Apollo 8 Hardware Manual Introduction 5
Four Mic Preamps with Unison™ Technology
Apollo 8 comes equipped with four Unison-enabled mic preamps, letting you track 
projects with colorful mic preamp sounds from Neve, API, and Universal Audio. An 
Apollo breakthrough, Unison technology nails the tone of these sought-after tube and 
solid state mic preamps — including their impedance, gain stage “sweet spots,” and 
component-level circuit behaviors. 
The secret to Unison is its hardware-software integration between Apollo’s mic preamps 
and its onboard UAD-2 processing. Simply place a selected tube or solid state preamp 
plug-in on your desired mic input, and record in real time through stunning emulations 
like the bundled UA 610-B Tube Preamp plug-in, or the Neve 1073 and API 212L.
Impedance and Gain Matching
Apollo 8 also includes Unison technology on its front panel instrument inputs, giving you 
dead-on emulations of guitar and bass amps like the Fender ‘55 Tweed Deluxe, Marshall 
Plexi Super Lead 1959, and Ampeg B-15N Bass Amplifier, as well as iconic stompboxes.
Improved Monitoring and Workflow
Apollo 8 features a host of front-panel upgrades over the original Apollo, including Alt 
Speakers, Dim, and Mono functions as well as input and output metering capabilities.
Expands Your System
Thanks to Apollo Expanded software, users of Thunderbolt-equipped Apollo Twin, Apollo 
8, Apollo 8p, and Apollo 16 audio interfaces can combine up to four Apollos and six 
total UAD-2 devices — adding I/O and DSP as your studio grows. Apollo Expanded also 
provides seamless integration with previous generation Apollos over Thunderbolt.
A Sleek New App
With Apollo 8’s Console 2.0 application — a complete re-imagining of Apollo’s original 
Console software — you can take advantage of over 25 new user-requested features such 
as Channel Strip presets, Drag & Drop functionality, dynamically resizable windows, and 
more.
