How do I use the Dual AES DSD interface in a full Scarlatti / Paganini system?

If your system does not include an Upsampler, set the Transport to Vivaldi Mode and connect the Dual AES out to the DAC.
The Scarlatti & Paganini DACs have only one Dual AES input, so you will need to decide which source is most important to you when setting up a full system.
– If your priority is SACD, use Dual AES from the Transport with Vivaldi Mode tuned on. For CD playback, use 1394 from the Upsampler.
– If your priority is CD, use Dual AES from the Upsampler. For SACD playback, use 1394 from the Transport.
In both cases, make sure the system is correctly clocked.

How can I arrange service for the Pronto or Nevo remote supplied with my Scarlatti Transport?

At present, we can arrange servicing through the UK companies that originally supplied the remote to us. Please contact us stating the model, the remote serial number, the serial number of the dCS product with which it was purchased and a full description of the fault. Please do not return the unit to us until we have given you a returns number. dCS acts as an intermediary only, any warranty for the repair (parts and labour only) is provided by the servicing company.

What can I do if Windows XP reports “Unknown Device” when I connect a different dCS USB device to the PC?

This is a bug specific to Windows XP, it can occur if the PC is connected to a different model to that used for the driver installation. Either re-install the driver or follow these steps:
– Go to Start > Control Panel > System > Hardware > Device Manager.
– Under “Sound, Video & Game Controllers”, find the “USB Audio Device” with an exclamation mark (!) next to it. Right-click on it, choose “Update Driver”.
– Select “No, not this time”, click Next.
– Select “Install from a list or specific location”, click Next.
– Select “Don’t search. I will choose the driver to install”, click Next.
– Select the dCS driver from the list, click Next.
– A “Hardware Installation” warning window will pop up, click “Continue anyway”.
– Another Hardware Update Wizard will appear. Choose “No, not this time” then “Install the software automatically”. – Click “Continue anyway” when asked.
This long sequence makes sense when you actually do it!

Why did you not respond to my email?

We aim to respond to ALL email or website enquiries within 2 working days. We do not deliberately ignore any genuine enquiries. Very occasionally, we receive an enquiry that states an invalid email address or we find our response bounces. In such cases, we will try to follow up by phone or post if possible. If we do not have usable contact details, we have no way to respond!

Which Filter settings do you recommend?

This is very hard to answer. The sound presentation for each Filter depends on the type of music being played, how it was recorded, the amplifier, the loudspeakers, the room and – most importantly – the preferences of the listener. The manuals contain SUGGESTIONS for Filter settings, but they are no more than that. Filter settings really are a personal choice.

Can I rename the DAC and Upsampler inputs to something more useful?

The Vivaldi DAC and Upsampler’s inputs can be given a name with up to 8 letters or numbers. You will need a computer with a USB port, a USB-RS232 adapter cable and a terminal program such as TeraTerm or PuTTY. Please see the manuals for detailed instructions.

How can I get the upsampling license code for my Puccini Player?

The license code is supplied free to the original owner of Puccini Players shipped from dCS from 1st April 2009 onwards when we receive the warranty registration.

For subsequent owners or for Players shipped before this date, there is a charge of GBP 350 (+ 20% tax in the EU). Contact us, stating your name, address, the Player’s serial number and the date you bought it. The code is keyed to the serial number. We aim to respond within 2 working days.

Playing DSD files from a NAS drive running Minimserver, why does the sound drop out periodically?

This can happen if you play a DSD file and then (at some point) change the frequency of the clock to which the Upsampler’s Network interface is locked. As the Network interface is asynchronous, this change seems to throw Minimserver’s DoP packaging routine out of sync. The solution is to re-boot the NAS drive. If you want to experiment with different clock frequencies, we suggest that you disconnect the Network cable from the Upsampler first.

Can I play DSD/64 DFF or DSF files over the network to the Vivaldi Upsampler?

Yes, provided the server software packages the DSD data in DoP format. Minimserver and JRiver Media Center work well. Vivaldi does not support DSD/128 playback at present.

Can I use a Linux PC or a Linux-based server with your USB products?

We test our products thoroughly with Windows and Mac OSX, but only briefly with Linux Ubuntu. As Linux is open-source, it tends not to be as thoroughly tested as commercial operating systems, so we cannot offer support if you encounter problems. Linux natively supports USB Audio Class 1 and 2, so there is no need for a special Linux driver.

Can I use a different UPnP control point App to send music to the Vivaldi Upsampler?

Yes, in principle you can use any UPnP control point App. Note that the remote control features (e.g. DAC volume control) are available only from the dCS App. We cannot accept responsibility for other manufacturer’s software, of course.

My satellite receiver has a Toslink optical output only. How can I connect it to my dCS system?

Debussy, Puccini and Paganini do not feature Toslink inputs, but adapters are widely available. Please consult your dealer or search online for “toslink to spdif converter”.

Why do the displays of my Vivaldi units refresh themselves every 10 to 20 seconds?

On Vivaldi systems, this can happen if there is a set-up error in the clocking system, generally either

(1) locking the DAC/Upsampler to the Master clock but not the Transport or other source or

(2) locking the source device to the Master Clock but running the DAC in Master Sync Mode.

The Sync Mode icon on the displays should help you find the error. Please correct the clock connections or the DAC/Upsampler’s Sync Mode settings.

Can I upgrade the hardware in my dCS products to the latest version?

Hardware upgrades are currently available for dCS units with serial numbers starting with DDC, PUU, SCK and PCK. Upgrading the P8i Player to the Mk2 version is still available in some territories. Most hardware upgrades can be fitted by your authorised distributor. All hardware upgrades are chargeable and are subject to availability.
Sorry, we cannot offer hardware upgrades for the Classic range (made before 2007).

Do your USB interfaces work with all versions of Mac OSX?

We have tested our products with all versions of OSX up to the current OSX 10.10 Yosemite without problems. We use industry standard USB audio interfaces, so any problems experienced after a major OSX upgrade should be resolved by a subsequent minor OSX update.

A disc gets stuck in the Player when I select the digital inputs.

When the Player is not in Disc mode, the CD mechanism is turned off to reduce electrical noise and improve the sound quality. Please eject the disc and close the tray before selecting the digital inputs.

After changing the Puccini Player’s Source from SPDIF to Disc, why is there is no sound from the Player?

When using the digital inputs, the Stop / Eject button is used for Muting. If you mute the Player before changing input, it will remain muted – this will be indicated by the blue Mute LED beside the Stop / Eject button. Press the Mute button on the remote control to unmute the Player.

Why does the Filter setting change when I change input?

The Filter setting is stored separately for each sample rate. If you select a source with a different sample rate, the Filter setting you previously selected for that sample rate will be applied.

How do I update the software in my Puccini U-Clock?

The Puccini U-Clock was deliberately designed to be simpler than our other products, so it has no software update feature. Updating requires opening the case and loading new software from a chip, please contact your dealer or distributor to arrange this.

Can I update dCS products that do not have a USB interface using a PC?

It is possible to update most other dCS products from a PC via USB and a U-Clock or Upsampler, except for Transports and Players. The PC must be set to output bit-perfect data – there must be no volume adjustment, re-sampling to 24 bits, fade in/out or sample rate conversion. A U-Clock can be used directly via it’s SPDIF output. An Upsampler must be set to output 44.1kS/s, with Clone mode set to on.
