Apollo x8p Hardware Manual Introduction 5
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 129 dB dynamic range and -118 dB THD+N, Apollo x8p’s open, natural sound 
quality 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 x8p 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, 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 musicians, engineers, producers, and sound designers, Apollo x8p features 
eight Unison-enabled mic preamps, letting you track through exacting mic preamp 
emulations from Neve, API, Manley, SSL, Helios, 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 Realtime UAD processing. 
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 x8p 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 guitar and bass amps from Marshall and Ampeg.
