Furnished with Universal Audio's flagship 24-bit / 192 kHz conversion, the Apollo x16 gives engineers in commercial recording studios, concert tours, and postproduction facilities the confidence of recording and mixing with detailed imaging, unbelievably low distortion (-129 dB), and unmatched dynamic range (133 dB). Additionally, its switchable headroom setting facilitates proper level-matching with large-format consoles and a variety of boutique and pro-level audio equipment. The interface features 16 balanced analog line-level inputs and outputs on DB25 connectors, perfect for patching in external mic preamps and custom signal chains or hooking up to a bunch of channels on a classic analog mixing board. You also get a pair of XLR monitor outputs and stereo AES/EBU I/O, which can be utilized when you need to connect a dedicated feed to a mastering system or if you wish to incorporate alternative stereo converters. Utilize the BNC wordclock input and output jacks to accurately clock to house sync or lock other digital equipment to the Apollo x16. 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 x16 offers a comprehensive monitor section with talkback functionality and dedicated front-panel controls as well as full input and output metering capabilities. In addition to the dedicated stereo XLR monitor output, the 16 line outputs can feed alternate monitors and outboard processors. In fact, the Apollo x16 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 x16 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 x16. 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 x16 interface found in the standard edition but with more plug-ins. The standard Apollo x16 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 UA's flagship 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, and with no burden on your computer's CPU Two high-speed
