Reddit reviews Behringer MicroHD HD400 Ultra-Compact 2-Channel Hum Destroyer

This is basically like coil whine. I had this with WoW and KRK's too! Basically just electrical interference from your graphics card being picked up by your KRK's - you'll notice the buzzing changes as your framerate changes. I fixed mine with one of these: https://www.amazon.co.uk/Behringer-MICROHD-Hum-Destroyer-HD400/dp/B000KUD2G4/ref=sr_1_3?keywords=passive+hum+destroyer&qid=1562644272&s=gateway&sr=8-3

First thing... Never remove a ground from a power adapter. You're removing the ground from the wrong place and it can be dangerous.

Something like this can help / fix the issue completely: https://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4

It's basically a line level isolator. It sits between your soundcard and monitors and isolates using transformers. It ensures that there is no direct contact between signal lines as it only transfers the signal via the transformer, one for each channel (left and right).

There are a few models of this sort of thing out there but the Behringer is good value and performs well. I've had one in between my computer and monitor and casual A/B tests show that is doesn't affect the sound in any perceptible way.

If you don't trust Behringer, google "transformer isolated line level signal" for more boxes that do this.

Lifting your grounds on your power will get rid of your hums, sure, but it also gets rid of the safety function that grounding pins play, which is in the event of failure of your device, the power flows away safely.

Hey I do this, and you might have read one of my posts, since I've been posting about it quite a bit in the past week.

Your observation about note detection are spot on. Rocksmith is intentionally lenient so as to give the user the benefit of the doubt. Hearing your sound from a real amp will absolutely clean up your playing. Some of the default Rocksmith tones are somewhat quiet, so it's often times easy for your guitar playing to get drowned out in the mix and miss out on some of the dynamics like natural feedback and sustain.

I use this thing to eliminate the ground loop. http://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4/ref=sr_1_1?ie=UTF8&qid=1422679298&sr=8-1&keywords=behringer+hum

You can do a test to see if it's ground loop noise by putting Rocksmith on a laptop and unplugging it from the mains. The idea is being that you only have one ground pin plugged into an outlet. There's a couple of other ways for testing and resolving a ground loops. The behringer unit isn't the cheapest way, but it's the safest for this type of temporarily created loop. It's a very reasonable price for a durable and functional unit.

I think playing with a real amp is a great idea and will improve your playing. If you have any pedals it'll also mean you have to tinker a bit to match the tones in the song. This can be handy for identifying and matching effects in songs. I love doing stuff like this because it pushes me to listen to everything carefully and figure out not only the notes I hear, but also the techniques and effects used to create the final sound.

I used one of these to fix it when I was using RCA.

Truthfully the in game sound is perfectly fine IMO and up to par with any DAW I've used, the difference is likely in what you're using to output the sound (the two 12" are going to sound a ton better than shitty macbook speakers or not amazing quality headphones).

That being said I'm splitting to the same exact amp for my setup with a behringer headphone amplifier and dehummer.

I've heard other people use tuning pedals or AB/Y pedals which may (probably) are a cheaper and better solution, but I can't personally speak to that.

The downside of this setup is that you're going to still need to keep your volume at 10 and your tone at 10 on your guitar for the best RS note detection.

This is probably what's commonly known as ground loop. This is caused by electricity going in a loop within your setup. Crossing wires such as power wires and speaker wires, coming in and our of your wall socket, computer, and everything plugged in together, will cause this to happen and does not necessarily persist only within your blue yeti, especially because you mute it and it still happens. You may have introduced new wires or devices that brought more electricity into the mix, causing this ground loop. Best thing to do would be to unplug devices individually from your setup until it disappears, and then you'll know the culprit. This can be fixed by using a ground loop isolator (hum/noise isolator), or by painstakingly going through your setup to find the culprit, keeping wires as uncrossed as possible, and with a lot of luck.

I personally solved mine with 3 of these and possibly even this if it applies to you. Good luck

Die Dinger haben halt nicht den besten Klasse-D-Verstärker, daher gibt es ein hohes Grundrauschen. Ich habe je 2xLSR305 und 2xKS Digital D80 mit dem Teil ausgestattet, jetzt nimmt man das Rauschen nur mehr <30cm wahr: https://www.amazon.de/gp/product/B000KUD2G4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Gibt sicher Alternativen, aber da kann ich sagen, dass es funktioniert. Andere steckt man einfach dazwischen, genau.

This little hum destroyer can probably take care of that. I started getting hum like that a while back on a split signal that ended when I added it.

My gaming machine is a 6700K, 1080ti.

My streaming machine is a 2700x with a 1070.

My capture card is Avermedia 4k: https://www.amazon.com/gp/product/B07DHSZC4K/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

My mixer is this: https://www.amazon.com/gp/product/B0039PPW60/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I have an AT2035 for a mic.

From there it's just an xlr cord, a couple 1/4 to 3.5mm cord to hook to my gaming computer.

I have two https://www.amazon.com/gp/product/B000KUD2G4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 to keep the hum away that might happen.

I have a Boss TU-3 tuner pedal I use to do the splitting and recently discovered
Behringer Microhd Hd400 Ultra-Compact 2-Channel Hum Destroyer
I added to the mix as I was getting some bad ground loop hum on the CODE25 amp.

Received mine today. Pretty sweet looper, but unfortunately I'm still getting some hum. It's definitely not anywhere near as bad as the Y-splitter, so that's a relief, but it's still bad enough that Rocksmith is picking up a "B" note whenever my guitar should be silent.. hmm. This seems like it's messing with note detection a bit, and (as with my Y-splitter) I end up having to unplug a cable during tuning to remove the hum, because otherwise I can't tune some of the high strings. Tried recalibrating, but no luck. I know it's not my guitar, because the hum still exists even when my guitar is unplugged, as long as the Rocksmith cable is plugged into the looper.

I did some googling for "Rocksmith hum" and found some recommendations for this $25 hum remover, so I'm considering that. After reading the other posts, I was thinking there'd be no hum at all even without the hum remover.. oh well.

Other than that, though, it's a great pedal. Lots of nice features, and the ability to transfer your recordings from your pedal to your PC over USB is great. Definitely a worthwhile purchase even in light of the hum issue when used with Rocksmith.

I had a very similar issue with my hs8 monitors and it turned out to be a ground loop problem. If you Google "ground loop speaker noise" you should find a ton of forums with people dealing with this. Since it only happens in one part of your house that's what makes me think it might be a bad ground somewhere in that circuit you're connecting to. For me what fixed my problems (and this fucking PLAGUED me for like 8 months) was just using this little guy: BEHRINGER MICROHD HD400
It's pretty cheap so might be worth a shot. This little box is the last part of my chain before it hits my monitors. But Google around for ground isolation problems and see what worked for other people as well. And also use a decent power strip for your monitors, not a chippy chappy old ass one you found stashed in your parents closet (we all havem).

I had the same ground loop issue when I first got my monitors (also using scarlet interface). I stuck this ( https://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4/ref=sr_1_1?ie=UTF8&qid=1526981643&sr=8-1&keywords=behringer+hd400 ) between interface and monitors and problem solved. Passive, two ins, two outs, basically a zero-gain transformer I think. Only around 30 euro too.

Had the same problem, horrible noise coming from my JBL 305 when my GPU was under high load. Bought the Behringer HD400 and it eliminated the problem completely. I personally don't notice any loss in quality, it sounds better since there isn't any extra noise in the signal. I have my DAC/preamp going into the HD400 with 1/4"-1/4" jacks, and then 1/4"-XLR cables going to my speakers.

Power conditioner, make sure the TS cable is nowhere near power cables (or perpendicular to them). If the noise gate plugin doesn't work, you could try hum destroyers.

I had the same issue with my setup. I'm have two JBL LSR305s running to my onboard sound of my desktop. I would often get a high pitched hum anytime I moved my mouse or whenever I was in the main menu of a game. I ended up buying [this](http://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4/ref=sr_1_sc_1? ie=UTF8&qid=1418913249&sr=8-1-spell&keywords=Humm+destroyer), which completely eliminated the hum coming from the speakers. If this doesn't fix your issue, I'd recommend running an external DAC like others suggested.

https://www.amazon.com/Behringer-Microhd-Ultra-Compact-2-Channel-Destroyer/dp/B000KUD2G4

https://www.amazon.com/Behringer-HD400-Ultra-Compact-2-Channel-Destroyer/dp/B000KUD2G4
put that before this:

I just went through the same thing with my usb dac. I tried a y cable with separate power source and then a ferrite cable. Nothing worked it was a ground loop. I ended up eliminating the noise with http://www.amazon.com/gp/product/B000KUD2G4/ . There are cheaper and more expensive options but this unit works great.

I am running the e10k to a little dot 1+ and I would get the same noise through the dac or sound card. Read more about it here: http://schiit.com/faq/amp-problems

Thank you for the response.

I picked up 2x balanced XRS to 1/4 TS cables to go from my mixer output to the monitors. No change, unfortunately. The same goes with a power conditioner.

I ordered this 'hum destroyer' which I hope I'm understanding correctly is an AGDC2, or ground isolator. I'll place it between my line out to TS and the input to the mixer. Hopefully that will help, as the output from the line out isn't balanced right now.

If that doesn't fix it, I'll probably have to return my 308s as I don't know what else it could be.

I've had SOME success at long last. After inspecting the cables that came with the set carefully, i noticed that they were not balanced at all. Just because I was using a balanced connection doesn't mean I was using balanced cables. I assumed they were without checking as they came with the speakers as part of a bundle.

You can check this yourself by the amount of rings on the tip of the cable. If there is one black ring, it is not balanced, if there are two, then it is balanced.

Anyways this reduced the buzz by about 60/70%. The issue is still there but at a much reduced level. I will be trying this Hum Destroyer to see if it will break the ground and remove the problem entirely.

Looks like you're using a mixer, so I would add in a "hum destroyer" in-line with each source coming from the streaming PC and the gaming PC into the mixer.

https://www.amazon.com/gp/product/B000KUD2G4/

You have a similar setup to what I have, and the noise sounds pretty much the same as what I used to have in my setup. What I had to do was add in two hum destroyers (https://www.amazon.com/gp/product/B000KUD2G4/), one in-line between each PC and the mixer.

I have a cord from the PC's speaker out, which splits into two RCA males for L/R (https://www.amazon.com/gp/product/B0094A1F3S/), and plugs into the hum destroyer, and then another set of cords from the hum destroyer into the mixer (https://www.amazon.com/gp/product/B00I0HPK6O/). Same setup from each PC (streaming and gaming).

After adding those, my sound is crystal clear now. So can't guarantee that will fix your problem, but it fixed mine, which sounded similar.

On the off chance that anyone has the same issue, buying this completely solved the problem without any noticable loss in audio fidelity. I have it in between my sound card and my speakers. I was very dubious, especially with Behringer's reputation for budget gear, but it's solved everything.

https://www.amazon.co.uk/gp/product/B000KUD2G4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

If you want to eliminate it for sure I'd go with a ground loop isolator. I had the same issue with my hd650s and it fixed it completely.

https://www.amazon.co.uk/gp/product/B000KUD2G4/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 This is the one I used but you'll need to buy cables to fit your setup as the ports on this one are all phono.

If you want to test if this will work try the dac on a laptop that's not plugged in, if the humming goes away then the isolator will fix it.

After a bit more investigating I came across this

http://www.amazon.com/gp/product/B000KUD2G4/ref=ox_sc_act_title_1?ie=UTF8&m=ATVPDKIKX0DER

For $29. I think I might go ahead and pick one up, I'll let you all know if it works

I have already done some research.

• This one i could use directly
  
  
  
• And this one, cheaper, where i would have to buy two 3,5>6,3 jacks.
  
  
  Are there any better solutions ?
  
  EDIT : I found this one wich is cheaper and passive. And i could use it by wiring my Xonar to it with my 3,5 TRS to double 6,35 TRS and then connect the Behringer with two 6,35 TRS to my speakers.
  
  I think I just answered myself but if someone has an advice say it !

Had the same exact problem - this little guy fixed it. No change to the sound quality.

specifically, here is one example: https://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4/ref=sr_1_10?s=musical-instruments&ie=UTF8&qid=1520458356&sr=1-10&keywords=hum+eliminator
but there are tons of other options you can look into.
People seem to have good success with these.
I believe they have different versions, and this one isn't one that has the lift/ground switch i spoke of.

You have a ground loop. I have a laptop and mixer setup (both on AC) that did this. They were connected through 1/4" audio plugs and had unbelievable noise for a bit. I used a noise/hum eliminator to separate the grounds between the equipment. This one from Behringer did the trick! http://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4 Put it in between the splitter and your amp and set the rocksmith mixer to zero.

I just got a pair of jbl lsr305s and Im getting a lot of hiss. If they're powered on but dont have any inputs the hiss barely noticeable but once i connect them to my pc it becomes significantly louder. Im assuming I need a better dac ((current one)[https://www.amazon.co.uk/gp/product/B0068IPE40/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1]) but before committing to getting a better one (probably an audioengine d1) I wanted to get some input as to whether that was the way to go.

I was also considering (this)[https://www.amazon.co.uk/Behringer-MICROHD-Hum-Destroyer-HD400/dp/B000KUD2G4/ref=sr_1_1?ie=UTF8&qid=1491419301&sr=8-1&keywords=hum+eliminator] to put between my current dac and the speakers as an alternative method.

Any ideas on which solution would yield better results?

EDIT: i plugged my dac (USB powered) in to a wall socket instead of powering it by my pc and it got rid of all my hissing. The hiss is barely audible; down to the level I get with just the speaker powered on with no audio inputs. I guess there was some interference or grounding issue.

https://www.amazon.com/Behringer-Microhd-Ultra-Compact-2-Channel-Destroyer/dp/B000KUD2G4/ref=sr_1_1?ie=UTF8&qid=1492456662&sr=8-1&keywords=buzz+box

Good point! I guess my question is biased, based on "new-ness", but to clarify I'm not implying that either company is intending to rip-off the other.

And about the noise.. I've diagnosed the issue. Running the H9 in Pre/Post, I'm experiencing a ground loop hum/feedback. And this is without using an amp's FX loop. So I guess power isn't the main issue, it happens with both the Eventide power adapter or by a high quality, isolated PSU.

Now I'm looking at something like this. I wish Eventide's site/support would build or recommend their preferred ground loop isolator, considering how often it is asked about on their forums.

Before trying any crazy DIY solutions, try using balanced cables with your interface or try a ground loop isolator or hum destroyer. It may cost a little, but you can just return it if it doesn't work. Get something like this:

Behringer MICROHD Hum Destroyer HD400 https://www.amazon.co.uk/dp/B000KUD2G4/ref=cm_sw_r_cp_api_E1FgzbPJ0HQXF

Try this it worked for me.

Kind Regards

Sound Blaster 3.5mm TRS To 1/4" TS into the 305s.

Have also tried motherboard 3.5mm out.

Same power strip. I have tried different outlets including different places in the house.

I cannot detect it with headphones at all.

Tonight I went crazy and ripped apart every single connection to my PC one by one then I went as far as removing the Sound Blaster, even removed my GTX1080 graphics card. I literally had nothing left connected to my computer not even a monitor. With just ONE LRS305 plugged into the 3.5mm motherboard out and the power cable to the PC power supply I pressed the power button and the Hums and Crackles were still present.

This doesn't happen when I connect the speakers using the same wire to my cell phone. It DOES however happen if I connect the LRS305s to my cell phone and plug my cell phone into my PC USB to charge.

At this point its obviously the PC motherboard or power supply.

My work around has been to put the volume knob on the back of the LRS to about 2.5 out of 10 and then crank up the DB settings on the Sound Blaster to +20 for each speaker. This makes it to where I can do daily tasks no problem and even enjoy some music at a moderate levels but I have noticed that the speakers don't seem to perform the right way when doing this even if the sound is being reproduced at relatively the same volume to my ears. Turning the knob up on the speakers even while lowering the volume in windows to compensate feels like it makes the speakers perform differently.

Also when I move around my mouse cursor on the screen it introduces a sort of electrical whine noise. And when playing a game it amplifies the hum. Again with the volume knob on on low settings I don't notice this.

My initial post was kept short with the intent to avoid having people to read this much but since you asked I figured I'd elaborate.

I'm so frustrated that I'm really considering returning the speakers and just getting the 2.1 Klipsch Pro Media at Best Buy for about 40% the cost. I probably won't enjoy the sound quality as much but at least I won't go insane trying to solve this issue without dumping more money into it.

But back to my original post about the Fiio and Behringer UC202. Do you have any info on this?

I also stumbled across a BEHRINGER MICROHD HD400 https://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4/ref=pd_sim_267_4?ie=UTF8&psc=1&refRID=WKE1J7XXB0PJZKX2PDG4. This seems like it might be exactly what I need. Any idea?

One more thing the cable I'm using is a Hosa Stereo Breakout 3.5mm TRS To Dual 1/4" TS. My question is why can't I find a 3.5 TRS to 1/4" TRS just TS? Is my cable still considered balanced? Can this be causing a problem for my setup? Sorry if that's a stupid question but I'm lost when it comes to this stuff.

Thanks!

Hey Guys,

It's only fair I come back to you on this, I was very close to buying the Schiit Wyrd to try and resolve this, luckily I didn't need to, I found a solution.

The TRS cables between my DAC and the LSR 305's were faulty and badly wired (custom cables), so there were essentially running as unbalanced. As soon as I swapped them out for some other cables that were balanced, I broke the ground loop and and the buzzing stopped completely.

You really do have to work through your cables (Thanks Elnrik), if you don't have balanced outs or a digital coax / S/PDIF input to your DAC available, I would take a look at this:

https://www.amazon.co.uk/Behringer-MICROHD-Hum-Destroyer-HD400/dp/B000KUD2G4

It's had some great reviews, it's cheap and I've seen it work in person for someone else with the same sound when they didn't have balanced outputs available.

Thanks again.

$25 on Amazon. I use these for all computers running into my setup. http://www.amazon.com/Behringer-HD400-2-Channel-Hum-Destroyer/dp/B000KUD2G4 They work great.

This is what I do too. I did however get some ground effect hum from both the amp and Rocksmith when using a Y splitter though so I had to use a hum eliminator like this one. Which of course added two more cables to the setup for a total of three instrument cables not including the RealTone cable. Worth it though.

I just got a Focusrite Scarlett Solo. When I hook up my guitar directly to it and run it in Ableton Live Lite, I have no issues. When I run my guitar into my Orange Micro Dark then into the Focusrite Scarlett, I have a lot of noise/hum, especially if I'm near the Scarlett. Now, my Scarlett is near my computer and if I'm recording, I'd like to be near the computer so I can control Ableton. Will something like the Behringer HD400 help with this issue, or should I look at another solution? I don't want anything terribly fancy, I just want to be able to record simple guitar tracks with Ableton to track my progress as I learn guitar.

This has been suggested as a solution for USB ground loop issues. Search this sub for ground loop and you'll find lots of discussion.

https://www.amazon.com/Behringer-HD400-Ultra-Compact-2-Channel-Destroyer/dp/B000KUD2G4

I recently built a new PC and I'm getting a ton of high frequency noise over my studio monitors. My setup is:

Focusrite Sapphire Pro 40 -> Alesis RA-100 -> Alesis Monitor Ones

The sapphire is hooked up to a PCI express firewire card with a TI chipset. There is no wifi adapter hooked up.

I'm certain the noise is coming from the PC because the noise will change as the PC is being used/the mouse is moved in some applications.

I do know that my power amp does not have balanced inputs. Do you think getting a power amp with balanced inputs might solve the issue? I've also considered giving something like this a try:

https://www.amazon.ca/Behringer-HD400-2-Channel-Hum-Destroyer/dp/B000KUD2G4

I had a similar issue and used this.

https://www.amazon.ca/Behringer-HD400-2-Channel-Hum-Destroyer/dp/B000KUD2G4

Not a guarantee but it worked for me

Have you considered the Behringer Hum Destroyer? It's what I use to get rid of pesky ground loops.

I read about the use of balanced cables or something like this https://www.amazon.com/Behringer-HD400-BEHRINGER-MICROHD/dp/B000KUD2G4 which i might try first as they are cheaper. Do you happen to know something about any of those?
