The Apollo 16 is Universal Audio's flagship 24-bit/192 kHz audio interface, delivering world-class conversion with 16 x 16 analog I/O - twice the analog I/O of the original Apollo.

World-Class 24-bit/192 kHz Conversion
Apollo 16 brings a true "no compromise" approach to every aspect of its audio signal path. Building upon decades of UA hardware expertise, it features meticulous analog circuit design, top-end converters, and DC-coupled outputs - providing the lowest THD and highest dynamic range of any converter in its class. Specifically, the Apollo 16's deep, wide soundstage, and its exceptionally open and transparent sound, makes it the ideal centerpiece for professional recording studios.

Realtime UAD Plug-In Processing for Tracking, Mixing, and Mastering
With its standard UAD-2 QUAD processing onboard, Apollo 16 allows recording in real time through UAD Powered Plug-Ins - with as low as sub-2ms latency - so you can monitor, audition, and "print" audio through stunning analog emulations from Ampex, Lexicon, Manley, Neve, Roland, SSL, Studer, and more.** Better still, Apollo 16's Realtime UAD Processing is also available during mixing and mastering, so that music producers can employ UAD plug-ins (VST, RTAS, AU, AAX 64) throughout the creative process.

High-speed Thunderbolt Connection to your Mac
Apollo 16 offers compatibility with Thunderbolt technology on Macs via a user-installable dual-port Thunderbolt Option Card (sold separately). Thunderbolt provides greater UAD plug-in instances, improved performance at high sample rates, and reduced UAD plug-in latency. Because Thunderbolt offers many times the bandwidth of FireWire, it allows studios to connect numerous devices in series with the Apollo interface - including hard drives, processors, and additional computer monitors - all with fast, flawless performance.

Hardware Design and Workflow
Apollo 16 boasts straightforward 16 x 16 analog I/O via convenient DB-25 connections - perfect for pairing with mixing consoles, outboard processors, cue/headphone systems, and more. Two Apollo 16 units can be cascaded over MADI for an expanded system with eight UAD processors and 32 x 32 simultaneous analog I/O, capable of handling large professional mixes. The Apollo 16's enhanced routing capabilities includes four stereo Cue mixes with individually assignable outputs, and a "Virtual I/O" feature that allows Realtime UAD Processing of DAW tracks and virtual instruments.
Apollo 16 boasts numerous design details that give you a fast, natural workflow. Its Monitor outputs are digitally controlled analog, so you don't lose audio resolution when you adjust gain. More than 195 high-visibility LEDs provide full input and output metering, and with zero "hot spots" or light bleed. Finally, standalone operation means that you can use Apollo's audio connections, and last-used DSP mixer settings, even without a computer connected.

Console Application and Console Recall Plug-In
The Console application is Apollo's software control interface. Its intuitive, analog console-style design provides "realtime" tracking and monitoring with UAD Powered Plug-Ins - a feature not found in any other interface. Complete Apollo Console setups can be saved as presets, or even saved within your sessions using the Console Recall plug-in (VST, AU, RTAS, AAX 64). This enables hardware recall of all Apollo settings, even months and years after you last opened your session.

Deeper Integration with Pro Tools, Logic, Cubase and More
Apollo 16's Core Audio and ASIO drivers ensure compatibility with all major DAWs, including Pro Tools, Logic Pro, Cubase, and more. The included Console application and companion Console Recall plug-in (VST, AU, RTAS, AAX 64) provide control and recall of all interface and Realtime UAD plug-in settings within your DAW sessions, even months and years later. A new "PT Mode" ensures that Pro Tools can take advantage of all 16 analog inputs/outputs for hardware inserts - and maximizes analog I/O in a multi-unit setup.
