dCS Vivaldi APEX DAC
Reference State of the art D/A Omvandlare via dCS Ring DAC - en FPGA baserad DAC med unik arkitektur och ultra hög bandbredd utan motstycke. Digital Volymkontroll.

Höjdpunkter:
• dCS Ring DAC APEX™ hardware further reduces distortion and improves linearity for enhanced musical performance
• Utilises the latest generation dCS Digital Processing Platform for state-of-the-art measured performance and unrivalled fidelity
• Designed for maximum flexibility by accepting audio data from a variety of digital sources
• Flexible output configuration can be optimised in systems with or without preamplifiers
• Comprehensive clocking architecture plus an auto-clocking mode used in the Vivaldi range improves ease-of-use and minimises jitter
• USB interface allows easy connection to a computer, accepting PCM data at up to 24/384 and DoP (DSD/64 or DSD/128 over PCM)
• The interface runs in asynchronous USB mode, making the DAC immune to jitter from noisy computer master clocks
• Improved power supplies give lower running temperature and superior tolerance to AC supply variations
• Multi-stage regulation ensures sensitive analogue circuitry is unaffected by digital interference
• Separate power circuits for the digital and analogue sections further enhance the purity of the power supply
• Aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels reduces magnetic effects and vibration
• Features a full MQA™ decoder. This MQA™ implementation is unique, as it is the first opportunity to enable a DAC which, by providing exact rendering to beyond 16x (768 kHz), matches the desired temporal response with very low modulation noise

Specifikation

• Typ: Digital-to-Analogue Converter
• Converter: dCS proprietary Ring DAC™ topology, with a choice of 3MHz or 6MHz operation
• Residual Noise: Better than -113dB0 @ 20Hz-20kHz unweighted (6V setting)
• L R Crosstalk: Better than -115dB0, 20-20kHz
• Spurious Responses: Better than -105dB0 @ 20-20kHz
• Software: Loaded from CD-R via PCM inputs or PC via USB interface
• Control: dCS Universal Remote is supplied as standard. RS232 (controlled by the Vivaldi Upsampler / app or a third party device)
Filters:
• PCM mode: 4 filters give different trade-offs between the Nyquist image rejection and the phase response.
• 2 extra filters are available at 44.1, 176.4, 192, 352.8 and 384kS/s. DSD mode:
• 4 filters progressively reduce out-of-audio band noise level (inherent in the 1 bit nature of DSD)
• Filter 5 which has an improved transient response
