PreSonus Audio Electronics Inc. (Baton Rouge, La.) is now shipping its HP4, a compact headphone-distribution solution. Featuring four discrete headphone outputs on the front panel, its own volume potentiometer and 250 mW of amplification per channel, the unit produces a very high output while maintaining low noise.
The HP4 accepts balanced/unbalanced inputs (stereo or mono) and outputs (1/4-inch TRS), and has a Mono Selector button on the front channel that copies both inputs to both sides. The HP4 has a -98dB noise floor and wide frequency responses. It also provides an extra pair of TRS outputs that can be used to link multiple units and feed control-room monitors. The user can control the volume or mute the monitor speakers from the HP4's front panel when using up to four sets of headphones. It is externally powered by a wall-mounted power supply.
