Welcome
We present our flagship upsampling processor: SIRIUS G2.1. 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, 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
system today.
SIRIUS G2.1 improves and optimizes signal from all sources, whether they are high-
resolution files or 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 of using an open standard protocol, SIRIUS G2.1 can also be connected to any
brand of DAC, delivering a variety of sample rates and formats among other functions
and features. SIRIUS G2.1 will provide balance to a world of varied formats, resolutions,
DAC chip topologies and algorithm types.
SIRIUS G2 engineering
The key to these innovations lies in SIRIUS G2.1’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 G2.1’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, as well as Proteus G2 FPGA
co-processing platform. SIRIUS G2.1 also utilizes a triple-channel Purer-Power Supply,
where discrete power supplies are used for the Proteus G2 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 filter groups, providing
four different sound characteristics (Precise, Dynamic, Balance, Smooth) based on the
listener’s personal taste.

Placement and Cabling
Placement
SIRIUS G2.1 should be placed on a solid and stable surface with good ventilation. Do not
install this product near any heat sources such as radiators or other products (such as
amplifiers) that produce heat. Place the product so that its location or position does not
interfere with its proper ventilation. For example, it should not be situated on a bed,
sofa, rug, or similar surface that may block the ventilation openings, or be placed in a
built-in installation such as a bookcase or cabinet that may impede the flow of air
through the ventilation openings.
Ventilation Requirement
SIRIUS G2.1 dissipates up to 40 Watts of power during normal operation. It should
be installed in a space with at least one inch of clearance above, behind and on
both sides of its enclosure to provide adequate ventilation. Avoid placing it
directly above other equipment that produces heat.
Check Your AC Mains Voltage
SIRIUS G2.1 is shipped with its mains voltage preset for operation in the destination
country. The mains voltage setting is written on the back of the unit, besides the power
cord socket. Mains voltage setting is not intended to be changed by the user. If it needs
to be changed, contact your dealer or AURALiC.
The power cord has a three-wire grounding type plug (a plug having a third pin for
grounding). It will only fit into a grounded power outlet. If you are unable to insert the
plug fully into the outlet, contact your dealer or AURALiC. Do not defeat the safety
purpose of the grounded plug.
SIRIUS G2.1 MUST BE USED WITH CORRECT
MAINS VOLTAGE AND PROPERLY EARTHED!
