connect a 44.1, 88.2 or 176.4kHz word clock to
Word Clock
In2. With a source connected to another feed from the same Clock, the Upsampler can
select the correct clock frequency.
When the USB or Network interfaces are in use, the Upsampler can be locked to a 38.4kHz clock
generated by a Vivaldi DAC (v1.10 or later) set to
Word Clock Out
The
connector (S) carries word clock as follows:
• Single wire output – Word Clock Output frequency is the same as the sample rate.
• Dual AES output 88.2 to 192kS/s - Word Clock Output frequency is 0.5 x the sample rate.
• Dual AES output 352.8 or 384kS/s - Word Clock Output frequency is 0.25 x the sample rate.
• DSD output modes - Word Clock Output frequency is 44.1kHz.
Word Clock is used for synchronisation only, it does not carry digital data.
Network Interface
Network
The
connection on an RJ45 socket (U) acts as a UPnP
from a NAS drive or a local computer over a standard Ethernet network. The Upsampler can stream
music files at up to 24 bits / 384kS/s or DSD/128 under the control of a dCS Vivaldi App running on a
suitable iPad, iPhone, iPod Touch, (see page 18) or other UPnP control point.
The RJ45 socket's contacts can be damaged by accidentally inserting the wrong
!
connector (e.g. a USB type B or type A). To avoid this, we suggest leaving the dust
cover fitted when not in use and fitting the RJ45 cable immediately after removal.
