hey, i have a terrible random "coil whine" in my speakers, can the isolator showed at 1:30 solve this ??? this high pitched whistling makes me crazy and could kill a dog's ears lol

[@tradrudeboy]

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.

[@cuba1956]

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.

Great video! Been a fan of your videos but never knew you had this one. I solved a grounding problem today with an RCA audio switcher that has a turntable, a CD changer and a digital mixer all connected to it. I had ground issues with each, and narrowed it down to the switcher. Got myself a ground loop isolator on the cheap, and it's working as advertised. Good to know of other solutions too, so this video will be a keeper. Thanks again.

[@StringerNews1]

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.

[@MikinessAnalog]

Every bit of my audio power requirements go through a 2500 watt 1:1 transformer for complete isolation. Also for when I need to repair a any devices that are shipped from the UK, the output is married to the input to provide twice the voltage, but you lose that isolation feature.

[@AlexFarranGuitar]

Mikiness Analog could you expand on what type of transformer you’re using? I’m having noise issues and it sounds like your solution could be worth a try. Thanks in advance!

[@LloydRobinson]

Good tips. My ground noise usually is my sampling input cable not connected to a sampling source. Sometimes it's too much Sustain and i panic, turning everything down but then realise it's Sustain.

[@no_categories]

Thank you so much for showing the actual soundwaves. So often on videos like this you just watch somebody listening to a difference and giving a subjective opinion.

[@Fallen_Grove]

Thanks for the tip about the shared power. I have my audio setup plugged into a different power source since it's far away from my computer. I couldn't figure out what was causing the hum on my setup and it was slowly driving me crazy. I even bought some of those grounding devices and it didn't help. Who knew something as simple as plugging everything to the same power source can solve this issue!

[@Noone-of-your-Business]

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!

[@craigconway4093]

Thank you for this, it got me thinking in the right direction. I have a computer speaker that is USB powered, when it was plugged into my desktop computer's USB port it made an annoying sound. To fix that I plugged it into a USB to AC adapter for charging a cell phone (5V 3A). And now the speaker works as it should.

As always, the best tutorials on the web !

[@0ne1roi]

Use a good USB hub guys! Instead of connecting your interface directly to your PCs, route the USB connection through a proper USB hub! I used my monitor (LG) and it works beautifully. The issue manifest when your interface draws power directly from the PC. Note that it is recommended that you connect your hub to the same power bar (and outlet) as your monitors.

[@wowiev]

Thanks to this one. It worked perfectly when I separated the power source of the usb while charging and using my audio speaker thru 3.5mm at the same time. No more noise/static sounds. Just simple solution.

[@HammyHavoc]

And what would you advise if your interface is a PCIe-based RayDat, and your convertors are already isolated from your machine as they connect via ADAT lightpipes, and are mains-powered?

[@theeville]

Thanks for pointing me to right direction. Had some really annoying cracks and beeps when recording my amp line-out. Bought a $0.20 separation transformer from Ali and sticked it into a plastic casing, making quite a beefy jack plug. No need for fancy boxes or magical cables.

The polarity inversion you observed is a flaw in the wiring of the particular ground isolator you tested. Let the manufacturer know and insist on a replacement, or buy elsewhere. That’s an inexcusable flaw that can result in out of phase sound between two related signals.

[@JimmiG84]

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...

[@onegumas]

In my case: active speakers connected to PC via DAC (toslink) and hiss. First way solved it - speakers were connected to other power boards - plugin into same solved my problem. Simple. Thanks

[@xpump876]

Over time I accumulated multiple and various power supplies (6 PowerOne Analog 4 to 8 amp, 9 Tiptop Bricks feeding Zeus distributors and 2 DIY) which accumulated multiple and various electrical noise and odd intermittent behavior. 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.

[@MrFlint51]

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.

[@BukanIbuMu]

Ground lift in my DI box doesn't remove the noise. It's weird.

[@MrFlint51]

@@BukanIbuMu What exactly are you connecting together? It could be that one piece of equipment has a noisy power supply; if so there is nothing you can do except change the power supply. Sometimes plugging everything into the same mains socket via a socket strip removes noise

A ground loop isolator is simply a transformer. It should not reverse phase (within the rated frequency range) unless cables were soldered backward (confused polarity).

[@underwoodblog]

I've tried some ground loop isolators and noticed a loss in the lows and highs. Low frequency sounds like bass and drums tended to get muddy and less punchy. When I see that a single good audio transformer from lehle or neutric costs 40+, I don't thing a 10 buck stereo one can have nearly the same quality.

[@jeffburgher3595]

Is there a difference between the 3.5mm ground loop isolator you used and a ground lift on a DI box? My Novation Circuit is outputting noise almost identical to your example, and a DI with lift wouldn't fix it.

[@_skysick_]

A ground loop isolator is very different from ground lift. Ground loops are voltage inequalities between the two circuits that are in contact with one another. A ground loop isolator tries to fix that inequality using transformers.

Your ground loop isolator is internally incorrectly wired. That's why the signal is inverted. Look for a better one and the signal wont be inverted.

[@Mcsteveberry]

???

[@brianhginc.2140]

@@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. See here: kzbin.info/www/bejne/nIfCmaZ8gJaApKM On the audio out left and right, each of the RCA plug's + and - just need to be turned around and your audio will not be inverted upsidedown.

[@RobertMaxwellMediaCorp]

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...

[@QoraxAudio]

Sometimes, so called balanced cables are fake, where the shield/ground and negative are shorted out, making it an unbalanced cable. Always check that using a continuity tester on the pins when you've bought a new pre-assembled cable.

I use triple beam scales to make sure my cables are balanced. I buy 2 at a time, same brand, and place each on on opposite ends of the scale. This method has been fool-proof to validate that they are in fact balanced.

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

Mine is caused by the boiler for hot water heating. So basically > turn off boiler > Hiss gone > Freeze to death.

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
