The CLEANBoxPro offers two channels of unbalanced-to-balanced level conversion (and vice versa), in just one rugged, portable unit. One one side, the CLEANBoxPro converts two channels of unbalanced input signals into line-level balanced outputs — it has two RCA jack inputs and a stereo mini-phone jack input feeding two XLR male jacks. The other section converts two balanced inputs (XLR) into two consumer-level unbalanced output signals. It couldn't be easier! With this kind of flexibility, the handy CLEANBoxPro deserves a home in every studio and stage toolkit.
