The PreSonus® HP4 headphone-distribution system is louder than you're ever likely to need for session and stage use. (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!\u003c\/p\u003e\n\u003cp\u003eSimplicity is the HP4's hallmark. It offers left and right line inputs, left and right line outputs with level control, and 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 HP4 is simple to set up and use, it has all the features you need to create a versatile headphone system.\u003c\/p\u003e\n\u003ch3 class=\"product-content-features__heading product-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4 screaming-loud (130 mW per channel) stereo ¼-inch headphone outputs (front panel)\u003c\/li\u003e\n\u003cli\u003e2 balanced ¼-inch line outputs (monitor outputs)\u003c\/li\u003e\n\u003cli\u003e2 balanced ¼-inch line inputs\u003c\/li\u003e\n\u003cli\u003eHeadphone level control for each channel\u003c\/li\u003e\n\u003cli\u003eMono summing switch for each channel\u003c\/li\u003e\n\u003cli\u003eMonitor level control and mute switch\u003c\/li\u003e\n\u003cli\u003eDaisy-chain multiple units via monitor outputs\u003c\/li\u003e\n\u003cli\u003eCompact 1\/3U rack-mount chassis\u003c\/li\u003e\n\u003cli\u003eSealed, detented, metal rotary controls\u003c\/li\u003e\n\u003cli\u003eExternal 16 VAC power supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSPECS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"product-specs-heading\"\u003eVoltageRequirements: 100-240 VAC, 50-60 Hz\u003c\/li\u003e\n\u003cli class=\"product-specs-heading\"\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Blue\u003c\/li\u003e\n\u003cli class=\"product-specs-heading\"\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e HP4 4-Channel Headphone Amplifier, Blue, 120V NA\u003c\/li\u003e\n\u003cli class=\"product-specs-heading\"\u003e\n\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eHeadphone Amplifier Input Connection Type:\u003c\/strong\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e 1\/4\" TRS, Balanced\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli class=\"product-specs-heading\"\u003e\n\u003cstrong\u003eHeadphone Amplifier Input Frequency Response:\u003c\/strong\u003e 20 Hz to 20 kHz, +\/-0.5 dB\u003c\/li\u003e\n\u003cli class=\"product-specs-heading\"\u003e\n\u003cstrong\u003eHeadphone Amplifier Input Impedance: \u003c\/strong\u003e10 kΩ\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eHeadphone Amplifier Input Maximum Input Level:\u003c\/strong\u003e +18 dBu, \u0026lt;0.5% THD+N, unity gain\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eHeadphone Amplifier Input Total Harmonic Distortion:\u003c\/strong\u003e 0.0025%, 1 kHz, unity gain\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eHeadphone Outputs Frequency Response:\u003c\/strong\u003e 20 Hz - 20 kHz, ±0.5 dB, 60Ω Load\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eHeadphone Outputs Impedance Working Range:\u003c\/strong\u003e 32Ω to 600Ω\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eHeadphone Outputs Maximum Output: \u003c\/strong\u003e130 mW\/Ch., \u0026lt;0.5% THD+N, 60Ω load\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eMonitor Output Connection Type:\u003c\/strong\u003e 1\/4\" TRS, Balanced\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eMonitor Output Impedance:\u003c\/strong\u003e 51Ω\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-heading\"\u003e\u003cstrong\u003eMonitor Output Maximum Output Level:\u003c\/strong\u003e +18 dBu, \u0026lt;0.5% THD+N\u003c\/p\u003e\n\u003cdiv class=\"product-specs-props\"\u003e\n\u003cp class=\"product-specs-content\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fender","offers":[{"title":"Default Title","offer_id":51935624790318,"sku":"HP4","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0262\/5988\/2093\/files\/2777400203_pre_amp_frt_1_nr.png?v=1775511847","url":"https:\/\/www.cbnmusicwarehouse.com\/products\/presonus-hp4-4-channel-headphone-amplifier","provider":"CBN Music Warehouse","version":"1.0","type":"link"}
