The HP4 solves a problem every recording session runs into: everyone needs to hear themselves, and they all want different levels. Four independent headphone outputs, each with its own volume control, let every musician in the room set their own monitoring level from a single stereo source. The ultra-quiet noise floor means the only thing you hear is the music.

With enough power to drive virtually any pair of headphones cleanly and clearly, the HP4 handles everything from low-impedance in-ear monitors to high-impedance studio cans. The build is solid, the operation is dead simple, and it takes up almost no rack or desk space. A small piece of gear that makes a big difference in any recording or rehearsal setup.
