The HP4 from PreSonus answers the project studio owner's needs for headphone distribution with professional specifications and more in a small package with an affordable price. The unit comes in a 1/3-rackspace chassis similar to the TubePre. The HP4 accepts balanced/unbalanced inputs and outputs (1/4" TRS). The input can either be set to stereo or mono. The mono selector button on the front channel simply copies both inputs to both sides. Even a small project studio can benefit from having an HP4 on hand!Ideal for a modular setup with PreSonus' other popular compact units (TubePre, Comp16, and EQ3B), the HP4 comes packed into a 1/3-rackspace chassis that's super-efficient, durable, and frankly, cool-looking. And its diminuitive size is deceptive: you get an incredible amount of functionality and versatility out of this unit, making it perfect for your individual setup!
