Get Our Most Powerful Desktop Apollo Ever

With four Unison™ preamps and dual front panel Hi‑Z instrument inputs, Apollo x4 lets you track through emulations of classic gear from Neve, Manley, API, Fender, and dozens more, giving you the rich analog textures used on the greatest recordings of our time.
 
Hear the Details Like Never Before
Now in its Gen 2 design, Apollo x4 features our highest-resolution D/A converters ever. This enhanced monitoring — when paired with features like Apollo Monitor Correction by Sonarworks* — means you’ll hear the most accurate representation of your recordings when mixing through monitors or headphones.
