This MPL Hum blocker ground plug directly puts to ground an audio system.

Several DC power supplies (swirched-mode) cannot be physically and therefore electronically connected to ground. In certain cases, this problem can cause noise phenomena. This is demonstrated by humming, crackling, or even sometimes whistling.  

The Hum blocker provides a direct connection for the phono preamp, amplifier, or turntable to ground. In order to do so, all you have to do is connect the Shuko plug (with its neutral and phase terminals removed) to your power strip and then connect the fork to the phono ground screw (recommended) or to a chassis screw on the amplifier.

This avoids potential differences between the different devices and thus limits different noises and humming. The quality of the sound restitution is greatly improved because it is free from all sector noises.

Incredibly efficient!

Parfait !

Il y avait toujours un bourdonnement entre ma Rega RP3 et l'ampli Rega Elicit, celui-ci a complétement disparu avec la prise Hum Blocker.



Dopo mille tentativi il rumore del prephono ds2 del project è stato eliminato. Era un problema della terra.



Relié à mon ampli Yamaha Rn 803d, le bruit de masse du phono à disparu.
Super produit.



Acheté sur les conseils de Franck afin de régler un problème de buzz électrique lié à mon ampli Marantz non relié à la terre.
Aussitôt la prise branchée, aussitôt le buzz disparu !
Merci pour l'identification du buzz et le bon conseil d'achat !
Prix un peu élevé néanmoins, seul petit bémol
