Description

Triple Femto Clocks
Triple Femto Clocks have got you covered no matter how you like to connect. With 3 separate, super-accurate clocks cycling on the order of quadrillionth of a second, you’ll enjoy extremely low jitter and better sound. First clock takes care of digital outputs, the second regulates USB output and the last clock feeds the Proteus G2 processing platform. You can be sure your musical signal is always rock-steady.

Galvanic Isolation
SIRIUS G2.1 is equipped with two sets of high-speed galvanic isolators, between the processing platform and its audio circuits. Data can flow across the isolator, even while it physically separates and shields the audio circuits from interference. 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.

Flexible Filter Mode
Flexible Filter Mode gives you a nuanced level of control over your audio output. Its various modes were developed using a combination of objective data models and subjective testing, with each mode offering a unique array of filters to match the sonic quality of the source. Whether it’s modes to tweak in-band ripple, out-band attenuation, ultrasonic filtering and more, you’ve always got the power to dial in the performance you want.

Triple Purer-Power
The Purer-Power linear power supply reduces DC current noise by as much as 90dB with its power purification module. Using a specially designed transformer and unique wiring that minimizes vibration, noise from Purer-Power is kept below 1uV across the audible spectrum, leaving you to discover the details in your music, down to the last bit.

Smart-IR Control
Smart-IR Remote Control lets your AURALiC device map its functionality onto any remote you’d like. Just let the device know which remote you prefer, and all of its operations. Changing of processing functions, volume, filter mode and more can be assigned to buttons just the way you like them.

User's guide


* SIRIUS G2.1 USB Audio input does not require driver for Mac OS X and Linux system. AURALiC USB Audio Driver is high recommended for use with Windows system. DSD512 is not supported by Mac OS X.
** USB DAC needs to be compatible with Linux system. DSD512 can only be output via native DSD format because the maximum DoP output rate is limited to DSD256. Please check with your DAC's compatibility.
*** All tests are processed under "Precise" filter mode.
**** All signals coming from any input will first be converted into a high frequency multi-bit data stream for jitter removal and for any user-enabled processing. The processed data will then be resampled to the customer’s selected output frequency and then be sent out of SIRIUS G2.1. This processing structure means SIRIUS G2.1 does not have a passthrough mode and will not passthrough MQA content.
