Product Overview
The TOA M-864D is a 4U rack mountable digital stereo mixer that features 8 mono 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. It is equipped with Automatic Resonance Control (ARC) function which automatically creates an appropriate equalization curve based on measuring the acoustic characteristics inherent in an architectural space, thus improving sound clarity. The M-864D also features DPS functions such as Feedback Suppressor (FBS), Automatic stereo input mute (AUTO MUTE or Ducker) and Equalizer. Advanced acoustic compensation can be automatically performed without using an acoustic measuring instruments. 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. It can be mounted in an EIA standard component rack (4U size).
