Sound Pure's Take
The Universal Audio Apollo x16 (Gen 1) is an absolute titan for hybrid tracking facilities, mixing suites, and analog console users. Unlike its desktop and smaller rackmount siblings that focus on onboard mic preamps and Unison processing, the x16 is purpose-built as a pure line-level conversion powerhouse—packing 16 channels of pristine analog I/O via DB25 connectors into a single 1U chassis.
At the center of the x16's sound is Universal Audio's elite-tier conversion, featuring Dual-Crystal clocking and ultra-wide dynamic range (up to 133 dB on monitoring outputs). Combined with onboard HEXA Core DSP processing, it allows engineers to run massive UAD plug-in chains in real-time without straining host CPU bandwidth. With switchable +24 dBu headroom settings designed to integrate seamlessly with large-format analog desks and high-end outboard racks, the Gen 1 x16 remains one of the most capable routing central hubs on the market.
From Universal Audio
16 Channels of Elite Audio Conversion, HEXA Core Processing and Surround Sound Monitoring.
The flagship Apollo x16 allows music producers, project, and post-production studios to track, overdub, and mix with new world-beating A/D and D/A conversion, HEXA Core UAD plug-in processing, and 7.1 surround sound monitoring — all in a sleek rackmount Thunderbolt 3 audio interface for Mac or PC.
Built upon UA’s 60-year heritage of audio craftsmanship, this 18 x 20 interface boasts the widest dynamic range (133 dB) and lowest THD+N (-129 dB), of any integrated audio interface on the market. Plus, with all-new HEXA Core processing, you’ll get 50% more DSP for running acclaimed UAD Powered Plug-Ins in real time.
In addition to its elite-class audio conversion, Apollo x16 features selectable operating level for compatibility with professional +24 dBu gear, as well as an integrated monitor controller and built-in talkback mic.
- Experience elite-class A/D and D/A conversion with the widest dynamic range and lowest signal to noise of any integrated audio interface available
- Track and mix with powerful HEXA Core processing, featuring 6 UAD DSP chips for running more award-winning UAD Powered Plug-Ins in real time
- Easily connect to professional studio gear with 16 x 16 analog I/O via DB-25 connections, plus switchable +24 / +20 dBu headroom settings
- Work in surround formats up to 7.1, complete with speaker calibration and folddown
Elite-Class A/D and D/A Conversion
With thousands of chart-topping songs and hundreds of Grammy-winning albums under their belt, Apollo interfaces are no strangers to tracking stellar-sounding records. To improve on the previous generation Apollo interface’s class-leading audio conversion, UA engineers obsessively auditioned the latest A/D and D/A converters — ultimately pairing elite-class 24-bit/192 kHz converters with all-new analog circuitry for an ultra-pristine signal path.
With 133 dB dynamic range and THD+N of -129 dB, the Apollo x16’s open, natural sound quality bests every interface in its class — regardless of price — and is the perfect starting point for applying UAD processing.
Realtime UAD HEXA Core Processing
Apollo x16 features new HEXA Core processing, with six DSP chips and 50% more UAD plug-in processing power than previous Apollos. This lets you run more UAD plug-ins, whether you’re tracking in real time with channel strips from Neve, Manley, Helios, or API, or running high UAD plug-in counts when mixing in your DAW.
From the tube warmth of Pultec EQs on guitars to the musical tube limiting of the LA-2A on vocals, or the pump of a genuine 1176 or Fairchild 670 tube compressor on drums, your recordings will take a giant leap forward with a rich, three-dimensional analog sound that UAD plug-ins provide.
A Full Suite of Classic Analog Processing Onboard
Of course, a hallmark feature of Apollo is its Realtime UAD Processing, letting you run the full library of UAD plug-ins with near-zero latency. Apollo x16 includes the Realtime Analog Classics Plus plug-in bundle, so you can record and mix with the world’s only authentic Teletronix LA-2A, 1176LN, and Fairchild compressors, Pultec EQs, and many more.
Access the World of UAD Powered Plug-Ins
Going beyond the included Realtime Analog Classics Plus plug-ins, Apollo x16 lets you tap into the full UAD Powered Plug-In library of name-brand vintage EQs, compressors, reverbs, tape machines, channel strips, and more — at near-zero latency, regardless of your audio software’s buffer size and without taxing your computer’s CPU.
With exclusive emulations from SSL, Neve, Studer, Manley, API, Ampex, Lexicon, Fender, and more,* it’s like having a studio full of iconic analog gear, in a single rack space. And unlike competing interfaces, these award-winning DSP-powered plug-ins are also available in your DAW for mixing.
Surround Sound Monitoring and +24dBu Operation
With comprehensive surround monitoring support for formats up to 7.1, Apollo x16 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x16 offers selectable +24 dBu operation for out-ofthe-box compatibility with professional mixing consoles and other high-end pro audio equipment.
Build a Networked Studio System Over Thunderbolt
Apollo x16 offers 18 x 20 simultaneous inputs/outputs (16 x 18 analog I/O) and two builtin Thunderbolt 3 ports, which are backwards-compatible with Thunderbolt 1 and 2 Macs via adapter (sold separately). This allows users of any Thunderbolt-equipped Apollo Twin or Apollo rackmount audio interfaces to easily combine up to four Apollos and six total UAD-2 devices — adding fast, high-bandwidth I/O and DSP as your studio grows.
