Need more inputs? Ever wanted to plug a tape player & a cd player into a mixing console, but didn't have enough channels? The JIB/R will allow you to sum two stereo sources such as a tape, cd, mini disc, or mp3 player, and combine and convert them into one mono XLR or 1/4" output. This allows one channel to be freed up for other important inputs. The JIB/R also has a phantom block circuit which prevents phantom power going to the input sources. - Combines (sums) two stereo CD or tape players into one mono (XLR or 1/4 inch) output - Frees mixer channels - Phantom block on the XLR prevents phantom power from reaching CD/tape players connected to the RCA jacks
