7.4. INPUT REDUNDANCY
The PC-D/DI series has two types of redundancy function as appropriate for the situation: "backup mode" and
"override mode."
NOTE
• The INPUT REDUNDANCY function is independent of the Dante network’s redundancy function.
・Backup mode
This automatically switches to a backup circuit if the Dante input audio is interrupted due to a problem such as a
malfunctioning input device (BACKUP). Subsequently, if the input audio is restored, the unit can automatically
return to the original circuit.
The backup circuit can be specified in two levels.
Dante In (1-4) is the primary (main circuit), Dante In (13-16) is used as Second (2nd SOURCE), and Analog In (1-4)
is used as Third (3rd SOURCE). The channel combinations are fixed.
Primary 2nd SOURCE 3rd SOURCE
Dante IN 1 Dante IN 13 Analog IN 1
Dante IN 2 Dante IN 14 Analog IN 2
Dante IN 3 Dante IN 15 Analog IN 3
Dante IN 4 Dante IN 16 Analog IN 4
・Override mode
If audio input is detected from Dante input (13–16) jacks or from the analog input jacks, the detected signal will
automatically interrupt (OVERRIDE) the audio of the normally-used Dante inputs (1–4). This allows a high-priority
emergency broadcast or an in-building announcement to be broadcast as an interrupt.
■ COMMON page
① MODE (Redundant Mode)
This specifies the redundant function mode.
BACKUP: The input signal from Dante 1-4 is the primary (main circuit), and when the input from Dante 1-4 is
interrupted, the unit automatically switches to the audio from Dante 13-16 or the analog input jacks.
OVERRIDE: The input signal from Dante 1-4 is the main circuit, and automatic switching occurs only when high-
priority audio is detected.
② AUTO RETURN
For BACKUP mode:
If this is ON, the input source returns to the main circuit when the main circuit recovers.
For OVERRIDE mode:
If this is ON, the input source returns to the main circuit when the audio from Dante 13–16 or the analog input
jacks falls below the threshold value.
