As someone who is new to pedalboards this was a fantastic explanation. Thank you!
This is a really thorough and informative video. I've only just bought enough pedals to worry about power supply issues and this !answered every question I had and some I didn't. Well done!
Thank you important issues explained perfectly
Thanks Sam and PMTVUK for the video and for keeping things simple and right to the point! 👍
Very clear and well-presented. Detailed but not overly chatty. Nicely done! I subscribed.
You are a legend! Great descriptions without information pollution. Unusual accent for me though, but it gets easier after 10 seconds. Thank you for your contribution!
I don't usually make comments on youtube videos but you sir definitely did a great job with this video. Everything is explained perfectly well and to the point. Thank you
Spent like 2k on pedals over lockdown, time to start a shoegaze band I guess.
i can relate
I’ll be the manager of the band and by manager I mean managing the reverb pedals.
@@mantisshrimp8019 🤣 LOL thanks for the laugh! 👍
Haha...what pedals did you get and did you form that shoegaze band yet? 😆
If you mount your pedal board on the ceiling above you, you could start a worship band instead... ?
Thanks! This was a very helpful video, I'm currently trying to make my own diy pedal board, as I've never had one before, and this was very helpful for choosing a power supply.
I've seen other videos from this chanel, but this is the one that got me subscribed!
I'm still almost half-way the video and this is definitely 5/5 for me! Great video man you explained milliamps correctly.
building my first pedalboard, this was so helpful, thanks a lot!
This is the best video of it's kind I've come across, thanks dude!!
Such a great video with useful, straight to the point info. Thanks! 🙌🏻
Perfect explanation about isolation, thanks a lot I was about to get a cheaper supply without isolation, and this video changed my mind!
Great information. Just what I was looking for. Thanks.
Brilliant video! Just purchased used RC-3 and was looking for the right 9v supply - plus I was wondering whether I would be able to connect an additional pedal to the same supply. Now I know how! Thank you!
At last a video that explains powering my board in easy to understand english. Thank you so much
Very clear and informative. Best video I've seen on the topic.
Thank you for this video. This was incredibly helpful!
Very important information. Thank you.
Wish I had seen this vid a couple of days earlier... Really nice info for newbies to pedals. I ordered the Sonicake 5th Dimension. The first one for me ever! Plugged in a 9V DC. Didn't switch on at all! Disheartened, and disappointed, I assumed it to be defective and ordered a replacement immediately... only to realize after 3 days that the adapter I used was Center Positive!😄😄😄
Thanks for posting. This was really helpful
Thanks - very well done, informative and interesting and short.
this was really really helpful. thanks!
Incredibly helpful, thanks very much!
Very informative. Thank you
those videos are worth a lot !!
Great great ! Very well explained indeed.
I just subscribed to your channel.
Greeting from canada
Thank your for the tutorial. It answered a lot of questions for me. 👍🙏
thank you for this video really learned a lot about building a pedal board
Great video....just what i needed. Thanks.
Solid explanation. Super useful video
Awesome video, helped a lot! :)
Finally, someone that can explain me this! thank you!
Thanks ...very helpful
marvelous video, thanks very much
Very helpful! Thanks a lot.
Thank you for the perfect video.
Thank you for breaking it down simply
and most important, THANK YOU FOR THE TIMESTAMPS......amazing.
Stay Safe.
My DC Brick suddenly overheated after years and they tell me that the transformer is burnt. So gone for repairs.
that was fantastic explanation. thank you very much!
this is an AMAZING video. Thank you so much
brilliant explanation thanks man
Very clear information thanks for sharing , best regards from Mexico 🇲🇽🇬🇧
I love Sam's videos. He has such a nice soothing voice and his explanations are top tier!
My only question regards the NON isolated MXR dc brick current. Is the maximum current of 2 amps divided between all the outputs or is each output capable of supplying 2 amps?
I just find it crazy that the non isolated PSU offers the most current, even more than the Strymon Zuma lol
Yeah it‘s combined 2A, it‘s actually almost like a daisy chain, the Zuma has likr 4.5 A
Very well explained and presented 👍👍
Fantastic vid , thankyou
Excellent advice
Great video.
And for the newbies we also use isolation tabs/little pieces of plastic for rackmount effects if you're lucky enough to have one in your rig to keep the same thing from happening with noise in your effects gear~great video keep rocking☆
Very good video
Great video
👍good job Sir
This literally solved all my pedalboard problems... i hope...
Great video! But can you explain the difference between a galvanically isolated and an isolated power supply?
Hello Sam, I find that the Donner DP-X and similar ( power bank ) saves messing about with plugging in the mains.( apart from recharging the batteries )......Regards to all at PMT.......Merry Xmas.....Howard uk veteran 85 and a leftie..................
I bet a lot of people learned some very valuable information watching this video today.. for the first time .
I love vid!🔥🔥 Quick question, is it ok to run 100mA to 500mA to a pedal with only below 50mA current draw? Thank you. 🙂🙂
I live in the USA. I don't want to mess up my new Truetone CS12. Where would I plug my Pigtronix Philosopher Bass Compressor into the CS12 and which cord would I use? The Pigtronix says: "Use with 9-18 VDC Neg tip Power supply." Input: 100 - 240 V; 50-60 Hz / 250mA; Output: 18V _ _ _ 300mA. Thank you for your help!!!
Some more Dagan content on PRS please? Cheers :)
Where are you keeping that strymon zuma hidden? Been after one for months and nowhere has them in stock
When I using the powerbank, is it good not buzzy? Or good for portable source
Prepare yourself for a long comment... I'm putting together a pedalboard with my Harley Benton Thunder 99 Power Amp Pedal, that is 24 Volts. The board will be powered with a Truetone 1 SPOT PRO CS12 power supply. QUESTION: I need to know if I can power the Thunder 99 pedal SAFELY, by utilizing 2 of the 12 Volt outputs and a Voodoo Lab 2.1mm Voltage Doubler Adapter Cable, and a Truetone CYR Reverse Polarity Converter Cable? The Thunder 99's power supply says it's 24V, 5.0-A. And it's center pin polarity is positive. Sheesh! That was a mouthful. I understand answers here is a long shot, but I thought I would just throw it out there anyway. FYI, I do want to stick with the 1Spot.
Hello...I have a boss PSA230S adapter, so can I used daisy chain to run my 4 boss pedals? All pedals run on 9V
So am I right in saying that the higher the output of the mA of a power supply, the better?
do you put the power under/near drives or digital to have less noise as possible?
Hello there
I've got myself a boss RC 300 and a couple of effects pedals
How do I power them all? My goal here is to be able to take my looper board and play anywhere I want without having the worry about the power?
Any help would be appreciated thanks
If you had a power brick and one of the outputs was 100mA could you run multiple pedals out of one output as long is it stays less than 100mA?
so if i'm going to have 3 - 4 pedal i should go with a daisy chain right
Hi, If am output says 18V can I plug a 9V pedal?
Reverse the polarity!
So is it ideal to buy all the pedals first before buying a power supply?
is it safe to use 1A power supply to a 300mA pedal?
Non-Brit here... what's a P & T (PNT?) store? ;)
Probably a noob question but is it okay to leave your power supply (like an MXR mini iso-brick) and your pedals plugged in all the time?
Idk but I would say so
Hi I have a question , a brand new energizer battery puts out 10 volts and it makes my cry baby wah wah sound great but when it gets used some and is around just under 9 volts it sounds dull can I used the variable output in my merry power brick and turn it up to 10 volts, is this ok to do?
So I'm a bit late and you probably already know the answer, but for anyone else reading this reply in the future: most of the time you won't encounter any audible issues when running a 100% analog effect off a higher voltage (say going from 9 V up to 12 V), although it also depends on the effect's internal "power section", this usually does not translate well if there are any digital components in the circuit, as those chips usually don't like any variations on the voltage and thus current that is running into them.
That being said, the voltage should only really bring a difference to the dynamic range of the effect before it starts clipping, which is usually a couple of dB per Volt, the "tone" is mostly handled by passive components such as resistors and capacitors (even inductors in some cases), as well as the harmonic distortion from the active components which is a consequence of their chemical composition, as well as some other characteristics from the input signal itself.
I'm a bit newer to small signal processing in electronics, so any further discussion on the topic is very much appreciated and welcomed.
Can you connect the boss power supply to a non boss guitar pedal?
yes as long as the voltage is the same and the pedal’s power draw is less than the power capacity of the adapter
This video should come with subtitles.
Is there a Way to Use Both an AC and DC pedal On a Pedalboard? Do you have to Buy Two different power supplies to Make it work?
I mean, you could technically run both on a "single" power supply, either if you can find a brick that has AC and DC outputs, or in each of the following cases:
a) Single AC supply: plug the AC powered effect directly to the PSU and connect a full wave bridge rectifier, along with a voltage regulator at the output of the PSU in parallel, then connect your DC powered effect to that new output.
b) Single DC power supply: connect the DC powered effect directly and use an alternator to generate the required AC for the second effect
c) Use some other off-the-shelf solution that accomplishes any of the above, which I'm not really familiar with
In any of these cases you are already creating a second power supply and not even dealing with the many security features of commercial ones, so I think you're better off just using 2 separate power supplies, one for each of your effects.
Also if I may ask, which effect pedal needs an AC PSU? I'm genuinely curious about that.
Call manufacturer of pedals need to send their own person fly with if you're going to do aboard then what your advertising is fine but individual post should come with their own power supplies. If it don't take a 9-volt battery in the back
MXR Isobrick is about $220.
This is like Pedal Power 301. I need to find 101.
My pedals are noisey and it comes from power cables. So annoying and no realt way to srip it from happening. Time happens and things move even with anchors. I need hwlp
How do you turn off the power supply? It's not in the manual, its not on Google, its not on any CZcams videos.
😊
I had no idea that Jimmy Hill worked in a music store!
Many new mini pedals draw in the range of 15-30 milliamps according to manufacturer specs. You are adding an extra zero to their load specs.
Nah all my pedalboard are battery powered now screw these psu crap. Thank you rockboard power xl.
You have forgotten CIOKS. Have you ever tried those? First of all, I am biased. I have known Poul for 30 years. But let me explain. I am positively biased as he is a professional who has provided powersupplies for pedals for all these 30 years. Check him out, maybe make another video about his power supplies. He's good.
No subtittles, what a pity! Thanks anyway!
thats what acdc means???
No Michael Bay effects in this video ?
"Some rarer pedals will use a centre positive power supply"
*Looks at BluesDriver on his floor*
*Looks at DD3 on the top of his amp*
These Boss pedals are not rare, Sir.
Joyo power brick. It's a battery power brick. No chord.
I'm a busker, the Joyo is what I use.
We all know it's pronounced Akka Dakka
Even before watching it I had a feeling that he will be promoting power bricks close to £100 just because.
Also, why MXR and other makers would produce non-isolated, buzzing power supplies to begin with? What guitar player wants any additional noise anyway? Shouldn't all power supplies come isolated by default?
That's why I prefer less known or even unknown brands that offer everything you need, including isolation, for a fraction of price of big names. Enough is enough, I'm after quality, not looks. Who cares about MXR DC brick brushed aluminium case if it bloody buzzes for no reason at all. That thing shouldn't even exist, let alone being sold for £90.
I would never ask you for any advice 😵💫👎
Should we trust the advice of someone that can't spell "centre"?
Both Centre (UK) and Center (US) are grammatically correct, just like Metre (UK) and Meter (US) although neither Americans nor British like to use that one very much!
Great video
