Product Overview
The ultimate headphone amplifier, TASCAM's MH-8 works great for use in studio, stage and installation applications...and more. Each of the unit's 8 stereo outputs achieves 250 mW per side with 3 available switchable sources. It has 2 stereo inputs that can be shared to any of the outputs, plus individual stereo direct inputs are also available for each of the 8 channels. A headphone out can select any one of these inputs, or mix several together. A set of foldback outputs allow you to chain other MH-8 units (sold separately) into a system.
