The PreSonus HP4 is a 4-channel headphone distribution amplifier designed for both stage and studio use.
The PreSonus HP4 is a headphone amplifier loud enough for both stage and session use and provides clean, clear sound with a wide dynamic range. In the HP4, you get left and right line inputs, left and right line outputs with level control, and the four headphone outs. You can globally mute the headphone outs, adjust the overall headphone level, and sum the stereo signals to mono.
The HP4 can sit on a tabletop or can be mounted in 1/3 rackspace and if your needs grow, you can use the line outputs to feed the inputs of a second HP4 or an HP60. Chain as many headphone systems as you need.
