I first watched this video about a year ago, which definitely helped me identify the source of some of my frustrations. I finally just replaced all the outlets in my studio, re-grounded all outlets on the circuit that feeds my studio, and installed GFCI outlets on the most upstream point. I've also run insulated conduit to act as both cable management and power/data/audio cable isolation. I've added ferrite cores to all my USB cables and run voltage tests on all my audio and power cabling. This has allowed me to completely remove ground loop isolators and post-recording phase reversal filtering from my process. Short of a master power conditioner and UPS hard wired into my space, I've cleaned my entire electrical path as much as possibleand it sounds fantastic.

Great tips! I got one more. If one of your rack equipment produces hum when connected, check if it's not touching other pieces of gear in the same rack and is properly isolated from a rack rails (properly painted for example). Just take it out of the rack while connected to see if the hum disappears. Most of the gear's earth is connected to the enclosures and if enclosures touch each other in some cases, ground loop may appear.

Ground loop hum often happens in houses because with split phase wiring one must work to balance the legs to keep a voltage off of the neutral. It has *nothing* to do with the ground, so removing the grounding lug is not likely to fix the problem, and more likely to create an electrocution hazard. In cases where it does make a difference, that's because the ground line was returning current to ground in a "bootleg ground" situation. The problem here is that if someone touches an ungrounded chassis with one hand, and a grounded one with another, the voltage can be just right to stop ones heart. Far more effective to either hire an electrician, or learn to inspect your home wiring yourself if you have sufficient training. Another solution is to have a "balanced power" circuit installed for audio / video gear where ground loops are a problem. In the US this requires using gear at 240V or getting a step-down transformer. (I used a Furman AVR that takes 240V in and puts out 120V regulated, until I replaced it with a double conversion UPS that synthesizes the local AC so there can be no ground loops. Both are expensive, pro solutions.) Ferrite is very ineffective at line frequencies, so it's really only used to block radio frequencies. Ferrite chokes can be very effective in keeping high frequencies out of a system when used properly. Most VGA monitors had one at the end of the cable because they had three coaxial cables to carry the video signal to the monitor. Coax is unbalanced, so the shield is also a conductor, and RF inside the room can induce a voltage on the shield and enter the system. A ferrite choke absorbs the energy first. People who didn't know how it worked started putting ferrite on everything, thinking it would be a magic bullet, but it was a wasted effort. Recently I ran into a situation where every time someone talked on their radio, the SDI video signal to my monitor would go out. SDI uses coax, so I got an old ferrite bead that someone had put on a computer keyboard and put it on the SDI cable where it connected to my monitor. Problem solved! No reason why that balun should invert the signal. Chances are it was wired up the wrong way. But there's a use for the polarity invert switch on some audio gear.

Indeed, NO. You should absolutely NOT disconnect the ground pin. For all those who do not know, that thing is there *to save lives* !! In case of a short inside a grounded device with the live wire touching the metal _casing_ , it is the ground connector that takes care of your fuse box and immediately causes a cut of power on the affected circuit. Whatever you do, DO NOT REMOVE THE GROUNDING PIN on your plugs!

I get a low frequency humming sound from my headphones when I touch my motorized desk while it's plugged in. However if I simultaneously touch the metal part of a synthesizer or the computer case, it goes away. My solution has been to use a big, thick mouse pad on the desk so I avoid touching it directly. Not sure if I'm having a ground loop issue or some other problem, the noise doesn't sound like in this video, it's much lower in frequency. The audio interface and desk use 2-pronged plugs that are not grounded, while the computer and many other pieces of gear on the desk use proper grounded plugs so I suppose "ground" isn't universal across devices...

After noticing surprising voltage differences between ground on the MOTM cabs vs Eurorack cabs I read up on it and solved my issues by running a very thick copper ground to all said power supplies grounds. This was many years ago, but it made a huge difference. Another issue that's snuck up on me are modules that are starved for power. Modules will still function but if there's not enough surplus amps to draw on it can leave you wondering wtf. I have ammeters installed .. there cheap and provide a quick reassuring check.

This article explains everything. www.soundonsound.com/sound-advice/q-what-ground-earth-loop Using balanced cables (TRS or XLR) will reduce hum picked up from the environment by a long cable run, but will not prevent a ground loop. The ground lift switch on a DI box disconnects the cable shield/ground leaving both appliances earthed. I think a major problem nowadays is the growing use of external power supplies for everything. Most of these are double insulated and do not have an earth connection(the earth pin is usually plastic). If you have a keyboard with one of these PSUs and connect it to an amplifier with a proper mains earth, all will be well. If your amplifier also has an external PSU you won't get a ground loop hum, but you may get environmental hum pickup because your cable screen is not grounded at either end. You could block that by using two PASSIVE DI boxes. These use a centre-tapped transformer to provide the balanced signal, so use one in the normal way to convert unbalanced to balanced, run an XLR cable to the amplifier, then connect it using the second DI box in reverse. This will not work with active battery powered DI boxes because they will not work in reverse mode.

@@Mcsteveberry Yes, 1 thing you can do with the internal wiring of Ground Loop isolators is swap (by accident or intention) the GND and the middle pin RCA audio signal. Having the 2 backwards inverts the audio signal up-side-down. The device inside the ground loop isolator is a tiny audio transformer which is nothing more than 2 isolated coil loops of wire around a metal core. (2 individual ones side by side for stereo) With some designs, it is possible that on 1 side of this audio isolation transformer that the beginning and ending of 1 coil on 1 side of the transformer was wired backwards making the resulting audio invert.

I've had some trouble understanding the kinds of cables to use for either stereo or mono, and some weird problems surface when I just guess. For instance, on my 0-Coast synth, it has a 1/8 inch audio out so I need to use a 1/4 inch adapter on one end so I can plug it into my mixer. When I use a TS adapter, the signal comes through loud and clear, but for some reason when I use a TRS adapter, it's very weak and can barely be heard even when I crank the volume and gain way up. My mixer does accept either balanced or unbalanced cables on its inputs, so I'm not sure what to make of this...

The best solution for me is to use midi connections with my synths instead of usb.

Try these out - it may solve the problem
@loopop5 жыл бұрын
it may be worth your time to try the ground loop isolator - USB MIDI is faster and has better timing
@JoshRichmanDesign5 жыл бұрын
is that so? Can you point us to resources about midi connections vs USB midi? thanks@@loopop

is it normal to hear a humm sound when trying to use a stereo Line Mixer? Recenertly bought a Minimix 2 so i can hook it up to my tv for i can Use my Roku and my computer for my headphones. The isolator helped a bunch then i tried connecting a second isolator to a different channel and got a hum again. Any reason why that happened?

I think mine is a problem with the adaptor because when I disconnect it, the noise is gone. So shall I change the adaptor?

So I bought a ground loop isolator and it actually fixed the noise but now the bass sounds weird/muffled? Would appreciate the help

What if the monitor were plugged into a separate outlet that the laptop I’m using to record? And can a monitor broadcast RF into my mic’s TRRS line? PS I installed Ferrite beads on the power cable to my laptop, the mic cable, AND the headphones. But it didn’t seem to help. I can use a noise filter but it introduces a slight latency into the audio when live streaming.

Any one tried TOSLINK connection to isolate grounds?, I order several ground isolators like the ones in the video, waiting for them.

Iv been getting ground loop noise from usb mixer and korg nts1 and also the Roland t8 when it's plugged into a charger it's like a low hissy white noise sound and it sucks the mixer doesn't record the noise when I record my mixes so not a big issue and the Roland t8 is ok when it's charged so does not have to be plugged in but the korg nts1 has to be plugged in as it doesn't charge so Im gonna have to buy a dampner to stop it
