Apollo x6 allows music producers 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, Dual-Crystal clocking, and 5.1 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 16 x 22 interface easily outperforms everything in its class with two Unison™-enabled mic preamps, providing authentic emulations of preamps from Neve, API, Manley, SSL, and more, plus all-new HEXA Core processing — yielding 50% more DSP for running UAD Powered Plug-Ins in real time.
Elite-Class A/D and D/A Conversion
With thousands of hit 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 interfaces’ 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. The Apollo X series also introduces new Dual-Crystal clocking — featuring dedicated crystals for 44.1/88.2/176.4k and 48/96/192k sample rates — resulting in stunningly low jitter, measured at less than 10 picoseconds. This translates into pure, artifact-free recordings and solid stereo imaging you can trust. With 129 dB dynamic range and -119 dB THD+N, Apollo x6’s open, natural sound rivals any dedicated high-end converter on the market — regardless of price — and is the perfect starting point for applying UAD processing.
Realtime UAD HEXA Core Processing
Apollo x6 features 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, 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.
Unison Technology: The Genuine Sound of Neve, API & Manley Preamps
Perfect for electronic musicians and post production professionals who don’t require tons of mic inputs, Apollo x6 features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, API, Manley, Helios, SSL, and Universal Audio. A Universal Audio exclusive, Unison technology nails the tone of these 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. The secret to Unison is its hardware-software integration between Apollo’s mic preamps and its onboard HEXA Core DSP Acceleration. Simply place a Unison preamp plug-in on your mic input in Apollo Console software, and it physically reconfigures the Apollo interface’s impedance — so you can tap into the classic sounds of the world’s most recorded mic preamps.
Track and mix with powerful HEXA Core processing
There are times when your computer doesn’t have enough power and speed to run all the plug-ins your recording session requires. That’s where UA’s powerful 6-core HEXA Core processor comes in. This processor yields 50% more power than the previous generation. This means that you can track in real-time with Neve, Manley, or API channel strips, or run large UAD plug-in counts while mixing in your DAW. The engineers here at Sweetwater appreciate being able to inject guitars with the tube warmth of a Pultec EQ, add the musical limiting of an LA-2A to a vocal, and pump up drums with an 1176 or Fairchild 670 — all in real-time. It’s the closest thing to having the real hardware.
Elite-class AD/DA conversion offers ultra-pristine sound
Apollos have always sounded great, but the Apollo x6’s AD/DA conversion takes it to the next level. When they were designing the latest generation of Apollos, UA engineers auditioned the latest leading-edge AD/DA technology, ultimately pairing elite-class 24-bit/192kHz converters with overhauled analog circuitry. The result is an ultra-pristine signal path with 129dB dynamic range and -128dB THD+N. Dive in, and you’ll hear for it yourself — the Apollo x6’s AD/DA rivals any high-end standalone converter on the market
A bevy of pro-level features
You can find Apollos in professional studios worldwide. That said, users have been clamoring for certain pro-level features. Good news — Universal Audio has been listening! So what’s new? First of all, the Apollo x6 includes 5.1 surround monitoring support, complete with speaker calibration and fold-down. This is great news for engineers working on audio and music for video games, film, television, and the web. Beyond that, the Apollo x6 was tailor-made for your analog console and other high-end gear, courtesy of its selectable +24dBu operation. Thanks to these and other great features, the Apollo x6 makes a great centerpiece for any studio.
Capture the sound of legendary preamps with Unison technology
The Apollo x6’s Unison preamp technology goes so far beyond traditional software modeling and emulations that it’s really in a category all its own. In essence, Unison is a bidirectional communication between the Apollo x6’s mic preamp and a Unison-capable plug-in, such as the included 610-B plug-in that re-creates the sound of UA’s classic LA-610 preamp.
The plug-in actually adjusts the preamp circuit itself, including parameters such as impedance, analog gain structure, and much more. When you adjust the Apollo x6’s preamp gain knob and physical controls, the plug-in adjusts the preamp’s behavior to match the target preamp. So you’re not simply filtering your audio to approximate the character of a famous preamp — your microphone is now interacting with the Apollo x6’s input the same way it would behave with the “modeled” preamplifier.
UAD plug-ins astounded the recording world with their incredible ability to sound like analog processors, eliminating the need for large racks of gear in the studio. Unison preamp technology will do the same thing for your mic inputs, eliminating the need to collect and maintain expensive hardware preamps just for sonic variety.
