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.* 

The Gold Standard in 24-bit/192 kHz 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 analog emulations from Ampex, Lexicon, Manley, Neve, Roland, 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 Distortion, Softube Amp Rooms, 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 these sought-after tube and solid state mic preamps — including their impedance, gain stage “sweet spots,” and component-level circuit behaviours.
