Provides 2 channels of unbalanced-to-balanced and 2 channels of balanced-to-unbalanced level conversion.

The ART CLEANBoxPro audio converter provides two channels of unbalanced-to-balanced level conversion and two channels of balanced-to-unbalanced level conversion in a rugged, compact, and portable unit. Balanced lines offer increased immunity to external electrical hum, excelling in noise reduction. Since a balanced system minimizes induced noise, this method of reducing noise is the preferred method of connecting audio gear, especially when long lengths of cable are used.

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

The other section of the ART CLEANBoxPro converts two channels of line-level balanced input signals into two channels of consumer unbalanced output signals. The audio converter has two XLR female input jacks. The unbalanced output feeds two 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 noise reduction you get from the ART CLEANBoxPro converter can be invaluable in numerous application areas including, but not limited to, home or professional recording studios, live sound, PA, permanent installs, DJ, AV, consumer HiFi, podcasting, and broadcasting. The CLEANBoxPro audio converter 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.

Comments about ART CLEANBoxPro Dual-Channel Level Converter:

Perfect for my single use case, adapting consumer signal on 1/8" TRS-to-RCA, unbalanced stereo, to discrete stereo channels on XLR outputs. This replaced a much wonkier 4-channel Eurorack (really?!), the only used input of which was the 2-track. Very happy with this product, it's small and effective. My only small complaint is the lack of a linked master to control output level for both channels simultaneously. I fixed this, naturally, with a hardcore hardware hack; see the photo. Does anybody know somebody who wears braces? I think orthodontic bands would work better...
