The Universal Audio Apollo x8 is a rack-mountable Thunderbolt 3 audio interface with real-time UAD processing designed for high-resolution recording and mixing for musicians, producers, and audio engineers in mobile production rigs and studios of any size. Delivering the sound, feel, and flow of analog recording with low noise and wide dynamic range, the interface combines versatile inputs and outputs, a robust plug-in bundle, and 50% more DSP than earlier Apollos. Additionally, its switchable headroom setting facilitates proper level-matching with a variety of audio equipment. Designed to perform a central role in a modern studio, the Apollo x8 offers digital resolutions up to 24-bit/192 kHz, plus an array of analog and digital I/O. The interface features four microphone preamps with Unison integration for UAD emulations of classic analog preamps, two 1/4" Hi-Z inputs, and eight 1/4" line-level inputs. Each mic preamp boasts a switchable low-cut filter, 48V phantom power, pad, polarity inversion, and stereo linking. Digital I/O ports include 2-channel S/PDIF and 8-channel ADAT with support for S/MUX. Word clock I/O is provided on BNC jacks. The built-in HEXA Core processing utilizes six DSP chips to enable monitoring and recording audio using classic analog emulations with near-zero latency. The included Realtime Analog Classics Plus plug-in bundle empowers you with 16 plug-ins ranging from compressors and EQs to virtual guitar/bass amps and time-based processors. The included Console application provides control and recall of all interface and UAD plug-in settings including channel-strip presets, drag-and-drop functionality, and dynamically resizable windows. Core Audio and Windows drivers ensure compatibility with all major DAWs, including Pro Tools, Logic Pro, Cubase, Live, and more. The Apollo x8 offers a comprehensive monitor section with talkback functionality and dedicated front-panel controls for Alt Speakers, Dim, and Mono functions, as well as input and output metering capabilities. In addition to the dedicated stereo monitor feed and dual headphone outputs, eight 1/4" outputs are available for connection to power amps, active monitors, or an analog mixer. A total of four Apollos and six total UAD devices can be combined, allowing Thunderbolt users the ability to expand their I/O and DSP. The two Thunderbolt 3 ports are backward-compatible with Thunderbolt 1 and 2 via a qualified adapter (available separately).
