Furnished with elite-class 24-bit / 192 kHz conversion rivaling dedicated high-end converters, the Apollo x8p gives music creators, record producers, and postproduction engineers the appreciable value of crystal-clear, high-resolution recording and mixing with ultralow distortion (-119 dB) and immense dynamic range (129 dB). Additionally, its switchable headroom setting facilitates proper level-matching with a variety of audio equipment. The interface features eight XLR-1/4" mic/line inputs and two 1/4" Hi-Z inputs, all with Unison integration for precise UAD emulations of classic analog preamps—impart vintage character of your choosing on microphone and instrument recordings while bypassing the unpredictable nature of old equipment. Plus, the 8-channel DB25 connector on the rear panel can be used to patch in line-level signal from virtually any outboard mic preamp, or direct output from a console. Thanks to the switchable low-cut filter, pad, polarity inversion, 48V phantom power, and stereo linking on each preamp, you can efficiently optimize your incoming signals with straightforward buttons on the Apollo x8p's face. In addition to the eight primary analog inputs, you can record up to eight more channels by connecting ADAT-equipped external preamps to the Apollo x8p's TOSLINK optical input ports (SMUX is supported for sample rates over 48 kHz). ADAT optical outputs are also featured on the Apollo x8p, allowing it to route up to eight channels from your DAW to a digital mixer, headphone distribution system, or external D/A converter. Utilize the BNC wordclock input and output jacks to accurately sync clock to the house, or lock other digital equipment to the Apollo. The built-in HEXA Core processing utilizes six DSP chips, granting 50% more DSP than earlier Apollos and the ability to monitor and record audio using classic analog emulations with near-zero latency and no burden on your computer's CPU. The plug-in bundle included with the Heritage Edition empowers you with 34 top-notch plug-ins ranging from vintage compressor and EQ collections to virtual guitar/bass amps, time-based processors, and tape emulation. 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. Mac and Windows drivers ensure compatibility with all major DAWs including Pro Tools, Logic Pro, Cubase, Ableton Live, and more. The interface also integrates seamlessly with LUNA, Universal Audio's free Mac-based, single-window recording system with unlimited track counts and full Audio Units support. The Apollo x8p 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 two front-panel headphone outputs (great for handling multiple cue mixes), eight line outputs are available on a DB25 connector for hooking up a second set of monitors and outboard processors. In fact, the Apollo x8p is capable of acting as a 7.1 surround-sound monitor controller. At any point, you can increase the power and capability of the Apollo x8p through integration of qualified Universal Audio hardware. Up to four Apollo interfaces and six total UAD-2 devices can be combined, allowing Thunderbolt users the ability to expand their I/O and DSP without abandoning the Apollo x8p. The two Thunderbolt 3 ports are backward compatible with Thunderbolt 1 and 2 via a qualified adapter (available separately). Heritage Edition The Heritage Edition features the same Apollo x8p interface found in the standard edition, but with more plug-ins. The standard Apollo x8p includes the Realtime Analog Classics Plus bundle (16 plug-ins), and the Heritage Edition adds 18 more plug-ins for a total of 34 revered UA-powered plug-ins. The Power of Apollo X Track, overdub, and mix with elite-class AD/DA conversion and DSP-powered plug-ins Dual-crystal clocking features dedicated crystals for 44.1 / 88.2 / 176.4 kHz and 48 / 96 / 192 kHz sample rates, resulting in stunningly low jitter (under 10 picoseconds) for pure, artifact-free recordings and solid stereo imaging HEXA Core UAD processing for tracking through models of vintage compressors, EQs, tape machines, mic preamps, and guitar amps with near-zero latency and 50% more DSP than earlier Apollos, all with no burden on your computer's CPU Unison technology nails the tone of sought-after tube and solid-state mic pres including their input impedance, gain-stage sweet spots, and the component-level circuit behaviors of the original hardware Two high-speed Thunderbolt 3
