Tascam MH-8
The Tascam MH-8 is the ideal headphones amplifier for studio, stage and installation. Each of the eight stereo outputs delivers 250 mW per side with three switchable sources available. Two stereo inputs can be shared to any of the outputs, and individual stereo direct inputs are available for each of the eight channels. A headphones channel can use any one of these inputs, or mix several together. And a set of foldback outputs allows the user to chain other MH-8s into a system.
The MH-8 is housed in a rugged, rack-mountable metal chassis with built-in power supply (no AC adapter), ground terminal and ground-lift switch for many years of safe and reliable operation.
