Product Description

The PreSonus HP4 answers the need for a headphone distribution amplifier with professional specifications in a small package at an affordable price. The HP4 features four discrete headphone outputs on the front panel each with its own volume potentiometer and 150mW of amplification per channel. The HP4 also features adjustment over control room monitors with a separate volume control, monitor mute switch and mono switch giving you an extremely powerful monitoring solution at an amazingly low price.

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)

Product Review

I have had this guy for a little over a month now and it has proven itself as a worthy addition to my rig. The amp feels very nice in terms of build quality. Some of the edges aren't as smooth as they could be but not a big deal. The dials are smooth with the smallest of movements making a big difference in volume. The signal quality is excellent with no discernible coloration to the sound. It also delivers enough power to drive my HD 650's. The pass-through to my monitors is the main reason I bought this plus the ability to have multiple headphone listeners. Great buy. Definitely recommend.

Great, Simple Unit

Your general opinion of this product.

It's a good, simple handy unit for me to have. Even though I mostly record my own tracks, I use this device to plug in several different headphones so I can work on different mixes: my top-of-the-line headphones, my middle-of-the-road headphones, and my mediocre ones.

It has a decently rugged feel.

Very easy to use.

I love the monmix button.

Yes. Four outputs is all I need. It's nice to have an option other than the 8 port, rackmount units.

Monitor mute is worth the price alone

Seems like a well built little unit.

4 headphone inputs. I bought it because I wanted a headphone amp as my multitracker was a little low in volume. BUT the big selling point of this is the ability to put this between your source and monitors and have the ability to mute or control the volume of your monitors, alot easier than reaching behind 2 krk rokit 6's and adjusting the volume...For this alone it is worth the money.

So easy a caveman could use it!

Great value...I would rather see it at about $100

I love this unit

Seems to be built like a tank.

For what it does, it has some nice features.

Great value.

perfect unit

presonus makes well built stuff- this feels like it's well built even though it's pretty low cost

the monitor pass-thru is extremely useful- i'm feeding it into a second pair of monitors to compare mixes

extremely idiot proof

Yup- the output to the headphones is great- adds a whole new level of flexibility to the tracking environment

Buy it. You won't go wrong.

Your general opinion of this product.

Extremely wel built. You have no cosmetic and integrity concerns when buying this piece

I wanted something that would not color sounds passing from the headphones to my ear. This is the device to achieve that. One knob per channel. I do not need EQ to come with my headphone amp. I need it to boost signal and it does that in spades.

As I said, each channel has a single knob. Nuff said.

Price to quality ratio is plain funny. For $100, you get an excellent, uncolored boost in headphone signal. Period.

No coloring at any volume.
