ART CleanBox Pro Dual Channel Level Converter
The CLEANBoxPro provides 2 channels of unbalanced to balanced level conversion and 2 channels of balanced to unbalanced level conversion in a rugged, compact, and portable unit. Balanced lines offer increased immunity to external electrical noise, such as hum. Since a balanced system minimizes induced noise, it is the preferred method of connecting audio gear, especially when long lengths of cable are used.

One section of the CLEANBoxPro converts 2 channels of consumer-level unbalanced input signals into 2 channels of pro line-level balanced output signals. It has 2 RCA jack inputs and a stereo mini-phone jack input connected in parallel. The balanced output feeds 2 XLR male jacks.

The other section of the CLEANBoxPro converts 2 channels of line-level balanced input signals into 2 channels of consumer unbalanced output signals. It has 2 XLR female input jacks. The unbalanced output feeds 2 RCA jacks and a stereo mini-phone jack connected in parallel.

Each section has stereo level controls to optimize signal levels. An LED indicator lights when power is applied.

The CLEANBoxPro can be an invaluable tool in application areas including: home or professional recording studios, live sound, PA, permanent installs, DJ, AV, consumer Hi-Fi, podcasting and broadcasting. The CLEANBoxPro can be used with: mixers, audio processors, laptop computers, computer sound cards, CD/DVD players, video gaming machines, MP3 player/recorders, powered monitors and digital audio workstations.
