MI USA. Good as new condition. A pair of original 90's ProCo 4 channel headphone junction boxes. In box.
ProCo's HJ4P junction box splits a stereo amplifier output to 4 sets of headphones (150-600 ohm). Female XLR-type input with parallel male XLR-type loop output (for chaining multiple headphone boxes together). Master left and right level controls, switches for mono/stereo and left/right monitoring, and 4 stereo 1/4" (6.35mm) resistor isolated headphone outputs make up the rest of the HJ4P's features.
