4.8.4 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 confi gurations:

•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 and 2.

•Digital Audio: This is the audio input from the AES/EBU connector 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 defi nes, 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-defi ned 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.
