Which types of disc can be played?
Commercially manufactured CDs can be played if they:
•are 12cm or 8cm round discs
•are recorded with linear PCM digital audio data
•carry the Compact Disc Digital Audio logo and meet the “Red-Book” standard.
Commercially manufactured single-layer SACDs or hybrid SACD/CD discs can be
played if they:
•are 12cm or 8cm round discs
•are recorded with DSD digital audio data on the SACD layer
•carry the Super Audio CD logo and meet the “Scarlet-Book” standard.
CD-R
CD-RW
CD-R or CD-RW discs recorded with audio data in CD format may be playable, but
this depends on the disc, the software and the burner used to record on the disc.
Similarly, DVD-R discs burned with an SACD image may be playable. dCS cannot
accept responsibility for any difficulty encountered while attempting to play such
discs.
Which types of disc can NOT be played?
dCS cannot accept responsibility for any difficulty encountered while attempting to play the following
types of disc:
•Scratched, damaged or dirty discs.
•Non-circular “discs”, such as square or heart-shaped.
•Printed or labelled CD-Rs or discs contaminated with glue or other sticky substances.
!
Contaminated discs may get stuck to the turntable inside the unit. If this happens, a
service charge will be made for removing the disc and repairing any damage.
•DVD, CD-G, CD-EXTRA, PHOTO CD, CD-ROM or DVD-ROM.
•Discs recorded with digital audio data that is not in CD-format or SACD-format (e.g. FLAC or WAV
files).
•Copy-protected discs that do not conform to the “Red-Book” CD standard may not play correctly or
may not play at all. Such discs are not CDs – they are optical discs that have been recorded with
digital audio data. They should not carry the Compact Disc Digital Audio logo – but some do. If you
encounter any difficulty playing such discs, please contact the disc manufacturer and demand a
genuine CD in exchange.

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.
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 Word Clock or SPDIF BNC interfaces, use 75Ωcoax cables fitted with BNC plugs.
!
Word Clock 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.
Connect the power cable supplied to the power inlet on the Transport 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 – the unit will
display Rossini Transport. Wait about 30 seconds while the Transport 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.

STEP 1 – Connecting a Digital Output
While playing an SACD, the AES1+2 interface carries DSD data. While playing a CD, the AES1+2
rate is set by the Upsampling menu page – we will assume it is set to DSD. The AES3, SPDIF1 and
SPDIF2 outputs carry 16/44.1 PCM data with either disc type. Most owners connect the AES1+2
interface only, but some prefer to listen to CDs in the native 16 bit 44.1kS/s format.
Connecting the Dual AES interface
When used with a Rossini DAC, AES1+2 is the main output.
•Connect the AES1 output on the Transport to the AES1 input on the Rossini DAC rear panel and
the AES2 output to the AES2 input, using two XLR cables. Ensure the cables are not swapped.
•Press the DAC’s Input button repeatedly until AES1+2 is displayed.
The DAC will lock to the source, displaying the Audio Sync icon and DSD.
Figure 1 – Basic setup
Connecting the AES3 or an SPDIF output
•Connect one of the single-wire outputs on the Transport to the matching input on the DAC using a
suitable cable.
•Press the DAC Input button repeatedly until your chosen input is displayed.
The DAC will lock to the source, displaying the Audio Sync icon and 0/44.1.
Why does the DAC display 0/44.1? Is the Transport faulty?
No, the Transport is working correctly. When a CD is loaded but is not playing, a
44.1kS/s carrier signal is being transmitted but there is no data – just digital silence. The
DAC correctly reports zero active data bits until the disc starts playing, then it detects 16
active bits and updates the display. 0/44.1 may be displayed briefly between tracks also.
Proceed to Step 2.

Rossini Transport Manual v1_0x Page 12 English version
STEP 2 – Choosing a Sync Mode
So far, the system has been set up to lock to the clock generated by the source. This is the simplest
arrangement, but it does not give the best sonic performance due to clock jitter.
Using the DAC in Master Mode
If you have a Rossini Clock, go to the next page.
You can reduce the jitter in your system by using the Rossini DAC in Master mode and slaving the
Transport to it.
Figure 2 – Using the Rossini Transport with the Rossini DAC in Master Mode
•Use the DAC’s Input button to select the input you want to use (AES1+2 in the example).
•Connect the DAC’s Word Clock Out connector to the Transport’s Word Clock In connector.
Set the DAC’sSettings > Sync Mode menu page to Master mode.
The Transport will lock to the Word Clock and display this icon.

Using a Master Clock
The performance can be improved further by adding a Rossini Master Clock to the system.
Figure 3 – Using the Rossini Transport, DAC and Clock together
•Use the DAC’s Input button to select the input you want to use (AES1+2 in the example).
•Connect the Clock’s Output 1 to the DAC’s Word Clock In1.
•Connect the Clock’s Output 3 to the Transport’s Word Clock Input.
The Transport will lock to the Word Clock and display this icon.
Set the DAC’s Settings > Sync Mode menu page to Word Clock In1 and allow the
system to re-lock.
The “Bad clock” icon indicates that the Transport is receiving word clock at a frequency
other than 44.1, 88.2 or 176.4kHz and it cannot lock to it.
•If you intend to use other sources with the DAC, connect the Clock’s Output 2 to the DAC’s Word
Clock In2.
•Make sure that the Clock is mechanically isolated from the other units, especially from the
Transport.
Proceed to Step 3.

the Stop/Eject button again.
The display will show CLOSE, then LOADING. The disc type will be identified, either CD or the SACD
logo will appear on the display, along with the number of tracks and the total playing time. The
Transport will play the SACD layer of a hybrid disc by default, but if you wish, you can select the CD
layer instead by pressing the Layer button.
•Press the Play button. Turn up the Volume to a comfortable level.
You should have audio. For all discs, the disc type and elapsed time will be displayed.
•Press the Play/Pause button to pause playing, press again to resume playing.
•Press the Fwd or Rwd button to skip to the next track or the previous track.
•Hold down the Fwd or Rwd button to jog through the track - the speed will increase the longer you
hold the button down. Most owners will use the remote control for this.
•Press the Stop/Eject button to stop the disc. Press it again to open the tray.
The IR Remote Control gives access to other features, such as track number selection, repeat track or
disc and programming a track sequence.
To program the track sequence 6 - 8, stop the disc and press the remote Program button – the
Transport will display P00. As an example, press 6or 06 – the display will change to P01. Press 8or
08 – the display will change to P02. Start the disc to play the track sequence. Press the remote
Program button to toggle in/out of program mode. Press the Clear button to cancel program mode. or
open the CD tray.
The next step is crucial – sit back and enjoy the music.
When you have finished listening, you can either keep the system warm by setting it to Sleep mode
(press the Power button briefly) or switch off (hold down the Power button until SWITCHING OFF is
displayed, then release).
Controlling Disc playback with the app
!
App control is not implemented in the initial release for the Rossini Transport (v1.00), the
current versions of the Rossini Player / DAC (v1.10) or the Rossini app (v1.4.8). We
intend to add this feature in the next set of updates. Please see www.dcsltd.co.uk for
news.
You can use the Rossini app to control the Transport via a Rossini DAC or Player.
•Connect the DAC / Player to the Transport with Dual AES.
•Connect the DAC / Player to the Transport with an RS232 “null modem” cable between the RS232
ports.
Set the RS232 Mode on the Transport and DAC / Player to Binary.
Go to the app’s Home page and tap Disc.
The Rossini app will then give access to the same features as on the IR remote control.

dCS Rossini Transport User Manual Software Issue 1.0x
September 2018
Rossini Transport Manual v1_0x Page 15 English version
When set up in this way, the Transport’s IR receiver is active only if the Rossini DAC /
Player’s Dual AES input is selected. This prevents control conflicts.
The app’s CD page is replaced by the Disc page when the Transport is connected to Player / DAC.
Playback information will be displayed on the Player / DAC’s front panel.
Further suggestions
•If you wish, you can set the Transport’s AES1+2 output to generate DXD data (24/352.8) or DSDx2
(1/5.644M) when playing a CD instead of DSD, by changing the Settings > Upsampling Mode
menu page (see page X24X).
•If you are using the AES1+2 output only, try setting the PCM Enable menu page to Off (see page
X24X).
•If you are using a Rossini Master Clock, try turning the Dither feature on. Please refer to the
Rossini Master Clock manual for more information.
