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
