PRODUCT OVERVIEW

The dCS Verdi La Scala Upsampling SACD Transport is a logical development of the critically acclaimed dCS Verdi. La Scala plays SACD or Hybrid discs and outputs the DSD data onto an IEEE 1394 bus, ready for conversion to wide-band, high quality audio by a dCS Elgar Plus or a 1394-equipped dCS Delius2. La Scala also plays standard CDs and the CD layer of Hybrid discs, upsampling the data to DSD internally, without the need for a separate upsampler. This is ideal for audiophiles who do not use other digital audio sources, as the equipment set-up is much simpler. DSD (Direct Stream Digital) is single bit data, sampled at 2.822MS/s. This data format increases the available audio band-width to well over 100kHz, well in excess of the 20kHz available from a standard CD system. The extra bandwidth sharpens the transient response and improves the phase response, resulting in a more natural sound and more precise stereo imaging. CD data at 16 bits / 44.1kS/s is always available from the AES interface (XLR connector), three SPDIF interfaces (RCA, BNC and Toslink optical and an SDIF-2 interface. When playing and SACD, the data is down-sampled to provide these outputs. La Scala features a Wordclock Input, allowing the transport to be synchronised to a Master Clock or a dCS DAC running in master mode. This arrangement reduces system jitter a major source of sound degradation in digital audio systems. In common with all dCS converters, La Scala is based on our flexible digital audio platform which makes extensive use of software configurable chips FPGAs and DSPs. This allows the internal software to be updated from time to time, either from a dCS CD or from a PC, adding extra features and facilities to your system with a minimum of fuss.

GIUSEPPE VERDI (1813 1901)
The dCS Verdi is named after Giuseppe Verdi, the 19 century Italian composer. th He was born in the village of Roncole in the province of Parma on October 10 , 1813. From an early age he showed a strong interest in music and commenced his formal musical studies at the age of 7, tutored by the organist in his village church. When he was 10, Verdi moved to the nearby town of Busseto, where he attended the music school run by Ferdinando Provesi. In Busseto he made the acquaintance of Antonio Barezzi, a local merchant and passionate music lover. Barezzi provided Verdi with financial assistance during the remainder of his musical studies and many years later in 1836, Verdi married Barezzis daughter, Margherita. In 1832 he applied to study at the prestigious Milan Conservatory, but was turned down. Instead, he studied in Milan under the private tuition of Vincenzo Lavingna, a composer and former harpsichordist at the La Scala theatre. During his stay in Milan, Verdi spent a great deal of time attending the theatre and this almost certainly accounts for his work being heavily biased towards opera. On Provesis death in 1833, Verdi returned to Busseto with the aim of taking over his position as head of the towns music school. However, this was delayed until 1836 by political squabbling between the clergy and his supporters in the local Philharmonia. In 1838, Verdi moved to Milan where the following year he presented his first opera, Oberto, conte di San Bonifacio at the La Scala theatre, where it was received to moderate acclaim. 1840 must have been the worst year of his life. First his two children and then his wife died in quick succession. His misery was further compounded when his second opera, Un Giorno di Regno, closed after only one performance. At this point Verdi seriously considered giving up composing altogether. At the insistence of Bartolomeo Merelli, the impresario of the La Scala theatre, Verdi read a libretto written by Solera. The biblical themes deeply moved him and motivated him to write his second opera, Nabucco, which was hailed as a triumph when it was performed for the first time at La Scala in 1842. Nabucco firmly established Verdi as one of the leading Italian composers of the day. Verdi then commenced a period of prodigious creativity. Between 1843 and 1858 he wrote a total of 20 operas. Of these, 3 are especially of note and are still regularly performed: Rigoletto - written in 1851, Il trovatore and La traviata - both written in 1853. In 1859 he married his second wife, the soprano Giuseppina Strepponi, whom he had known since 1842 when she sang the female lead in Nabucco at La Scala. Verdis works often contained strong political themes. This interest in politics was carried over to his private life and, in 1861, he was elected as a deputy to the first Italian parliament. His success had made him a wealthy as well as famous man. He used his considerable fortune to progressively increase the size of his farm holdings in Parma. By 1900, these had become the largest revenue producer in the province.

He continued to compose, albeit at a slower pace. In 1873 he wrote his Requiem Mass, which was dedicated to the memory of the poet Alessandro Manzoni, though its origins go back to a work he first composed as a homage to Rossini. The most notable operas of his latter years are: Aida written in 1871, Otello - written in 1887 and Falstaff - written in 1893. The last two were based on plays by Shakespeare and are widely regarded as masterpieces. His last major work, the Four Sacred Pieces (Ave Maria, Stabat Mater, Te Deum and Laudi alla Vergine), was written in 1898, a year after the death of his second wife Giuseppina. Giuseppe Verdi died on January 27 1901. In accordance with his wishes, he was given a simple funeral, without singing or music. The following month, he was entombed in a state ceremony with his second wife, at the rest home for musicians that he had helped to set up many years before, to care for singers and instrumentalists who had fallen on hard times in their old age. The procession was accompanied by members of Verdis family, members of the Italian Royal family, members of Parliament, foreign diplomats and leading composers including Puccini, Mascagni and Leoncavello. Arturo Toscanini lead tens of thousands of mourners with the choruses of La Scala, in the singing of Va, pensiero from Nabucco.

Preliminaries Step 1 Connecting the System

While playing an SACD, Hybid disc or CD, DSD data is available from either of the 1394 connectors. This can be decoded by a 1394equipped dCS Elgar Plus or Delius DAC. do this: do this: do this: Set the DAC to 1394 mode first. Connect ONE of the 1394 connectors on La Scalas rear panel to the DAC using the IEEE 1394 cable supplied. Also connect La Scalas Wordclock Out to Wordclock In on the DAC. Do not connect both of La Scalas 1394 connectors to the DAC this prevents the IEEE 1394 interfaces synchronising.

Page 11

Connecting the DAC Outputs x do this: Connect the DAC analogue outputs to matching inputs on your preamplifier / power amplifier. Connect the power amplifier outputs to your loudspeakers. do this: Set the preamplifier or DAC Volume control to a low level. do this: Ensure all system components are switched on. This set-up is shown in Figure 1.

Connecting a PCM Output

For the best sound quality, use the 1394 interface. Standard CD data is available from all of the PCM outputs, if you want to use them. do this: Connect any of the AES, RCA, BNC or Toslink outputs on the La Scala rear panel to the matching inputs on the DAC using suitable cables. If you want to use SDIF-2 instead, connect the CH1 and CH2 outputs on the La Scala rear panel to the matching inputs on the DAC using suitable cables. Also connect the Wordclock Out output on the La Scala rear panel to the Wordclock In connector on the DAC.

Step 2 Playing a Disc
do this: Press the Stop/Eject button. The display will show Opening then Open. do this: Load a disc into the tray and either push the tray in gently or press the Eject button again. The display will show Loading, then Read TOC (reading the table of contents from the disc). The disc will be identified as a CD, SACD or hybrid. Either the CD or the SACD indicator will light, along with the CONT indicator (play all tracks in a continuous sequence). If the disc is a hybrid, the HYBD indicator and either the SACD or the CD indicator will light. You can select the other layer by pressing the SACD/CD button on the Remote Control the indicator will change to match this. If the disc has disc text, the TEXT indicator will light, the disc title and artists name will scroll across the display. For all discs, the number of tracks / total playing time will be displayed, followed by 0 (stopped). do this: do this: do this: Select the 1394 input on the DAC. Allow the DAC to lock and un-mute. Press the Play button. Turn up the Volume to a comfortable level. You should have audio. If the disc has disc text, the track name will scroll across the display. For all discs, the track number and elapsed time will be displayed. do this: do this: do this: do this: Press the Play/Pause button to pause playing, press again to resume playing. Press the Next Track or Previous Track buttons to skip to another track. Hold down the Next Track or Previous Track buttons to fast forward or fast reverse through the track.

Using the Menu

The Menu gives the user access to a wide range of additional features. It also allows new features and performance enhancements to be added at a later date by software upgrades. Opening the Menu The Menu is controlled by three buttons: the Menu button opens the menu and doubles as the Select button. the Step button pages forward through the Menu the Step button. the Step button pages backward through the Menu the Step Back button.
When you first open the Menu, the display will show Menu. Successive presses of the Step button page through the Menu. You cannot go directly to any particular page, but must enter at the top of the Menu and then page through until you reach the page you want. Types of Menu Page There are three types of page in the Menu - Parameter Pages, Information Pages and Test Pages. Parameter pages allow the user to check and also change the current settings of the operating parameters, for example Bright. When a parameter page is displayed, the first press of the Select button shows the current setting. Subsequent presses of the Select button change the page setting. Information pages display information about the unit, for example Software Issue. When an information page is displayed, pressing the Select button displays the information held on that page. Test pages allow the user to initiate a number of useful routines, for example Test. When a Test page is displayed, pressing the Select button starts the test routine. Closing the Menu There are two ways to close the menu and return to normal operation. The easiest way is to wait 5 seconds for the unit to time-out and revert to the standard display. Alternatively, use the Step button to page forward until the display shows End and then press the Select button once. If the unit times out before the operation in hand has been completed, simply reenter the menu, page forward (or backward) and continue where you left off. If you find the 5 second time-out difficult to use, you can extend it by changing the TimeOut setting.

Page 19

Menu Sequence
Use the flow chart (Figure 3) or the Control Summary sheet to guide you through the Menu more quickly. The following explanation deals with the Menu pages in the sequence they 3 occur in the Menu. The use of each page is shown on an individual basis, with the last operation being closing the Menu. After you have become more familiar with the Menu, you will find it more convenient to perform all the Menu operations in one go before finally closing the Menu. SACD/CD Selecting the layer on a hybrid disc With a hybrid disc loaded or playing (the HYBD indicator will be lit), you can select either the SACD or the CD layer using this menu. This duplicates the SACD/CD button on the Remote Control. do this: do this: do this: Open the Menu and step through until the display shows SACD/CD. Press the Select button to flip between SACD or CD. When you have the option you want, wait for the Menu to time-out and the display to revert to its normal mode. If the disc is not a hybrid, the menu will display the disc type but you will not be able to change the setting. Transmit Activating the 1394 Outputs At present, the IEEE 1394 interface supports up to eight active DSD sources at any time. If more are connected to the bus, no more than eight may be active. This situation will improve as industry standards stabilise. The Transmit page allows La Scala to be left in DSD/SACD output mode but with the 1394 interface inactive. With most set-ups, you will not have to worry about this setting. do this: do this: do this: do this: Set up the unit in DSD/SACD mode, with the 1394 interface connected to at least one other unit. Open the Menu and step through until the display shows Transmit. Press the Select button to flip between Active and Inactive. When you have the option you want, wait for the Menu to time-out and the display to revert to its normal mode.
1394 ID 1394 Source Identification This page sets a number between 1 and 8 to identify each La Scala you have connected to the 1394 system. do this: do this: Open the Menu and step through until the display shows 1394ID:x, where x is a number between 0 and 8. Press the Select button repeatedly, allowing the unit to settle for a few seconds each time. The display cycles through 1394ID:0, 1394ID:1,., 1394ID:7, 1394ID:8, and back to 1394ID:0. If you set 1394ID:2 for example, when the DAC is selected to this La Scala, it will display La Scala 2. You can set any other La Scalas connected to the 1394 system to a different number. If you set 1394ID:0, the DAC displays La Scala, without a number.
A minor software update may change the order of the menu items or add an option. If this happens, the Control Summary sheet may be updated before the manual.

dCS Verdi La Scala User Manual dCS Ltd Bright x - Display Brightness
This adjusts the brightness of the main display, with settings between 7 (brightest) and 0 (off, unless something is touched). do this: do this: Open the Menu and step through until the display shows Bright x, where x is a number between 7 and 0. Press the Select button repeatedly and the display cycles through Bright 7, Bright 6,., Bright 1, Bright 0 and back to Bright 7. After time-out, a setting of Bright 0 blanks the display unless the unit is not locked. Operating any control or locking to a source while in this mode turns the display back on momentarily. TimeOut Menu Time Out Setting If you find the 5 second time out period for the menu is too short, use this option to change the time out period to 30 seconds. do this: do this: do this: do this: Open the Menu and step through until the display shows Timeout. Press the Select button once and the display will show Normal. Press the Select button again and the display will change to Long. Repeat this if you want to change back.

Press the appropriate button once. The original software is retrieved from the internal backup while displaying Wait. This may take a few minutes. When recovery is complete, the unit re-boots.

Clocking The sample clock quality significantly determines the output performance of the unit. The highest quality clocks that are available are crystals, so we use these. La Scala uses on-board voltage controlled crystal oscillators (VCXOs) as clock sources. In master mode, this clocks the outputs and controls the mechanism. When slaving to Wordclock In, the VCXO is synchronised to the clock signal extracted from the input by a phase locked loop (PLL). This PLL is of a special narrow bandwidth type, that provides a significant degree of "clock cleaning. The PLL is also very robust, and will lock to very poor signals if necessary.

MAINTENANCE AND SUPPORT

Service & Maintenance
dCS audio products are designed not to need regular maintenance, and contain no user serviceable parts apart from the mains fuse. Obtaining Service If you experience problems with your La Scala, you should check the Troubleshooting section on page 58. You may be able to resolve the situation yourself (for example, by changing a menu setting). If this does not resolve the problem, contact your authorised dCS dealer for advice, quoting the model, the full serial number (see Serial on page 23), the software version number (see Issue on page 23) and giving a detailed description of the fault. If further action is necessary, your dealer will advise you fully.

Mains Fuse

There is a mains fuse below the power inlet, accessible from the outside of the unit. If the fuse blows, it may be changed by the user. The current consumption of the unit is very low, so it only blows if power surges occur, or there is a fault in the unit. Usually, power surges cause no other damage, but if the fuse blows repeatedly on replacement, some other damage will have been done and the unit must be returned to dCS for repair. Fuse Type: 20 x 5mm 0.5 amp T HRC fuse
If the fuse should fail, it is essential that it be replaced with one of the same type and rating. Failure to do so could result in damage to the unit, risk of fire or electric shock and will invalidate the guarantee. x

Replacing a Blown Fuse

Referring to Figure 7, remove the power cable, use a small flat bladed screwdriver to pry up the tab on the fuse carrier (A) and pull it out. Push the blown fuse out of the clip in the carrier (B) and dispose of it. Fit a new fuse in the clip (C) and push the carrier back into the unit so that it clicks home. Spare fuses are provided with the unit.
Figure 7 Changing the Mains Fuse
Disconnect the power cable before changing the fuse.

Page 52

Removing the Transit Screws
