Users have the option to disable the preamplifier function through software and reduce the output level to 2V, allowing for seamless integration with external preamplifiers.
AURALiC's proprietary Direct Data Recording (DDR) technology records audio data directly into Tesla G3's system memory in binary format, and then processes and outputs it to the DAC with dual 60fs Femto Clock - one for 44.1x and another for 48x sampling frequencies, serving as a master clock independent of the input signal. Thanks to these cutting-edge technologies, VEGA S1 is immune to input signal distortion and jitter, delivering unmatched sound quality. Experience an unparalleled listening journey with stunning detail, clarity, and precision, free from any distortion or jitter.
In the pursuit of exceptional dynamic range that unveils intricate details in original recordings, modern high-end DACs demand utmost cleanliness in clocks, power supplies, and signal feeding. The VEGA S1 meet this challenge by incorporating high-speed galvanic isolators, strategically positioned between the Tesla G3 processing platform and the ultra-sensitive audio circuit. These isolators ensure complete physical separation and protection against interference, safeguarding the DAC from any noise coupling while enabling seamless data transfer. With these advanced features, the VEGA S1 deliver unparalleled audio clarity and precision, revealing the true essence of your music.
