Clock Setup - Lynx Studio Technology Aurora(N) User Manual

Clock Setup

6.2.1
(n)
The Clock Setup page is where the Aurora can be set up as a clock master, or slave to some other device in
on "Internal", unless using a Dante system, in which case
(n)
your system. The default state is with the Aurora
the default SYNC SOURCE is "Dante". In most cases, having the Aurora on "Internal" is the desirable
(n)
state, so that it can follow the sample rate of audio projects automatically, and also the system can take
advantage of Aurora's Mastering Quality clock generation. When set to "Internal", generally the Sample Rate
will be determined by the computer, either within an audio recording program, or as a global setting in the
(n)
operating system. When audio is streaming to the Aurora from the computer, the sync source and sample
rate cannot be changed from the Clock Setup page, so the Clock Setup indicator will go dim. When streaming
has stopped, then you can change sample rate to any of the supported rates between 44.1k, and 192k. This is
especially pertinent to recording to the SD card.
The "Word clock" option will only be illuminated and selectable when the Aurora
(n)
detects a valid clock
signal is being delivered to its WORD CLOCK input. When clocked via "Word clock", the Aurora
(n)
will
follow whatever sample rate is being generated by the clock master. It is critical that the clock master is
generating the sample rate that matches the rate of your audio project, to prevent recording audio at the wrong
pitch and speed.
AES In 1 and AES In 9 will only be displayed when the LM-DIG board is installed in the Module 4 position.
(n)
When clocked via AES Input, the Aurora will follow whatever sample rate is being generated by the AES
device feeding the selected input. It is critical that the clock master is generating the sample rate that matches
the rate of your audio project, to prevent recording audio at the wrong pitch and speed.
