STEP-BY-STEP GUIDE
This section guides you through setting up the unit for basic operation.
Preliminaries
The Menu Guide sheet details the menu structure and describes the two most common set-ups.
For digital interfaces, use with cables designed for digital audio:
•for AES/EBU interfaces use 110Ωscreened, twisted pair cables fitted with one male XLR connector
and one female XLR connector.
•for Wordclock or SPDIF BNC interfaces, use 75Ωcoax cables fitted with BNC plugs.
Wordclock interfaces require a simple DC-coupled connection. The interfaces may
malfunction or not work at all if capacitor coupled cables or cables with built-in networks
are used.
•for SPDIF RCA interfaces, use 75Ωcoax cables fitted with RCA Phono plugs.
•for TOSLINK optical interfaces, use Toslink fibre-optic cables.
•for the Network interface, use an RJ45 Ethernet cable, such as that provided with the unit.
•for the USB1 interface, use a standard screened USB 2.0 cable fitted with one type ‘A’ connector
and one type ‘B’ connector. The internal screen must be connected at both ends.
For analogue outputs, use with screened cables of the correct type:
•for balanced outputs, use screened, twisted pair cables fitted with one male XLR connector and one
female XLR connector.
•for unbalanced outputs, use coax cables fitted with RCA Phono plugs.
Some “audiophile” cables have unusual grounding or screening arrangements, or do not
have the correct characteristic impedance. If you have difficulty using such cables but
the problems disappear when ordinary cables are substituted, please ask the cable
manufacturer or your dealer for support.
Connect the power cable supplied to the power inlet on the Player’s rear panel, plug the other end into
a convenient power outlet.
!
Please do not use an excessively heavy or inflexible power cable as this may damage
the power inlet connector.
The cables supplied with the unit are “commercial grade”, because most owners will have
their own “audiophile grade” cables or will prefer to make their own cable choices.
Set the rocker switch near the mains inlet to the Iposition, press the Power button.
Wait about 30 seconds while the player configures itself. If the unit is likely to be set in an unfamiliar
state, you can run the Factory Reset routine by pressing the buttons in this sequence: Menu, ►, ►,
►, Menu, ◄, ◄, Menu. Wait a few seconds while the unit resets itself.
dCS Vivaldi One Digital Playback System User Manual Software Issue 1.0x
September 2017
Vivaldi One Manual v1_0x Page 11 English version
STEP 1 – Connecting the analogue outputs
Choose one of the following two sections:
Using a preamplifier
•Set the preamplifier volume control to a low level.
•Connect either the balanced (XLR connectors) or unbalanced (RCA phono connectors) outputs on
the player’s rear panel to matching line level inputs on your preamplifier (probably labelled CD or
AUX).
•Turn the player’s rotary control clockwise to set the Volume to maximum (- 0.0dB on the display).
•Slowly increase the preamplifier volume until the music is at the right level.
•If the preamplifier volume setting for a comfortable listening level is too high or too low, you may
need to change the Output Level setting.
•Press the buttons in this sequence: Menu, ►, ►, Menu, ►, Menu.
Setting the Output Level to 6V can cause some preamplifiers to distort. For this reason,
we recommend the 2V setting if a preamplifier is used.
Using a power amplifier directly
•Set the player’s Volume to around -40.0dB as shown on the display.
•Connect either the balanced (XLR connectors) or unbalanced (RCA phono connectors) outputs on
the player’s rear panel to matching inputs on your power amplifier. Switch on the power amplifier.
•Turn the player’s rotary control slowly clockwise until the music is at the right level.
•If the Volume setting for a comfortable listening level is higher than –10.0 or lower than –30.0, try
changing the Output Level setting.
•Press the buttons in this sequence: Menu, ►, ►, Menu, ►, Menu.
Balanced Outputs
!
The most common fault reported when using our balanced outputs is hiss, unstable levels
and a thin sound on both channels. This is caused by connecting the player’s balanced
output stage to an unbalanced input on an XLR connector with pin 3 left unconnected.
This does not work correctly with a balanced and floating output stage – you must connect
pin 3 to pin 1 (ground) to complete the signal path.
Another possible cause of this fault (probably on one channel only) is a broken cable.
Figure 1 – Output connections for the Vivaldi One
The Vivaldi One has independent balanced and unbalanced output stages, you can connect them to
different amplifiers if you wish.

Vivaldi One Manual v1_0x Page 12 English version
STEP 2 – UPnP Network Connection
UPnP (Universal Plug and Play) is a set of protocols designed to allow consumer devices to interact
over a network. The Vivaldi One complies with the UPnP AV protocol, enabling it to communicate with
other non-dCS devices, provided they also comply with this protocol.
A network streaming system is made up of three standard UPnP components: UPnP Control Point,
UPnP Media Renderer and UPnP Media Server. A system may consist of one or more of each of these
components. In such a system, all of the media (songs, tracks, videos, etc) is stored on the server. This
storage device can be a NAS or a Computer. The control point (e.g. a tablet or smart phone) requests
the address of a particular item of media from the server (e.g. a NAS drive). It then passes this address
to the renderer (e.g. a Vivaldi One) to play. The renderer directly retrieves the item from the specified
address on the server, decodes and plays the media as it arrives over the network from the server.
Enabling network streaming of audio using a Vivaldi One relies on the presence of standard network
infrastructure in your system. A description of the network will not be discussed in this manual but at a
minimum the following components are required for system setup: Router, Computer, Vivaldi One, NAS,
Wireless access point (WAP), Wireless control point.
Please note that Ethernet cables are required to connect the devices and the NAS must have UPnP
media server software (e.g. Twonky, Asset, MinimServer) installed. If the UPnP control point is having
problems seeing the UPnP media server or the UPnP media renderer, you might need to disable IGMP
snooping in the router or enable UPnP discovery mode in the router or the NAS drive.
The dCS Vivaldi 2.0 App is a control point application that will allow users to view / select available
renderers, view / select available media servers and browse / select / playback music via the Vivaldi
One. The dCS Vivaldi 2.0 app is currently available for iOS.
Compatibility
The Vivaldi One and the app are compatible with:
•iPad 2 or later.
•iPhone 5 or later.
•iPod Touch 5th generation.
Vivaldi 2.0 App version 1.4.4 has been tested with iOS 10.
Basic set-up
•Connect the system as shown below.
Figure 2 – Connecting Vivaldi One to a network
•For iPad or iPhone/iPod, download the dCS Vivaldi 2.0 App from the App Store and install it.
•Connect the player’s Network Main interface to the Ethernet network.
•Connect the control device (e.g. iPad) to the network.
•Launch the dCS Vivaldi 2.0 App.

Vivaldi One Manual v1_0x Page 19 English version
STEP 3 – Using the player’s PCM Inputs
The player has 6 standard PCM inputs, which may be used with a wide variety of sources.
When playing data over AES or SPDIF from a device that does not have a wordclock input,
always set that input to Audio sync – do not try to lock it to a Master Clock.
Switch on the source equipment. If appropriate, load a disk / tape / file and set the machine in PLAY
mode to ensure it is generating a digital audio data stream.
Choose one or both of the following two sections:
Connecting to a Dual AES Source
•Check that your source equipment is capable of Dual AES operation and is set up correctly. This will
probably be a dCS SACD Transport, a dCS Upsampler or a sound server.
Press Menu, ►, ►, ►, Menu, ►to select the Unit Settings > Dual AES menu page and
use the Menu button to ensure it is set to Auto.
•Connect the AES1 (or AES A) output on your source equipment to the AES1 input on the player’s
rear panel and the AES2 (or AES B) output to the AES2 input, using two XLR cables. Ensure the
cables are not swapped.
•Use the Input button to select the AES1 input.
If this icon is not displayed, open the Menu and select Unit Settings > Sync Mode > Audio
Sync.
The player will lock to the source and automatically select AES1+2, displaying 24/352.8 for example, if
the source is generating that format.
Connecting to a Single AES or SPDIF source
Most digital audio source equipment (such as CD transports, DVD players) is fitted with a single wire
digital output, usually on an RCA phono connector. Satellite receivers often have a Toslink optical
output.
•Connect your source equipment to the matching input on the player’s rear panel using a suitable
cable.
•Press the Input button repeatedly until your chosen input is displayed. This will be either AES1,
AES2, SPDIF1 (RCA), SPDIF2 (RCA), SPDIF3 (BNC) or SPDIF4 (Toslink).
If this icon is not displayed, open the Menu and select Unit Settings > Sync Mode > Audio
Sync.
The player will lock to the source, displaying 16/44.1 for example, if the source is a CD player.

Figure 3 – Connecting Vivaldi One to a Blu-ray Player
If the inputs have been renamed, the standard names will not be displayed.
Why does the player display 0 bits? Is it faulty?
No, the player is working correctly. When the source equipment is connected but is not
playing, there is no data – just digital silence. The player correctly reports zero active data
bits until the source starts playing, then it detects the number of active bits and updates
the display. 0 bits may be displayed briefly between tracks also.
You can select the digital inputs from the app by going to the Home page and selecting
Digital.
