Reference Master Clock
LEO GX is a breakthrough in digital audio system clocking.
Comprehensive features & functions
The first master clock ever that can feed a DAC directly with a working signal so precise we had to use new benchmarks to measure its performance. Wider staging, pinpoint locational accuracy, and an expanded dynamic range are just some of the benefits you’ll hear when you implement LEO GX’s one-of-a-kind approach to clocking that literally bypasses the traditional limitations of internal DAC clocks.
A Breakthrough in Digital System Clocking
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 for example is only realized with the help of modern clocks that are capable of working frequencies nearly ten times 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.Designed for ease of use, crystal-clear sound and a highly flexible system configuration, ALTAIR G1 brings high-performance, cutting-edge technology, and incredible value to any high-fidelity music system.
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 the LEO GX’s remarkably high signal frequencies: 90.316MHz for 44.1-based audio signals, and 98.304MHz for 48K-based signals.
We’ve gone to great lengths to reduce interference and noise in the new 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 fiber optic cables instead of electrical pathways, so the source of LEO GX’s impeccable timing is never disturbed.
Designed specifically for the premium lineup of AURALiC G Series devices, the Unity Chassis is machined from a single billet of aluminum that provides the LEO GX with superior shielding from EMI noise. It’s the perfect working environment to create the ultra-precise, high frequency feed that can take the performance of your G system to new heights.
LEO GX internal circuits are physically distributed to enhance overall balance and performance. And its specially designed foot spikes dampen and absorb vibrations so the operation of its internal clock always starts with a rock-steady foundation.
Dual Purer-Power Linear Power Supplies
We’ve given the LEO GX two of our ultra-quiet Purer-Power linear power supplies, galvanically isolating them from each other in the obsessive quest to reduce noise and create a pristine working environment. One Purer-Power supply feeds the LEO GX’s processing system, while the second powers the clock circuit. Interference between the areas is reduced to minimum, so there’s nothing to get in the way of LEO GX’s stellar performance.
Realize Full Potential
The LEO GX is such a precise clock, running at very high frequency, you will need the best interconnect cable to realize its full potential. We created a cable specifically for LEO GX, made from 60GHz bandwidth military aerospace-grade material and connectors. Handmade and precisely tuned, it comes with a performance data report so you can be sure its specs are well capable of the task at hand.
