The analog inputs for the DriveCore Install Netowrk amplifier provide additional flexibility when for the BLU Link digital audio bus. From the BLU Link Output Configuration
window (Input Icon >Source Routing > BLU Link Output Configuration), it is possible to utilize the DCI-N amplifier to be a BLU Link On-Ramp in two different ways:
Send unprocessed audio from the analog inputs of the amplifier to 1 of the 8 available BLU Link outputs
NOTE: The audio from the analog inputs passes though the amplifier input gain stage (affected by selecting 28dB or 34dB of gain), and then through the input trim
and polarity switches in the Source Routing - Input Configuration panel, before being sent to the BLU Link bus.
Send post-processing audio from a DCI-N amp channel to 1 of the 8 available BLU Link outputs
NOTE: The post-processing audio is bussed from a point at the end of the entire channel processing chain in the DCI-N. This is effectively analogous to taking
the audio from the physical output of the amplifier feeding a loudspeaker, and routing it onto the BLU Link network.
After selecting an Audio Source in the dialogue shown above, double-click on the BLU Link Routing button. It is absolutely necessary to take this additional step, which
allows the 8 BLU-Link output slots inside DCI-N to then be routed onto one of the slots available on the larger BLU Link audio ring.
NOTE - BLU LINK OUTPUTS (ON-RAMP FROM DCiN TO BLU LINK ) ARE DISABLED WHEN THE BLU LINK NETWORK IS OPERATING AT 96KHZ SAMPLING RATE
When attached to a BLU Link network running at 96khz, DCI-N will not be usable as an on-ramp. The amplifier will be able to receive a full compliment of up to 8 streams
to send to the input router, but it will not be able to send any analog or post-processing audio signals back onto the Blulink network.
See the section on BLU Link Settings for more information about operation at different sample rates, mastership priority, and for more help on BLU Link audio.
