2 Operational Overview
2.1 Front Panel Controls and Indicators
The Aurora allows extensive parameter selection and configuration from convenient front panel
controls. For standalone use, or in situations where computer control is not possible, it is important to
be thoroughly familiar with the front panel controls and display. If the correct parameters are not
selected, it is possible to damage connected equipment.

q SAMPLE RATE
This button selects sample rate when the Aurora is set to Internal for SYNC SOURCE. Standard
rates from 44.1 kHz to 192 kHz are available. When the Aurora is slaving to an external clock source,
the LED for the measured sample rate will illuminate. Holding the SAMPLE RATE button while
connecting AC power to the Aurora will restore all settings to the factory default state. PLEASE
NOTE: After the defaults are restored, the unit must be put into standby mode to save the settings
before power is removed.
w SYNC SOURCE
This button selects the clock source that drives the Aurora sample clock generator from the following
options:
INT
Clock derived from the on-board crystal oscillator.
EXT Clock signal from WORD CLOCK input.
EXT/2 Clock signal from WORD CLOCK input running at half the desired sample rate.
Typically used with dual-wire AES/EBU devices.
AES A Clock signal from the AES I/O Port A Digital Input. Clock is derived from the first valid
AES/EBU channel.
Aurora 8
Clock signal from the AES inputs 1-4
AES B Clock signal from the AES I/O Port B Digital Input. Clock is derived from the first valid
AES/EBU channel.
Aurora 8
Clock signal from the AES inputs 5-8
LSLOT Clock signal from an LSlot/LStream card installed into the LSLOT expansion port (i.e.
ADAT, Firewire, etc.).
If no clock signal is available for the SYNC SOURCE selected, the LED for the selected source will
flash.
e SynchroLock
This LED shows the status of the SynchroLock clocking system.
Flashing
Working (analyzing incoming clock signal). It typically takes one to two minutes to
achieve final lock. The Aurora can be used prior to a locked state, but the jitter reduction
is significantly enhanced when lock is achieved.
Solid Locked. Ready to use.
