Awesome interface for the digital producer

By James H.

Awesome I/O... I paired my x8 with an PCIe OCTO and can load up all the plugins I need.

With the Apollo x8 Thunderbolt 3 Audio Interface, experience elite audio conversion technology that sets a new standard in professional audio production. This advanced interface is equipped with Real-Time UAD Processing, four Unison Mic Preamps, and powerful HEXA Core Processing, making it an indispensable tool for music producers, project studios, and post-production environments on both Mac and PC platforms.

Built on Universal Audio's 60-year legacy of audio excellence, the Apollo x8 offers an 18 x 24 interface configuration, featuring four Unison-enabled mic preamps. These preamps deliver authentic emulations of legendary preamps from industry giants like Neve, API, Manley, and SSL, ensuring your recordings capture the true essence of these classic sounds. The cutting-edge HEXA Core processing provides a 50% increase in DSP power, enabling seamless real-time operation of UAD Powered Plug-Ins.

The Apollo x8 boasts elite-class A/D and D/A conversion, providing near-zero latency tracking through Unison preamp emulations. This results in an open, natural sound quality that rivals any high-end converter available, regardless of price. With a remarkable 129 dB dynamic range and -119 dB THD+N, the Apollo x8 ensures an ultra-pristine signal path, making it the ideal platform for applying UAD processing.

The interface's new HEXA Core processing, featuring six DSP chips, allows for more UAD plug-in processing power than ever before. This means you can run more UAD plug-ins in real time, whether you're tracking with channel strips from Neve, Manley, or API, or handling high UAD plug-in counts during mixing sessions in your DAW. Unison Technology, exclusive to Universal Audio, enables the Apollo x8 to deliver the genuine sound of Neve, API, and Manley Preamps by integrating its mic preamps with onboard HEXA Core DSP Acceleration. This technology physically reconfigures the Apollo interface's impedance to replicate the classic sounds of the world's most recorded mic preamps.

Included with the Apollo x8 is the Realtime Analog Classics Plus plug-in bundle, allowing you to record and mix with iconic compressors, preamps, and amps from renowned brands like Teletronix, Marshall, and Ampeg. With access to the comprehensive UAD Powered Plug-In library, you can utilize legendary vintage EQs, compressors, reverbs, tape machines, channel strips, and more, all at near-zero latency.

The Apollo x8 supports surround monitoring for formats up to 7.1, making it an excellent choice for engineers and producers working on audio and music for video games, television, and web content. It also offers selectable +24 dBu operation for seamless compatibility with professional mixing consoles and other high-end pro audio equipment. With 18 x 24 simultaneous inputs/outputs (8 x 8 analog I/O) and two built-in Thunderbolt 3 ports, the Apollo x8 can easily integrate with any Thunderbolt-equipped Apollo Twin or Apollo rackmount audio interfaces. This allows for the addition of fast, high-bandwidth I/O and DSP as your studio grows, making the Apollo x8 a scalable and future-proof solution for your evolving audio needs.
