    • ART CleanBOX II Hum Eliminator

      ART CleanBOX II Hum Eliminator

      "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...

      Designed to solve the problem of rolling video hum bars caused by AC-line related noise due to ground loops in coaxial cabling. The 1184 also eliminates hum from low level stereo audio signals. Television displays and projectors usually have a hard connection between their inputs and chassis. Therefore, a ground loop may develop, leading to 60Hz current flowing in the input cable, which causes hum bars. Model 1184 uses active circuitry to isolate the input and output grounds. It also includes...

      Even though SDI is more immune to extraneous noise and low frequency components (hum) problems can still exist. As with analog signals, once you have noise in the signal, it is extremely difficult and costly to remove. Jitter caused by induced noise effects can compound problems created by unstable signal sources, poor re-clocking systems, cable attenuation and can be the demise of digital signals.
