 9V and it is only possible from a stabilized PSA adaptor and not from a simple ACA version. As I am using a daisy chain with 10 pedals and a PSA adaptor in my system is working very well even if some pedal in the chain still requires ACA individually!
Hope I could help a bit!
cheers |
