Welcome
Thank you for choosing AURALiC product. POLARIS is designed for music lovers seeking for the highest levels of performance from a single compact box. It is a wireless
streamer, a music server, a DAC, a pre-amplifier with phono stage and a power amplifier
– the ultimate solution for your HiFi system.
!
High-End Wireless Streaming
POLARIS utilizes AURALiC’s award-winning Lightning Streaming Platform.
Launched in 2014, Lightning Streaming is industry’s first streaming solution that
supports Quad-Rate DSD, PCM up to 32Bit/384K through Wi-Fi network. Lightning
St r ea m ing off e rs sev era l i n nov ati v e a nd u ni q ue fea t ur e s s uch as
Gapless Playback, On-Device Playlist, Memory Cache and Bit-Perfect MultiRoom functions. This on-going platform is maintained, and continually developed
by AURALiC’s in-house software R&D team to ensure customers are regularly updated with new features through the product’s automatic software update system.
!
17 Input Sources, More to Come
POLARIS can act as home music center for virtually all input source. It read music
stored on USB drive, internal hard disk, network shared folder and DLNA/UPnP music server. By joint use with Lightning DS, you can also stream TIDAL, Qobuz and
listen to Internet Radio at any time. POLARIS’s AirPlay, Songcast and Bluetooth inputs provide alternative way to stream your favorite music from Apple
Music, Spotify and other service providers through smartphone or computer.
!
Hybrid Volume Control
AURALiC is introducing another innovative technology: Hybrid Volume Control for
POLARIS. The Hybrid Volume Control uses both analog and digital volume control
together for optimum audio performance and the best possible sound quality. The
analog attenuators reduce the signal level in 12dB steps whilst the DAC's internal
digital volume control handles small amounts of volume change within each step. By
using this technology, the DAC chip always operates in the best performance range,
bringing much lower distortion, better dynamic range and high sound quality at low
volume levels.
!
Femto Master Clock
The dual-frequency Femto Master Clock inside the POLARIS is specially designed
and optimized for its ESS Sabre DAC chip: with one frequency for 44.1K and multiple of 44.1K, and with another working frequency for 48K. This design makes POLARIS to lock on with highest clock precision (equal to the VEGA’s “EXACT” mode)
at all time without dropouts.
