Vivaldi APEX DAC Key Features

  • 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

Vivaldi APEX DAC Specifications

Converter Type
dCS proprietary Ring DAC™ topology, with a choice of 3MHz or 6MHz operation

Analogue Outputs
1 x pair balanced outputs on 2x XLR connectors. Output levels: 0.2V, 0.6V, 2V, 6V rms for a full-scale input, set in the menu. Output impedance: 3Ω. Maximum load: 600Ω (10k-100kΩ is recommended); 1x pair unbalanced outputs on 2x RCA connectors. Output levels: 0.2V, 0.6V, 2V, 6V rms for a full-scale input, set in the menu. Output impedance: 52Ω. Maximum load: 600Ω (10k-100kΩ is recommended)

Digital Inputs
USB 2.0 interface on B-type connector, accepts 24-bit 44.1 – 384kS/s PCM, DSD/64 & DSD128 in DoP format; 4x AES/EBU inputs on 3-pin female XLR connectors, accepts 24-bit 32 – 192kS/s PCM & DSD/64 in DoP format; 2 x Dual AES pairs, accepts 24-bit 88.2 – 384kS/s PCM, DSD/64 & DSD/128 in DoP format; 2 x SPDIF on RCA Phono connectors, accepts 24-bit 32-192kS/s PCM & DSD/64 in DoP format; 1 x SPDIF on BNC connector, accepts 24-bit 32-192kS/s PCM & DSD/64 in DoP format; 1 x SPDIF on TOSLINK connector, accepts 24-bit 32 – 96kS/s PCM; 1 x SDIF-2 interface on 2x BNC connectors, accepts 24-bit 32 – 96kS/s PCM or SDIF-2 DSD (auto selected). This interface requires a compatible Word Clock input, locked to the correct data rate

Wordclock I/O
3 x Word Clock Inputs on BNC connectors, accept standard Word Clock at 32, 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as the clock rate or an exact multiple of the clock rate. Sensitive to TTL levels; 1 x Word Clock Output on 1x BNC connector. With Sync Mode set to Master, a TTL-compatible 44.1kHz Word Clock is output. In Universal Master Mode, a 38.4kHz Word Clock is output for use with the Vivaldi Upsampler

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

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), plus Filter 5 which has an improved transient response

Software Updates
Loaded from CD-R via PCM inputs or PC via USB interface

Local Control
dCS Universal Remote is supplied as standard. RS232 (controlled by the Vivaldi Upsampler / app or a third party device)

Power Supply
Factory set for 100, 115, 220 or 230V AC, 50-60Hz

Power Consumption
23 Watts typical/50 Watts maximum

2023 Price

£38,500
