Behringer HD400 5-stars Reviews

Perfectly isolated PC noise

I have my PC's line in connected to the tape out of a mixer, then that mixer to another master mixer. Whenever the first mixer was off, I would hear the PC's crackling noise coming out of the master mixer, you know, the noise that gets worse when you move the mouse. I put the HD400 in between the PC and the first mixer, noise is gone.

Breaks ground loops!

If the cause of your hum or noise is a ground loop, this little thing is a great solution! It doesn't try to remove other types of noise, just ground.

An axual life saver

Bought several of these over the years !

I used them in live situations and in studios many times and always seems to work!

Great job Behringer

Perfect

My Roland TR-6s is very noisy when powered via USB. This little box made the sound crystal clean. Just perfect.

Does it's job, what more can you ask?

Does the job without fuss. It loses one star in sound because you can tell it has been added to the signal path, but it's not a substantial difference and not a deal breaker. Also loses one star on quality because one of the jack sockets is not as positive as the others. Overall, a low cost and effective solution to removing the mains hum between my mixer and the powered PA speakers. Recommended.

Awesome!

My studio monitors had a really annoying buzz. Behringer HD400 to the rescue. Dead silent! Cheap, easy and good fix.

Noise elimination

Great device!! I 've been looking for it for so long! My speakers produced a noise the moment I turned them on even by simply moving the mouse no matter the connection and the cables. So, now, with this device no more noise. It works perfectly!

Awesome

Did the job that was advertised to do

Works great!

Simple and well built, you just connect it and it works, solves tons of problems in complex setups.

Eliminates GPU coil whine in speakers

I bought this because I had massive coil whine in my PC Speaker caused by the GPU. After I introduced this between my PC DAC and my Speakers the coil whine went away. Solid 10/10, does the job and it's a pretty affordable solution.

BVery cheap

Gets rid of all those nasty hums.

Very happy - problem solved

For quite some time, my windows PC created a unpleasant background grinding / interference / vintage modem type of noise before I inserted the HD400 between my ZOOM R8 sound card and my amplifier. The difference was immediate and the unit is working PERFECTLY, creating a very quiet sound floor when I'm using my DAW or playing tunes from the desktop. One extra thing to mention - it is passive - no power is required. Just some jack plug connecting cables.

Excellent value and v v simple to use

Fixed My Audio Issues

I was getting a feedback buzz or hum through my monitors whenever I played video games and this fixed the issue 100$.

Definitely worth the buy if you're having buzzing or humming issues.

Magically works

Totally removed a ground loop on ADAM T5V's caused by computer. It needs more cables but it works ! (Setup is: Computer => DAC USB => Headphone amp/ Preamp => RCA => Behringer HD400 => Bal Jack to XLR => ADAM T5V's)

Probably the most amazing semi-modular synth out there.

This is now already a classic. The amazing tone, the design, the unparalleled possibilities in such a small device is unbelievable. For 2 years now I have been making the most crazy things with it and I have now a 15U eurorack modular system and the 0-coast is still there pushing the boundaries. Together with the 0-ctrl is a hell of a combo! Recommended to anyone who wants to start with modular synthesis.

Still in the package

I bought this to eliminate some humming, but the noise was already gone before I could even unpackage it. Was it in my head? Possibly it works by just being in the room! If so, it's magic. 5 stars.

Works as intended

When I connected my PC to my mixer it introduced a ground loop. This little box completely removes that. Very easy installation and does exactly what it says it does.

Also very nice metal construction, it looks like a proper piece of equipment :)

It works!

It's passive but the volume drop is minimal.

Works as advertised (of course you have to know what you want it for) and feels very sturdy, I bet it can take a beating.

The only (minor) downside is the inputs and outputs are too close together.

Magic box!

Use it with a Mooer GE-200 and Baby Bomb. They would sometimes get noisy, especially in cranked live situations. But this little box solved it completely. Dead silent!

Final solution to ground loops!

I had the usual mass hum on a Imac-saffireAI-power mixer-speakers, and especially when the imac was active the noise would increase frequency.

I linked this tool between the AI output and the Power Mixer input and ...voila': problem solved!
