Overview
The hardware is identical to the UAD Analog Classics Pro version: elite-class 24-bit / 192 kHz Apollo X Gen 2 conversion, two Unison-enabled mic preamps, DUO Core DSP for realtime UAD plug-in processing, and the latest UAD Console with Auto-Gain, Plug-In Scenes, Bass Management, and immersive audio support. Where UAD Analog Classics Pro pulls ahead is the software — adding sought-after plug-ins like the Avalon VT-737sp, Empirical Labs Distressor, dbx 160, Manley Reference Microphone Preamp, Lexicon 224 Reverb, Moog Minimoog, Waterfall B3 Organ, and the complete Pultec EQ collection.

UAD Analog Classics Pro Plug-In Bundle
This Apollo ships with Universal Audio's UAD Analog Classics Pro plug-in bundle — 80+ UAD titles covering channel strips, compressors, EQs, tape emulation, reverbs, and analog instruments. The bundle is delivered digitally through your UA Connect account after registration. For the full current list of included plug-ins, see Universal Audio's product page.
Which Bundle Should You Choose?
Universal Audio offers Apollo hardware paired with different UAD plug-in bundles: UAD Analog Classics (30+ plug-ins), UAD Analog Classics Pro (80+ plug-ins), and — on the flagship x16 and x16D — UAD Complete (200+ plug-ins). The hardware is identical between bundles; the difference is the size of the plug-in library you receive. If you already own a deep UAD plug-in library, the lower-tier bundle may make more sense. If you're building your first Apollo studio, the larger bundle is typically the better value per plug-in.
What's in the Box
- Apollo Twin X DUO Gen 2 audio interface

- Thunderbolt 3 cable (USB-C)
- UAD Analog Classics Pro UAD plug-in bundle (digital via UA Connect)
