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 mode - 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 / 192kS/s under the control of a dCS Vivaldi HD App running on a suitable
iPad, iPhone, iPod Touch, (see page 18) or other UPnP control point.
dCS Apps for Android, Windows PC and Mac OSX PC are currently in development.
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.

USB Interfaces

Both USB interfaces operate in True Asynchronous USB mode, which makes the Vivaldi Upsampler
immune to clock jitter from the computer / sound server. The Upsampler uses its own internal clock or
locks to the Master Clock connected to one of the
cable to the computer controls the data delivery rate.
USB1
The interface on a 'B' type connector (V) will accept PCM data at up to 24 bits / 192kS/s from a
Windows™ PC, Apple Mac™ PC or sound server equipped with a suitable USB2.0 interface. The
interface will also accept DSD data packaged in DoP format.
We have tested this interface with several common formats running on Windows™ 7,
!
Windows™ Vista (SP2), Windows™ XP (SP3) and Apple Mac™ OSX 10.5 & 10.6 with
various PCM streaming programs but we cannot accept responsibility for correct
operation with all source devices, operating systems or software.

onwards, the dCS USB Class 2 driver is required for Windows).
USB2
The interface (W) on an 'A' type connector can stream PCM music files in most popular formats
at up to 24 bits / 192kS/s from a USB Flash Drive. With a Flash Drive connected, a basic browser (see
page 17) navigates to the music files and selects the file to be played. After closing the browser, the
name of the file is displayed, with a Play or Pause icon and the elapsed playing time.
Mains-powered USB hard disk drives in FAT16 or FAT32 format may be used in the same way. The
interface will not read drives in NTFS format or other formats.
USB2
The interface will also accept PCM music files up to 24 bits at 44.1 or 48kS/s streamed from an
iPod or iPhone. Note that metadata is not displayed.
