Review: Brilliant device , worth £14 all day long! - I’m going to start off by saying , I have a very bad EMI noise issue Between my PC , mixer and other audio equipment. I have hiss/static , whining and digital Hash noise. I bought a cheap £8 ground loop isolator , yes it fixed the noise but it completely ruined the bass , sounded like I blown my drivers and it was soft clipping my mixer Chanels. This one however is absolutely brilliant! The case is made of metal and it has a nice weight to it , the jacks have a nice click to them when inserting the cable which I like. This has fixed 98-99% of the noises I was getting with hardly zero frequency response change , like an extremely minuscule amount which really surprised me! The only very slight niggle I have is the moulded plastic packaging is extremely difficult to open and I had to resort to a Stanley knife which I nearly cut my finger off , just be careful 😂 Here are my personal ratings. Ease of use - 10/10 (very easy to use , plug and play) Device quality - 10/10 (feels solid and has a nice weight to it) Device look - 10/10 (looks professional) Sound quality - 10/10 (no sound changes at all) Noise reduction performance - 10/10 (absolutely obliterated the hiss/static , whining and digital hash noises) Value for money - 10/10 (worth every penny for £14 it’s a brilliant price) Overall , if you have issues like me and want to get rid of the noise that drives you crazy , GET ONE OF THESE!
Review: Great for home studio PC / Interface digital interference problem. - My use for this is was to try to remove digital intereference commonly noticeable when connecting USB audio interface to a monitoring amp ( or possibly powered monitors ) in a home studio PC / Interface setup. Not so much hum problem but the spitting/crackling data noise, and a sound as if someone is blowing a kazoo in the distance every time the mouse is moved. For me this worked perfectly connecting it between the Interface Line outs and the monitoring amp. No interference / hum whatsoever and, more importantly, no discernable degradation or alteration of the quality of the actual audio signal. I can't say for sure that it will be 100% for all configurations that people have. Hum / interference can be a bit of a dark art, but I can wholeheartedly recommend this based on my own experience. Noise not dropped / lowered etc, but gone completely as would be expected of the use of audio isolating txformers.

## Questions & Answers

**Q: My pedal board is powered by a multiport ac adaptor. i get mains hum when plugged into amp (not pickup hum, not pedal noise) will this fix the hum?**
A: Depends on whether or not your hum (by hum we mean 50 or 100Hz interference) is due to a ground loop. Ground loops occur when there are two ground paths between a signal source and a destination. In the case of a pedal board with power supply and a guitar amplifier you have the safety grounds from the power supply to the mains plug and from the amplifier mains input and that mains plug. A loop is caused when you add a second ground connection through the signal lead between the pedals and the amp. This loop acts as a single turn of a coil and picks up the low frequency radiation from the mains supply and various nearby mains powered devices. This signal leaks in to your audio path and you hear hum. The Behringer HD400 contains transformers that pass your audio signal but break the audio ground connection side of a ground loop.

**Q: Hello, i get a lot of buzz from my td-3sr.

will it help eliminate that?**
A: I don't know. Basically it stops ground looping. When two electrical devices are connected and the hum is you being able to hear them fighting to be earth basically. I had ground looping on two amps daisy chained. And it definitely works to stop this.

**Q: I use focusrite itrack with an ipad.get buzz if i plug a guitar in (mic is fine). buzzing stops if i touch the lead or focusrite. will this help me?**
A: Sounds like you have an earthing problem with your guitar, does the buzz stop if you touch the strings?

**Q: can this be used along with a DAC such as the Scarlett 2i2 to stop speaker buzz when connected to a pc?**
A: I think so. I assume you mean you've got the scarlett connected to pc thorough USB. And when you connect your monitoring equipment to the scarlett's rear outputs, you're getting buzz. In these circumstances you might have ground loop, so it's likely that this box inserted between the line outs and monitors will help.

### ⭐⭐⭐⭐ Does the job for me which is good enough but....
*by A***N on 20 January 2019*

This product done the job in eliminating static sound but it doesn't make the sound premium for me, as I still get minor hissing when I increase my volume. I bought these as I stream on twitch using a Behringer Mixer (Q802usb) but in my streams I was getting a horrible static background noise so purchasing these cured the sound and lets me listen to both my pcs at a decent sound yet if I was to blast the sound down my headphones it will create hissing and echoing but then I do have a entry level mixer. Overall review is good as it does its job properly but if you want premium quality then upgrade your mixer and hum destroyers.
