The associated Sync Source LED indicators flash in the absence of a suitable clock signal, while the adjacent Synchro Lock LED reflects one of the most potent features of the Aurora. Of these, Ext/2 syncs to word clock at half the desired sample rate, for use with dual-wire AES-EBU devices - the Aurora 16 supports either 16 digital channels in single-wire mode, or eight in dual-wire mode - and LSlot is typically from the optional LT-ADAT card. A sample rate button has a periphery of LED indicators displaying the current rate, from 44.1, 48, 88.2, 96, 176.4 and 192 kHz, with six sync options.

The Aurora connects to the outside world using a bank of D-Sub connectors. Off-the-shelf cables from various third-party companies are available for direct connection to digital mixers and recorders from manufacturers such as Mackie, Sony, Tascam and Yamaha. The remaining ports are all DB25 connectors for Analogue In 1-8, Analogue Out 1-8, AES I/O 1-8, and (on the Aurora 16 only) Analogue In 9-16, Analogue Out 9-16 and AES I/O 9-16. The Aurora rear panel has a standard IEC mains connector for its internal PSU, BNC word clock in and out, MIDI In and Out (to control the Aurora mixer and update its firmware in the absence of an AES16 card), and a cover for the LSlot port that you can use to add the optional LT-ADAT expansion card, which offers two ADAT lightpipe inputs and outputs and supports high sample rates using S/MUX technology. Partnering Aurora converters with an AES16 card provides various additional features, which is why I decided to review them both together. The Aurora is available in eight-channel and 16-channel versions, and has already caused a stir in the audio community for offering such high quality at significantly lower prices than some competitors. Now they have completed the circle by offering rackmount converters of their own with similarly high quality to that of their soundcards. With this in mind, Lynx introduced their AES16, which as its name suggests supports up to 16 input and output channels of AES-EBU digital audio at sample rates up to 192kHz. However, many studios still use rackmounted converters or digital mixers, yet with the continued move to computer-based workstations, need a way to interface these to their Macs or PCs. Lynx products are now to be found in lots of professional recording and mastering studios worldwide. With their Lynx One and Two soundcards (reviewed in SOS November 2000 and March 2002 respectively), Lynx Studio Technology have done more than any other company to dispel the myth that audio converters are inevitably compromised when mounted inside a computer. With even the cheapest soundcards now offering 24-bit, 192kHz recording, is it still worth investing in high-end converters? Lynx certainly think so.
