Eight coil-latch relays remain entirely passive when not in use, drawing no power and producing exactly zero EMI noise. Once set, the ALTAIR G2.1’s volume control system remains electronically invisible — one more detail that helps the ALTAIR G2.1 push the boundaries of sonic performance.

Turn Your Wi-Fi into a Music Streaming Ecosystem.
We developed Lightning OS to be the highest-quality streaming environment you’ve ever heard. A meticulously-crafted software architecture designed specifically to work hand-in-hand with the powerful Tesla hardware platform found in AURALiC streaming products, Lightning OS is full of cutting-edge innovations that bring your music to life like never before. Connect to all your of high-resolution sources, take control with user apps like Lightning DS or Roon, and meet true audiophile streaming.
Display Brilliance
A 4.0-inch true color in-plane switching display with a resolution of over 300ppi provides complete operational feedback: playback status, configuration settings, and a full library view for browsing your collection.

Flexibility to Explore

The ALTAIR G2.1 offers nearly universal connectivity for access to all your digital sources. Most advanced Wi-Fi and Ethernet open your system to UPnP/DLNA media servers, shared network folders, high-resolution Internet Services, and Internet Radio, as well as RoonReady, Bluetooth, AirPlay, and SongCast control.

CD Playback and Ripping
Still have some love for your old CDs? Not to worry; you can plug a generic USB CD drive into your ALTAIR G1 then choose to play a CD, rip a CD while playing, or just rip.

As with AURALiC’s Lightning file streaming, our unique CD playback feature uses the same advanced, jitter-reducing Memory Playback technology. CD data is first read, and compared several times for accuracy into the system cache before playing. The result is elimination of potentially induced jitter from the transport, canceling any negative effects from the quality of your chosen CD drive, potentially improving performance beyond what’s offered from competitors’ CD players.

Dual 72fs Femto Clock
With a dedicated, low-noise 3uV power supply to minimize phase noise and keep it as quiet as it is accurate, our 72 Femto Master Clock is amazingly precise for less jitter, and immaculate sound. Its 72 femtosecond cycles — that’s 72 quadrillionths of a second — set a new standard for signal timing. Temperature-regulated for consistent performance, this clock is always there to keep things rock-steady.

1GB Memory Cache
Open network connections and data fetching are prone to noise that can hurt the quality of your audio signal. The Tesla G2 hardware platform dedicates a whopping 1GB of RAM to the task of caching, lowering the frequency of open circuits and helping your music sound better.

Flexible Filter Mode
Flexible Filter Mode gives you a nuanced level of control over your audio output. Its various modes were developed using a combination of objective data models and subjective testing, with each mode offering a unique array of filters to match the sonic quality of the source. Whether it’s modes to tweak in-band ripple, out-band attenuation, ultrasonic filtering and more, you’ve always got the power to dial in the performance you want.

ORFEO Class-A Module
Inspired by classic analog circuit designs, ORFEO is capable of driving an array of loads to match the characteristics of a variety of amplifiers. Using small signal components with excellent linear qualities, thermally balanced and biased into Class-A, ORFEO has the power to drive loads as low as 600 ohms while keeping noise low — open loop distortion comes in at less than 0.001%.

Smart-IR Control
Smart-IR Remote Control lets your AURALiC device map its functionality onto any remote you’d like. Just let the device know which remote you prefer, and all of its operations (play/pause, volume control, track select, etc.) can be assigned to buttons just the way you like them.

Dual Purer-Power
The Purer-Power linear power supply reduces DC current noise by as much as 90dB with its power purification module. Using a specially designed transformer and unique wiring that minimizes vibration, noise from Purer-Power is kept below 1uV across the audible spectrum, leaving you to discover the details in your music, down to the last bit.
