wrapping my mind around pedal power

[Hellion]

trying to ditch my 2 cheap-ass EQ pedals by adding the HX stomp to my board in 4CM. maybe I just need to write all this out to think clearly, but I'm trying to figure out if I need a new power supply in order to add my HX stomp to my pedalboard. being a high current pedal, I'm worried it won't work with my current power supply.

here's a list of what I'll have on the board and the power specs if i can find them:
-Ibanez wah 9V / 41mA
-StageRight/Monoprice tuner 9V / ???mA (just a tuner so probably not a lot?)
-Boss SD-1 9V / 4mA
-HX Stomp 9V / 1000mA (apparently uses around 1A but capacity is 3A)

This is the pedal power supply I'm already using: the ISO-5 model https://www.amazon.com/Voodoo-Lab-Pe...dp/B003H91JDS/
At first thought, my initial setup would be:
9V 1 Wah
9V 2 Tuner
9V 3 SD-1 overdrive

9V 400mA ↓
12V 400mA Y split cable from both outputs to run into the HX Stomp

18V nothing for now

will the 12V cause problems? will the 9VmA and 12V 400mA combine to make 800mA and would that even be enough power? I have a 3 output daisy chain cable and tried plugging that into the 3rd 9V and the high current 9V and 12V but when I connected it to the HX stomp it wouldn't turn on. maybe a daisy chain cable is wired differently than a power doubling cable? see this is where I'm getting confused whats the easy solution here? can I get by with just a proper power doubling cable? https://www.sweetwater.com/store/det...-str-y-doubler doubler cable

heres what I'm looking at replacing the power supply with if thats the route I need to go:
https://www.sweetwater.com/store/det...l-power-supply onespot pro CS7
https://www.sweetwater.com/store/det...l-power-supply Strymon Ojai or maybe the lopro model

Doesn’t the Voodoo Labs have a plug on one side too? If so you could plug the HX stomp into that with its dedicated power supply, that seems like the easiest route IMO.

huh, like a wall outlet passthrough? I know mine doesn't have that feature but that would totally solve my problem

[metalheadpunk]

Ahh yeah I’m thinking of the bigger Voodoo Labs power supply.

[Hellion]

dude i should have checked out your music sooner. this shit fucking rips.

[metalheadpunk]

Thanks! Appreciate it

As far as pedal power goes, I think you're gonna need to grab a bigger supply to make what you have work with the stomp. Some guys on the Line6 forum mention that the CS7 should do the job, FWIW!

The current ratings are really just upper-limits. Like, if you have 4 ports and 3 are listed "100ma" and the other "500ma" then the total capacity is 800ma. You could run 4 pedals, each pulling up to 200ma and be fine (generally). You could run 4 pedals that pull 35ma (like an overdrive) and be fine. You could daisy-chain up 10 pedals in any config, and provided that, combined, they're not pulling more than that 800ma rating for the supply, you'll be fine.

Voltage ratings are much more specific, and should be matched as close as possible as to not damage a pedal. Sometimes you can go under and "starve" a pedal and be fine, but I'm not sure that applies to some newer digital pedals. I have the TrueTone CS12 thing, and it's got a pair of those where you can run lower voltages than 9v, but I've never used that function. I actually put all my pedals in an excel sheet and calculated the total amp draw, because like most, mine has some ports listed as 100ma, 200ma, and some 500ma.

TL;DR, as long as the total current draw of all your pedals isn't higher than what the supply is rated for, you'll be fine. Don't go over on your voltages

so then this 400mA is probably shared between the 9V and the 12V outlets here?


even if they weren't I'd be going over 9V trying to use that 12V. Thanks. I think I understand this stuff a bit better after your post. I think I'm gonna give the CS7 a try.

[Leon]

mmmmmProbably? Really, unless you're running a bunch of Strymon Volantes you probably won't go over the current capacity

If I were engineering that, I would give suggestions for each port, and an overall rating for the whole unit. That graphic design choice makes it confusing. I read it as, "9V and 12V, both supplying up to 400ma," but your interpretation is just as valid.

[Jeff]

For the HX Stomp, you need two 500ma 9v ports, combined with a Y for 2.5 center negative. If you use 12v, you’ll fuck it up. You need a different power supply, I’m afraid. True Tone CS6, CS12, Strymon Zuma, Voodoolab PedalPower 3 will all work.

just ordered the Truetone One Spot Pro CS7

now to stare at the shipping updates while I fumble through exercises.

Yeah so the two 500ma, and then you’ll need either a few conversion cables, or there’s a new cable specifically for the HX Stomp/XL/HX Effects that VoodooLab is making, that I’d recommend.

I found this and ordered it along with the new power supply. the old one came with a cable that has the 2.5mm jack on one end(for the HX stomp) and the normal 2.1mm on the other. I think I should be good to go.

Just make sure what you’re connecting to that isn’t center positive, or you’ll potentially fry the Stomp.

I have a HX stomp on a pedalboard and use a CS6.

I used the same cable as you here, but you cant just use the 2.5mm converter with it, as that is reverse polarity and you will fry your HX stomp. You have to use the voodoo labs cable to double the current, then use the standard 2.1mm reverse polarity converter, and then use the 2.1mm-2.5mm converter with is also reverse polarity. So essentially you are reversing the polarity, and then reversing it back to centre negative with the 2.5mm converter.

As Jeff said, do not use the 12v outlet. Only 9v 500mA outlets.

[metalheadpunk]

From what I understand the CS6 will direct as much power as needed to each port, you do not need the splitter cable. Lots of info on powering the HX Stomp from the CS6/7/12 on the Line6 forum and TGP fwiw

Ah that’s interesting to know. I’m using it now anyway so I’ll leave it as it is, but I’ll keep in mind if I need to free up some ports.

this is whats on the voodoo labs page for what came with my ISO-5. are you sure that red cable is gonna reverse the polarity? thats the cable i mentioned using along with that power doubler. I can't find anything saying that it reverses the polarity. The red cable for the CS7 does say so though. I was gonna use this voodoo labs cable to go from 2.5mm down to 2.1mm then connect that to the doubler. then go into two of the 500mA 9V ports on the CS7. maybe I should just stick with the CS7 cables and do all the polarity bouncing? I thought the voodoo cable was gonna save me that step.
your little board there is totally awesome btw!

I used the voodoo labs current doubler like you have bought. I then used the cables that came with my Truetone CS6, I'd stick with the cables that come with your CS7, at least you know they will definitely work.

CS7 showed up a few days ago and the power doubler cable arrived today finally. I did try the old voodoo labs cable just to see what would happen but when it wouldn't power on right away I figured it wasn't a good idea to keep trying it. the voodoo labs power doubler and the CS7 cables for the 2.5mm jack and polarity reverse worked a charm though. It'll go on the board sometime tomorrow afternoon.

Hell yeah! Glad you got it working

It's handy having a multimeter for times like that!
