The Auralic Sirius G2.1 Upsampling Processor stands as the fourth addition to the award-winning G2.1 Series of AURALiC products. The Sirius G2.1 improves and optimises signals from all sources, whether they are high-resolution files or streams from an inferior source or format.

With the SIRIUS G2.1, compressed, lossy, and poor recordings all have the potential to be improved, thereby upgrading your overall experience. Because SIRIUS G2.1 utilises an open standard protocol, it can also be connected to any brand of DAC. This delivers 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 optimises 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,” 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.

Optimise by Equalising

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 8-band parametric equaliser feature, allowing you to optimise for your environment without spending tens of thousands on a complete room build or renovation.

Perfect the Imperfect

SIRIUS G2.1 offers a speaker placement function to compensate for real-world problems, allowing you to deal with barriers to perfect sound in the digital domain. While it’s necessary to place your speakers as best you can in the room first, our speaker placement function could mean the difference between poor and great sound in a less-than pristine environment.

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.

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.
