AURALiC Tesla Platform
ALTAIR is powered by AURALiC's proprietary Tesla hardware platform that includes a Quad-Core Coretex-A9 processor running at 1GHz, 1GB DDR3 onboard memory and 4GB system storage. The Tesla platform has a calculation ability of 25,000 MIPS, more than enough to decode a vast spectrum of audio formats, including AAC, AIFF, ALAC, APE, DIFF, DSF, FLAC, MP3, OGG, WAV, WV and WMA. AURALiC has chosen this platform for its flexibility and long term support consideration. Future features planned include DSD Upsampling, Room Acoustic Treatment. All these features can be delivered through automatic online updates without user’s attention.
Femto Master Clock
The dual-frequency Femto Master Clock inside the ALTAIR is specially designed and optimized for its ESSSabre DAC chip: with one frequency for playing music with a sampling rate which is the multiple of 44.1K, and a second for 48K, making it possible for the ALTAIR to be able to lock on with highest clock precision (equal to the VEGA’s “EXACT” mode) at all time without dropouts. The Femto Master Clock, which is powered by a 9uV extremely low noise dedicated power supply, has a very low phase noise performance. It not only has dramatically low phase noise, which is only at-151dBc/Hz level, but also an excellent 100Hz offset noise level which is only -115dBc/Hz. Driven by such a high performance clock, the ALTAIR can bring you vivid music with natural detail and a solid sound image.
Full Linear Power Supply
With more and more DACs at this price range starting to use switching power supplies, AURALiC insists on using high performance but costly Purer-Power™ linear power supply technology on the ALTAIR. With this technology, the dirty AC power firstly goes into a power purification module, and the DC current and noise from both within and outside audio frequencies can be reduced by as much as 90dB. The purified AC power is then feed to a high quality transformer, with a specialty iron core made toAURALiC’s specifications, and unique wiring to ensure zero vibration and very low noise to avoid impacting the sensitive audio electrical circuit.Compared to the conventional switching power supply which generates wide-band noise that is hard to eliminate, AURALiC’s discrete component- based power supply feeds the DAC chip’s analog circuit with an astonishing low noise that is below 1uV (1uV = 0.000001V) within the entire audio band, making ALTAIR a perfect tool to re-discover your music with more details in the “last bit” that you may never noticed before.
Flexible Filter Mode
ALTAIR has four built-in filter modes which allows its user to customize sound best befitting their personal preference. Those filter modes were developed fromAURALiC’s well known Flexible Filter Mode in the VEGA Digital Audio Processor, with each containing several digital filters optimized for a corresponding sampling rate. Flexible Filter Mode was developed under AURALiC's subjective auditory sense and objective testing data relationship models, to optimize the listening experience for different music and format. The “Precise” mode exhibits perfect in-band ripple and out-band attenuation performance, while the “Smooth” mode is better for overall enjoyment as it has no 'pre-ringing' effect. The other two modes, named “Dynamic” and “Balance” are optimized for different music formats as well.
