Description
Leo GX
AURALiC have gone to great lengths to reduce interference and noise within the LEO GX, including the use of optical isolation techniques that keep systems physically separated from each other. Control signals from the processing circuit are sent to the clock circuit via fibre-optic cables instead of electrical pathways, so the source of this impeccable timing is never disturbed.
As digital music formats and system components march ever forward in quality and capabilities, high-end audio systems increasingly rely on the precision of their clocks to keep the digital realm in order.
The greater dynamic range of high resolution files can only be realised with the help of modern clocks, capable of working frequencies nearly 10x higher than what was common just a handful of years ago. However, today’s high-frequency DAC clocks are costlier and much harder to design and build than ever before.
Leo GX hardware starts with two temperature-controlled rubidium atomic reference clocks. Each is paired with an oscillator using stress compensated cut crystals, for thermal and mechanical resilience and low phase noise performance. The result is remarkably high signal frequencies: 90.316 MHz for 44.1-based audio signals, and 98.304 MHz for 48K-based signals.
Leo GX is contained in a one-piece chassis designed specifically for the premium lineup of AURALiC G Series devices. This so-called Unity Chassis is machined from a single billet of aluminium that provides Leo GX with superior shielding from EMI noise, creating an ultra-precise, high frequency feed that can take the performance of your G system to new heights.
