Apollo x6 Heritage Edition Rackmount 16x22 Thunderbolt 3 Audio Interface with Real-Time UAD Processing

Born from the ever-popular Apollo line of interfaces used on loads of Grammy-winning albums and chart-topping songs, the Universal Audio Apollo x6 Heritage Edition rackmount 16x22 Thunderbolt 3 audio interface combines the sound, feel, and flow of analog studio recording with upgraded clocking, surround monitoring, a robust bundle of 34 stellar UAD plug-ins, and 50% more DSP than earlier Apollos, thanks to its supercharged HEXA Core real-time UAD processing.

Furnished with elite-class 24-bit / 192 kHz conversion, rivaling dedicated high-end converters, the Apollo x6 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 two XLR mic 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 six 1/4" line-level inputs on the rear panel can be used to patch in virtually any outboard mic preamps or direct outputs 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 x6's face. In addition to the six primary analog inputs, you can record up to 10 more channels by connecting ADAT- and S/PDIF-equipped external preamps to the TOSLINK optical and S/PDIF coaxial input ports on the Apollo x6.

ADAT optical and S/PDIF coaxial outputs are also featured on the Apollo x6, allowing it to route up to 10 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 clock sync to 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 x6 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), six 1/4" line outputs are available for connection to a second set of monitors and outboard processors. In fact, the Apollo x6 is capable of acting as a 5.1 surround sound monitor controller.

At any point, you can increase the power and capability of the Apollo x6 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 x6. 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 x6 interface found in the standard edition, but with more plug-ins. The standard Apollo x6 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.
