Input Signal Router
Each channel of the DriveCore Install signal processing has an Input
Signal Router that lets you choose the audio signal that will be used by
the channel.
• Analog Audio: This selection set up the input router for analog
sources. Each output channel will select its corresponding
analog input. Choices for the Analog Audio input are Channel 1,
Channel 2, or a sum of Channels 1 and 2. Selecting Analog only
will automatically change the MEDIUM input source to none.
• BLU Link Digital Audio: This is the audio input from the BLU
Link connector on the back panel of the amp. Each amplifier has
8 BLU Link input channels, plus 4 pairs of BLU Link summed
channels. This does not represent 1 - 256 but rather the BLU
Link input channels that have been selected for the amplifier.
• 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.
• Analog Overrides: BLU Link input takes the digital signal as its
source. If the analog signal level is greater than an Analog Signal
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
The control operation will vary based on the mode that is selected.
