The M-864D is a user friendly rack-mountable digital stereo mixer suitable as a stage manager's mixer in performance venues or as a main mixer for educational or boardroom use. Three user interfaces are available- Front Panel operation, PC control by a Windows PC, or iPad control for a simplified interface. The M-864D accepts TOA 9000 series RS-485 remote controls, contact closure inputs and outputs to trigger presets, etc. and TCP/IP control, making it especially useful in projects that include room combining. Eight mic/line inputs and two groups of three stereo line level inputs are routable to any output by the onboard matrix. DSP includes Feedback Reduction, Automatic Resonance Control, and parametric equalization. Front panel controls may be disabled in software as required.
