"Ground the source, float the destination." This is just another way of saying what David is advocating with his ground lift cable. Thanks for this great video, grounding is such an important and often misunderstood topic.

Trying to record an electric guitar i have lots of noise. To minimize it i have to find a certain position, i have to face away from computer, hold a guitar in unnatural position (not even 90 degrees, more like 100-110 degrees), and any deviation from that "safe zone" causes noise in my headphones (monitors are off, of course). It is either with single-coiled pickups or humbuckers (the first ones, obviously, worse). The StudioOne shows quite a high level of noise on a recording channel /quite hearable -33 to -44dB/ even with no sound coming through (when i don't produce sounds on guitar and/or when guitar is in "safe from noise" area). I am thinking about getting Electro-Harmonix Hum Debugger pedal... (?) What would you recommend to do and what products to use? That's the main question. Also... ~ I have too much noise when i turn the mix (comp/in) knob towards instrument (1) and a very little headroom for recording, either the signal is too weak or, after moving the gain knob just one little degree, i get distortion, noise and clipping (2). It is either with single-coiled pickups or humbuckers (the first ones, obviously, worse). PreSonus iTwo has a very little headroom, but i suspect that this is not the sole cause: maybe by increasing the gain i increase the noise (interface limitations+ground loop). (1) - waiting for a new interface Topping E2x2 (could/can't record anything with PreSonus iTwo or, recently, SSL2...SSL2 supposed to have a very low noise, but in my case (? why) i had even more noise...returned it while i could). (2) - waiting for a new interface and a ground loop breaker usb power injector for the interface C-port. For recording with a physical amp (Katana) i plan to get a Morley Humno Noise Eliminator. DI boxes (active and passive) seems like do nothing in my case (or make things worse): Behringer active DI20 gave lots of noise; DI Dolamo a bit Increases the noise compared to direct connection (TRS a bit more compared to XLR), but in nut-shell, it does not decrease the noise. Don't have any Gate pedal and not planning because it is tricky and i hardly play heavy music. In recorded track the noise is increasing in quiet times. I have a power conditioner Furman m8x, everything is connected there and it goes to one outlet. No noise-cancelling devices for pc or USB ports or 9V supply. All my guitars are in tact (grounded and shielded). The lights: no lights, some lights, big lights - not much difference. Thank you

Hi Dennis - sounds like you have an RFI problem. This is beyond the scope of what we're discussing here. It's important to differentiate between noise, ground hum, RFI - they are all different problems caused by different sources.

Anyone know this type of solution for UE plugs? Thanks and very good video. 😊
@dusty_wakeman6 ай бұрын
This is an audio ground lift (not an electrical ground lift), so it will work fine regardless of voltage or ac plug type. It will not interfere with EU safety requirements.

Questions/Problems (more). * Opening a project i got message that 970 files are missing. With Search i found some missing files, it became 270, and these can't be found anywhere (i've searched all folders /sub..sub_subs/ in my big folder dedicated only for StudioOne, all back up /mirror/ folders on 2 external drives). It is an old and very extensive 'precious to me' project, and ridiculous thing is, for example there is a guitar solo, i splat it at some points to get rid of some noise when i was not playing, now the solo is there only in pieces; all channels are ripped off here and there. Plus other issues. * Yes, as a rule i have a 25 minutes save; "use cached plug-in data on save"; "ask to copy external files when saving document" all on/checked. * I didn't change nor names, nor locations of working folders and files (though i have this project saved under different names as versions). * What i did is: i replayed some important stuff on left-overs and added two old stereo mix tracks of this project/song with different EQ settings (and with mistakes, quite unbalanced, but it is better something than nothing, there is no way i'd re-do everything due to circumstances and unrepeatable settings and instruments). I aligned everything nicely (time, buses, volume,..), corrected, blended everything nicely, and put vocals at the right level (up and with different settings, that's why mainly came back to this project), clicked "save". Logically, the DAW asked me "do i want to add these two stereo tracks/files", obviously, i clicked "yes" and...1475 files for each added stereo track started copying. In panic i pressed "cancel", but it was too late. Where these files are from, why?! Why these stereo tracks came with so many files? Where they went to? I checked the media folder to look for duplicates: no duplicates, but there are about 6000 files there (and some of them are not from this project). * But this is not all: i had plenty enough of memory space (workable 450-500GB free), now i am in the end of red zone with 78GB left. Agh.. * But this is not all again: i started clearing up the space on pc and the more i delete or move ...the lesser space i get on computer...now it is 50GB. * To free space and continue working (without interruptions and CPU overload) i thought that i would mirror the path, create the same folders in external drive, link the project to media files there, But i am afraid to make things worse in this and other projects (especially considering that freeing the space now works for me the opposite way). * What is wrong? How can i fix all that mess?

Hi Denis - wow -sorry you are having so many problems! All of this is outside the scope of what we are discussing here. We would suggest you get some help from StudioOne or your Pro Audio Dealer. You might also want to check some of the forums for the products you own.

It often involves experimentation. In an absolute worst case, you may need to use an audio isolation transformer to get rid of hum

I'm 68 a retired and David Royer, is getting old. He's babbling here. Talking about ground loops, yes. A big factor for the, Home Recording Enthusiasts. More so than the high dollar ticket Pro Studios. And so take it from me. A Top 50+ year Pro Studio Fixer person. Your current biggest problem with ground loops. Is, most definitely, from your, Computer. And other computer devices. As these do not use our, Old Fashioned Power Supplies. With electrical power transformers. No. These newer computer devices use a Switching Power Supply. Which has no big heavy, AC power transformer within. It uses a bunch of low-cost lightweight, semiconducting parts and pieces. And it is directly coupled to the AC power remains. With no isolation. From an internal power supply transformer. This thing is your biggest headache. And so what to do? You really don't have many choices here. All of your audio gear is, properly grounded. With your AC power cord, third round pin. And your audio gear is safe. From accidental electrocution. Whereas with your computer plugged in. You're not just getting, 60 Hz hum. You are getting multiple harmonics creating, Buzz. Buzzing buzzing buzzing. Enough to make you go mad. And there is an easy fix. The easy fix here. Is that, little gray or black or orange colored, 2 into 3 AC plug, adapter. To, Lift the Ground, on your computer. Now your computer is not grounded. So make certain. You got a good ground wire. Going from your, Audio Wire. From your gear. To the computer. Your computer is now grounded through your audio wire to your audio gear. And not via the AC plug. Where you are picking up your ground loop Buzz. Though there is more risk. This way. Then a safer route yet. Using the above recommendations. Is to, add in. An additional, Power Isolation Transformer. You can pick up from any, Industrial Electrical Supply, company. And this will then allow you to plug it into your, 120 volt, AC wall outlet. You plug in the transformer. Then. Via a multi-AC power strip. You plug that into the output of the transformer. You will have No More Ground Loops, at all. As your power and all of your gear is now Electrically Isolated. It's a great way to go. These transformers are relatively small. About the size of your fist. Mounted in a box. With a couple of electrical connectors in the box. To plug-in with. And you will be amazed! You will likely notice. All your audio gear has less noticeable recorded noise. And the sound may be somewhat smoother sounding. Because what you also don't know about ground loops? Even in your home studio. Without any buzzing or humming. You may feel your recordings are still, lackluster. They just don't sound like you think they should? And unbeknownst to you. Your ground loops exist and are in full force! But you're not hearing any humming or buzzing? So what's happening? The humming and buzzing that you do not hear. Is, now, modulating all of your buzz and hum free audio. Modulating it at 60, 120, 240, 480 or so times per second. And it actually sounds like Jitter or very fast analog tape flutter. In digital land it's called Jitter. And modulated audio without any humming or buzzing. Can playback and feel just like a lot of jitter. But how would you know? I certainly do. I have to solve these problems. And David Royer designs nice microphones. I love his microphones though I do not own any myself. I would get his basic cheap, passive, ribbon microphone. That's all you need. You need cloud Lifter. You turn your gain up all the way. And then you plug the output of your microphone preamp and/or equalizer. With its low level. Into a 1176 Dynamic Range Limiter or equivalent. And you turn up the volume there. You don't use a stupid cloud lifter. But there is a caveat there. Many microphone preamps also have available Phantom Power. No passive ribbon microphone really wants any Phantom Power. Though most will work just fine. A bad cable. An intermittent cable. A tiny little intermittent. Can result. In the death of your ribbon microphone instantly. And so? While I love a ribbon microphone into a decent microphone preamp. Into your cheap one. That has Phantom on you can't turn off. Without turning off the other microphones. A Cloud Lifter or equivalent. With a passive Ribbon Microphone. Actually creates a safety net. That keeps Phantom power. Away from your precious passive ribbon microphone. Kicks up the level a few DB. And you'll like it. Because it won't sound like a dynamic or condenser microphone. And you will learn its value. It's incredible, value. But hey. You don't need an expensive Dave Royer microphone. There are some cheap Chinese made, ribbon microphones. They are Absolutely Worthy. And an incredible bargain! And if you break one? You won't jump off of a bridge. For destroying a $1500-$3500, Phantom powered ribbon microphone. Whoops! Yeah don't do that. Get a cheap ribbon microphone. You'll love it. I had a nice collection. I used them more often than my, much more highly valuable, Neumann, U-67's, KM-56,, U-87's, KM-86's. I used the ribbon microphones much more often. Especially today with Digital Linear PCM Recording. That already sounds like broken glass. And ribbon microphones will tame that down. And they take EQ and a lot of it, very well. So sure I recommend all of those Royer Ribbon Microphones. And the Mohave series of condenser microphones. They really are very nice sounding. If you've got the money. Rich guys most certainly, do. The rest of us? Ha ha ha ha ha! Ha! None! So get yourself a Cascades or a Fostex, other Chinese, Ribbon Microphones and. And Ribbon Microphone Kits. Very much like the old RCA BK-44's. Those classic ones you see in the movies. Though the one on Larry King and Dave Letterman for years was the RCA 77-DX. And you were not hearing those. Those were props. I have a pair of those. They sound different from the 44 series. 44 series is a long geometry ribbon. The 77 and modern German derivations are a Short Geometry Ribbon, type. The RCA 44, AEA reproductions, Cole's, B & O,, Royer's and virtually anybody else. Those are more the, rounder sounding, Long Geometry Ribbons. They sound very mellow. Where the shorter ones have a little more zest to the sound. While still having the smoothness of a ribbon. Fine on a man. But made for a woman. Where have we heard that before? So the issue of ground loops is mostly from your computer power supply being direct coupled. So you must lift that ground. And make sure your audio gear is grounded. Because you are now grounding your computer through your audio gear. So you can connect your audio gear to your computer without humming and buzzing. Because it forgot the words. And David Royer should enjoy his retirement. As the Recluse he chooses to be. And who can blame him? Everybody wants his ribbon microphones. I mean who wouldn't? I wouldn't turn one down. I'd love to have one. And I can waive it at my RCA 77-DX's. Which I'm letting go of after about 40 years of ownership. And I dearly loved them. Never abused them. Never used them, recklessly. Never took them outside to be in a big breeze. Don't do that to you ribbon microphones. They won't, survive that. They are indoor microphones. Except for the RCA BK-5. Where the ribbon was inside the body of the microphone sideways. I never cared much for the sound of the BK-5, myself. But I knew other Radio Guys, loved them. I just had the 77's. And the BEYER, M-160's and 130 bidirectional. And a good old SHURE 300 long geometry ribbon. My only long one. As I don't have any 44 or Royer's. I dearly love, Dave Royer. And Wes Dooley from AEA. These guys have kept a great sonic piece of history, alive and well! When they all but disappeared. Starting in 1980. And all of the poor ribbon microphones that ended up in the landfills! I was sick over it! Oh my God! What a catastrophe! Yes. That really happened. As when I was transferred from, NBC Radio. Over to Network Television News On Air Operations. They showed me the microphone locker. And probably told me. The week before I got there. They threw out all of the old crappy ribbon microphones! And got all of these brand-new, miniature Sony, ECM-50 lavalier microphones! Hurrah hurrah! And I just staggered away in tears. Did anybody rescue any? I asked? A couple guys rescued a couple BK-5's. Ugh! No 44's no 77's and that other special one. That looks like a conglomeration between a 44 and 77. Used for a lot of Hollywood movies. I forget the model number as a senile 68-year-old now. 35 something? 53? I'm reaching. But they were all thrown in the trash. The week before. I'm still suffering over that to this very day. It was a whole Mike locker full of them. At NBC-TV News, Washington DC. And were made by our parent company, RCA. We still have the tape recorders and video recorders! Speakers, amplifiers, limiters. But they elected to throw out those microphones. What a bunch of morons! That's criminal! I'm still suffering over that. Those poor little ribbon microphones. Treat a ribbon microphone like you would treat a woman. Do not beat them. RemyRAD

Remirad posted quite a missive; it would be nice to see him edit it a bit. . . For starters, his point about switching power supplies is interesting; I have had trouble with a Sony flash card recorder if I use an ac adapter with a switching power supply. I would like to see him clean up his post; the more ideas about how to get ornery equipment to "play nice" together, the better. Now, as to his remarks about Chinese ribbon microphones, THAT is another story-- they are not up to ROYER standards but they can be fun to tinker with
