Toa Electronics M-864D Digital Stereo Mixer

The Toa Electronics M-864D Digital Stereo Mixeris a 4U rack mountable digital stereo mixer with 8 monaural mic/line input channels, 7 stereo input channels, and 6 output channels, including 4 bus-assignable monaural output channels and 1 stereo recording output channel.

The unit is equipped with digital signal processing functions such as automatic resonance control, feedback suppressor (FBS), automatic stereo input mute function (AUTO MUTE or Ducker), and equalizer. Advanced acoustic compensation can be automatically performed without using an acoustic measuring instrument. Furnished with various function-setting buttons and 14 analog volume faders, the M-864D can be operated without the need or use of a PC. However, it can also be operated by connecting the PC or optional Remote control panel, and can be mounted in an EIA standard component rack (4U size).

Automatic Resonance Control function automatically creates an appropriate equalization curve based on measuring the acoustic characteristics inherent in an architectural space, thus improving sound clarity

The Feedback Suppressor (FBS) eliminates feedback from microphones that are moved to multiple locations

Automatically mutes the stereo input when monaural signals are detected
