Duet 3 Overview

Apogee Duet 3 USB Audio Interface

The Apogee Duet 3 brings flagship-quality audio conversion and mic preamps into an ultra-compact, travel-ready form. Designed for artists, engineers, and content creators who demand Apogee’s legendary clarity wherever they go, the Duet 3 captures studio-level detail with effortless portability. Drawing on the same AD/DA conversion technology found in the Symphony series, this interface delivers pristine capture and playback—making your vocals sound honest, instruments feel alive, and mixes translate with precision. It’s all powered through a single USB-C connection, with intuitive onboard controls and real-time DSP for smooth, low-latency workflows.

Everything You Need, Nothing You Don’t

With two high-gain mic/line/instrument inputs and balanced TRS outputs via breakout cable, the Duet 3 fits seamlessly into any rig—from desktop setups to mobile sessions. A touch-sensitive multifunction knob gives you hands-on control over levels and monitor switching, while independent headphone and line outputs make critical listening easy. At the heart of it is the ECS Channel Strip, tuned by legendary mixer Bob Clearmountain. Apply EQ, compression, and saturation in real-time via onboard DSP—perfect for shaping your sound on the way in without taxing your CPU.

Built for Creators on the Move

Housed in a low-profile glass and aluminum chassis, the Duet 3 looks as polished as it sounds. Whether you’re laying down vocals in a hotel room or mixing on the plane, this interface fits easily in your backpack without compromising your sonic standard.
