HA400 MicroAMP

The Behringer MicroAMP HA400 is a compact four-channel stereo headphone amplifier designed to distribute a single stereo audio source to up to four pairs of headphones. Each output uses an independent amplifier section with its own Phones Level control, allowing four listeners to set their headphone volumes separately while monitoring the same source. The circuit uses low-noise 4580 operational amplifiers and is designed to work with a wide range of headphones while maintaining audio quality at higher output levels. The HA400 is intended for studio, recording and stage monitoring applications and is powered by the included 12V DC adapter.
