Quality 4-channel headphone amp at an unbeatable price!

With excellent specs, low cost and compact size (1/3 rack width), the HP4 from PreSonus is a great tool for project studios or live monitoring applications. The HP4 accepts unbalanced or balanced inputs or outputs (¼” TS/TRS). The input can either be set for stereo or mono. The mono selector button on the front channel simply copies both inputs to both sides.

The HP4 features four discreet headphone outputs on the front panel, each with its own volume potentiometer and 150mW of amplification per channel. With a -95 dB noise floor and wide frequency response, you’ll be assured of accurate audio with no noise.

You can use the HP4 as a controller for your headphone mix as well as for control room monitor speakers. A separate volume potentiometer controls monitor speakers that can be muted using the MONITOR MUTE button. The HP4 is powered by an external wall mounted power supply.
