Apogee Duet 3 – 2×4 USB-C audio interface with best-in-class AD/DA conversion, world-class mic preamps, and built-in DSP for zero-latency recording with Symphony ECS Channel Strip effects. Featuring a sleek low-profile design with an aluminum body and glass top, a multifunction LED-lit control knob, and full compatibility with macOS and Windows, Duet 3 is the perfect centerpiece for both mobile and studio setups.
Building on the legacy of the original Duet, this next-generation model delivers unmatched sonic quality and versatility. With two inputs and four outputs, you can record vocals, instruments, and guitars in pristine detail. The built-in DSP processor enables real-time use of the ECS Channel Strip—crafted by legendary mixer Bob Clearmountain—offering EQ, compression, and saturation with zero latency. Apogee Control 2 software and Channel FX plugin allow you to manage settings directly from your DAW.
Duet 3 isn't just about sound—it's also about form. The scratch-resistant glass surface, ergonomic low-profile build, and backlit knob make it a visual and tactile centerpiece of your workspace. And with the optional Duet Dock, you can elevate your setup with better cable management and desktop ergonomics.
