CleanBOX II - Escape The HUM!

Welcome to the CleanBOX II from ART! "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 ART's 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 from ART easily removes ground loops without any signal degradation!

ART CleanBOXII - Filter a bit too much

This unit does what is supposed to, and some more. It filters out the bass. It's like an automatic low cut filter. My keyboard lost all the lows. It's like I engaged the 100 Hz high pass filter on the mixer. Definitely not good for keyboard or e-drum module. Should be great for acoustic guitar or other instruments that need the high pass filter anyway. I have the EB Tech Hum Eliminator HE2, and that model does not degrade sound (remove bass) like this one does.

Filters low frequency

This eliminates lots of low frequency along with hum. Not recommended. You need an isolator not an audio filter to eliminate hum
Rated 1.5/5

Didn't really work for me

I tried it at main different points in my signal chain and it didn't really work. I ended up getting the MXR Noise Clamp.
Rated 1/5

What is this? Cuz is not a noice reducer.

This devise did nothing other than reducing the input level and taking away lots of headroom.
