Works like a charm

lerxtdude, 26.05.2020

In my home recording setup I am using a laptop, connected via USB to an external sound card, which in turn is connected to a set of nearfield speakers. After upgrading my laptop I started experiencing disturbing noisy/crackling sounds on the speakers (but not on the headphones), even without audio playing.

As it turns out, this was caused by a ground loop, from both the laptop power supply and the nearfield speakers having grounded power cords.

After doing some online research I came across the Behringer HD400. It is now installed in-between the soundcard output and the nearfield speakers, and with this, the ground loop problem is completely eliminated. I am very pleased with this result.

The Behringer HD400 is compact, relatively cheap, and does exactly what it advertises: eliminate hum and break ground loops. The housing looks solid.

As always, the Thomann service was great, with prompt shipment and very fast delivery to the Netherlands.

Did exactly what I needed!

BBFPASTOR, 28.08.2020

A DI box is a simple piece of kit when it comes to using it. This wee box did exactly what it said and was simple to set up and use. Matched to stereo out to splitter cables into the box and the reverse out of the box, took care of the hum that was doing my head in.
Simple and easy to use, no power adaptors to muck with and nice and tidy to look at so no one but me will even notice it is there.
Pros; Best place to get it is from Thomann. Price and shipping were both right and fast. Easy to set up. Did what it said it would do. Worked so well that I have now ordered another for another feed into my board!
Cons; So far none.

It works!

JxHx the Thrillseeker, 28.10.2020

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.

A studio saver!

tomatoKetchup, 24.11.2017

Weirdly enough, there doesn't seem to be any other similar devices around. As always when I buy Behringer I am skeptical until I plug the thing in and see what comes out... I have to say for this little black box I couldn't be more delighted!

It just does what it says on the tin: my Moog Minitaur/Roland JU-06/JP-08, all usb-ed on my computer do not make any ground loop noise anymore. And, contrary to what I read on other reviews, I cannot hear any volume drop and the sound is absolutely not affected at all! On top of that the chassis is made of sturdy metal, and after dropping one a few times, there wasn't a scratch on it.

At that price it's just unbeatable... maybe that's why other companies don't even bother making their own versions!
