Apollo FireWire. High-Resolution
Music Production with Classic Analog Sound.

Apollo FireWire is one of the world’s most popular professional audio interfaces — delivering the sound, feel, and flow of analogue recording to music creators everywhere. A perfect centrepiece for studios running original Mac Pro towers and Windows 7 machines, this 18 x 24 FireWire 800-equipped interface features analogue design based on UA’s 50-year heritage, along with gold-standard Apollo A/D and D/A conversion for impeccable audio resolution.

Apollo FireWire further distinguishes itself with Realtime UAD-2 Processing and Unison™ technology, letting you record with near-zero latency through the full range of UAD plug-ins from Neve, Studer, Manley, Lexicon, and more — including new mic preamp emulations from Neve, API and Universal Audio.*

Sound Quality

Designed to play a central role in studios running original Mac Pro towers or Windows 7 machines, Apollo FireWire delivers an uncompromising approach to audio quality. Building upon decades of UA hardware heritage, it offers extremely high-resolution sound, with the lowest THD and highest dynamic range in its class. Apollo FireWire’s four premium mic preamps and converters translate into recordings with astounding accuracy and depth — whether you’re tracking and overdubbing, or mixing and mastering.

Realtime UAD Plug-In Processing for

Tracking, Mixing, and Mastering

While Apollo FireWire’s “natural” sound is exceedingly open and transparent, it can quickly deliver a wide range of classic analog tones and color via its Realtime UAD Processing. Featuring powerful onboard QUAD processing, Apollo FireWire’s DSP Acceleration allows for recording through UAD Powered Plug-Ins — with sub-2ms latency, regardless of buffer settings — letting you monitor and “print” audio with classic analogue emulations from Ampex, Lexicon, Manley, Neve, Marshall, SSL, Studer, and more.* The Apollo FireWire’s bundled “Realtime Analog Classics Plus” suite of UAD plug-ins gives you the UA 610-B Tube Preamp & EQ, Raw Distortions, legacy LA-2A, 1176, and Fairchild compressors, Pultec EQs, and more, so you have a rack full of bonafide audio classics, right out of the box.

Four Mic Preamps with Unison™ Technology

Apollo FireWire comes equipped with four Unison-enabled mic preamps, letting you track with colorful mic preamp sounds from Neve, API, and Universal Audio. An Apollo breakthrough, Unison technology nails the tone of this sought-after tube and solid state mic preamps — including their impedance, gain stage “sweet spots,” and component-level circuit behaviours.

Track With Unison™ Technology

Elegant Hardware Design and Workflow

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.

One key feature of Apollo FireWire isn’t really a “feature” at all. It’s the numerous design details that give you a fast, natural workflow — and better results. There are physical front panel controls for all the most commonly used features, including Preamp and Monitor level knobs, channel selection, mic pad and low cut, phantom power, and dual headphone outs with independent level control. Smart Hi-Z inputs on the front panel detect when you've connected your guitar or bass. Sonically, Apollo's Monitor outputs are digitally controlled analogue, so you don't lose audio resolution when you adjust gain.
