Apollo Twin USB. High-Resolution Desktop Music Production for Windows.

With its class-leading resolution and Realtime UAD Processing, Apollo Twin USB sets the standard for desktop music production for Windows-based systems. This 2x6 USB 3 audio interface allows you to record with near-zero latency through the full range of UAD Powered Plug-Ins — ingeniously merging classic analog tones with cutting-edge features.

Record and Mix with Stunning
24-bit/192 kHz Sound Quality
With the highest dynamic range and lowest noise of any desktop interface, Apollo Twin USB gives you stellar 24-bit/192 kHz sound and breathtaking clarity.
Its premium mic preamps and class-leading conversion translate into rich three-dimensional recordings with exceptional depth and punch. Digitally controlled analog monitor outputs provide full resolution audio at all listening levels — letting you create better mixes in real-world environments.

A Complete Analog Studio with
Realtime UAD Plug-In Processing
Imagine having access to a classic analog recording studio, right on your desktop. Apollo Twin USB lets you record and mix through the full range of UAD Powered Plug-Ins — including vintage EQs, compressors, reverbs, tape machines and more — at near-zero latency, regardless of your audio software buffer size. The key to its analog magic is onboard UAD-2 DUO DSP Processing, which powers the UAD plug-ins while reducing the strain on your host CPU. Apollo Twin USB includes the "Realtime Analog Classics" plug-in bundle.

Track Through Classic Preamps Using
Unison™ Technology
Unison technology allows Apollo’sTwin USB’s mic preamps and front-panel DI to sound and behave like the world's most sought-after tube and solid state preamps, guitar amps, and stompboxes — including their all-important impedance, gain stage "sweet spots," and circuit behaviors. Based on breakthrough integration between Apollo’s analog inputs and its onboard UAD processing, Unison lets you track through a range of colorful emulations from Neve, API, and Marshall with amazing tone.

Professional I/O Connections
Apollo Twin USB is a 2x6 interface with two class-leading mic/line preamps, two analog line outputs, two digitally controlled analog monitor outputs, and up to eight additional channels of digital inputs via Optical connection. Its conveniently located Hi-Z instrument input and headphone jack allow you to capture inspiration the moment it strikes.

A Sleek New App Console 2.0 is Apollo Twin USB’s software control interface. Its intuitive, analog console-style design provides realtime tracking and monitoring with UAD Powered Plug-Ins, Channel Strip presets, Drag & Drop functionality, dynamically resizable windows, and more.

Easy to Use with Any DAW
Apollo Twin USB is compatible with major DAWs, including Pro Tools, Cubase, Ableton Live, and more — allowing seamless integration no matter what recording software you use.
