Tascam MH-8 Datasheet
PRODUCT OVERVIEW
MH-8
Technical Information
INTRODUCTION
TASCAM’s MH-8 is the ultimate headphone
amplier for studio, stage and installation. Each of
the eight stereo outputs gets 250mW per side with
three switchable sources available.
Two balanced stereo inputs can be shared to
any of the eight outputs. In addition, an individual
stereo direct input is available for each of the eight
output channels. A headphone out can select any
one of these inputs, or mix several together. A
mono switch is provided for simple one-ear headphone mixdowns, and a set of foldback outputs
allow you to chain other MH-8s into a system.
For the ultimate in routing exibility and power,
nothing beats the MH-8 headphone amp from
TASCAM.
