topology.
Digital inputs
4x AES/EBU on 3-pin female XLR connectors.
Each will accept up to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4 or 192kS/s
or DSD/64 in DoP format,
OR
used as Dual AES pairs at 88.2, 96, 176.4, 192, 352.8 or 384kS/s or
encrypted DSD or DSD/64 or DSD/128 in DoP format.
3x SPDIF on 2x RCA Phono and 1x BNC connectors. Each will accept up to
24 bit PCM at 32, 44.1, 48.88.2, 96, 176.4 or 192kS/s or DSD/64 in DoP
format.
1x SPDIF optical on a Toslink connector, will accept up to 24 bit PCM at 32,
44.1, 48, 88.2 or 96kS/s.
1x SDIF-2 interface on 2x BNC connectors, will accept up to 24 bit PCM at
32, 44.1, 48, 88.2 or 96kS/s or SDIF-2 DSD (auto-selected). This interface
requires a compatible word clock connected to one of the Word Clock
Inputs, locked to the data rate.
USB interface on a B-type connector, will accept up to 24 bit PCM at:
• 44.1, 48, 88.2 or 96kS/s when set to USB Class 1 (no driver required).
• 44.1, 48, 88.2, 96, 176.4, 192, 352.8 or 384kS/s when set to USB Class 2
(no special driver is required for OSX 10.6 onwards, load the latest dCS
USB Class 2 driver for Windows).
• Set to USB Class 2, decodes DSD/64 or DSD/128 in DoP format.
The USB interface operates in true asynchronous USB mode.
Clocking
3x Word Clock Inputs on 3x BNC connector, accept standard word clock at
32, 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as
the clock rate or an exact multiple (0.25x, 0.5x, 1x, 2x, 4x, 8x) of the clock
rate. Sensitive to TTL levels.
Word Clock Output on 1x BNC connector. In Master mode, a TTL-compatible
word clock appears on this output, not temperature compensated. The word
clock frequency is either 44.1 or 48kHz, depending on the incoming data
rate. In Universal Master Mode, a TTL-compatible 38.4kHz word clock
appears on this output, for connection to the Vivaldi Upsampler.
