Overview

Let the band members hear each other and themselves.

This pack includes the Presonus HP4 Discrete 4-Channel Headphone Amp, and two AKG K77 Headphones.

Presonus HP4 Discrete 4-Channel Headphone Amp

The PreSonus HP4 Headphone Amp features 4 headphone outputs on the front panel, each with its own volume, and 150mW of amplification per channel-extremely loud output with a low -98dB noise floor. It also allows control over control room monitors with a separate volume knob that can be muted using the Monitor Mute button. 1/3 rackspace. The Presonus amp accepts balanced/unbalanced inputs and outputs (1/4" TRS). Input can either be set to stereo or mono (the mono selector button on the front channel simply copies both inputs to both sides). Powered by an external wall-mounted supply.

AKG K77 Headphones

AKG K77 headphones are all-round closed-back performers with solid bass and clean highs. AKG K77 headphones offer you dynamic around-ear sound quality that is perfect for home studios and listening enjoyment. The AKG headphones include comfortable leatherette earpads that allow for extended wear. You get a very accurate listening experience, thanks to an 18Hz-20kHz frequency range. If you perform a lot of desktop recording, engage in late-night rehearsing, or just want to plug into an MP3 player, then these headphones are ideal for you.
