Universal Audio Apollo x16 Heritage Edition

The flagship Apollo x16 allows music producers, project, and post-production studios to track, overdub, and mix with elite-class A/D and D/A conversion, HEXA Core UAD plug-in processing, Dual-Crystal clocking, and 7.1 surround sound monitoring — all in a sleek rackmount Thunderbolt 3 audio interface for Mac or Windows.
Built upon UA’s 60-year heritage of audio craftsmanship, this 18 x 20 interface delivers the widest dynamic range (133 dB) and lowest THD+N (-129 dB) of any integrated audio interface on the market, all-new HEXA Core processing — yielding 50% more DSP for running acclaimed UAD Powered Plug-Ins in real time — plus it includes LUNA Recording System, giving you a fully-integrated music production application.
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 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.
Apollo x16 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.
