● Input Redundancy
Here you can make settings for a redundant connection (duplicate audio connections) that uses both the analog input signal and
the digital (slot) input signal. If the digital input audio is interrupted by a broken connection or other problem, the amplifier can
automatically switch to the analog input (Backup), or the amplifier can automatically switch to the analog input simply when an
analog audio input signal is detected (Override).
■ Signal Path
Refer to the “SIGNAL PATH Screen” (page 30).
Parameter name Range Explanation
Mode OFF, Backup,
Override
Specifies the redundant connection mode.
Backup : The input signal from the card installed in the slot will be the main signal; if the
input from the card becomes unlocked, the amplifier will automatically switch
to the input from the analog jack. Refer to “Supported I/O cards” (page 9) to
check if your I/O card supports the Backup mode.
Override : The input signal from the card installed in the slot will be the main signal; if
input from the analog jack is detected, the amplifier will automatically switch to
the input from the analog jack.
Auto Return ON/OFF When using Backup mode, this specifies whether the slot input will be re-enabled when the
interrupted slot input has recovered.
When using Override mode, this specifies whether the slot input will be re-enabled when the
analog input is interrupted.
Ovrrid Ch Link ON/OFF When using Override mode, this specifies whether both channels will switch together (ON) or
separately (OFF) when analog input is detected as being present or absent.
Ovrrid Thrsld -30.0–0.0 dBFS When using Override mode, this specifies the input level threshold value used to determine
the presence or absence of analog input.
Auto Rtn Delay 0–60 s When using Override mode with Auto Return ON, this specifies the time from when an inter-
ruption in the analog input is detected until the amplifier switches to the digital input.

Both of the analog and digital signals are
