Housed in a convenient 2U package, the MA6.8Q 4-channel amplifier
allows for the adjustment of maximum voltage peak, gain adjustment
and has on-board network capability for monitoring and control. With
these features it is now possible to specify identical amplifiers in an
installation and then adjust each output to the very specific requirements
of the speaker system. A typical large-scale system is a combination of
high-powered speakers, full range in-fill speakers, 70/100V ceiling
speakers, with an active speaker management system. With switchable
outputs and on-board network capabilities, the MA6.8Q can be
designed into a complete value engineered system handling all
amplification tasks.
