The ART HeadAmp4Pro could be the most fully featured ultra compact headphone amplifier in its price point on the market today.
Packing as many features as possible into the small format chassis, the HeadAmp4Pro has five stereo headphone outs, each with their own volume control. A separate footswitchable XLR input (with phantom power) allows instant talkback to any one, or all of the connected headphones. Input matrix allows the listener to audition any or all auxiliary inputs for maximum versatility.
Although designed for home and project studio, the HeadAmp4Pro may easily be the ideal solution for teaching stations and conferencing communication networks.
