The Behringer MicroAMP HA400 is an ultra-compact, desktop-sized 4-channel stereo headphone distribution amplifier designed for studio monitoring, podcasting, and group rehearsals. It solves the common problem of an audio interface or mixer only having one headphone output by splitting a single audio source into four separate lines, allowing multiple people to listen at the same time.
Enclosed in a rugged, compact metal housing built to withstand portable studio use.
Features an LED power indicator light and four independent Level knobs to control the volume of each headphone output separately.
Outfitted with 4580 operational amplifiers (op-amps) intended to maintain clear audio performance and low noise even at maximum volume.
