Configure Digital Inputs

The MVC 121 Plus has three digital input ports located on the rear panel. The default state of the digital input is logic Hi (not shorted), with no assigned actions (off). Configuration of these ports is performed only through DSP Configurator, either in Live or Emulate mode. Digital input configuration settings are saved with the configuration file.

Configuring a Digital Input

Each digital input port can be configured to perform the following function:

  • No Action/Off — The port is "off," or not configured. This is the default.

  • Mute/Unmute — The mix-point mute state is toggled from mute to unmute. The functionality is fixed such that:

  • Digital input port #1 mutes Mix-point 1

  • Digital input port #2 mutes Mix-point 2

  • Digital input port #3 mutes Mix-point 3

There are several ways in which the functions can be triggered:

  • Not Configured — Digital Inputs are not being monitored.

  • Edge - Hi to Lo — Triggers a function when the port transitions from a Hi to Lo state.

  • Edge - Lo to Hi — Triggers a function when the port transitions from a Lo to Hi state.

  • Level - Lo —  Triggers a function when the port is in a Lo state.

  • Level - Hi — Triggers a function when the port is in a Hi state.

Combinations of functions and triggers result in specific behaviors, as follows:
