Connect Audio Gear with the ART Pro Audio CleanBox Pro Level Convertor

The CleanBox Pro is a convenient solution for connecting consumer A/V and professional audio equipment.


  • 2-Channel Balanced/Unbalanced Level Convertor
  • 2x XLR Inputs and Outputs
  • Stereo RCA and 1/8-inch Inputs and Outputs
  • Independent Level Controls for Balanced/Unbalanced Outputs
  • Power Adapter Included


It provides two channels of unbalanced-to-balanced level conversion, and two channels of balanced-to-unbalanced level conversion. The balanced signals use XLR connectors, the unbalanced signals use stereo RCA and 1/8-inch TRS jacks, and there are independent volume controls for both the balanced and unbalanced output levels.

Balanced lines offer increased immunity to external electrical noise and hum, and are the preferred method of connecting audio gear, especially over long cable runs. Need to get the analog output from a laptop, phone, or disc player to a mixer or PA system, or vice-versa? This is the box.

Please note that, unlike other CleanBox models, the CleanBox Pro is not a transformer/isolator. If a solution is needed to eliminate ground loops, check out the CleanBox II and DTI.
