w Input Redundancy
You can enable audio network redundancy for use with analog input signal(s) and digital input signal(s).
 Auto Return
If this check box is selected, operation returns to the digital input automatically.
Redundant Backup: Returns to the digital input when the pilot tone is detected.
Redundant Override: Returns to the digital input when the analog input falls below the specified
level.
 Channel selection
Here you can select the amp channel which you want to make settings.
 Redundancy Enabled
If this check box is selected, the redundancy function is enabled for each amp channel.
 Backup : Pilot Tone
Here you can make settings for the pilot tone which is used on Backup mode.
Frequency: Here you can specify the center frequency of the pilot tone.
Detection Threshold: Here you can specify the threshold value for the pilot tone level.
Detection Time: Here you can specify the pilot tone detection interval.
If the pilot tone was not detected within the specified time interval, it will be
determined that the input has been interrupted.
Notch Filter: When selected, this enables the notch filter that eliminates the frequency component
of the pilot tone so that the pilot tone will not be output by the amplifier.
Q: Here you can specify the width of the notch filter's frequency band.
 Override
Here you can make detailed settings in the Override mode.
Override Threshold: Here you can specify the input signal level at which digital input is switched
to analog input.
Auto Return Delay: Here you can specify the time from when the analog input falls below the
specified level until the signal is switched to the digital input.
Mode Content
Off Input redundancy function is off.
Redundant Backup
The input switches automatically from digital (for main input) to analog (for
backup input) when the pilot tone of a digital input is interrupted.
Redundant Override
The input switches automatically from digital to analog when the analog input
reaches the specified level or higher. You can specify the threshold level at
Override Threshold in the Override field.
