7.7.4 Input Signal Router
Each channel of the I-Tech’s signal processing has an Input Signal Router that
lets you choose the audio signal that will be used by the channel. Choose one
of the following configurations:
• Analog Audio: This is the audio input from the audio connector on the
back panel of the amp. Choices for the Analog Audio input are Channel 1,
Channel 2, or a sum of Channels 1, 2, 3, 4, or a sum of 3 and 4.
• Digital Audio: This is the audio input from the AES/EBU connectors or
CobraNet connector on the back panel of the amp. It can be set up for Digital
with Analog Backup or Digital with Analog Override:
• Digital with Analog Backup
The input takes the digital signal as its source when the digital signal (or just
the digital clock) is present. If the digital lock is lost, the input switches to the
selected Analog Source. Once that digital lock is found again, the input
switches back to the selected digital source. This works even when the digital
signal has no audio but is sending a clock signal.
• Digital with Analog Override
The input takes the digital signal as its source. If the analog signal level is
greater than an Analog Signal Detect Threshold that the user defines, the input
switches to the analog signal. As long as the analog signal level exceeds the
threshold, or as long as its level falls below threshold for a user-defined hold
time, the input remains the analog signal.
Analog Signal Detect Threshold (-100 dB to 0 dB)
This option is not displayed unless override is selected. If the selected analog
signal exceeds the threshold level, the analog signal becomes the source for
this input rather than the selected digital input source. Use the numeric spin
box or the fader provided to set the threshold.
Hold Time (0 - 60 seconds)
This option is not displayed unless override is selected. Once an overriding
analog input signal falls below threshold, the Hold Time determines how long
the input will continue to be the selected analog input before reverting to the
selected digital input. Use the numeric spin box or the fader provided to set this
time.
The control operation will vary based on the mode that is selected.
