STEP-BY-STEP GUIDE
This section guides you through setting up the unit for basic operation.
Preliminaries
The Menu / Setup Guide sheet details the menu structure, and two basic set-ups excluding the
Upsampler.
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 SDIF, Word Clock or SPDIF BNC interfaces, use 75Ωcoax cables fitted with BNC plugs.
•for SPDIF RCA interfaces, use 75Ωcoax cables fitted with RCA Phono plugs.
•for TOSLINK optical interfaces, use Toslink fibre-optic cables.
•for IEEE 1394 interfaces, use the IEEE 1394 cable provided with the unit.
•for the USB interface, use a screened USB type B cable.
Connect the power cable supplied to the power inlet on the Upsampler 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.
Press the Power button and wait about 30 seconds while the Upsampler configures itself. The display
will show in sequence: dCS, Scarlatti Upsampler, then the settings screen.
If the unit is likely to be set in an unfamiliar state, you can reset it as follows:
Press the Menu button, press the →button once, then the Menu button again to display the
Upsampler Settings menu. Press the ←button a few times to highlight the Factory Reset menu page.
Press the Menu button and wait a few seconds while the unit resets itself. The display shows:
No Input>24/96

dCS Scarlatti Upsampler User Manual Software Issue 1.1x
August 2011
Filename: Scarlatti Upsampler Manual v1_1x.docx Page 7 English version
STEP 1 - Connecting an Input
Use suitable cables to connect your source equipment to the matching digital input connectors on the
back panel of the Scarlatti Upsampler. The digital inputs are labelled in green print. The unit will
accept up to 24-bit data at 32, 44.1, 48, 88.2 or 96kS/s. You can connect any interfaces you need or
all 6 if you wish.
Use the INPUT button on the front panel to select the input you require, the choices are:
AES RCA1 RCA2 BNC TosLink USB
The icon for the selected input will appear at the top left corner of the screen. If the source is
generating recognisable PCM, the Upsampler will lock, displaying Sync and the input / output sample
rates. For example, when connected to an AES source generating 16/44.1 data:
16/44.1>24/96
Sync
Go to STEP 2.

dCS Scarlatti Upsampler User Manual Software Issue 1.1x
August 2011
Filename: Scarlatti Upsampler Manual v1_1x.docx Page 8 English version
STEP 2 – Setting up the USB source
The USB interface can be connected to a WindowsTM Vista/7 or XP (SP3 or later) PC, MacTM OSX
(10.5.4 or later) systems or a sound server, running software to generate PCM data.
If you do not want to use a USB source, go to STEP 3.
A word about Music Playing Software
There are countless programs that can play music on WindowsTM PC and Apple MacTM OSX systems.
Unfortunately, not all of them present the data completely unprocessed to the USB ports. For
example, Windows Media Player re-samples all data to 24 bits, albeit at the original sample rate,
whilst iTunes rate converts data as necessary to the output sample rate set in the OSX Audio set-up
panel.
With such a proliferation of playing software, and with updates being issued daily, it is impossible for
dCS to be fully up-to-date with the behaviour and performance of all programs. If you have questions
or problems, we would urge you to take them up with your software vendor. What we will say is that
different programs operate very differently and it is well worth finding out exactly how your particular
program processes the audio.
One particular problem that has been identified and is worthy of note, concerns the popular iTunes
program when running on Windows systems. The default output word length is 16 bits and must be
changed to 24 bits for correct operation. To do this, click on Start > Control Panel > Quicktime.
Click on the Audio tab of the Quicktime panel and select 24 bit in the Size field of the Sound Out
section.
Selecting the Scarlatti Upsampler as your Audio Output device
Whichever program you are using to play your music, your computer may not automatically select
your Scarlatti Upsampler as the preferred playback device. You can correct this as follows :
Windows XP - Once you have connected the Scarlatti Upsampler and switched it on, go to Start >
Control Panel > Sounds and Audio devices. Click on the Audio tab and select dCS Scarlatti from
the drop down list in the Sound Playback Default device list.
Windows 7 / Vista - Once you have connected the Scarlatti Upsampler and switched it on, go to Start
> Control Panel > Hardware and Sound > Sound and click on the Playback tab of the panel that
appears. dCS Scarlatti will appear in the list of available devices. For best results, set the Sample
Rate to be the same as that of the file.
MacTM OSX - Once you have connected the Scarlatti Upsampler and switched it on, open Finder,
click on the Go tab and select Utilities. In the Utilities panel, select Audio MIDI Setup and click on
the Audio Devices in the Audio MIDI setup panel. Select dCS Scarlatti from the drop down list in the
System Output. You can also set dCS Scarlatti as the default output from the same panel. For best
results, set the Sample Rate to be the same as that of the file.
For more detailed advice, please visit www.dcsltd.co.uk/page/support and download the “dCS Guide
to Computer Audio”.
Go to STEP 3.

STEP 3 – Connecting an Output
Choose which output interface you want to use and connect it up as described below. You can
connect as many outputs as you wish.
!
If the output format is not compatible with a particular interface, that interface will not be
active (for example, the AES1 output cannot carry DSD).
The Upsampler will not output sample rates that are lower than the input sample rate.
Single wire PCM
Connect one or more of the PCM outputs (AES1, AES2, RCA1, RCA2) to matching inputs on your
DAC. Use the OUTPUT button on the front panel to set the output sample rate to 32, 44.1, 48, 88.2 or
96kS/s. Use the DAC’s INPUT button to select that input.

Connect the AES1 and AES2 outputs to matching inputs on your DAC. Use the OUTPUT button on
the front panel to set the output sample rate to 88.2, 96, 176.4 or 192kS/s. If you choose 88.2 or
96kS/s, open the menu, scroll to the Upsampler Settings page and make sure Dual AES is set. If it is
not, scroll to Single AES and press the MENU button to change it to Dual AES. Use the DAC’s INPUT
button to select the Dual AES input. You may need to open the DAC’s menu and set it to accept Dual
AES.
!
All dCS DACs are capable of Dual AES operation, but some other manufacturer’s DACs
may have 2 single AES inputs that are not Dual AES capable. Please check the DAC
manual to be sure.

1394 interface
Connect the Upsampler’s 1394 output to the 1394 interface on a dCS DAC. Use the OUTPUT button
on the front panel to set the output format to DSD. If the DAC and the Upsampler are not locked to a
master clock, also connect the Upsampler’s W/Clock Output to the DAC’s Word Clock Input. Use the
DAC’s INPUT button to select the 1394 input. If necessary, set the DAC to sync to its Word Clock
Input. The DAC will lock and display SUP.
!
The Upsampler’s 1394 interface is unlikely to work with other manufacturer’s 1394
interfaces due to proprietary encryption.
!
You can connect 1394 cables in a “tree”, but do not connect them in a loop as this
prevents the system initialising.

Filename: Scarlatti Upsampler Manual v1_1x.docx Page 12 English version
STEP 4 - Setting the Sync Source
The system has been set up to lock to the clock generated by the source, (unless you are using the
USB input) and the Sync icon should be displayed. To check this, press the Menu button, press the
→button once, then the Menu button again to display the Upsampler Settings menu. If the Upsampler
was reset at the start of this procedure, you should see the Sync Source – Audio icon:
This is the simplest arrangement, but it does not give the best sonic performance due to clock jitter.
You can improve the performance by adding a Master Clock to your system.
Using the USB input in Master Mode
Jitter from computer sources is typically very severe and can degrade the audio quality. To avoid this,
the Upsampler’s USB interface runs in Asynchonous mode. The Upsampler does not lock to the
source clock, but uses the Upsampler’s internal clock instead - this is called Master Mode - and
adjusts the source to the same clock frequency. To use the this mode:
•Connect the Upsampler’s USB interface to a suitable source.
•Use the Upsampler’s INPUT button to select the USB interface.
•Press the Menu button, press the →button once, press the Menu button to display the Upsampler
Settings menu, press the →button to select the Sync Source page and then press the Menu
button as necessary to change the setting to Master:
•Set the Upsampler’s OUTPUT rate as you wish, connect the appropriate outputs to the DAC and
use the DAC’s INPUT button to select that input.
The Upsampler will draw data from the source, but it is not locked to the source, so Sync is NOT
displayed. You can improve the performance by adding a Master Clock to your system.
Using a Master Clock
If you have a Scarlatti Clock (or other dedicated Clock) in your system, lock the source, the Upsampler
and the DAC to the Clock for the best performance. To do this:
•Connect the Clock’s Word Clock Outputs to the Word Clock Inputs on the source, Upsampler
and DAC.
•Set the Clock Frequency to suit the source and DAC. For a CD Transport as source with the
Upsampler set to output 24/176.4 or DSD, the correct frequency is 44.1kHz. For a 24/48 source
with the Upsampler set to 24/192, the correct frequency is 48kHz.
•Select the required input on the Upsampler and DAC. This is important because these units store a
different Sync Source setting for each input.
•To set the Upsampler to lock to the Clock, press the Menu button, press the →button once, press
the Menu button to display the Upsampler Settings menu, press the →button to select the Sync
Source page and then press the Menu button as necessary to change the setting to WClk:
•The Scarlatti Upsampler will display Sync, provided the clock is recognised. If there is no signal at
the Word Clock In connector or it is not recognisable, the Upsampler will sync to audio and display
this icon to warn you:
•The Scarlatti Transport will automatically lock to the Clock and display Sync.
•Set the Scarlatti DAC to sync to Word Clock by pressing the SYNC button as necessary.

Digital Inputs
All the digital inputs will accept up to 24-bit PCM data at 32, 44.1, 48, 88.2 or 96kS/s.
The standard PCM inputs are AES on a 3-way female XLR connector (J), SPDIF inputs RCA1 and
RCA2 on RCA phono connectors (K), an SPDIF input on a BNC connector (L) and an optical SPDIF
on a TosLink connector (M) .
The USB interface on a ‘B’ type connector (T) will accept music data streamed from a Windows™ PC,
MAC™ or sound server equipped with a USB 2.0 interface.
!
We have tested this interface with several common formats running on Windows™ 7,
Windows™ Vista, Windows™ XP and MAC™ OSX 10.5 / 10.6 but we cannot accept
responsibility for correct operation with all source devices, operating systems or
software.
Digital Outputs
All of the outputs consistent with the selected output mode are active at the same time.
All the single-wire PCM digital outputs generate 24-bit PCM data at 32, 44.1, 48, 88.2 or 96kS/s.
!
The Scarlatti Upsampler does not have facilities to reduce the word length of PCM data to
less than 24 bits. It will not give good results with older DACs or other equipment that
cannot process 24-bit data. ALL dCS equipment will accept 24-bit PCM data.
The AES1 and AES2 outputs (Q) can be used individually at up to 96kS/s or as a Dual AES pair at
88.2, 96, 176.4 or 192kS/s. These outputs are disabled in DSD mode.
!
For Dual AES operation at 88.2 or 96kS/s, the Dual AES menu page must be set to Dual
AES, otherwise both outputs will carry single AES data.
2 SPDIF outputs are provided, RCA1 and RCA2, on RCA phono connectors (R). These outputs carry
SPDIF data for output rates up to 96kS/s, even if Dual AES mode is set. They are disabled if the
output is set to 176.4kS/s, 192kS/s or DSD.

The SDIF interface outputs SDIF-2 PCM data for output rates up to 96kS/s, even in Dual AES mode is
set. The interface consists of two data inputs labelled CH1 and CH2 (P). The interface is disabled if
the output is set to 176.4 or 192kS/s or DSD. We recommend connecting the W/Clock Output as part
of the SDIF interface, this is required with dCS equipment.
The IEEE 1394 interface (S) outputs encrypted DSD data. 1394 interfaces are great for carrying lots of
digital data - but are very poor at transmitting a stable clock, so a separate Word Clock connection is
required. The two 1394 ports are identical – they can be used as data outputs or as a pass-through.
Note that the 1394 bus must not be connected in a loop as this will prevent the system initialising.
Word Clock Input / Output
The W/Clock In connector (N) will accept standard word clock from the source equipment or a master
clock at 32, 44.1, 48, 88.2 or 96kHz. Unlike the DAC, the clock frequency does not need to be an
exact multiple of the input data rate provided the two rates are synchronous. Set the Upsampler
Settings / Sync Source menu page to WClk when locking to an external word clock. Note that the
source (e.g. the CD Transport) MUST be locked to the same clock, otherwise the SYSTEM will not be
locked and periodic clicks will be heard on the outputs.
The W/Clock Out connector (O) carries word clock at the same frequency as the single-wire output
sample rate, or 44.1kHz for DSD. For example, if the output is set to 192kS/s Dual AES, the W/Clock
Out connector carries a clock at half this rate – 96kHz.
Word clock is used for synchronisation only, it does not carry digital data.
SUC Connector
The SUC connector (U) is an RS232 interface, primarily used to remotely control the unit during
automated testing. Please contact dCS for advice on using this interface with a household automation
system. Note that we recommend using infra-red remote control instead.
Mains inlet
Power is connected via a standard IEC320 connector (V), protected by a fuse (W) and isolated by a 2-
pole power switch (X).
