ART HeadAMP4 Eight Output Stereo Headphone Amplifier

The ART HeadAMP4 is a professional-grade stereo headphone amplifier designed to provide multiple listeners with high-quality audio from a single source. It features eight independent outputs across four stereo channels, making it ideal for studio monitoring, band practice, or collaborative listening sessions. The unit allows musicians, producers, or audio enthusiasts to share a mix without compromising on sound quality or imposing additional load on the original source device. The amplifier is housed in a durable, stackable extruded metal case and offers both 1/4-inch (6.35mm) and 1/8-inch (3.5mm) input and output connections, ensuring compatibility with a wide range of audio equipment. Each of the four channels has its own level control, allowing users to adjust volume independently for different headphones, including studio monitors, in-ear monitors, or consumer headphones. Technical specifications include a frequency response of 20Hz to 20kHz, a signal-to-noise ratio greater than 90dB, and total harmonic distortion of less than 0.01%, resulting in clean, accurate audio reproduction. This unit is particularly well-suited for home studios, project studios, rehearsal spaces, or educational environments where multiple people need to listen simultaneously. It works seamlessly with mixers, audio interfaces, digital audio workstations, portable media players, and laptops. The included 12V DC power adapter ensures reliable operation, while the compact dimensions make it easy to integrate into existing setups. Whether for critical listening, tracking, or simple audio sharing, the HeadAMP4 provides a practical and flexible solution for expanding headphone monitoring capabilities.
