The PreSonus HP4 is a four-channel headphone amplifier with professional features in a compact and attractive housing at an excellent price. All inputs and outputs are designed as 6.35 mm jack sockets and can be configured for both balanced and unbalanced connections. The HP4 allows monitoring of audio sources through headphones. With its four independent headphone outputs, multiple people can listen to the same audio signal simultaneously. The mono switch on the front panel routes the left/right input signals monophonically to all headphone sockets.

Each of the four headphone outputs provides an output power of 150 mW and has its own volume control. The input signal can be routed to studio monitors via the monitor output and adjusted separately or completely muted using the monitor mute function. The HP4 delivers clear and precise sound reproduction with minimal noise and distortion. The PreSonus HP4 is powered by the included plug-in power supply.
