Great sound quality, total portability and onboard DSP.

Legendary sound quality, total portability and onboard DSP all come together in a beautiful new design with the Apogee Duet 3.

In 2007, the original Apogee Duet shattered the expectations of what a home studio interface could be. Professional, personal and portable, Duet revolutionized independent recording and empowered artists and producers with legendary Apogee converters and preamps, and effortless ease of use. Now, the Duet 3 brings next-generation Apogee performance and features to a beautiful ultra-low profile glass and aluminum design. Duet 3 includes built-in DSP and the Symphony ECS Channel Strip for zero-latency recording with FX. Tuned by Bob Clearmountain, the ECS Channel Strip includes presets custom crafted by the legendary mixer so you can dial in a pro recording sound instantly. Ideal for music creation, voice recording, streaming and gaming, you can use Duet 3 with your Mac or Windows workstation in your studio or on the go. Take your Duet 3 to the next level with the sleek Duet Dock (sold separately) for the ultimate ergonomic desktop experience.

Leaders in digital audio recording since 1985
As an industry leader in digital audio technology for over 35 years, Apogee is the choice for top artists and recording professionals on countless Grammy and Oscar winning recordings. This is because Apogee digital audio converters, preamps and plug-ins simply sound amazing.

Hearing is Believing
Achieving pristine sound quality in a digital audio converter requires engineering that artfully pairs AD/DA converters, digital clocking, analog design and power technology. Duet is the result of decades of innovation and expertise, resulting in sound quality unmatched in its class.

With 2x4 channels of legendary Apogee AD/DA conversion, plus two world-class microphone preamps, Duet is the perfect centerpiece for your home and mobile studio. Connect microphones, guitars, keyboard and line level devices to capture every detail. Monitor the full depth and imaging of your sound through two truly-balanced, line-level analog outputs for speakers. And power your headphones with a zero-ohm headphone output for a dedicated headphone mix.

Turn up the mic, not the noise
One of the most critical components for high-quality recordings, the mic pre in Apogee Duet is extraordinary. With an astounding amount of gain and 48k phantom power, you can cleanly and precisely capture any audio source with even the most gain-hungry microphones. And thanks to meticulous Apogee engineering, you’ll keep noise and distortion down, even at higher gain levels.

Plug in to onboard DSP
To capture the best performance, you need the ability to get an inspiring sound quickly and easily. And few things are more distracting than latency when trying to record your best takes. Duet gives you built-in DSP for Apogee FX processing to precisely shape your sound on input giving you great sounding tracks, all while eliminating the delay that can occur when recording.

Zero latency recording with the Symphony ECS Channel Strip
Tuned by legendary mixer Bob Clearmountain, the Symphony ECS Channel Strip plug-in includes EQ, Compression and Saturation controls that let you create the optimal blend of channel FX for tracking vocals or acoustic instruments. Choose from multiple hand-crafted Clearmountain presets and record with zero latency through Duet’s onboard DSP.

Beautiful, outside and in
Sound quality comes first, but elegant design is a close second. After all, you’re always hands-on with control of listening level and mic pre gain, so why shouldn’t the centerpiece of your studio have a high-end look and feel? The Duet multi-function digital controller knob delivers a luxurious feel for dialing in monitor levels and mic pre gain, while also giving the desktop interface style accents backlit with purple LEDs. Perfectly contoured for ergonomic control on your desktop, the low-profile body is topped with scratch-resistant gorilla glass for a modern look and solid feel.

The Duet Breakout cable for the Duet 3 has been redesigned with streamlined connectors and a longer reach. You can keep everything connected and easily tuck it away off your desk for a clean and organized workspace.

Duet Dock—The Ultimate Duet Desktop Experience
Duet set the standard for making music and recording on the go with its small footprint and flexible breakout cable. But when working in your studio, the best way to use Duet 3 is with the Duet Dock (sold separately). The Dock positions Duet at the ideal angle for quick adjustments and meter and function visibility. The rear panel connectors on Duet Dock make it easier to organize and connect your cables to Duet too.
