ART CLEANBOX PRO - Dual Channel Signal Level Converter

CLEANBoxPro provides two channels for converting unbalanced to balanced signals, as well as two channels for converting balanced to unbalanced signals, all in a rugged, compact, and portable case. The balanced line offers resistance to external electrical noise, such as hum. Since the balanced system minimizes noise content, it is the preferred method for connecting audio equipment, especially when using long cable lengths.
One section of the CLEANBoxPro converts two consumer-level input channels to two professional-level balanced outputs. It features two RCA input connectors and a stereo 1/8" mini jack, connected in parallel. The balanced inputs are implemented via XLR connectors.
In another section, CLEANBoxPro converts two professional-level balanced input channels to two consumer-level unbalanced outputs. The input has two female XLR connectors. The unbalanced output features a dual RCA connector and a mini jack connected in parallel.
To optimize levels, each section has stereo volume control. An LED indicator lights up when the device is powered.
CLEANBoxPro is an invaluable tool in application areas (but not limited to): home or professional studio, live sound, PA, permanent installations, DJ, AV, consumer HiFi, podcasting, and broadcasting. You can use CLEANBoxPro with: mixers, audio processors, laptops, computer sound cards and interfaces, CD/DVD players, game consoles, MP3 players/recorders, active monitors, or digital audio workstations.
