AURALIC ALTAIR G2.2 Streamer DAC

With the Altair G2.2, Auralic offers a new version of its streamer that also functions as a DAC and preamplifier. The additions in version 2.2 include a dual clock with an updated dedicated power supply, galvanic isolation between the different stages of the device to drastically reduce background noise, and a new version of the streaming platform.

Altair G2.2: DAC fusion

The digital/analogue conversion stage of the Altair G2.2 is based on an architecture developed by Auralic called "DAC fusion". This hybrid architecture between the ladder resistor network and the delta-sigma modulator allows you to benefit from features such as clock signal reconstruction, digital filters and oversampling, while leaving the final conversion to the R2R network, so you can enjoy superb sound quality.

Altair G2.2: Tesla G3

Built on a 64-bit quad-core architecture, the Tesla G3 streaming platform offers eight times the processing capacity of its predecessor. Equipped with 4GB of DDR4 system memory, the Tesla G3 can easily handle the most demanding processing tasks, making it a future-proof solution that will adapt to the rapidly changing digital audio landscape.

The Tesla G3 platform also uses Direct Memory Access (DMA) technology for its audio input and output channels, allowing all audio-related hardware and software to access system memory directly, dramatically reducing latency and jitter by 90% compared to Tesla G2.

Altair G2.2: Galvanic insulation

To keep the clock signal, power supply and input signal clean, the Altair G2.2 incorporates multiple high-speed galvanic isolators positioned between the Tesla G3 platform and the ultra-sensitive audio circuitry. These isolators provide total physical separation and protection against interference, shielding the DAC from potential noise while allowing smooth data transfer.

Altair G2.2: Auralic Lightling DS

The Altair G2.2 can easily be controlled remotely using Auralic's proprietary Lighting DS application. This application, exclusive to IOS, lets you play music from multiple sources, including local files, seamlessly, thanks to an elegant, ergonomic interface.

Altair G2.2: CD playback and ripping

The Altair G2.2 also offers the option of connecting a USB CD drive to the Altair G2.2 to either simply play CDs or extract data from them. Furthermore, when reading a CD, the Altair G2.2 applies the same treatment to the data as when used as a streamer, reading and re-comparing the data in cache before sending it to the rest of the system. The result is the elimination of potential transport-induced jitter, negating any negative effect of the quality of the chosen CD player.
