dCS Vivaldi Upsampler

Sample it up

Vivaldi Upsampler is designed to act as the hub of a digital audio system and will transform your listening experience, taking your music collection to levels you have not heard before.

Operating as a digital-to-digital converter Vivaldi Upsampler accesses music from any digital source and converts the audio from its native sample rate to either high resolution DXD (24 bit data at 352.8 or 384 kS/s), DSD (1 bit data at 2.822 or 3.07MS/s) or standard high resolution PCM (24 bit data up to 24/192kS/s). The results gained from Vivaldi Upsampler are extraordinary – a more vibrant, 3-dimensional, transparent and effortless performance.

Vivaldi Upsampler features a wired network connection and can stream high resolution audio files stored on a computer or on network storage via UPnP™. The additional asynchronous USB input on Vivaldi Upsampler also allows direct connection of a PC and supports high resolution audio up to and including 192kS/s and DSD over USB. The USB interfaces run in an Asynchronous USB mode, which makes Vivaldi Upsampler immune to jitter from the typical computer’s noisy clock.

Vivaldi Upsampler is Apple Authenticated and supports playback of iPod/iPhone-stored digital media, bypassing the iPod/iPhone internal DAC to ensure optimal performance. USB memory hardware is also supported.

An array of independently selectable digital inputs (RJ45, USB, AES, SPDIF, SDIF-2, Toslink) completes the versatility
of this powerful machine and elevates the performance of Red Book CD from CD Players or high resolution audio from digital streamers to a previously unsurpassed level.

dCS were pioneers in the use of external clocks in digital audio systems and the redesigned multi-stage Phase-Locked-Loop (PLL) system used in Vivaldi Upsampler sets world-beating standards for accuracy and control of troublesome jitter from the incoming audio stream.

The dCS ‘soft’ approach to programmable logic makes it extremely easy for users to update Vivaldi Upsampler software, whether adding new features, installing performance upgrades or adapting to changes in digital formats.

Used as part of a complete Vivaldi digital audio playback system Vivaldi Upsampler gives a performance of effortless realism each and every time.

Key Features

Utilising the latest generation dCS Digital Processing Platform which offers stateof-the-art measured performance and unrivalled musical experience.

Designed for maximum flexibility as output configuration can be optimised in systems with a variety of digital audio sources.

Dual crystal oscillators with microcontrollerenhanced temperature correction.

New auto-clocking mode used in the Vivaldi range improves ease of use and minimises jitter.

Improved power supplies give lower running temperature and improved tolerance to AC supply variations.

Multi-stage regulation ensures sensitive analogue circuitry is not affected by digital interference.

Aerospace grade machined aluminum chassis fitted with tuned acoustic damping panels reduces magnetic effects
and vibration.


Digital-to-Digital Converter.

Converter Type
dCS proprietary Ring DAC™ topology.

Digital Inputs
Network interface on an RJ45 connector – Acts as UPnP™ renderer and streams digital music from a NAS or local computer over a standard Ethernet network, decoding all major lossless formats including FLAC, WAV, AIFF, WMA up to 24 bit 192kS/s native sample rate. Other supported file formats include ALAC, MP3, M4a, AAC and OGG. Some formats are limited to lower sample rates.

USB 2.0 interface on a type B connector. Operates in Asynchronous USB mode, Audio Class 1 or Class 2. Class 2 mode will accept up to 24 bit PCM at 44.1, 48, 88.2, 96, 176.4 or 192kS/s and DSD in DOP format.
USB-on-the-go interface on A-type connector, streams audio files from a USB flash drive or iPod/iPhone. Will accept up to 24 bit PCM at 44.1, 48, 88.2, 96, 176.4 or 192kS/s and DSD in DOP format. Operates in asynchronous USB mode.

AES3 on a 3-pin female XLR connector.

4x SPDIF on 2x RCA Phono, 1x BNC connectors and 1x TosLink optical connector.

1x SDIF-2 PCM interface on 2x BNC connectors + Word Clock

All electrical digital inputs will accept PCM data at up to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4 or 192kS/s. The Toslink input and SDIF-2 interface are limited to a maximum of 96kS/s.

Digital Outputs
2x AES3 on 3-pin female XLR connectors. Each outputs 24 bit PCM at 32, 44.1, 48, 88.2 or 96kS/s, OR as a Dual AES pair at 88.2, 96, 176.4, 192, 352.8 or 384kS/s or dCS-encrypted DSD.

2x SPDIF on RCA Phono and BNC connectors. Each outputs 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4 or 192kS/s.

Data from any input may be converted to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4, 192, 352.8 or 384kS/s or DSD (1 bit data at 2.822MS/s). The output sample rate must be equal to or greater than the input sample rate.

Word Clock I/O
Word Clock input on 2x BNC connector. Accepts standard Word Clock at 32, 44.1, 48, 88.2, 96, 176.4 or 192kHz. Sensitive to TTL levels.
Word Clock output on 1x BNC connector. Outputs standard Word Clock at a frequency equal to the (single wire) output data rate, or 44.1kHz when set to output DSD.

Spurious Responses
Better than -100dB0 @ 20Hz-20kHz for Fs> 32kS/s, 20Hz-14kHz for 32kS/s.

A choice of filter responses give different trade offs between Nyquist image rejection and the phase response.

Software Updates
Loaded from CD-R via PCM audio input or via USB.
