Auralic SIRIUS G2.1 Upsampling Processor

As a specialized enhancement product, SIRIUS G2.1 stands as the fourth addition to the award-winning G2.1 Series of AURALiC products. As a system, the G2.1 stack, comprised of ARIES G2.1, VEGA G2.1, LEO GX.1 and SIRIUS G2.1 now represent one of the most advanced digital sources available for your high-performance system today. SIRIUS G2.1 improves and optimizes signals from all sources, whether they are high-resolution files or streams from an inferior source or format. With SIRIUS G2.1, compressed, lossy, and poor recordings all have the potential to be improved, thereby upgrading your overall experience. Because SIRIUS G2.1 utilizes an open standard protocol, it can also be connected to any brand of DAC, delivering a global variety of sample rates and formats among other functions and features.  SIRIUS G2.1 will provide universal balance to a world of varied formats, resolutions, DAC chip topologies, and algorithm types.

A Universal Approach to High-Performance Across All Formats

SIRIUS G2.1 stands to improve your listening experience by employing advanced processing techniques. Poorly made recordings and even early digital recordings can benefit from SIRIUS G2.1’s impressive processing firepower. This process optimizes less-than pristine recordings by resampling the signal in a manner that potentially improves upon the experience of listening to an inferior recording.

Getting the Most From Your DAC

All DACs are built with a “sweet-spot,” a point where each DAC circuit excels at a resolution or format. DAC circuits built for DSD playback sound better when playing DSD and PCM DAC topologies perform better when fed PCM. By resampling to a format within the DAC’s “sweet spot,” the chip is allowed to play to its strengths, by lessening the processing requirement of the DAC.

A World First

SIRIUS G2.1 provides multiple inputs and outputs, allowing you to connect to a variety of digital sources and DACs. AURALiC’s spirit of innovation continues to put forth market-first features, as exemplified by SIRIUS G2.1’s unique ability to deliver an upsampled DSD signal to any compatible USB DAC, the first product in the world to do so.

Optimize by Equalizing

The most important factor affecting the quality of playback in your system is not the cables, components, or speakers, but instead the room in which you play your music. SIRIUS G2.1 can compensate for the room with its 20-band parametric equalizer feature, allowing you to optimize for your environment without spending tens of thousands on a complete room build or renovation.

Perfect the Imperfect

The most important factor affecting the quality of playback in your system is not the cables, components, or speakers, but instead the room in which you play your music. SIRIUS G2.1 can compensate for the room with its 20-band parametric equalizer feature, allowing you to optimize for your environment without spending tens of thousands on a complete room build or renovation.

Resample Your Experience

All digital products contain some form of sampling engine. As a separate device, SIRIUS G2.1 sets itself apart by focusing all of its energy on digital signal processing strength, using advanced resampling techniques to convert between any and all sampling rates. You’ll be able to further customize the sound of your digital sources when you choose from four distinct digital filters thanks our very own Flexible Filter Mode Technology. All of the above is done with uncommonly low distortion levels, potentially down to a staggering -170dB, which will also help keep the SIRIUS G2.1 virtually invisible in the signal path.

The Power of Digital Processing

SIRIUS G2.1 is powered by the 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 G2.1’s computational power and efficiency are achieved in part because of the design decision to employ a dual-processing platform structure, which doubles capacity. While an AURALiC Tesla G1 handles hardware control, the Proteus G2 focuses its efforts on music data processing.

Unity Chassis II

The SIRIUS G2.1 chassis has been designed as a double enclosure, where an outer case made from high-grade aluminum is supplemented with an inner layer of copper. A high-mass base and enhanced four-foot multi-spring suspension system complete the quiet, noise defeating performance of the SIRIUS G2.1’s Unity Chassis II.

Perfectly Balanced

SIRIUS G2.1 internal circuits are physically distributed to enhance overall balance. And with specially designed foot spikes that dampen and absorb vibrations, the SIRIUS G2.1 is always rock-steady, for ultra-smooth signal delivery.

Beautifully quiet

The SIRIUS G2.1 introduces sophisticated galvanic isolation and Unity Chassis II techniques that drastically reduce the potential for electro-magnetic interference, for an extraordinarily pure, clean sound. Precise re-clocking reduces jitter, and brand-new galvanic isolation provides even more protection against EMI noise. The result is a whopping 80% reduction in noise levels.

More to Control

Smart-IR is just that – a smarter solution for controlling your SIRIUS G2.1. As with all AURALiC products, Smart-IR allows you to control certain functions of the SIRIUS G2.1 from any number of different remotes you already own. For example, you may program a remote to quickly switch between the four different digital filters by assigning a filter to individual buttons on that remote. This function is easily accessible in the SIRIUS G2.1 menu structure and provides you with yet another way to control not just SIRIUS G2.1, but your entire G2/2.1 stack.
