The PreSonus HP4 Headphone Distribution Amplifier:

Are you tired of having to strain to hear your headphones through your weak interface? Well, thanks to Jim Odom, his team of engineers, and lots of jambalaya, PreSonus has designed the HP4 with 150 mW individual headphone amps. These amps are loud enough for live and session use, and they’re loud enough to explode the oysters in a Po’ Boy sandwich. Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to hear — assuming they are capable of hearing. Be careful with that level control!

As with other Max Rack products, simplicity is the hallmark of 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.

Like other processors in our Max Rack series, the HP4 can sit on a tabletop or can be mounted in 1/3 rackspace, using the optional 3UMR rack adapter. If your needs expand, 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!

Quit struggling with mediocre headphone amps. Get the HP4 and hear everything loud and clear. You owe it to your music.
