With four Unison™ preamps and dual front panel Hi‑Z instrument inputs, Apollo x4 lets you track in realtime through preamp and channel strip plug-ins from Neve, Manley, API, and dozens more, giving you the same rich analog textures used on the greatest recordings of our time.

Right out of the box, Apollo x4 gives you the plug-ins used by the world’s best engineers. Along with included Teletronix LA-2A and 1176 compressors, UA 610, Century, and LA-6176 tube channel strips, plus UAD guitar amps like Showtime ’64 and Lion ’68 — you can tap into the entire UAD library of over 200 titles to unlock proven hit-making sounds.

Now in its Gen 2 design, Apollo x4 features UA’s highest-resolution D/A converters ever paired with Apollo Monitor Correction powered by Sonarworks.® This means that when you playback your audio through monitors or headphones, you’ll not only hear the most pristine representation of your recordings, there will be no surprises when you listen to your final mix or master.  

Find Your Flow in the UAD Console App 

Just like an analog studio, where a console is the heart of the workflow, Apollo x4 has a powerful digital mixing engine where you control plug-in routing and monitoring. And with the latest features like Auto-Gain, Bass Management and Plug-In Scenes, it’s easy to find a flow that fits your needs.
