CLEANBox Pro Dual Channel Level Converter



CLEANBox Pro Dual Channel Level Converter

The CLEANBox Pro provides two channels of unbalanced to balanced level conversion, and vice versa, in a compact and portable unit. Balanced lines offer increased immunity to external electrical noise, so all you’re left with is great sound.

Important Note - This product is commonly used in outdoor Audio landscape systems, where source devices may provide less than the necessary 2V peak-to-peak pro-level signal, resulting in low speaker output volume.
Always in Balance

Always in Balance

Say goodbye to unbalanced AV receiver signals. Convert two channels of consumer-level unbalanced input signals into pro line-level balanced output signals quickly and easily with the CLEANBox Pro. Two RCA inputs and a stereo mini-phone jack are connected in parallel, while the balanced output feeds two XLR male jacks.

Come Unbalanced

Come Unbalanced

Need to convert a balanced signal to an unbalanced signal for a consumer amp? No problem. The other section of the CLEANBox Pro converts two channels of line-level balanced input signals into two channels of consumer-level unbalanced output signals. This side features two XLR female input jacks. The unbalanced output feeds two RCA jacks and a stereo mini-phone jack connected in parallel.

Make It Pro

The CLEANBox Pro allows consumer grade products to “play nice” with pro audio amplifiers. Use it with mixers, audio processors, laptop computers, computer sound cards, CD/DVD players, video gaming machines, MP3 player/recorders, powered monitors, and digital audio workstations.
