Ultra-Compact 4-Channel Stereo Headphone Amplifier

MICROAMP HA400 If you're tracking more than one musician at a time, or if everyone in the group wants to listen to the playback, you’re need a monitor distribution system. A distribution system allows everyone to listen in, and control the volume of his or her own headphones. The compact and flexible HA400 can power up to 4 pairs of headphones and up to 4 independent volumes, with outstanding audio quality – even at maximum volume!
