SIRIUS G2 Press Release

Hello AURALiC Community,

We are proud to introduce the SIRIUS G2 Upsampling Processor.

Below you’ll find the full press release on our newest product:

AURALiC Debuts SIRIUS G2 Upsampling Processor at Munich High-End 2019

Munich May 8th, 2019 – Cementing its reputation for developing high-performance digital sources, AURALiC will unveil a new addition to the award-winning G2 Series of products at the Munich High-End Audio show this year. Three years in the making, the SIRIUS G2 Upsampling Processor will debut at the MOC venue in Munich from May 9th to May 12th at Atrium 4 2.0G E211.

SIRIUS G2 operates on an open standard, allowing music lovers to upgrade both the processing power and the original performance envelope of their Digital-to-Analog Converters (DACs), whether they’re using an AURALiC branded DAC, or one developed by another manufacturer.

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.

SIRIUS G2 engineering

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, anAURALiC 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.

AURALiC Proteus G2 Co-Processing Platform

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.

SIRIUS G2 EU Retail will be €6,299, UK Retail will be £5,499, US Retail will be $5,999, and will be available for purchase in July/August 2019

can sirius g2 be a streamer?i see Sirius have lan

#5

No the LAN port is only for firmware update like the Leo

#7

So the same 4 filters the Aries has but with the ability to output DSD?

Pretty vague on the details. What does it do better and why?
