HD400 Review

JesperCFC, 15.08.2013
I purchased the Behringer HD400 as i have encountered ground loops at some venues and practice spaces due to my use of the 4 cable method between a tube amp head (peavey 5150II) and an external pre-amp (digitech GSP1101).
This little device when placed in the send and return section got rid of the ground loop hum problem easily.
its small and easy to fit either in the back of a rack or ontop of an amp head
the only downside is there is a noticable drop in volume when using this product. its nothing to bad, 4dB at the most, easily cured with more volume on the amp head itself

all in all a great, cheep, effective and easy solution to an irritating problem. if you have ground loop hums you have no excuse not to purchase this product

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!
