Operational Overview Audio Interface First and foremost, Apollo x6 Gen 2 is a premium 16 x 22 Thunderbolt 3 audio interface with elite-class 24-bit/192 kHz audio conversion. Apollo connects to the outputs and inputs of other audio gear, and performs analog-to-digital (A/D) and digital-to-analog (D/A) audio conversions on the gear’s signals.
Apollo’s connection to the host system is lost (if the Thunderbolt 3 cable is unplugged), the current UAD-2 plug-in configurations remain active for processing until Apollo is powered down. Note: Standalone use is unavailable when cascading multiple Apollo units. Apollo x6 Gen 2 Hardware Manual Introduction...
The features and functionality of all individual UAD-2 Powered Plug-Ins is detailed in the UAD Plug-Ins Manual. Refer to that document to learn about the operation, controls, and user interface of each UAD-2 plug-in that is developed by Universal Audio.

When the unit is powered on, the Universal Audio logo (#1) is illuminated. The external power supply must be properly connected for this switch to function.
Apollo x6 rear panel (digital portion) (28) Power Input The included external power supply connects to this 4-pin locking XLR jack. Apollo x6 requires 12 volts DC power and draws a maximum of 72 watts (30 watts typical). To eliminate risk of circuit damage, connect only the factory-supplied power supply. Use the Power switch on the front panel to power the unit on and off.
3 – 4 Note: The ADAT ports use TOSLINK JIS F05 optical connectors. Some devices use this type of connector for optical S/PDIF connections. However, Apollo x6’s ADAT ports do not support the S/PDIF protocol (use the coaxial S/PDIF ports instead).
