Product Description

"Hum" in an audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60 Hz (or higher harmonics) hum transmitted by electrical wiring. Typically, these loops are connected via grounds, more commonly called "ground loops". The safest way to eliminate unwanted noise is with the CleanBOX II. Some examples of Ground Loops:The power ground of a synthesizer, connected to the signal ground of the synth, into a mixer?s ground, then into a mixer's power ground.The signal ground of a send effect (reverb, delay) into a mixer, and the connecting power grounds of the mixer and the unit.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 easily removes ground loops without any signal degradation.

It was inevitable that with a crazy and complicated rack system, some noise was going to happen. I bought this item on a whim and I will never live without it. I have a couple high gain preamp and a couple of tube power amps that are as noisy as a bratty 6-year-old. This device cleared up my signal with no degradation. For best results use right after the preamp and hear pristine tone.

After researching other products, I purchased this item and was very pleased with what it could do to reduce or completly remove the "HUM" I was getting from my equipment. Prior to using it I had thought that the problem was with the cords I was using. Not so...Great product for the price. Well worth the purchase.
