Comprehensive Plug-in Ecosystem:
The built-in QUAD Core DSP processor lets you use a vast library of UAD plug-ins (sold separately) in real time, including emulations of Teletronix LA-2A compressors, Pultec EQs, and reverbs from legendary studios Capitol Chambers and Ocean Way.

Precision Monitoring:
Apollo Monitor Correction, combined with Sonarworks technology built into UAD software (available for a fee in November 2024), ensures precise monitoring across all your speakers or headphones. So you can work with confidence, knowing your mix will translate faithfully to any playback system.

Intuitive Interface:
The UAD Console app provides intuitive control of your Apollo system, with advanced features like Auto Gain, Bass Manager, and Plug-in Scenes.

Unlimited Expandability:
By daisy-chaining up to four Apollo interfaces, you can create a modular, scalable recording system that meets your most demanding needs.
