The PreSonus HP4 Headphone Amplifier is designed to deliver clear and clean sound, with a wide dynamic range. It is loaded with professional features, such as a monitor output with level control and mute and a Mono summing switch for the headphone and monitor outputs.

The PreSonus HP4 Headphone Amplifier is a 4-channel headphone amplifier using high-grade components to ensure optimum performance that will last a lifetime. Are you and your session players and bandmates tired of straining to hear under powered headphones? PreSonus was too, so they created the HP4 headphone-distribution system. These headphone amps are louder than you’re ever likely to need for session and stage use, so be careful with that level control! Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to hear!

Simple and Versatile
Simplicity is the PreSonus HP4’s hallmark. You get left and right line inputs, left and right line outputs with level control, and the four headphone outs. You can sum the stereo signals to mono, adjust the individual headphone levels, and mute the rear-panel Monitor outputs while leaving the headphone outputs active. So while the PreSonus HP4 is simple to set up and use, it has all the features you need to create a versatile headphone system.

Compact and Expandable
The compact PreSonus HP4 can sit on a tabletop or can be screw-mounted to a standard rack tray (not included), where it requires just 1/3 rackspace. And if your needs grow, you can use the line outputs to feed the inputs of a second PreSonus HP4 or the larger HP60 headphone amplifier. So quit struggling with mediocre headphone amps. Get the PreSonus HP4 and hear everything loud and clear. You owe it to your music.

    Solid gear
    Adam G.

    This thing does just what it says. I use it with my Digi 002R and it give me headphone outs, handy volume and mute control, even mono summing just to check. I've got one of the headphone outs hooked up to a set of desktop computer speakers so I can A/B on them for a quick "reality check". Flexible, solid piece of gear.

    Presonus HP4... nice headpone amp!
    Ivette Torres

    I used the presonus HP4 in the studio when we recorded some drum tracks. It sounded very clear, powerful. It's convenients since it's so easily transportable. I would definitely recommend it to others. I had a rolls that was horrible! Day and night in comparison.
