A difference you will hear.
From the mic preamps to the AD/DA converters and the clocking, Duet is best-in-class and cutting-edge Apogee technology. With components carefully selected in critical listening tests and a highly efficient circuit design, Duet was built by Apogee engineers to make a difference you can hear.

Pristine, next generation AD/DA converters
Duet’s AD/DA converters are designed to deliver the purest recordings and best listening experience possible. Duet’s efficient circuitry and state-of-the-art components provide a simplified signal path resulting in incredibly transparent recordings.

Smooth, detailed world-class mic preamps
Much like the AD/DA converters, Duet’s mic preamps feature the latest components and offer seamless click-free transitions as the gain increases and decreases throughout the incredible range of 0-75dB. This unprecedented feature allows you to dial in the perfect level, either with the controller knob or from within software, while delivering ultra-low noise and smooth, crisp detail. Duet’s mic pres are suitable for all dynamic, condenser or ribbon microphones, allowing you to capture any sound without compromise.

Soft Limit
Soft Limit for protection from digital overs
An Apogee technology first introduced in 1992 on Apogee’s AD-500 converter, Soft Limit can be heard on countless platinum selling records around the world. Once a technology exclusively reserved for Apogee’s most advanced audio converters, Soft Limit is included in Duet and can be enabled in Apogee Maestro software.

This superior analog design prevents the digital clipping that causes distortion by instantaneously rounding off transient peaks before they hit the analog-to-digital converter. Soft Limit allows several more decibels of apparent level to be recorded while subtly providing an analog-like warmth to the sound.

Direct digital connection to iPad
Apogee ONE, Duet and Quartet for iPad and Mac feature special circuitry that makes a direct digital connection to iPad and iOS devices* and is certified by Apple’s MFi (Made for iOS) program.
*Connection to iOS devices with a Lightning port requires the
Lightning to 30-pin Adapter.

DC power charges iPad
In audio, adequate power is essential for excellent sound quality. With a direct digital connection and an external power source, ONE, Duet and Quartet are able to charge your iPad while you record so your work will not be interrupted.

Breakout Cable
Duet’s breakout cable includes 2 combination mic/instrument connectors (XLR and 1/4” built into a single connector) and 2 balanced 1/4” connectors for speakers. The elegant single cable-to-junction design allows for easy cable management and the locking connection to Duet is robust and stylish.

2 Analog Inputs
Duet’s 2 combination input connectors (XLR and 1/4”) allow you to connect microphones, guitars and keyboards or your favorite external mic preamps, compressors and EQs.

4 Analog Outputs
Duet includes 4 analog outputs. 2 1/4” balanced outputs for connection to speakers or outboard equipment and a separate, independently controlled 1/4” stereo headphone output.

With these 4 outputs it’s possible for a DJ to monitor a separate mix in headphones while sending a house mix to the club, a live performer to send a click track to in-ear monitors while sending a backing track to front-of-house, and a recording engineer to send a headphone mix to the performer while dedicating the main outputs to studio monitors.

MIDI
Duet provides a single USB MIDI connection for your CoreMIDI compatible keyboard, synth, or DJ controller. This eliminates the need for an external MIDI interface and promotes an all-in-one music creation solution where Duet and Maestro manage all audio and MIDI. On iPad, Duet’s MIDI connection allows both Duet and a keyboard or DJ controller to be connected at the same time to the iPad’s single 30-pin dock port.

Breakout Box Accessory
Available as a separate accessory for Duet is a solidly built, aluminum breakout box with 2 1/4” inputs, 2 XLR inputs (for 2 simultaneous channels of input) and 2 balanced XLR outputs. The Duet breakout box features studio-quality I/O connectors and includes a 2 meter cable allowing you to extend your input and output connections away from your desktop and minimize cable clutter.
