Elite audio conversion with new HEXA Core processing and surround sound monitoring.

The Apollo X8 8-channel thunderbolt audio interface from Universal Audio provides studios with an unparalleled combination of elite-class conversion, HEXA Core DSP acceleration and UAD plug-ins. Perfect for professional and project studios alike, the Apollo X8 features 18x24 channel I/O to handle any setup. Four premium mic preamps, including Unison technology, deliver pristine recordings. With Thunderbolt 3 connectivity, experience high-speed, low-latency tracking and mixing.

HEXA Core Processing Provides 50 Percent More DSP Power

The Apollo X8 is powered by HEXA Core processing, providing 50-percent more DSP power than previous models. This allows you to run more UAD plug-ins in real time, unlocking creative potential. From vintage EQs and compressors to guitar amp simulations and reverb, UAD plug-ins are widely considered the best in the industry.

Premium Mic Preamps for Pristine Recordings

The Apollo X8 features four premium mic preamps, including Universal Audio's Unison technology. Unison preamps provide stunning emulations of coveted preamps like the Neve 1073, allowing you to track through an authentic preamp model with near-zero latency. The result is rich, musical recordings that capture all the nuance and detail.

Versatile I/O for Any Studio Setup

With 18 inputs and 24 outputs, the Apollo X8 handles any studio setup with ease. Connect microphones, instruments, monitors and more for recording, mixing and monitoring. Eight digitally controlled analog outputs provide flexible routing options, while two headphone outputs allow multiple artists to track simultaneously.

Thunderbolt 3 for High-Speed, Low-Latency Performance

Thunderbolt 3 connectivity provides blazing-fast data transfer speeds, enabling high channel counts, low buffer sizes and sub-2ms roundtrip latency. This level of performance allows for responsive monitoring and recording with software instruments and virtual instruments. The Apollo X8 is also compatible with Thunderbolt 2 using an adapter.
