Each of the four channels has stereo, unbalanced line level inputs that are converted to balanced mic level, left and right XLR outputs. Front panel input connections include gold plated left and right RCA jacks and a 3.5mm stereo jack. There is also an additional, left channel only, mono ¼” tip-sleeve jack, which allows each pcDIQ channel to be used as a standard direct box. Output XLR connectors are located on the back panel and each output is transformer isolated. The pcDIQ also features a stereo mix buss that combines any combination of the four channels into a single stereo mic level, balanced output.
