The MH-8 from Tascam is a professional-quality rackmount headphone amplifier that allows 8 listeners to monitor a variety of sources. Each of the 8 channels has its own direct stereo input. There are also 2 stereo channels that can be shared to any of the outputs. Each 1 4 headphone output can select one input, or mix several together. All of the outputs have an individual level control, as well as input selector switches, a mono switch, and signal and overload LED indicators. A set of 4 TRS foldback outputs allow you to daisy-chain multiple units.
