While you do not need to use the AES16, Aurora was designed with the AES16 in mind. When interfaced with an AES16 in PC or Mac, you have individual channel control, levels and monitoring. 64 meters are available, one for each digital and analog input and output. You also have control over all front panel settings. Extensive routing is available, with any input assignable to any output. Once configured, all settings can be saved for immediate recall later – a huge benefit for live performance and broadcast applications. If you wish to record all 16 channels at 192kHz into a PC or Mac based digital audio workstation, the AES16 is the only reasonably priced solution that provides for 16-channels of digital I/O at sample rates up to 192k, so it is the ideal companion for the Aurora 16.
