15.1.1. [Ch A]–[Ch H] of [Input Source Redundancy]

This will be [Ch A]–[Ch D] for four-channel models.
Here you can specify for each channel whether the input source to the XMV will be digital or analog. If the input source is specified as digital, you can specify that the input source will switch from digital to analog when a pilot tone or analog input is detected. Here we explain the screen for when the digital input is Dante.
When you click the […​] button, the "Input Source & Redundancy" dialog box appears.

    • [Backup]
      Switch to analog input when the pilot tone of the digital input is interrupted due to a broken connection or other problem.

    • [Override]
      Switch to the analog input when analog audio is detected.

  • [Auto Return] check box
    If this check box is selected, operation will be as follows.

    • In the case of Backup mode
      When the digital input recovers, the input source is switched from analog to digital.

    • In the case of Override mode
      When the analog input falls below the threshold value, the input source is returned from analog to digital.

  • Channel index
    Shows the input channel number for which to make settings.

  • "Primary Input Source" area
    Here you can specify for each channel whether the input will be digital or analog.

    • [YDIF (Digital)]/[Dante (Digital)] option button
      The signal of the corresponding channel is taken from YDIF or Dante.
      To specify the Dante patching, make settings in Dante Controller.

    • [Active Redundant Mode] check box
      If this check box is selected, the redundancy function is enabled.
      The [Redundant Mode] list box determines the redundancy mode. If [Off] is selected, the redundancy function is disabled even if this check box is selected.

    • [Analog] option button
      The signal is taken from the analog input jack of the corresponding channel.

  • "Redundant Mode - Backup" area
    Here you can specify how the pilot tone is detected for each channel.

    • [Frequency] spin box
      Specifies the center frequency of the pilot tone.

    • [Detection Threshold] spin box
      Specifies the input level threshold value for the pilot tone. Input that exceeds the threshold value is considered to be the pilot tone.

      • [Detection Time] spin box*
        Specifies the detection time for the pilot tone. If the pilot tone can not be detected for the specified time interval, it is determined that the input has ceased.

      • [Notch Filter] check box*
        If this check box is selected, a notch filter is enabled to eliminate the frequency component of the pilot tone so that the pilot tone is not output from the amp.

    • [Q] spin box
      Specifies the width of the frequency band for the notch filter.

  • "Redundant Mode - Override" area
    Here you can specify the conditions under which each channel will switch to the analog input in Override mode.

    • [Override Threshold] spin box
      Specifies the threshold value for the analog input. When the threshold value is exceeded, the input source will switch to analog.

    • [Auto Return Delay] spin box
      If the [Auto Return] check box is selected, this specifies the time after the analog input falls below the threshold value until the input is switched back to the digital input.

  • [Save Changes] button
    Saves the settings and closes the dialog box.

  • [Cancel] button
    Discards the changes and closes the dialog box.
