TOA D-901 audio mixer 12 channels 20 - 20000 Hz Black

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. Digital mixer with up to 12 inputs and 8 outputs. Module base frame with rear slots for various input and output modules for flexible expansion of the system according to the requirements. Feedback suppressors with 12 filters in automatic or dynamic mode. Automatic mixer with variable NOM-(number of open microphones) and ducker functions (signal-controlled mute) with 8 priority levels. DSP functions of the input channels: trim (gain), pad, attenuator, phase reversal, compressor, variable high-pass filter, 2 parametric equalizer DSP functions of the output channels: mixing matrix, attenuator, delay up to 682,6 ms, compressor, 2-, 3-, 4-way crossover network with filter slopes up to 24 dB/octave and different characteristics (Bessel, Butterworth, Linwitz-Rayley and variable Q) or 6 multifunction filters with selectable filter types parametric equalizer, high-pass, low-pass, all-pass filter, notch-filter, shelv-filters for bass and treble, CD-Horn equalization. 16 preset configurations can be stored in the device independent of the mains and recalled via keypad or remote control, 8 configurations directly available via front panel buttons. All settings possible without PC software via front panel controls with the help of 2-line LCD. Quick direct access to the level settings and on / off switch and signal indicator for each input and output channel. Access lock on front panel controls individually adjustable. Software: Configuration and all parameters can be saved to disk; Display of amplitude, phase and elapsed time frequency response; Stereo and universal parameter links; Access lock in 3 levels for each DSP function, inputs, output. Name assignment to configurations and device for a better overview. In real time mode display of the signal level of the inputs and outputs. Programming of remote control parameters. Possibility of a simple remote control for the configuration selection, mute, and volume control with control input module. Easy control of the system by AMX, Crestron, cue, and other similar units by simply held protocol via RS232C interface.
