Rednet 3 - Rear Panel - Focusrite RedNet 3 User Manual

6. CLOCK – One of five yellow LEDs will be illuminated to confirm the currently selected source
of clock for the RedNet 3 unit if it is currently selected as Preferred Master in RedNet Control.
The clock source is selected in software from RedNet Control, and the options are:
• AES – sync is derived from Channel 1 of the AES/EBU digital audio input.
• ADAT – sync is derived from ADAT input 1.
• S/PDIF – an S/PDIF digital audio signal connected at the rear panel may be used as the
sync source.
• WORD CLOCK – a dedicated word clock input is provided on the rear panel to permit
RedNet 3 – and the entire RedNet network – to be locked to a studio master word clock
source.
• INTERNAL – synchronisation is derived from the RedNet 3's internal clock. If any of the
external sync sources are selected, but no valid signal is available, the unit's clock source
will switch automatically to internal sync. The selected clock (internal or external) is
available at a Word Clock Output connector for connection to other digital audio devices
outside the RedNet network.

7. AES/EBU INPUTS/OUTPUTS – 25-pin female Dsub connector, conforming to AES 59, for
connecting up to 8 digital audio sources (4 AES/EBU pairs) to the RedNet system, and also
for outputting up to 8 digital audio channels (4 AES/EBU pairs). See page 12 for connector
details.
8. OPTICAL INPUTS 1-8 – these are for connection to a multichannel audio source with ADAT-
format optical outputs. The connectors are TOSLINK type. Note that each connector carries
eight separate audio channels at 44.1/48 kHz sample rate, four at 88.2/96 kHz, or two at 192
kHz.
9. OPTICAL OUTPUTS 1-8 – optical TOSLINK type connectors each carrying ADAT-format digital
audio bitstreams, with eight, four or two audio channels per connector depending on sample
rate, as above.
10. S/PDIF OUTPUT – phono (RCA) socket carrying two channels of digital audio in S/PDIF
(professional) format.
