Behringer HA400 4-Channel-Stereo-Headphone-Amplifier

The MICROAMP HA400 is an amazing Ultra-Compact 4-Channel Stereo Headphone Amplifier. If you're tracking more than one musician at once, or if everyone in a group wants to listen to a playback, you need a monitor distribution system. The compact, flexible HA400 can power up to 4 pairs of headphones and up to 4 independent volumes. Let up to 4 different people in your studio listen to the main mix while recording, and each listener can determine their own volume level using the output level controls.
