Digital Mixer

The D-901 is a 19-type rack-mounted (3U high) digital mixer configured with 12 inputs, 8 buses, and 8 outputs. It features signal processing functions necessary for sound systems such as feedback suppression and auto-mixing. Modular construction permits flexible configuration of inputs and outputs, from 2-IN/4-OUT to 12-IN/8-OUT systems.
All functional parameters can be set at the unit. Settings can be stored in the unit's internal memory as "preset memory" and can be recalled using the front panel-mounted operation keys.

  • 12-input, 8-bus, 8-output channel configuration (12 x 8 matrix) with easy operation
  • Can be expanded as application requires
  • Convenient front panel controls and display make it easy to perform all functions and confirm
  • Parameter settings without requiring a PC
