Digital Outputs; Digital Syncronisation - Focusrite OctoPre MkII User Manual

Digital Outputs

Use the ADAT output(s) to connect the OctoPre MkII to the ADAT input(s) of any analogue device.
The OctoPre MkII will send 8 channels of audio @ 44.1 / 48kHz via a single optical cable. The same 8 channels is sent out of both
optical ports.
The OctoPre MkII will send 4 channels of audio @ 88.2 / 96kHz via a single optical cable. Channels 1-4 and 5-8 are sent out of each
optical port.
Use the Sample Rate to select the desired sample rate. You must ensure that the sample rate selected on the OctoPre MkII matches
the sample rate set on the receiving digital device.
Digital Synchronisation
There are two synchronisation options available:
OctoPre MkII as Clock Source Master:
Connect the OctoPre MkII to the digital device via ADAT and ensure that the receiving device is set to receive clock from the ADAT
input (also ensuring the sample rates on both devices are matched).
The OctoPre MkII Clock Source should be set to Internal and the Locked LED will light up Green.
OctoPre MkII as Clock Source Slave:
Connect the OctoPre MkII to the digital device via ADAT and connect a BNC cable (from the receiving device or any other device in the
digital chain) to the Word Clock input (also ensuring the sample rates on both devices are matched).
The OctoPre MkII Clock Source should be set to Word Clock and the Locked LED will light up Green.
