Product Description

The new Aurora line of digital audio converters from Lynx Studio Technology offers unprecedented audio quality and control in single-rack space eight and sixteen channel models. The Aurora 16 features 192 kHz analog to digital and digital to analog conversion with front panel control of all routing and sample rate options. Extended functions in Aurora are accessible via computer with the Lynx AES16 or by infrared using compatible laptops and handheld Pocket PCs. The rear panel has Clock and MIDI In and Out connectors and an LSlot bay, for the optional use of ADAT, Firewire and other audio interfaces.

Aurora 16 is a 16-channel 24-bit/192 kHz analog-to-digital/digital-to-analog converter in a single-space rack-mount case. Representing Lynx Studio Technology's first rack-mount product, Aurora was developed using the next generation of Lynx acclaimed conversion technology and rock-solid digital interface circuitry.

Aurora provides professional I/O interfacing for ease of installation in most studios and live sound applications. The analog I/O is electronically balanced and supports both +4dBU and 10dBV nominal levels. The AES digital I/O is transformer coupled and is capable of driving 500 feet of cable at 192kHz. Both dual and single-wire AES channel modes are supported.

Aurora's ergonomically designed front panel provides easy access to important controls and signal status. Unique to this product class, Aurora also offers extensive remote control capability. All front panel features as well as other low-level options can be controlled from the Lynx AES16 digital interface card on Windows and Macintosh platforms; a Pocket PC or laptop via infrared; MIDI; or an LSlot interface card. Multiple remote set-up configurations can be stored and recalled.

The on-board 32-channel digital mixer provides extensive routing and mixing options. Acting as a powerful patch bay-style digital router, Aurora can easily route signals between analog and digital inputs on a channel-by-channel basis. Mixing capability on each output also provides flexible zero-latency monitoring.

The LSlot expansion port accepts cards that provide compatibility with current and emerging digital interface standards, including Firewire, ADAT, and others. In addition to soon-to-be released LSlot cards, the LSlot port is compatible with existing Lynx LStream cards including the LS-ADAT and LS-AES.

Lynx's proprietary SynchroLock jitter reduction technology, from the AES16, is also included. This exclusive feature provides extreme jitter reduction of up to 3000:1, allowing Aurora to output an extremely clean clock output for driving the digital audio system.

All analog and digital connections use DB25 connectors with industry standard pin-outs which are compatible with off-the-shelf cables from manufacturers such as Mogami, ProCo, Hosa and others.
