Focusrite RedNet PCIe R Card [17/66] Rednet 3

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 network clock (whether derived from

an external clock, RedNet 3’s internal clock or another Dante device on the network) is

available at the Word Clock Output connector for connection to other digital audio devices

outside the 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 20 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.
