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)

Ease of Use
Monitor mute is worth the price alone
Would you consider this product to be made well? How dependable?
Seems like a well built little unit.
What do you consider to be the best features of this product? What features would you add to this product if you could?
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.
Ease of Use
How easy is this product to use? How easy is the product to use with other products? Did it take long for you to learn to use this product? Was the manual helpful? How playable do you consider this product to be?
So easy a caveman could use it!
Was this item an overall good value?
Great value...I would rather see it at about $100
