The best way to power pedals is all from one source without introducing any noise to your signal. Zeus is an isolated 80W power supply capable of delivering clean, isolated power to 10 pedals at once. www.nuxaudio.com/zeus.html www.andertons.co.uk/nux-zeus-guitar-pedal-power-supply/ This video contains paid promotion from NUX More details on how Science of Loud implements product promotion - www.csguitars.co.uk/disclosure #scienceofloud #powersupply #pedalpower Timecodes: 00:00 - More than a Greek Myth 00:43 - Zeus Feature Set 01:49 - Accessories Supplied 02:25 - Technology on the Inside 05:58 - PSU FAQs 08:34 - Powering a Full Pedalboard 08:56 - Sound Examples More from Science of Loud: Support on Patreon: www.patreon.com/csguitars Join Science of Loud Discord - discord.gg/uJHFgJRunb Buy Science of Loud Merchandise - www.csguitars.co.uk/store Website - www.csguitars.co.uk Contact - colin@csguitars.co.uk ___________________________________ *Description contains affiliate links.

Oh NUX haven't even seen it yet, I don't typically let companies see the videos ahead of release, and I wouldn't change anything on their request anyway. The reupload was because I made a mistake when describing the technology and had to pull the video down to film a correction. That was entirely my decision and nothing to do with upsetting anyone over swan buggery.
@@ScienceofLoud I love your commitment to integrity and getting facts right AND STILL ROCKING I don't even do music stuff let alone play guitar - but I learn a lot from your videos ! Thanks Keep it up!
Good on ya for showing the internals. I for one appreciate the science behind it being a tech/gearhead. All good isolated switch mode power supplies follow the same topology. The issue is filtering out the PWM switching frequency out of the secondary output coil. Once you achieve that through a snubber network of inductors, caps etc then you can get very clean stable DC voltage, and depending on the PWM chip can push very high current with little waste heat. Rarely however is each output over 500mA. Some PWM chips can do 1500mA or more per output, but the components get more numerous. Great video as always!
I purchased a Nux Zeus as it has everything I want. Plenty of sockets, multiple sockets with multiple voltages and a USB socket for powering my iPad while I take online lessons. Felt solidly built and no noise detected on my rig. All at a reasonable price, so great stuff. Sadly it had to go back as the USB socket wasn’t working. I tried multiple devices with multiple cables, all of which worked with other USB adaptors and sockets with my tester confirming the devices were pulling about 1A, less than the maximum 1.5A the socket is supposed to deliver. Fingers crossed it’s a one off 🤞
It's purple, so I automatically love it. The new EBS Gunsten has to be the best PSU on the market though, it's the only one that can fully power a Quad Cortex on a pedalboard.
As a professional computer nerd, who only dabbles in electric guitar for lulz, I actually understood a surprising amount about this PSU. The similarities to motherboard VRM considerations were striking.
That intro lol, such a good laugh Dang, those inside shots are beautiful, what a nice power supply, I will have to check them out, been looking to upgrade from my voodoo pedal power 2 plus
Great video, Colin. Really good to see inside the pedal. While I had no idea what I was looking at 😅, I'm glad that you did. It was pretty impressive. Thank you.
I had to pull that video down, amend some of the technical information that I got wrong, and reupload a more correct version. So the middle section of this video is reshot compared to what you watched yesterday.
NUX found the right man 🔥🔥🔥 Honestly FANTASTIC showcase. A to Z textbook. I’d legit dap you up lmao *Btw is it possible to combine 2 outputs and add the polarity cable to it? Working with tube cirquits here ✌️
Cool really. And yeah, can confirm about severe noise by random power supply that's not for audio gear. Also yes at first when I looked at one of these I wondered why they were so large and expensive hah. But I managed to daisy chain just few of my low power pedals with good single power supply I got from one of the pedals, just enough for all.
I might be sold. Smaller than my CS12, lighter, and doesn't have two mandatory 18v and one AC outputs. And all outputs are 500mA too, rather than 100mA and 250mA.
What’s the maximum drawn on the Zeus ⚡️? I’m used to a 2000 mA restriction?! I have a CS12 and was gonna add a CS7 to my silly big board. But would this be better? Already daisy chaining some lower mA drives and running an OCD, Wampler Belle and MXR 10 band stereo eq at 18v (they can be moved to a different board). With BigskyMx Timeline and H90 I’m looking at combining the last one from two outputs. Is that necessary? Eg the CS7 could power a HX Stomp from one output as long as overall draw was less than 2 mA. Please educate????
Yeah. I'm one of those with the funny voice. It's not quite falsetto yet, but it is higher than before I quit smoking. So you are saying that I need to drink a little more beer to balance out my voice to get it back to a more appropriate pitch? I don't know what to think about that.
I wonder if the size of the power supply can be reduced by using an external power supply plug to give it the right voltage. Like how they reduced the size of a Micro Dark by using a dedicated power supply thats outside of the amp. Aside from that, the PWM integration is pretty genius.
There are a lot of other power supplies on the market that reduce their size in this way - the new Walrus Audio supplies spring to mind. They'll have a small output board which mounts to the pedalboard, and have that connected to a laptop style powerbrick which does all of the mains switch mode conversion. However, it's a little odd to sell your power supply on its tiny size when all you've really done is put half the power supply in a different box further down the cable. Especially since those powerbricks are often off the shelf parts and half the development of the product becomes filtering out all the noise from the third party switching supply.
@@ScienceofLoud Maybe there are some benefits when it comes to heat and interference by moving the bulk of the conversion away from low-power circuits, including the power supply enclosure itself and all the other little noisemakers you have on your board.
NuX: "Let's name our power supply after a lightning god! Send it to that Scottish fella for review." Scottish fella: "DEHD YOU KNOW THA' ZEUS WUS A SEX PEST?"
You could certainly grab a second one of these - although as every outlet on this supplies 500mA, and most analog pedals draw far less than 100mA, it's entirely possible to daisy chain a few low draw pedals from a single outlet. That would further extend Zeus' functionality without having to purchase a whole other supply.
Why does there need to be a switching power supply per outlet? I'm probably missing something but I think one bigger switching power supply and an isolating transformer per outlet should do. What am I missing?
transformers are working on AC! A switching power supply also has a transformer (or at least an inductor (but then it is NOT isolated)). You want an extra transformer? Isolating transformers are good for (guitar) signals, not for DC.
So that it can be completely isolated. One transformer cant be shared by multiple outlets as it defeats the purpose of isolating each power slot. Some cheaper power supplies uses one transformer and claim it to be isolated. Well this one is truly isolated.
I THOUGHT it sounded wrong that optoisolators were the means of power isolation.... I've been spending the last day trying to find how that would work!
We use something similar in our studio. Can't remember the brand or name, because the things have been hidden underneath our FX boards for years. lol PSUs like this really make a difference, compared to a regular 9v PSU with 6x splitter.
