USING THE dCS Scarlatti Upsampler FOR THE FIRST TIME
Congratulations on purchasing your dCS Scarlatti Upsampler.
Before using your unit, please read this section and the Step by Step Guide. This will enable you to
set the unit up quickly and safely with your hi-fi system.
From time to time, dCS will release updated software on CD that you can install yourself using the CD
Update feature. Please check our web-site occasionally to see if new Scarlatti software is available, or
consult your dealer.
What’s in the box?
Check that the box contains the following items:
• dCS Scarlatti Upsampler
• Manual and Menu / Setup Guide
• Power cable
• IEEE1394 cable
• USB cable
• BNC cable
• Spare fuses
Notify your dealer as soon as possible if anything is missing or damaged. We suggest that you retain
the original packaging for possible future use. If this is not possible, replacement packaging can be
ordered from dCS or our distributors. Details can be found on our web site at www.dcsltd.co.uk
The Scarlatti Transport

.
Positioning the unit
Units in the Scarlatti range are designed to be mounted on separate shelves of a rack and must NOT
be stacked directly on top of each other. Place each unit on a firm, vibration free base, allowing
convenient connection to the other parts of your system. To prevent overheating, we recommend that
you leave some free space around the unit to allow for ventilation.

Safety Notice
Your dCS Scarlatti Upsampler contains no user serviceable parts. DO NOT attempt to
open the case as there are potentially dangerous voltages present inside. In the event of
the unit developing a fault, please contact your dealer in the first instance.
To maintain protection from electric shock, the unit MUST be connected to mains earth
(ground) via the power cable. Also, unearthed systems do not give the best sonic
performance.
This product is lead-free and complies with the RoHS directive.
Before connecting the power cable to the unit for the first time, please check that it has been set to the
correct operating voltage for your mains supply. The unit’s voltage setting is shown on the serial
number label. If this does not match your local supply voltage, DO NOT attempt to use the unit.
Contact your dealer to have the unit reset. Using the unit with the wrong mains setting for your local
supply may result in serious damage to the unit and will invalidate the warranty. Do not attempt to
reset the voltage yourself.
We do not recommend the use of mains regenerators. However, if you do wish to use a mains
regenerator with variable voltage and frequency, we recommend that you set the voltage to match
your local voltage and the frequency to either 50Hz or 60Hz ONLY.
Damage caused to your Scarlatti Upsampler by misuse of a mains regenerator or by a
!
malfunctioning mains regenerator is not covered by the warranty.
Disposal at end-of-life - the symbol indicates that this product should not be treated as
normal household waste. It should be recycled, so please take it to an approved
collection facility.
Patent Pending
This product contains novel features that are the subject of patent application GB0817141.5.

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 110Ω screened, twisted pair cables fitted with one male XLR
connector and one female XLR connector.
• for SDIF, Word Clock or SPDIF BNC interfaces, use 75Ω coax cables fitted with BNC plugs.
• for SPDIF RCA interfaces, use 75Ω coax 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
!
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:
the power inlet connector.

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.

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 Windows
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.
TM
PC and Apple MacTM OSX systems.
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.
TM
OSX - Once you have connected the Scarlatti Upsampler and switched it on, open Finder,
Mac
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.

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
!
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.

The Upsampler will not output sample rates that are lower than the input sample rate.
