OVERVIEW

Professional recording quality, desktop size.

The PreSonus HP4 Discrete 4-Channel Headphone Amp features 4 headphone outputs on the front panel, each with its own volume, and 150mW of amplification per channel-extremely loud output with a low -98dB noise floor. It also allows control over control room monitors with a separate volume knob that can be muted using the Monitor Mute button. 1/3 rackspace. Accepts balanced/unbalanced inputs and outputs (1/4" TRS). Input can either be set to stereo or mono (the mono selector button on the front channel simply copies both inputs to both sides). Powered by an external wall-mounted supply.

The HP4 represents a tremendous value as echoed by this email received by PreSonus:

"To my amazement, your HP4 sounded as good as both of my hi-fi stereo heaphone amps. Very very clean and loud. I can't believe you put 150 mw per channel, @52 ohms, to four headphone outputs and offer such a quality unit for very little over $100." (M. Burke via email)

FEATURES
  • 4 discrete headphone outputs
  • Each with its own volume and 150mW of power
  • Extremely loud output with low noise (-98dB noise floor)
  • Allows control over control room monitors with a separate volume knob
  • Control room volume can be muted using the Monitor Mute button
  • 1/3 rackspace
  • Balanced/unbalanced TRS I/O

Think small and get big-time headphone control.

      Revamping the studio into more of an Indie-level multimedia production facility for an Indie-level record label, I found myself needing additional headphone channels, and more control over my monitors. This solid as a rock, all-metal unit was exactly what I needed! Crystal clear sound, TONS of headroom, and that all important "monitor mute" button! I'd buy it again in a heartbeat!~M

      First one I got was defective. There was no increase in volume after the 12-o?clock position. Second one worked. The salesman told me that this amp would be loud enough for a drummers headphone mix during recording. Not true and not even close. It does provide decent sound but my stereo amp that we still use for recording drums, sounds better and is louder. I would not recommend this for those who need the headphone mix loud, but at low to moderate levels this is probably as good as other brands in this price range.

      Just a great product. This amp is super quiet. I was using a Behringer HA400 and it was way too noisey. Try it out and you won't be disappointed.

      Static sensitive = Fried

      By Blind Howard

      from Alaska

      Comments about PreSonus HP4 Discrete 4-Channel Headphone Amp:

      2000 model HP4 with metal knobs - new ones look to be plastic.
      Got up from monitoring chair - resultant static took HP4 out instantly (with very loud and potentially equipment damaging noises) when touching metal control knob. Electronics apparently not isolated to prevent same.
      Too bad I did not register mine - necessary for any tech support.

        I had experience with the HP4 in a friends studio so when I expanded mine I installed the HP4. It is easy to use, set up is a snap, the manual is simple to understand, global + 4 independent volume controls and monitor mute are all great and easily accessable features. It also has great looks and a great price point for the home recording studio.

        Each one of our 6 musicians/singers in our Kids Band at our church has one on their own mix. Having these allows our trainee/backup musicians to plug in and listen to rehearsals, click, talkback, etc. Very easy to use, and you can't beat the price.

        Died

        Comments about PreSonus HP4 Discrete 4-Channel Headphone Amp:

        I gave it a 2 because when it did work I really liked it.
        After a year it started to go in and out and finally I just can't use it any more. One side is dead. If you buy this one make sure you get the extended waranty, you most likely are going to need it. I didn't and I don't know if it is even worth seeing if they would fix a 1 1/2 year old amp.
        No value in undependable equipment.

        WOW! Turn it down!

        By Rick

        from Minnesota

        Comments about PreSonus HP4 Discrete 4-Channel Headphone Amp:

        Well I plugged it into my headphone jack on my pc speakers and started a playback. I had the units volume at about 10:00 and it nearly pierced my ears. I turned down the powered speaker volume and it was still too loud so I turned the unit down to a fraction above off and that worked fine. I don't yet have the right wire for plugging into a line out instead but I'm sure that will be loud enough also.

        Crystal clear but thin and tiring sound

        By Tasos98

        from Greece

        Comments about PreSonus HP4 Discrete 4-Channel Headphone Amp:

        I bought it as an an alternative choice of a double priced tube head amp to drive my Senheiser HD-650. The sound is very-very clear. I can hear whether the dust cover of my turntable is closed or open.BUT: The sound is very tiring. I admit I don 't like the "proffesonal sound" and this one "scratches" my ears. Furthermore, the sound stage is not placed above your head (as tit should be) but stuck right inside it (which is annoyng for may tastes).However is perfect for listening to old and warn-out vinyl records. Its analytic character adds some "air" to the sound and it makes them more listenable.I don't know if I could bye a better one at that price but I 'm looking forward to replace it with a pricier one.

        Comments about PreSonus HP4 Discrete 4-Channel Headphone Amp:

        4 very clean, very powerful channels, and any one of them is worth the price. Every bit as good as I have come to expect from Presonus.
