What is the difference between iFi GND defender and iFi DC blocker as I have KRK V6 studio monitors that has annoying buzzing noise even when my cables are not even connected? Which one should I get as I see you use iFi defender and blocker on studio monitors in your video? Please help. Thank you.

[@FireWalkMusic]

@@bonebap1096 the dc blocker is for eliminating toroidal hum from amplifiers. If you have any kind of ground loop related noise such as computer noise or a low frequency hum then you need the gnd defender. You just plug it into the power supply of your computer, and then you ought the power cord into the gnd defender.

[@bonebap1096]

@@FireWalkMusicMy speak noises are combos both like the sounds from your white Pioneer speakers(50-60 hz) and your Yamaha HS8. So get the GDN Defender you're saying?

[@Un_Pour_Tous]

What about a raspberry pi that has a analog amp that's powered by the same 5v power supply. No ground loop isolator works.

[@mic4ch]

How about Audioquest JitterBug FMJ? Would that eliminate the ground loop or is it the different type of the device?

[@nigelsilcock5921]

Great advice, I've had low level background noise/hum with my system for years and just went along with it......after watching this video today I solved the problem in 10 seconds.......ground loop noise was the problem, although ALL of my kit is sourced from a single plug socket in the wall (good), I'm using several extension boards and these were the cause of the problem.....my speakers were plugged into extension board 1, and my interface was plugged into extension board 2....... I moved the latter so that all three plugs used extension board 1 and the hum/noise stopped immediately!!

[@FireWalkMusic]

Hey, glad you got it sorted! 😀

[@reevespeters3717]

It's not quite fixed. I still have some humming. Any ideas of what else I could do? I got the hissing fixed however. Thanks.

[@MrTunes333]

Problem is, they are expensive, too expensive to buy and then find out its not the problem...

[@Stagoras]

Great video! Using a 5 y.old scarlet solo, didn't had the option to use balanced cables. Had it unused for more than a year. Had the noises when using mouse, bright images on screen... After watching this video and reading some of the comments, I changed the usb connection of the scarlett from the laptop to the usb-hub on my monitor. Problem solved! No more noise and a great satisfaction with the expectation of future listenings of good music in my work-from-home setup.

[@Preske]

I have the XX Hz ground loop problem. Your video finally gave me an answer what was wrong. It would slowly build up and start getting louder and louder. A wiggle of the cables made it go away So i always assumed it was a faulty connection, despite the cables being in good condition and not really moving. Now just to find what the actual problem is. They're not studio monitors, just old Cambridge Soundworks pc-speakers and subwoofer. Yeah I know, old AF, but I really like them. They sound good for me and they are very compact.

[@fepp88]

The only video on youtube that explains this in extreme detail! Thank you so much

[@EvilD85]

You, kind sir, had saved my sanity aswell. iDefender did the trick, no more GPU/CPU/HDD noise from PC finally! Sure it does cost some additional money besides audiointerface's itself, but now i got my Arturia MiniFuse completely silent with Yamaha's HSO50 in idle time. Thank you very much for so wide and detailed explanation!

[@FireWalkMusic]

[@PomBare]

Brilliant video. I usually can't get my head around technical issues but this was so clear I actually fully understood each step. AND I'm pleased to say that changing the unbalanced leads to balanced leads (I wasn't even aware which ones I had in) did the trick - I was very close to coughing up money on the idefender, but fixed my issue for free. Thank you FireWalk!

[@FireWalkMusic]

[@itikutok6568]

Thanks for the video! I got a brand new monitor controller and after I wired everything the way I wanted it, there was a light hum in the syster, I was gutted. After trying everything with my audio setup, it turned out to be the printer -> display -> computer -> monitor controller. It was a ground loop between the printer and the display (I use the usb connection so I don't use the usb from the computer). When I plugged the printer and the display into the same outlet, the hum finally vanished! Hope this helps someone, good luck and don't give up 😄

[@Infidel67]

That did it, isolated the cables away from others and used the same outlet, turned both JBL Professional 306P MkII Off before switching it out, turned them back on and the noise was gone. Great Video. Thanks

[@FireWalkMusic]

You're welcome! Glad you got rid of the noise 😀

[@morsymusic]

I just posted this comment on your other video but putting it here as well.... I got new KALI AUDIO speakers and started to hear a glitch sound (which I didn't hear on my iLoud speakers.) Everytime I moved my mouse or pushed up and down on the keyboard, I would hear the glitchy sound even more. Currently using the RCA inputs until my TRS cables arrive. After this video I started unplugging wires and learned that my HDMI monitor was the issue. Turns out these speakers don't mix well if the HDMI monitor is plugged in to the same powerstrip. SO the solution was to plug the HDMI monitor into a different power source (which so happens to be on the same wall outlet) Problem solved... Thank you sir!

[@abundantYOUniverse]

I can't believe your video fixed it instantly. I spent three weeks and a lot of money in cables off Amazon, and it was the ground loop deal. I had one plugged into a monster power strip and the other one on another power strip. Put both power plugs into the same one, noise gone! Thanks!

[@FireWalkMusic]

Glad to hear it! 😀

[@TraxtasyMedia]

Oh cool. I bought the ifi ground defender and was wondering why my humming on the headphones still is there and I asked myself, for what the other USB input is for. Now I got it and I should've read the manual precisely instead of just glimpsing shortly at it. Thanks for your neat and professional videos.

[@FireWalkMusic]

You're not the first one to make that mistake. Many just plug it in and think it just doesn't work. It needs external power in order to break the ground loop, by separating the power connection from the computer itself to the audio interface. :)

[@bluejayb1rd]

I'm a little embarrassed that all it took to solve this issue was cleaning up my wiring, but sometimes the simplest solutions work the best! Thanks for this video!

Hey, you helped me diagnose a problem that has been plaguing my studio for a long time. Best thing about it is that I was able to solve it without having to spend any money. Thanks so, so much! You da real MVP.

[@FireWalkMusic]

That's great! Glad you finally got it sorted 😀

[@les7118]

how you solved it?

[@muresic2948]

I knew it couldn't be an issue with my speakers because the GPU noise was coming through the headphone jack on the audio interface too. I was hesitant to spend $60 on the iFi+ but after trying every possible fix with drivers and cables I could think of with nothing working I finally caved in and ordered it and it was the only thing that actually resolved the issue, thank you.

[@FireWalkMusic]

You're welcome! Glad you finally were able to remove the noise. I know how annoying it can be! :)

[@miked2588]

An unused USB cable was causing the hum. While using the digital mixer direct to the camera via XLR, no PC was needed, so the USB cord was on the rack. I removed the cord from the mixer, no hum. Thanks for the 1 minute fix. I'll pick up some of those devices anyway. I'm sure they will come in handy later. Thanks for a well made video.

[@jersey21212121]

I had the same problem but as soon as I took my USB coming from my audio interface and plugged it into the USB that supplies power the one that acts like a charging port the problem went away. Make sure your computer comes with a dedicated USB charging port. Clean audio no noise anymore👌

Bro thanks so much same exact problem

[@mclovin1498]

Well dam. 😅

[@cmg]

Is there any device which does this to a Thunderbolt 3 connection? I'm going crazy about the interference on my Yamaha HS8 + MBP 14" + Apollo Twin X + Studio Display. As soon as I unplug the Apple Studio Display the noise is gone. It certainly has to do with the Power Supply from the TB connection but even if I use the Magsafe power supply it gives me the same noise as in your video with the difference, that it gets different/louder when I scroll through websites or watch a video e.g.

[@FireWalkMusic]

Sounds like a classic ground loop, especially since it goes away when you unplug the studio display. I would recommend the GND defender, which is what I'm currently using: geni.us/GND-defender You can plug the gnd defender into the back of your computers power supply, like I did. That should break the loop. I have both a USB and a firewire interface and the Idefender works great on USB interfaces, but obviously won't work for anything else, like thunderbolt or firewire devices. The GND defender separates the computer itself and breaks the loop that way. It's a little bit more expensive than the defender, but it works great and it's also more flexible. It can be used directly on the computer itself, or you can plug it directly into studio monitors, guitar amps etc.

[@cmg]

@@FireWalkMusic thanks a lot, will check it out!

[@jthrilla84]

Definitely going to try the IFI plus. I have the same focusrite interface. The mic is fine but when I record with my guitars I notice slight background buzzing noise.or white noise. Ill have to check if I have cheap cables too lol. This should be a big help. Thanks for the info!!

[@richardmay3727]

Regarding the "computer working" noise, I had this for years across two different studio monitors and multiple hardware swapouts on the PC side (all setups were unbalanced to balanced). Currently using on-board audio with KRK Rokit 5 G2 monitors. Finally fixed it last week with all of the below: * PC sleeve into both tips. * PC ring into right ring. * PC tip into lift ring. * Leave cable shields open on the PC side and connected to sleeves at the studio monitors. * Prevent Intel on-board audio chipsets from going into standby (low-power mode). All of the commercially available cable solutions tie all the sleeves together, send left/right signal into left/right tips, and who knows what goes on with ring when you plug TS into a TRS jack. Ironically the KRK's balanced inputs handle the unbalanced source better than their RCA inputs (which are even noisier). Apparently "problem solver" cables wired as above along with others using resistors to create quasi-balanced outputs have existed in the past but I've had no luck tracking any of them down. Isolation transformers should come with a warning about non-linearity -- cheap ones have significant roll-off at one or both ends of the spectrum. Thanks for making this video -- I'm sure it's helped many.

Just got studio monitors and getting computer noise. I got the IDefender and it definitely helped but my instrument interface is dead now.

I had an issue with constant buzzing for a year or so. I thought I loosened a capacitor within my PC when de-dusting it. Every time I moved my mouse in certain applications for work it would also produce a separate, louder buzzing sound. Originally, I thought it was my £20, 20 year old PC speakers. I got new ones and still had the issue. This is what made me think it was the PC. However, after watching this video I immediately went searching for a source of the ground loop once ruling out the speakers. It turns out it was the PC monitor. I plugged it into a separate wall socket and hey presto....the buzzing has gone. Took 5 minutes after watching the video to fix it. 3 of the 5 minutes was just restarting the PC after changing the plugs about. So thank you so much for this educational video...!

[@moochogusto]

I have been hosting karaoke at a friend's pub and we have been constantly battling with the sound heard at 21 seconds in this video. We have ruled out a lot of potetntial causes but did not consider a grounding loop. Hopefully we are able to move some cables around and solve the issue! Thanks for a great video.

The only video in the planet that explains these products. Well done! Though it’s still not clear to me which of the two(GRD or DC) I need so I bought them both so I can experiment.

[@FireWalkMusic]

You're welcome. They both do basically the same thing, all though the Idefender only works directly on the sound card, while the GND defender can be used on your computer itself, the monitors, guitar amp and so on, so it has a much wider use.

[@LoveMeBack]

@@FireWalkMusic In my situation the DC blocker directly on my monitors fixed the problem. My studio is now dead silent. Probably overkill but I kept the GND Defender and put it directly on my audio interface and I'm going to buy a pair of Ifi power cables, because I have all my power cables, audio cables and others laying on top of each other(no other option) and there is more equipment coming.

[@FireWalkMusic]

@@LoveMeBack Glad you got it sorted! The idefender is probably redundant, but I've seen people have issues related to noise from the VRMs on the motherboard, so it certainly can't hurt. There's nothing more annoying than constant noise in a studio. You're spending a lot of time in there, and any kind of constant noise can be maddening.... :)

Did you have to buy 2 for both monitors? Or just used 1 for the PC outlet? Thanks

[@scotthudson8363]

Great video and discussion of ground loops and computer noises - great, practical solutions too. One additional "culprit" could be a cell phone. I used to store mine near some of the signal cables (including the monitor inputs) and could hear clicks and pops (I assume the bluetooth, WiFi, and cell signals all radiate from the phone and were bleeding into the signal lines). If I leave the phone in another room, I don't hear the noise in my DAW (or speakers).

[@hiddenamericachannel]

I wonder if that's it....🤔

[@funcle8572]

Got to wonder why expensive speakers/monitors don’t have these integrated

[@AnonymousCookie709]

Because ground lifting can be dangerous depending on the scenario, especially if it’s done without consideration for common ground. Having a ground lift on a pair of powered monitors would mean an electrical discharge would need to find another route to ground, hopefully not through the user. That’s why DI boxes have a ground lift, because each unit either side of the DI box should be grounded individually and the connection between the two is what needs to be isolated. In essence they’re isolated from each other, not from ground.

[@Doggotron9]

[@CodySorgenfrey1]

For anyone who can't find the iDefender+ in stock, or finds it too expensive... separating the power wires from the data wires can be done DIY by splitting the cable, and using a 5w USB power adapter (like what comes with the iPhone). This achieves the same effect for GPU/CPU noise.

[@JoshFisher567]

Ironically iFi makes a USB audio cable that does this but it's like 350 bucks. DIY sounds like a much better solution. The USB connector connects to your DAC then it has 2 USB A ports, one for audio/data and one for power.

[@Matilonga]

I tried this viewing a tutorial, but my laptop doesn't recognize the audio interface (a Presonus Audiobox) when I plugged it into the female connector of the splitter. I tested it with three different extension cables (USB 2.0. as the manufacturer recommends), without sucess.

[@mexmax1657]

You got a tutorial for this?

[@kernelxsanders]

This was very informative. However, I notice this is focused on monitor output noise, or a noise that constantly comes through the monitors. I don't get noise like this unless I'm recording into my DAW and have the track's "arm recording" button turned on. So basically I'm only getting noise in the recording inputs, not the monitor outputs, destroying all the tracks I record. Sometimes I can mitigate that with plugins, but not always. Any ideas what's causing it in those cases?

[@musicalneptunian]

I have the same issue. Noise only occurs when I record audio with my focusrite in Reaper. Ifound that some usb ports in my PC reduced the noise a little.

[@Poopconnaisseur]

Im having the same issue, not the first time for me either. A couple fixes ive had was wiping the pins on the xlr cables with a cloth, also some wall outlets dont have grounds in the wall which is a pain in the ass, other than that you can check to see if there’s something wrong with your laptop

[@FireWalkMusic]

Glad you liked the video, and thanks a lot for the support! Much appreciated. Generally, the more stuff you have connected together like that the greater the chance you'll have ground loop issues.

[@BlenderRookie]

Okay, I have a question: I have a car subwoofer amplifier and subs connected as the bass channel to my atmos setup that's connected to my PC. The PC uses HDMI to the receiver and the subwoofer amp is connected to the receiver via a shielded RCA cable. My 120 volt AC to 14.4 volt DC PSU provides very clean DC current in excess of 100 amps. The subwoofer hums a tiny bit and hums more when the gain is turned up. However, the hum completely goes away when the PC and receiver is turned off or the RCA is disconnected. So, that means the source of the hum is from the RCA cable and what it's connected to. If everything is on and no audio is playing and I turn the receiver volume up, the hum is not affected and stays the same volume. Therefore the hum doesn't appear to be coming from the amplifier circuitry in the receiver and seems like an RCA ground loop issue. Is this something an RCA ground loop isolator likely would take care of?

The Scarlett Solo 3 is twice as expensive if not thrice and comes with only 56dB gain and using a Shure with it is a pain in the butt. Self self noice is about 55 - 47 dB which means it is unusable as is for Voice Over. It is noticable even when listening to the final video on a phone.

Great video and very informative. But what If I do not use a computer. I've had a hard time finding something when you do no use a computer in the chain; Just an old CD player that goes to a DAC and a DAC to an AMP and to some headphones. Apparently is my DAC that is introducing the ground loop hum because it goes away when I unplug it, which does not happen with any of the other devices. It uses a micro USB cable that goes tu an adaptar and to the AC Outlet, and if I touch any of the devices the hum goes away too. So what can I use for this purpose ?

Did you fix it? I'm having the same issue

[@deezulVo]

Hi, its a long shot probably if you reply to this but I really hope you do. My issue is, I am using the Line-In on my PC to listen to a games console through my computer headset alongside my computer audio. The console is plugged into my secondary computer monitor which I switch the HDMI input to when needed. My problem is I get what seems to be the gpu/computer interference described in this video, though only [or only noticeably] when this audio is plugged in and unmuted. Muting it in my computer's sound control stops, and just unplugging it also stops it. My problem is this is all done through typical 3mm audio jacks and not USB as shown in the video for that type of problem, so what should I get? I'm open to spending money if it will fix the problem. I have also already tried switching outlets and such and making sure everything comes out the same one, to no avail. Thank you very much for your time if you do see this and can help, and my apologies for treating your comment section like a tech support but I've been dealing with this for a few years now and I'm at a loss until I stumbled on this video.

When I plug the green end cable into the motherboard, there is a loud noise and even if I just slightly move the cable it is sooo loud. Also to that, when I mouse over (not click) a link, there is a pulsing noise coming from the speakers. Talk about annoying. I used these speakers on my old computer and no issues. Now on my new computer with a Gigabyte motherboard, there is. Old computer, Windows 10, new computer, Windows 11 if that helps? Thank you.

[@jameslawrencewirth]

I have Universal Audio Apollo twin interface with Mac. It is gorgeous with mics as a preamp, has a tube inside, which I'm sure enhances the audio signal for mics. I get a hum when connecting guitar or bass direct into the HiZ 1/4" input. Your post here appears the most thorough I have seen aver several years on this issue! i will try some of the fixes you recommend and get back to you, thanks!

[@sIIcAnton]

Dear FireWalk - thank you very much for the Video. I locate my Buzz and from where it is coming. My setup is I have one pair of active speakers connected to my av receiver. And I have a very strong buzz. I find out, that it is coming from the antenna cable. The antenna cable is going into the TV box - and from there via HDMI into the AV Receiver and then I have the buzz in my active speakers. I am struggeling which iFi product I need. Do I need to buy two GND Blocker for each active speaker or do I need a DC Blocker in the av receiver? BTW: The AV Receiver is connected to ONE Active speaker. And this active speaker is connected via a digital cable to the other one. I have Nubert X8000. I would really appreciate your advise. :-) Thank you very much.

I found a different fix for a similar issue I was having. Audio from Zoom H6 to ATEM Mini to Mac, annoying hiss and crackle. Turned out to be the DC power to the Zoom H6, it was sharing the same USB power brick as my Sony camera. Plugged them each into their own separate USB power bricks, audio is now crystal clear.

[@hiddenamericachannel]

So I'm happy to report..... I FIXED IT! And even though it wasn't any of the solutions you had on here, just your positive energy and cool vibes solved the problem! I first went into the BIOS and shut some power options off that were used for hibernation purposes and I don't use that. So I turned that off (had to take the CMOS battery out to reset the password). Then after that I rebooted the computer and went into the Real Tek mixer menu. I switched from 4 channels to headphones and also shut the unused input mixer channels off.... IT WORKED!!!! Sounds gone. It now works perfectly no annoying weird feedback!!! Your video and excellent narration was the motivation I needed! Thanks bro!!! My card is a Real Tek ALC 889....Yes it's old school. But it sounds amazing and came with the computer for free. I didn't even realize it had a sound card until I brought it home.

[@FireWalkMusic]

It's hard to say. Most musicians use external USB sound cards, as internal ones are more susceptible to noise from nearby components. However, it could also very well be a ground loop noise. You could test this by temporarily disabling the ground on the computer's power cable. Just put a small piece of tape or something to isolate it. If the noise then goes away, it's a ground loop issue. Do NOT leave it that way though, you must remove it afterward or it could lead to a fire if there's an electrical fault. If that "experiment" works then I would buy the ifi GND defender. That should take care of it. It is also 100% safe to use, and it will enable the ground if it senses a fault.

[@hiddenamericachannel]

This is a new and updated version of my original video about how to remove noise from audio setups and studio monitors. The previous video was quite popular and I learned that people were having all kinds of noise-related issues, some of which were not addressed in the video. This video includes much more useful information that should be helpful to those who are dealing with ground loop issues related to firewire audio interfaces or externally powered interfaces, as well as electric guitars and such. I've done much research into this, and I've also tested some of these solutions myself to confirm that it actually works. I believe this video will be helpful to more people who are dealing with noise-related issues such as ground loop induced hum, buzz, hiss, and so on. I know these are issues that many music producers and audio enthusiasts are struggling with, so please share this video and get the word out if you found this video helpful. :)

Thanks for sharing this great info. Do you know if I can use the GND Defender on my Integrated Amplifier? I keep getting this slight static/hissing sound. I've done a lot of troubleshooting and everything points to my Integrated Amplifier. Thx

[@jamesdavisjr1086]

Thanks for the video. I have a hiss and buzzing in my headphones when the volume is turned down. It's still there when i turn up volume, but whatever i I'm listening to will cover it up.

[@ilantaiebmusic]

Hi, thanks for this great video! I still can't figure out what my problem is. The set up is like this: Guitar (there are all kinds, both single and humbackers), directly to a pedal board with a power supply with isolated outputs. It connects with 3 pins to electricity, a transformer that has grounding. After that to a sound card that connects USB to the computer and also has its own power cable with grounding. And from there to the monitors (all connected to the same power splitter) and the stationary computer. which is also connected to the same power splitter. When I touch the strings of the guitar there is more silence than when I leave my hand. And so every metal part in a specific guitar. Not about other things like you demonstrated in the video that you took a cable from your sound card and touched a sound card. It only happens with guitars touching. What do you think the problem is? And which product do I need?

[@xjohnlangerijs527]

In my situation ground loop occurs after connecting my screen to the computer. Have used some shielding around my audio out cable, which takes away a lot. But found some low voltage on p/e and common. I certainly gonna try one of the mentioned devices, TX. Namasté.

[@LavaLemming]

Yesterday I installed monitors from Adam and have a low crackling hiss from the pc which gets much worse when opening up Reaper. I thought it was reaper at first, but the crackle is there low in the background even without the DAW running. I was just sick from disappointment after the $ investment, then I found your video. This gives me hope to track down the problem and not just return these beautiful studio monitors.

[@FireWalkMusic]

It is very rarely the monitors themselves. Did you try disconnecting the signal cables and keep the monitors powered on to see if the noise goes away then?

[@eman19857]

Wonderful video! However, we have got a Definitive Technology W Studio micro sound bar, and after shifting to our new home and installing it, we seem to have this problem, and we're not sure how to fix it. Could you help for this particular device please?

[@devingrubbs]

I've definitely run into all of those and thankfully sorted most of them. But my current noise battle is with the laptop I use to run my Ableton Live set. Tried Pyle Hum Eliminator and running a Radial DI in between my interface and the mixer. But there's always a static noise coming through the PA speakers. Running the laptop Powered or Battery doesn't seem to make much difference. That USB option you showed looks promising. Between that and upgrading my interface I'm not sure what else I could even try.

[@NickyPhillips-i4u]

This video was extremely helpful! Thank you. I am experiencing a buzz when I use my audio interface (SSL2+). I thought maybe it was my cloudlifter (I need one because I have a SHURE SM7B mic) but now I think it's a ground loop issue. The buzz happens completely randomly so it's not consistent. When it does happen, it goes away when I unplug my interface (powered through USBC) from my computer then plug it back in again. I am hoping by purchasing the IFI idefender will solve it!

[@LacklusterOfficial]

Hi. I have an interesting set of hisses and hums currently. I run a MacBookPro 15" (mid-2015), with FireWire going to a RME Fireface UCX. That one is powered by it's own power adapter. I've plugged in an Arturia Microfreak, a Yamaha SY35, a Yamaha RefaceCS and Roland SoundCanvas SC88ST. I also have an Elektron OverHub connected to my laptop. The SC88ST is powered by a BirdCord USB adapter (9V) from the Elektron Overhub - this results in noise. If I use a separate USBHub for purely powering the SC88ST, the loud low hum and high hiss is not there, but I'd prefer to use only one Hub - easier to port it around. The Elektron OverHub also has the RefaceCS connected to it via USB - for functioning as a midi In/Out port. If I have the USB cable plugged in, the RefaceCS emits a lot of noisy clicks and pops and digital whine, squealing. The minute I unplug the USB, all that noise stops. But I absolutely must have the midi, as this is nearest to my laptop. So I'm thinking getting a Ferrite Ring isolator for the USB cable might help. The SY35 is a story in itself, it's power adapter is an old one, I've been flipping the adapter and placing it nearer or further away from the Adam 7TV speakers, if it's further away, and plugged one way, it hums less. if it is plugged the other way, it hums more. I'm kinda ready to just buy a better power adapter for this, as this seems like it'd solve stuff, and the adapter smells like electricity and plastic. The Microfreak has an annoying highend hiss at loud volumes. As do the Adam 7TVs. So I've recorded 4 different types of hiss hum buzz, and am now looking at solutions. Unfortunately the regular "Just unplug the USB-cable from the Microfreak to reduce noise" does not do anything, and, again, for the Microfreak also, I need midi out and midi in via USB (my Midi USBHub is already overcrowded and upgrading to a 6x6 hub is way too expensive). Even went around rummaging in the cableboxes and found some TRS cables, but plugging TRS instead of TS into the SY35 had no audible effect, and I could only find 0.5m cables anyway and they're supertiny. So I'm looking at ferrite ring isolators for the USB cables, hoping that'll help with the RefaceCS squeal+hiss+hum, and then I guess I'd need to buy at least three iFi Ground Defenders but they're really quite expensive for a hobby, and switching all cables from TS to TRS (some of the cables I use are, i kid you not, RCA-RCA cables with adapter plugs on both sides). I'm also looking at buying some of those Mad Professor Red Cables and hoping that'd also assist in this situation. But it looks like I'd need to buy 400-500€ worth of stuff to get rid of all this noise, and there's hardly a fund out there that would help with financing this stuff. But at least I'm a little bit better versed on these issues now than I was originally. Weird to realize that after 27 years of buying and selling gear, cables and audio devices, I still don't know the first thing about ground loop hum or anything. This video of yours was really good at explaining this stuff, so thanks for it. I wonder if iFi have a Finnish retailer/importer.

[@karl3349]

Nice tutorial. Do you have any advice for guitarists that have electrical interference through their amps? Mine sounds like 120hz buzz that fluctuates in loudness but never completely goes away. A Furman. SS 6B Pro outlet strip doesn't filter it out. My guitar cables and pickups pick up the noise. Not sure if guitar cables with better shielding would help or not. Thanks.

[@Ajohnson5121]

Hello nice video, however you never explained how to fix the white noise / hiss you showed in the beginning of the video. Any advice?

[@FireWalkMusic]

Hi, I should have been more clear about this in the video. White noise like that is usually caused by electrical interference from other devices like nearby air conditioners, transformers, fans etc, which can get picked up or even cables nearby, so I would start by making sure that your signal cables are not close to any power cables etc. Also, make sure to use balanced cables. It could also be faulty equipment, or improper settings on your audio interface. If the gain on any of the inputs are set too high for example, then it can easily cause hiss like that. White noise can also be caused by ground loops, but I would start troubleshooting by testing out the free and cheapest solutions first.

[@raymondcrisostomo9778]

Yes, I have that buzz from my polk audio 12" subwoofer it drive me nuts. I replace wire able same thing. I will try your recommendations to plug the unit on the PowerBar or separate outlet. Those ifi defender are expensive.

[@damianxdemon]

this video was really informative but sadly didnt fix my issue everytime i go into FL Studio and go to input 1 for my microphone on the mixer track there is white noise coming out without even my microphone plugged in it also does this without being on my daw i can see the noise coming out of my inputs even on the focusrite control 2 app and if i plug my micophone in it still the same issue.

[@Vandikemusic]

Hello sir I have been looking for an answer to my question for years , yet i have not found anyone talking about it , and its tricky to explain but I try my best , I really appreciate if you can help I have 2 audio interfaces: 1 - Motu 828x. I use this as my main sound card for recording 2 - Axe-FX 3. I use this for my guitar effects. I use 2 inputs and outputs on each device to re-amp my guitar lines. 2 output from Motu ==> 2 input from Axe-FX 2 output from Axe-FX ==> 2 inputs from Motu so here is the problem: when I want to record, if both of these devices are connected to my computer, I hear a high frequency noise ONLY when I play something. the noise diminishes when I'm not playing . I did not find any of the noises in this video similar to my problem. Maybe the computer noise be the closest , but not similar at all. Now, if I unplug the Axe-FX from the computer. the noise almost goes away. Here is the tricky part, the noise comes from 1 of the outputs from Motu. if I unplug that output, the noise completely disappears. of course I cant do that because I need 2 lines for my guitars. I tried changing the cables, changing the jacks to another pair. yet the noise is still there. I wish there was a way could show you what I'm talking about Can you please help me ? Much appreciated

[@Tutku35]

Wow great explanation and the video!. I have a pair of iloud micros and they have a terrible white noise even without RCA connected. So these defenders don't work with the DC in port of the device or with the power supply it comes with. Maybe AC ipuifier or DC ipurifier2 would work?

Hello. This is a great video. I'm getting a humming noise in my powered Mackie HR824s only when I use HDMI out to a second display from my MacBook Pro.

[@jamesnoakes3205]

Great video, I was wondering though, I only get a noise on my phono line, none of the others. I have a record player and constant hum on the line. Now my house runs soley on solar and batteries, these are DC switching to AC for the powerline. I never had this problem before we moved a bit of the solar equipment. It sounds likey it could be DC interferance based on your video. Do you have any experience in this and possibly only the phono line. Many thanks

[@justingad]

Thanks for great Video. I've been struggling with what I think is a ground loop noise on my one Pioneer S-DJ80X. The other speaker is fine which made me think it may be a physical problem. I'm using XLR cables and a pioneer mixer. The problem is intermittent and granted that there may still be other sources of interference the sound goes away when I touch the back of the speaker or switch it off and on. Is this an indication of a particular problem? I have also tried most of the recommended solutions. Any ideas would be greatly appreciated.

I didn't see which device you used to remove the white noise. I am getting it from my RME Fireface UCXII interface. I hear it mostly with headphones and it's just a consistent hiss. Can you help? Thank you!!!!

[@jinjxmusic]

Thank you so much for this video! I think it gets me close and I wanted to humbly ask your recommendation about a product. I have a home studio set up - I use an iMac desktop and the USB of a Presonus Studio 18/10 interface. Going direct things are dead silent though I do like using a studio mixer. I have a Behringer x2442 and use a "snake" of balanced cables into the first four inputs of the interface. Because I mostly do cleans it's not that big of a deal though lately I've been getting the higher pitched digital ground loop sounds. I do not use studio monitors, only the headphone jacks from the Presonus interface. I would love to keep the studio mixer and believe it's the one adding noise. I'm not sure if I should go with the GND Defender for the power of the mixer or the DC Blocker in that same space. Is there a recommendation you'd give? I appreciate your time.

[@FireWalkMusic]

Hi, I have both and I world go for the gnd defender myself because it's more versatile. You can plug it into the back of the computers power supply for example.

[@elzurixmusic]

Hello! really glad you made a video about a topic that really nobody spoke about As for my case, I'm experiencing white noise hiss I own Kali LP6 and they claimed it's related to the class D amplifiers The noise issue remains when I leave the power cable on but removing everything else, it's identical to the sound you showed at 0:26 I don't think the cables are bad, it happens in both monitors, and it was like that from the moment I bought them (I just couldn't hear it enough in store to realize how bad it was) If you have any idea why or how to fix that issue it would really help!

[@FireWalkMusic]

Hi, some monitors can produce a slight hiss, but it shouldn't really be audible. If it's so loud that you can hear it just fine whenever they're just powered, then I wouldn't accept that. Annoying noise is the last thing you want in your studio. Do you have another type of monitor you could try to see if it's completely silent?

[@elzurixmusic]

​@@FireWalkMusic the hiss is noticeable, around 40 - 50 db from where I'm listening, I have the Logitech monitors, Z213, I don't hear any hiss from these monitors, completely silent, but they're not a good comparison because they're not studio monitors, and I don't have any other monitors to test that with. I can say that it sounds like the problem you had with your Adam T7V, is the same as mine, it sounds the same and both speakers from what I've read have that problem If you fixed the hiss problem in these speakers the solution might work also for me But then again from what I've read Kali says it's their class D amplifiers' fault, so it might be just the speakers themselves, but I really want to believe that I can fix the problem somehow, 40-50 db is not at all quiet

[@jlgonthebeat]

@@elzurixmusic do you have the same issue when you unplug the speakers and plug in a headset instead? Cause I seem to have the same hissing issue with my headphones as well, and I get the hiss and buzz sound with my studio monitors. My problem seems to be the power supply issue with my USB port on my computer. Considering my mic gets no input unless I turn the gain and the peak gain all the way up, then the hissing noise is so bad at that point I can’t do anything to fix it. My problem is most likely a power issue, if not then I just had the worst luck possible meaning everything I bought was broken

[@elzurixmusic]

@@jlgonthebeat I have an audio interface connected to my speakers, and nope, my headphones don't have that problem, so it must be the speakers, because even with just the power cable it still hisses, tried changing the cable with no luck, and tried plugging it to a different power supply, I'm lost at this point

[@tarkgundogdu8940]

@@elzurixmusic hello I have the same white noise issue with Adam T5V monitors. I think Kali LP6 V2 and Yamaha HS series do not have this problem in the same price range. They are much quieter. Since I like the T5V monitors in everything else, I just bought a pair of monitor stands and kept them away a few inches more. Just noting that the white noise is only audible when the monitors are in idle mode, when a song is played there is no noticeable white noise for me (just saying in case the situation might be different). The lesser white noise actually helps me to understand that the T5V monitors are turned on since it does not have an on/off led light in front of it. I hope this helps.
