New firmware revisions for the Aurora frequently add key combinations to enable new features and options. These are documented in the Aurora firmware release notes.

However, there has been a request for a cohesive list of these combinations, so here they are:

• Press METER switch for 500ms: enables horizontal metering mode.
• Press SYNC SOURCE switch for 500ms: Turns Synchrolock On or Off.
• Press TO ANALOG OUT switch for 500ms: Toggles between 16 or 32 channel mode when used with LT-HD.
• Press TRIM while turning on STANDBY/POWER switch: Displays firmware revision in the meter display (combine rapidly flashing number from input and output row).
• Press STANDBY/POWER switch while AC power is applied: Toggles power up mode between Standby and On.
• Press SAMPLE RATE switch while applying AC power: Restore factory defaults.
