AURALiC SIRIUS G2 Upsampling Processor - Available with Online Finance and Free Delivery from Vickers HiFi - York.
The AURALiC SIRIUS G2 upsampling processor operates on an open standard, allowing music lovers to upgrade both the processing power and the original performance envelope of their Digital-to-Analogue Converters (DACs), whether they’re using an Auralic branded DAC, or one developed by another manufacturer.
The AURALiC SIRIUS G2 shoulders the data processing burden typically handled by a DAC. This outsourcing of processing duties dramatically reduces the amount of distortion and jitter typically passed into the conversion stage, thereby allowing the DAC to be fed a pure, efficient, and low-distortion stream of digital data. The measurements of this reduction in noise are well beyond what is currently available from other manufacturers.
Since most DAC chips have been designed to work best in a particular mode (DSD128 or PCM in 192 kHz, as examples), not necessarily the highest or lowest possible resolution, SIRIUS G2 will optimize and improve the performance of any DAC in its native or most comfortable “Sweet Spot,” fulfilling the DAC’s potential, no matter the incoming resolution of the file being played back.
SIRIUS G2 delivers to the DAC a wide variety of resolutions and formats and can accept any input data with sampling rates from 44.1 kHz to 384 kHz in PCM, or DSD64 to DSD512. Inputs and outputs onboard SIRIUS G2 are varied and plentiful. Standing apart from its peers, SIRIUS G2 can output USB, in any format, including PCM in 384 kHz and DSD512 with extremely low distortion. This increased flexibility adds yet again to the list of the number of DACs eligible for optimization and enhancement provided by SIRIUS G2.
The key to these innovations lies in SIRIUS G2’s state of the art AURALiC Proteus G2 Co-Processing Platform; which harnesses a Xilinx XC7A200T FPGA chip at its heart, bolstered by 512 MB of DDR3 memory. This FPGA chip contains more than 200,000 logic cells and 740 DSP slices, all combining to provide unparalleled levels of data processing capability. SIRIUS G2’s computational power and efficiency are achieved in part because of the design decision to employ a dual-processing platform structure, while an AURALiC Tesla G1 handles hardware control, an AURALiC Proteus G2 focuses all of its efforts on music data processing.
USB and other digital outputs are protected by Dual Galvanic Isolation. Dual Femto clocks are employed for the USB and other digital outputs. SIRIUS G2 also utilizes a triple-channel Purer-Power Supply, where discrete power supplies are used for the Proteus G2 FPGA co-processing platform, the general data processing circuit, and the audio circuit. Flexible Filter Mode is also included, allowing the user to select from four different digital filters, providing four different sound characteristics based on the listener’s personal taste.
As with other G2 products, Lightning Link, a proprietary, high-speed(18Gbps), bi-directional communications protocol used for both control and signal functions can be used for jitter-free transmissions with ARIES G2 and VEGA G2.
Additional options being offered by SIRIUS G2 include a 20 band EQ and speaker placement compensation feature. In the future, an over-the-air firmware update will provide a convolution engine for advanced room correction.
