MISSION BRIEFING:

4-channel balanced headphone distribution including monitor volume, mute and mono switches in a 1/3 rack design.

MISSION DETAILS:

The Presonus HP4 comes in a 1/3-rackspace chassis similar to the TubePre. The HP4 accepts balanced/unbalanced inputs and outputs (1/4" TRS). It features four discrete headphone outputs on the front panel each with its own volume potentiometer and 250mW of amplification per channel. Can you say quiet? PreSonus can with the HP4's -98 dB noise floor and wide frequency response. Also, the HP4 allows control over control room monitors with a separate volume potentiometer that can be muted using the MONITOR MUTE button. The HP4 is powered by an external wall mounted power supply. 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.
