Quick OverviewHeadphone Amp Presonus HP4
Now Hear This!
Are you and your session players and bandmates tired of straining to hear underpowered headphones? We were too. Thats why Jim Odom and his jambalaya-fueled team of engineers designed 150 mW headphone amps for the HP4 headphone-distribution system. These headphone amps are not just loud enough for session and stage use, theyre 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 hearassuming 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. And if your needs grow, 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.
So listen up! Quit struggling with mediocre headphone amps. Get the HP4 and hear everything loud and clear. You owe it to your music.
