AURALiC ALTAIR: High-Quality Streaming DAC 發表
AURALiC在AXPONA展覽上發表了全新的ALTAIR High-Quality Streaming DAC，若是熟悉AURALiC的朋友，可以將其想成VEGA DAC與AREIES Streamers的一體機。ALTAIR擁有多達15個輸入，幾乎無所不包了。
(Streaming Inputs: Network Shared Folder [on both NAS and computer], USB drive, Internal music storage (optional), uPnP/DLNA media server, TIDAL and Qobuz streaming, Internet Radio, AirPlay, Bluetooth, Songcast and RoonReady; Digital Inputs: AES/EBU, Coaxial, Toslink, USB device to computer, 2 USB host for storage and external DAC, RJ45 Gigabit Ethernet and 802.11b/g/n/ac Tri-Band WiFi.)

AURALiC總裁Xuanqian Wang先生表示經過三年多的研發，AURALiC的Lightning streaming platform串流平臺已經非常成熟與穩定，ALTAIR是產品線的延伸，並非取代VEGA或是ARIES，並且ALTAIR擁有最高的聲音水準。Lightning DS支援TIDAL, Qobuz, Internet Radio，ALTAIR也能使用AirPlay, Songcast與Bluetooth，還有最新的Roon。

• AURALiC Tesla Platform 獨家Tesla解碼處理中心
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 and MQA support. All these features can be delivered through automatic online updates without user’s attention.
• Femto Master Clock 雙飛秒時鐘
The dual-frequency Femto Master Clock inside the ALTAIR is specially designed and optimized for its ESS Sabre 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 ALTAIR to be able to lock on with highest clock precision (equal to 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 a 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, ALTAIR can bring you vivid music with natural detail and solid sound image.
• Linear Power Supply 線性電源
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 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 to AURALiC’s specifications, and unique wiring to ensure zero vibration and very low noise to avoid impacting the sensitive audio electrical circuit.
Comparing 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 多種數位濾波
ALTAIR has four built-in filter modes which allows its user to customize sound best befitting their personal preference. Those filter modes were developed from AURALiC’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.
