Members The Friendly Ranger Posted May 13, 2006 Members Share Posted May 13, 2006 You're supposed to use a 9V supply. Some stompboxes are designed to accept higher voltage and step it down to 9V but whether or not the DD-20 can do this, I do not know. To me, it's just not worth it to find out the hard way. I'd use a 9V supply. Link to comment Share on other sites More sharing options...

I'd use a 9V supply. Word. I don't want to blow anything up, but I didn't have a 9v handy, so I thought I'd ask. I'll pick one up tomorrow. Weirdly, the DD-20 manual is pretty vague about what kind of power supply it accepts. It just says an AC supply, Boss PSA series. Also, now that I mention it, I'm not even entirely sure why I think my particular power supply is 18v. It's a Jim Dunlop one that I've been using with my 535q wah pedal. On the back, it says: I/P: 120V AC 60Hz 8WO/P: 18V DC 150mA Link to comment Share on other sites More sharing options...

Members phyrexia Posted May 13, 2006 Members Share Posted May 13, 2006 The PSA120 is the standard 9v adapter that Boss has used for a long time. I don't think they say in the manual what it is really. The DD20 is a current hog so make sure it has its own power supply or you have a big one (like a Powerall or a Onespot or what have you.)

Members State 6000 Posted May 13, 2006 Members Share Posted May 13, 2006 "The PSA adapter is a regulated power supply that outputs 9V DC and can supply up to 200mA current. Regulated means that the power supply contains a circuit that helps stabilise the voltage at 9V even when the load is increasing. The earlier ACA adapters did not have this feature and when many pedals were connected, the voltage would drop." www.bossarea.com Link to comment Share on other sites More sharing options...

Members The Friendly Ranger Posted May 13, 2006 Members Share Posted May 13, 2006 I use a Pedal Power 2 Plus myself. I'm not a big fan of wall warts and the PP2+ makes things nice and tidy. It's not cheap but if you consider how much batteries and wall warts cost it's probably the more economical solution in the long run. Link to comment Share on other sites More sharing options...

Members phyrexia Posted May 13, 2006 Members Share Posted May 13, 2006 I have a GodLyke Powerall (1.3 amps, i think) and ran everything on my board at once with it, no issues. Now I could run all my pedals with one boss adapter Link to comment Share on other sites More sharing options...

Really? I never had any issues with it. I guess YMMV. Link to comment Share on other sites More sharing options...

I've run my DD-20 off of both the PPII on the line 6 setting (16V i think) and with the powerall, with no noise or problems ever. Link to comment Share on other sites More sharing options...

If you turn on an iron all the lights dim. maybe i should make sure i'm not at the +4db setting.it could also be cables in front of the DD-20 inducing noise into the signal.

It sucked bigtime when I used high gain. I swtiched to the PP2 for that reason and it fixed it. Link to comment Share on other sites More sharing options...
Members veil Posted May 14, 2006 Author Members Share Posted May 14, 2006 Ok, I also have an Alesis 9V adaptor, but it says 830mA. I don't even know what mA is. Does it have to be 200mA to work/not kill my pedal? Link to comment Share on other sites More sharing options...

Does it have to be 200mA to work/not kill my pedal? it will be alright, the mA is what the power supply is capable of putting out. you will only draw 200 mA of the 830mA available, so you will be fine with power to spare. The DD20 takes 200mA. although 200 mA at 9V is less power than 180 mA at 18V, but I don't think putting 18V into the DD20 would be good. Link to comment Share on other sites More sharing options...
