@Stephen Docherty Some pedals can indeed take up to 18v with no issue. Another option is to use a port splitter to power two pedals from a single port. This make the two pedals non-isolated from one another, but isn't always a big deal. Brian Wampler has a good video on this: kzbin.info/www/bejne/jGrNeHqFo6p9fbs

I’m curious about the seemingly cheaper power box. Some people on the internet are saying the power supply I bought isn’t isolated. I’m going to do the test with my multimeter. I bought a vangoa pedal board with integrated power supply and it says that it has an isolated power supply but the power cord for the wall outlet is a 1.5 amp power supply. I’m wondering if I was tricked into believing I bought isolated power in the board when they meant it comes with an isolated power converter as a power cord like a one spot

Can power plus 2 handle 2 sppits? Thank you so much you really helped!

[@AlphatoneAudio]

Yes. Just make sure you don't exceed the current rating for any given port and you'll be fine.

[@garymarini6654]

Great information. I’m experiencing a ground hum similar to when a direct box ground switch is in the ungrounded position. Using a Strymon Zuma R300. Shure wireless into volume pedal-Boss OC-5 into Cloudburst then Kelley Omni reverb to direct box. Bought the Zuma because I thought my Onespot pro had gone bad. Sounded the same way as new supply. Tried each pedal with a onespot and perfectly silent. Went through each pedal the same way , all silent. Although I know daisy chaining isn’t the best idea I was forced to for Sunday service. Pedals run silent with 20.00 onespot but hum with the Zuma and Onespot pro . Same patch cables ,same outlet. Even went to a different wall ,circuit. Same results. I’m totally baffled. Any thoughts to try ?

[@AlphatoneAudio]

Gary, sorry for the delayed response. Did you try each pedal individually with the wireless unit? I would be curious is the wireless with so many buffered pedals could be the problem. The buffers in pedals can be of different quality as well. Have you tried the chain without the wireless? What are your patch cables? Have you tried a noise suppressor?

[@junos001]

Great video! OK, you have 1-4, 5-6, 7-8. Can you mix say, 4-5 with a Y current doubler without doing any damage to the power supply or the pedal being connected? I have a pedal that needs 500ma to run, so a Y connector to 5-6 work just fine. I tried connecting 4-5 and it also powers the pedal. I'm no good with this stuff. Any thoughts?

[@AlphatoneAudio]

If the pedal expressly says it requires 500mA I would say make sure to give it what it wants. Under powering a pedal can shorten its life even if it's functioning. If you plan to expand or upgrade to pedals that might use more power I would suggest you look into something that offers higher mA per port like the Strymon power supplies. Pedals seem to be getting more hungry for power with the more features they offer. Hope this helps.

[@anhthiensaigon]

If I for example have a cheap power supply with 5 shorted outputs, and another good isolated power supply with 5 lifted outputs, what if in a signal chain I connect the pedals' power alternately, like pedals 1,3,5,7 in a daisy chain and pedals 2,4,6 with lifted sources? In this way I should break every ground loop created by the shorted outputs, hence have a same effect as using 2 isolated supplies for the price of 1.5, am I correct? Thanks in advance, great video.

[@AlphatoneAudio]

If you truly have ground loops in your setup, this probably won't work. Ground loops can exist in both serial and parallel wiring schemes. I would just plug things in one by one and reconfigure as problems arise. Experimentation is key!

[@popitn2nd]

I have 3 pedals with different current consumption. Totaling to 420mA. Can i daisy chain these pedals and use the 500mA port?

[@lenkinadapa7241]

Great video! At about 7 minutes in you explain about using voodoo labs output splitter, does it matter what cable goes into either pedal -as far as the one with the white stripe? In other words -does pedal one or two get the white side strip?

[@AlphatoneAudio]

The white striped side of the splitter cable is ground lifted to eliminate ground loops. It shouldn't matter, but you can always swap them if you encounter any noise.

[@dougsmith4602]

As an electrician who also plays guitar, I wouldn’t ever suggest splitting in general. You are de-rating the wires which increases the chance of fire. In reality, you’ll prob never get full load capacity but on the off chance that you do, it’s safer to spend the money on a second power supply. They designed their pieces of hardware to accommodate a specific number of ports for a reason. Always better to error on the side of caution.

[@AlphatoneAudio]

Aboslutely! Splitting is never ideal. Thanks for the extra insight, and thanks for watching!

[@Darmugart]

Hi, can I to conect my line 6 HX Stomp with 1 cable to the Pedal power 2 Plus? Thanks. Nice video👌🏼

[@AlphatoneAudio]

No, the HX Stomp requires too much power.

[@lenkinadapa7241]

Thanks Jason awesome! I also do run a stereo rig and didn’t put the voodoo labs splitter in yet upon revamping my board. So I guess to avoid the problem of splitting the stereo signal as you mentioned with the Radial splitter, I should make sure that the the two pedals that are being joined by the splitter should be way in the front end of the board and connected together? In other words even though I am running stereo outs (with a Lehle ground and phase isolation) as the last in chain -this splitter should be ok because the pedals that are sharing the output split are two distortion pedals right next to each other?

[@AlphatoneAudio]

Short answer is you should be OK. But, you have to experiment. Certain pedals will share power better than others. Don't mix analog and digital, don't mix modulation and drive, etc.

[@bohdilama]

[@jojoagmon]

Awesome video! It really helped me to understand all of these stuff... Also is there a way to check regulation in the pedal power supply with the multimeter? Thanks!

[@AlphatoneAudio]

Thanks! You could always use a meter to check actual output voltage, but you would need a scope to see any real advantages the unit is giving you over wall power.

[@nathanschad8048]

Awesome Video! is the onespot Cs7 regulated? a review i saw from onespot said the they outputs were underrated. idk what that means.

[@AlphatoneAudio]

A regulated power supply is one that maintains a constant voltage regardless of load. All pedalboard power supplies are regulated, although some will allow an output to become unregulated with a switch (like the PP2+). As far as an underrated output, what they probably mean is that the advertised current capacity is higher than what the unit actually provides. Personally, I hear almost universal praise for the Truone units, so I wouldn't worry too much about it.

Can you elaborate on transformer vs SMPS?

[@AlphatoneAudio]

It's a pretty deep topic from an engineering standpoint. Basically, while switching power supplies haven't historically been popular for audio applications, the latest generation offer smaller size, greater power, and less proximity noise. Similar to how Class D amps are getting more popular.

[@MichaelMoore-od4jz]

nice video

[@AlphatoneAudio]

Thanks!

[@Mist_R]

You'd make a great teacher, if you aren't already. Question, I use something like the 1 spot you showed @1:06 9V 2000mA. I currently run 5 pedals daisy chained. The current consumption indicated on each pedal's manual add up to 205mA at 9V. I'm looking forward to add a new pedal. On its manual it says: Power: External 9V to 18V regulated DC adapter (center pin negative) with 300mA current rating. Consumption: 150mA. My first question is, is it the 150 or the 300mA that I should be looking at? I guess it's safer to supply it with the higher amount of power? But which one is it really? Second, do you think it will be fine to add that new pedal to my daisy chain? I don't wanna just try it and fry that expensive unit. If it isn't safe then I'm planning to get a brick.

[@AlphatoneAudio]

Some pedals, especially digital ones like the H9 in this video, take more power on startup than in use. So maybe it wants 300 on startup and 150 in use. For sure you won't hurt anything by giving it too little power, so I would say just give it a shot and see how it sounds.

[@bumblesnowmonster]

Nice. Thanks for the detailed explanations! Subscribed.

[@AlphatoneAudio]

Glad I could help!

[@toneboy6583]

So, I've got 4 - 5 pedals that draw about 5mA each would you daisy chain them off a single 9V 100mA isolated output?

[@AlphatoneAudio]

You certainly can! No harm in experimenting.

[@peterhara5847]

Jason, thank you for this!! If I have a device that I know draws 1100mA, can I use a daisy chain to take 1500mA from 3 isolated jacks to power this device?

[@AlphatoneAudio]

This is exactly what a current doubler cable does. It's just a parallel-wired adapter to combine two outputs (a voltage doubler is series-wired). I've never seen a three-way cable, but you could build one. More info on this in an upcoming video.

[@moseybeat]

Great video. I have a question on your thoughts about a Tripplite LC2400. I Was wondering if you think something like that unit having a 50w tube amp and a pedal power 2 plus would actually be doing anything noticeable to keep noise floor down if plugged into the wall in a bar or house. Best, Taylor

[@AlphatoneAudio]

It certainly can't hurt. Keep in mind that it will only filter noise from the wall power. There are plenty of other places for noise to get into your setup such as tubes that are becoming microphonic, single coil pickups in unshielded guitars, etc. Isolating unwanted noise can be a challenge, so make changes gradually to see what is working/not working.

[@moseybeat]

@@AlphatoneAudio thanks for the advice. The rig i run is quiet as can be at home and most bars, i did add the tripplite as a way to protect the tube amp in case of a voltage surge or brown out. Most of the noise i hear is coming from my single coils, so i know not a real way to fix that. Any thoughts on the d'addario solderless patch cables?

[@AlphatoneAudio]

@@moseybeat I'm not a fan of solder less in general. I believe solderless has only one benefit over soldered, and that's usability. Meaning, your average person that doesn't solder can get up and running with as many custom length cables as they need quickly. After that, I feel soldered cables win in every other measurement.

[@jeffreymaeatro2]

Great instructional video! New subscriber, and i already have a question. I was under the impression that as long as the milliamp rating did not exceed to total of the power supply it would work fine. For example, I have a flashback x4 that needs 450/500mamp (not quite sure), but i power it from one of the 250ma outs on my vooddo lab out and it works with no problem since my other pedals don't drawn nearly anything. Was i mislead? Thanks

[@AlphatoneAudio]

At the end of the day, if it works it works. Some digital pedals will have significant current draw on startup, but then draw less in normal use. Maybe the rating on the tc is on the conservative side?

[@jeffreymaeatro2]

@@AlphatoneAudio Thanks so much for the response. I believe it was Daniel from THAT PEDAL SHOW who said this. I was wondered how could the pedal isolate the signal but share the amperage. Either way, thanks again for the video!

[@MrAntisound]

yeah, just divide wattage by voltage and you have your ma requirement. Or multiply ma with voltage and you have the wattage.

[@Melomanodtc]

Thanks for this video! question, i have the power 2 plus, im planning on buying the eventide H9, problem is that im already using one of the 250mA outputs with another pedal. Do you think i could get the H9 to work using the double current cable but combining say the 4 and 5 output to get me 350mA?? Thanks in advance

Doesn't hurt to try, but I doubt it. You'd be better off using the wall wart with the accessory outlet on the back of your power supply.

[@XChristianNoirX]

Not sure about the specific ZOOM, but if the unit/pedal (or whatever it is) takes AC power and not DC power, the polarity shouldn't matter. I have a pedal that requires an AC to AC adapter and it doesn't matter which is negative and which is positive. If the unit uses an AC to DC power adapter (BOSS and most pedals in the market), the polarity matters.

When I plug only 1 pedal in the powersupply and another pedal in a wall socket it is very quiet (more quiet than when I use 2 pedals powered by different wall sockets).

Hi Scott. I'm a bass player that doesn't use pedals so go directly into my amp and it does the same thing you are describing. Usually when I first power up at the gig. Doesn't always do it but when it does, the symptom is....I'm plugged in and turned on. I have a pre-amp tube so takes a few seconds to warm up. Sometimes it comes right on from the get go but sometimes nothing come out like there's a problem. If I hit a string really hard it seems to jolt something in the amp and sound jumps out then it's ok for the rest of the gig. I think it happens a time or two just sitting idle on break. When up for next set and did the same thing. I have been worried about it and started carrying a spare amp just in case. Just wanted to let you know in case you are blaming the wrong component.
