PreSonus HP4

features 4 headphone outputs on the front panel, each with PreSonus HP4's own volume, and 150mW of amplification per channel-extremely loud output with a low -98dB noise floor. The HP4 answers the project studio owner's needs for headphone distribution with professional specifications and more in a small package with an affordable price. PreSonus HP4 also allows control over control room monitors with a separate volume knob that can be muted using the Monitor Mute button. PreSonus HP4 comes in a 1/3-rackspace chassis similar to the TubePre. The HP4 accepts balanced/unbalanced inputs and outputs (1/4" TRS). PreSonus HP4 is 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.
