Page 9: Operational Overview
Operational Overview Audio Interface First and foremost, Apollo x4 Gen 2 is a premium 12 x 18 Thunderbolt 3 audio interface with elite-class 24-bit/192 kHz audio conversion. Apollo x4 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. -
Page 10: Standalone Use
UAD Powered Plug-Ins in a DAW Apollo x4 and UAD plug-ins can also be used with a DAW without the use of UAD Console. UAD plug-ins loaded within the DAW operate like other (non-UAD) plug-ins, except the processing occurs on the Apollo x4 DSP instead of the host computer’s processor. In this scenario, UAD plug-ins are subject to the latencies incurred by I/O buffering. -

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.
