Universal Audio Apollo x4 Gen 2 Audio Interface

The onboard QUAD Core DSP allows you to record and monitor through UAD plug-ins in real-time with near-zero latency. This offloads the processing power from your computer's CPU, ensuring your system remains stable even during complex recording sessions.

The Apollo x4 Gen 2 requires a Thunderbolt 3 or 4 connection to function. If your computer uses a different port type, you will need a certified Thunderbolt adapter, though performance may vary depending on your specific hardware configuration.

Powered by Sonarworks, this feature integrates directly into the interface to calibrate your studio monitors or headphones. It helps flatten the frequency response of your listening environment, ensuring your mixes translate accurately to other playback systems.

Yes, you can expand your setup by connecting additional Thunderbolt-equipped Apollo interfaces to your system. You can also utilize the optical ADAT or S/PDIF inputs to add external preamps or digital converters to your I/O chain.

Unison technology allows the interface to physically adjust its input impedance and gain staging to match the characteristics of classic analog hardware. When you load a Unison-enabled plug-in, the preamp circuit behaves exactly like the vintage gear being emulated.

Yes, the UAD Console app includes support for immersive audio formats. This allows you to route and monitor complex multi-channel setups directly within the interface's digital mixing engine.
