PatchBox is a passive "output multiplier" that can be used to distribute the output of a professional audio mixer to the inputs of peripheral equipment. PatchBox is ideal for feeding a mixer's output signal into DAT recorders, digital editors, computer sound cards, cassette and reel decks, VCRs, PA systems, dubbing racks, limiters, and other audio equipment. Both professional equipment with balanced inputs and consumer equipment with unbalanced inputs can be used.

PatchBox is compatible with any active balanced (transformerless) low impedance signal source that is ground-referenced. (Most professional mixers built since the early 1980s use this topology.)

From a stereo source, PatchBox creates 11 stereo outputs: 5 balanced stereo outputs and 6 unbalanced stereo outputs.

PatchBox balanced outputs, on XLR and 1Ú4" TRS connectors, provide a "unity gain" signal with a 600 ohm source impedance. PatchBox unbalanced outputs, on ...
