  • Apollo 8 is the world’s most acclaimed professional recording interface for Mac and Windows, giving project and commercial studios superior A/D and D/A conversion with the tone, feel, and realtime workflow of classic analog recording.

    Built upon UA’s 60-year heritage of audio craftsmanship, Apollo 8 distinguishes itself with four Unison™-enabled mic preamps, UAD-2 QUAD or DUO Core processing, and an included bundle of award-winning UAD plug-ins — which you can track through with near-zero latency, shaping sounds like a classic analog studio — without taxing your host Mac or PC.

    Next-Generation Apollo A/D and D/A Conversion
    Apollo 8 improves upon the original Apollo’s gold-standard audio quality with completely redesigned, class-leading A/D and D/A conversion — giving you increased dynamic range and even lower THD. This results in breathtaking clarity, depth, and accuracy in your recordings, from tracking and overdubbing, to mixing and mastering.

    Realtime UAD Plug-In Processing for Tracking, Mixing, and Mastering
    While Apollo 8’s “natural” sound is very open and transparent, it can quickly deliver a stunning range of classic analog tones and color via its Realtime UAD Processing. Available with UAD-2 DUO processing onboard, Apollo’s DSP Acceleration allows for recording through UAD Powered Plug-Ins — with as low as sub-2ms latency — letting you monitor and “print” audio using classic analog emulations from Ampex, Lexicon, Manley, Neve, Roland, SSL, Studer, and more.

    Using Apollo, UAD plug-ins are also available during mixing and mastering, putting UAD plug-ins (VST, RTAS, AU, AAX 64) at your disposal throughout the creative process.

    Included Plugins:

    • UA 610‐B
    • Marshall Plexi Classic Amplifier
    • Fairchild 670 Legacy
    • Teletronix LA‐2A Legacy
    • UA 1176LN Legacy
    • UA 1176SE Legacy

    Four Mic Preamps with Unison™ Technology
    A Universal Audio breakthrough, Apollo 8’s Unison technology gives you the tone of the world's most sought-after tube and solid state mic preamps — including their impedance, gain stage “sweet spots,” and component-level circuit behaviors.

    Based on unprecedented hardware-software integration between Apollo’s mic preamps and its onboard UAD plug-in processing, Unison lets you record through stunning emulations like the bundled UA 610-B Tube Preamp plug-in, or exclusive preamp emulations from API and Neve.

    Unison technology is further enhanced in Apollo 8 to include its panel Hi-Z instrument inputs, giving you dead-on impedance and gain matching for new stompbox models.

    Apollo Expanded and Console 2.0
    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 their studio grows. Apollo Expanded also permits integration with previous generation Apollo over Thunderbolt.
    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 user-requested features such as Channel Strip presets, Drag & Drop functionality, dynamically resizable windows, and more.

    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 via the new Meter button. These features combine with Apollo’s system scalability to make it the new standard in professional multi-channel audio recording.
