Description
The MMA 800T is a high-quality‚ industrial-grade audio mixer/preamp with nine input
channels. Each channel provides a level control, and the master output section features bass
and treble EQ controls (defeatable) and special equalization contour.
The MMA 800T provides unmatched application flexibility and an array of optional plug-in
modules, allowing each system to be tailored to specialized installations. Input modules may
be loaded as required for varying sound reinforcement applications (number of input channels,
special functions, etc).
The program input includes a level control and is totally separate from the other eight
channels. External signals may be patched in at this point as a system auxiliary input or
the ninth input channel. Signals appearing at this input are routed directly to the master
summing amplifier stage and are mixed with signals from the other eight channels. Systems
requiring a single input may use the program input—making the purchase of an input module
unnecessary. The program level control regulates the level of this input and the signal is
routed through the system bass and treble controls.
The MMA 800T is packaged as a stand-alone unit but will also mount into a standard 19" rack
with an optional rack-mount kit.
