Digital Mixer TOA D-901
-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.
