I've gained a new computer for music production to me recently and had since been very loud noise on my monitor speakers (Yamaha HS80M)!
Although I read in many forums that this often happens, but found little information to solve the problem, to some very dubious solutions that had to do with the reconstruction of power cords, what I would not do for security reasons.
In several music shops me a solution has been proposed in the area 100, whereby the expert could only guess that this solves the problem!
To The Product:
Actually, the product name is straight-forward and the unit also does what it should and no power !!!
Now this box hangs between the output of my audio interfaces and the Yamaha HS80M and the noise / bang is gone and so far (the first day of the test) I have noticed no change in the frequency response of the speakers.
Even though I'm Behringer minded skepticism, this little metal box is very highly recommended !!!
