Apollo Twin X DUO USB Heritage Edition — Elite USB-C Conversion for Windows

Universal Audio Twin X DUO USB HE delivers reference-level 24-bit / 192 kHz audio conversion with real-time DSP for Windows-based studios. Next-generation converters and UAD-2 DUO Core processing enable tracking through classic analog plug-ins with almost no latency. The all-metal chassis features hands-on controls for monitor management, preamp selection, and signal routing without tedious menu navigation.

Unison Preamp Technology and DUO Core DSP

Unison technology matches preamp impedance and gain staging to UAD plug-in models of Neve, API, Manley, and Avalon. With onboard DUO Core processing, your system resources are preserved—even during complex mixes—as plug-in emulations run independently of the computer's CPU.

Elite-Class 24-bit / 192 kHz AD/DA Conversion

The advanced converters provide a spacious, lifelike soundstage with extremely low distortion and broad dynamic range. Acoustic details, subtle reverbs, and vocal nuances remain preserved after conversion.

• Sample Rate: 192 kHz / 24 bit — captures ultrasonic harmonics and fits high-resolution workflows
• Dynamic Range: 127 dB on monitor outputs — allows you to discern every nuance in dense productions
• Even when mixing quietly, the THD+N of -117 dB ensures signal purity on all outputs.

Versatile I/O with ADAT Expansion

Combo inputs accept microphones and line sources, while a Hi-Z jack on the front panel is ready for guitars and basses. Expand up to eight additional channels with the optical ADAT input—ideal for larger recording sessions.

• Preamps: 2 Unison XLR/Jack combo with +10 to +65 dB gain and -20 dB pad per channel
• Digital Input: TOSLINK Optical (ADAT / S/PDIF) — supports 8 channels at 44.1/48 kHz and 4 at 88.2/96 kHz
• Connect to your computer with USB-C 3.0 (USB 3.1/3.2 Gen 2).
