About Art Pro Audio CleanBOX II

The CleanBOX II Hum Eliminator, a powerful and innovative product by Art Pro Audio, is expertly designed to eradicate hums from your audio system. Hum, often caused by loop effects acting as antennas, can easily pick up a 60 Hz or higher harmonics hum transmitted by electrical wiring. These loops, typically connected via grounds or more commonly known as ground loops, can significantly affect the quality of your audio output.

The CleanBOX II Hum Eliminator, however, provides an advanced and effective solution to this problem. It is engineered to safely eliminate unwanted noise, enhancing the overall sound quality of your audio system. This high-quality hum eliminator is particularly useful in various applications. For instance, it can be used to break the ground loop in a synthesizer connected to the signal ground of the synth, into a mixer's ground, and then into a mixer's power ground.

Moreover, it can be utilized to eliminate the hum in the signal ground of a send effect such as reverb or delay into a mixer, and the connecting power grounds of the mixer and the unit. It can also be employed to remove the hum in the power ground of a guitar amplifier connected to a signal processor, which has a second guitar amplifier on the other channel, and then the second guitar amp's power ground.

The CleanBOX II Hum Eliminator is not just a hum remover; it's a tool that ensures your audio system delivers the best sound quality possible, without any signal degradation. Experience the difference with the CleanBOX II Hum Eliminator, your ultimate solution to ground loop issues.
