Adapting from Balanced to Unbalanced and Vice-Versa:

Problem: You have a stereo output from a CD player (tape deck, VCR, computer sound card or other consumer electronics gear) and you need to connect it to the balanced line inputs of your mixer (EQ or other piece of professional audio equipment). Actually, there are three problems: 1.) Your source has RCA connectors and you need to connect to an XLR input. 2.) Your source signal is unbalanced, but you require a balanced signal where you’re plugging into. 3.) The signal levels have to be matched properly.

Solution: Use a CleanBOX! Its RCA-to-XLR channel 1 takes RCA signal, matches the signal levels and then provides a balanced (XLR) output.

Problem: You have the balanced stereo output of a mixer (an EQ or other piece of pro audio gear) and need to connect it to the inputs of a cassette deck, computer sound card, VCR or another type of consumer electronics unit. The three problems above apply here as well (except your source is balanced, and you require an unbalanced audio signal).

Solution: Use a CleanBOX! Its XLR-to-RCA channel 2 takes a XLR balanced signal, matches the signal levels and then provides an unbalanced (RCA) output.

Problem: You want to mix your voice (and/or instrument) with a CD and record the mix on a cassette deck or computer. Now you need to interconnect three pieces of equipment; two consumer level and one balanced pro audio level (the mixer). You have to go from unbalanced RCA to balanced XLR and from balanced XLR back to unbalanced RCA.

Solution: Simply use both channels on your CleanBOX.
