Universal Audio Twin X DUO USB Overview

Poised to be the center of a Windows-based home studio or mobile rig, the Universal Audio Apollo Twin X USB DUO Heritage Edition is a desktop 10x6 USB-C audio interface that gives musicians and producers elite-class A/D and D/A conversion with the tone, feel, and flow of analog recording.

Offering DUO Core UAD plug-in processing, Unison-enabled mic preamps, and the Heritage Edition suite of 25 award-winning UAD plug-ins—featuring Collections from Teletronix, Pultec, UA, and more—the Apollo Twin X USB DUO lets you record your vocals, acoustic instruments, and electric guitars in real time through classic mic preamp and channel-strip emulations from Neve, API, Manley, Avalon, and more—with near-zero latency.

The Power of Apollo Twin X USB DUO
  • Track, overdub, and mix with high-resolution AD/DA conversion and DSP-powered plug-ins.
  • Onboard UAD-2 DUO Core Processing for tracking in real time through included UAD Heritage Edition plug-ins like the Teletronix LA-2A and 1176 vintage compressors, Pultec EQs, iconic UA 610 tube preamp, tape machines, and guitar amps—with near-zero latency, regardless of audio buffer size.
  • Proprietary Unison technology offers the tone of sought-after classic-tube and transformer-based preamps from Neve, API, Manley, Avalon, and more, plus guitar amps, and stompboxes.
  • USB-C 3.0 connectivity for Windows-based computers.
  • Runs UAD Powered Plug-Ins via VST, Audio Units, and AAX in all major DAWs.
  • Uncompromising analog design, superior components, and premium build quality in a convenient desktop form factor.
  • Reliable AC powering (external power supply included).

  • Furnished with elite-class, next-generation 24-bit / 192 kHz conversion akin to the popular Apollo X rackmount interfaces, the Apollo Twin X USB DUO gives you a spacious, organic sound that easily rivals dedicated high-end converters—with low distortion (-117 dB) and immense dynamic range (127 dB).
Versatile I/O for the Studio
  • The 10x6 audio interface features two Unison-enabled microphone preamps (via XLR-1/4" combo mic/line inputs) for precise UAD emulations of classic analog preamps—impart vintage character of your choosing on microphone and instrument recordings while bypassing the unpredictable nature of old equipment.
