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, 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(TM)-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
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. 

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 worlds most recorded mic preamps.

A Full Suite of Classic Analog Processing Onboard
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 x6 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, the Unison-enabled UA 610-B Tube Preamp & EQ, and iconic guitar and bass amps from Marshall and Ampeg.
