The PreSonus® HP4 headphone distribution system is louder than you'll probably ever need for session and stage use. (Be careful with that level control!) Yet the sound is clean and clear, with a wide dynamic range. Finally, everyone can hear! Simplicity is the hallmark of the HP4. It offers left and right line inputs, left and right line outputs with level control, and four headphone outputs. You can sum the stereo signals to mono, adjust individual headphone levels, and mute the rear-panel Monitor outputs while leaving the headphone outputs active. So while the HP4 is simple to set up and use, it has all the features you need to create a versatile headphone system. The compact HP4 can be placed on a tabletop or it can be screw-mounted to a standard rack tray (not included), where it takes up only one-third of a rack space. If your needs grow, you can use the line outputs to feed the inputs of a second HP4 headphone amp or the larger HP60 headphone amp. So stop struggling with mediocre headphone amps. Get a PreSonus HP4 and hear everything loud and clear. You owe it to your music. 4 loud (130 mW per channel) ¼-inch stereo headphone outputs (front panel) 2 balanced ¼-inch line outputs (monitor outputs) 2 balanced ¼-inch line inputs Headphone level control for each channel Mono summing switch for each channel Monitor level control and mute switch Daisy-chain multiple units via the monitor outputs Compact 1\/3U rack-mountable chassis Sealed, detented metal rotary controls External 16 VAC power supply\u003c\/p\u003e","brand":"Presonus","offers":[{"title":"Default Title","offer_id":53993324314957,"sku":"2777406203","price":129.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/206146-large_default.jpg?v=1779916799","url":"https:\/\/musicdelivery.net\/en\/products\/presonus-hp4-amplificatore-per-cuffie-4-canali","provider":"Music Delivery","version":"1.0","type":"link"}
