What makes the unit really powerful are the typical broadcast logical functions:

  • Red light signaling for Studio and Control Room,
  • Remote recall of stored settings also by means of a simple external switch.

And for each channel:

  • Faderstart, continue or pulse; “Start” on/off button; Pfl. active output; Enable codec / hybrid output (hybrid 'on');
  • Channel remote mute input; Ring detect input to signal incoming calls from hybrids;
  • Fader overrule (unity gain e.g. for automatic commercial broadcast); Remote pfl. 'on');
  • In order to integrate the mixing desk with broadcast automation software all these functions are available on a USB connector.

Logic controls are available on 3 pcs. 25 pin D-type connector -with 8 general purpose opto isolated- outputs and 8 inputs each. You can program a choice or a combination of the above functions to these inputs and outputs.

All settings can be stored into and recalled from non volatile memory, also available is a mode were you can remote recall previously stored settings by means of a simple contact closure. Selectable mode of operation at start-up.
