Apogee Duet USB Audio Interface for iPad and Mac

Two-in, four-out studio-quality interface, now with iOS support

Product Description

The Apogee Duet is a two-input, four-output USB audio interface with pristine-sounding preamps and mastering-grade digital audio converters. Perfect for musicians, producers and engineers on the go, Duet offers world-class sound in a portable package. Paired with an elegant interface and an intuitive software controller, Duet makes it easier than ever to create studio-quality recordings anywhere you go.


Duet packs a surprising amount of connectivity in its sleek, compact interface. Connect microphones, guitars, line-level instruments and even analog signal processors using two combination line/mic/instrument inputs on the included breakout cable. Each input offers selectable 48 V phantom power for connecting condenser microphones. A soft limiter keeps recordings from peaking, while the phase invert option keeps your stereo recordings in check. Capture your recordings using two cutting-edge microphone preamps with up to 75 dB of gain.

Duet is equipped with four analog outputs, two balanced line outputs and a separately controlled 1/4-inch stereo headphone output. With so many monitoring options, recording engineers can create a separate headphone mix for performers while tweaking the mix on the main monitors.


Duet features an intuitive interface with two configurable touchpads and a multi-function controller knob. The touchpads can be programmed to “Mute Outputs”, “Dim Outputs”, “Sum to Mono” or “Toggle Headphone Source” using Apogee’s Maestro 2 software. The controller knob allows you to quickly toggle through inputs and outputs, adjust mic gain, and set output levels. The full-color OLED display delivers visual feedback for a variety of functions.


Compatible with Mac, Windows, and iOS devices, the Duet helps you capture your creativity whenever inspiration strikes. With a compact footprint and a durable design, Duet fits neatly on your desktop, or safely in the bottom of your bag for world-class recording and monitoring anywhere you go.


Windows 10 compatibility is now standard for the latest generations of ONE, Duet and Quartet USB audio interfaces. Customers who purchase the latest generation of these products will be able to register and download a Windows 10 compatible software installer from Apogee’s website. Existing customers will also have access to the download.

The Windows software installers will include a firmware update for the hardware, custom Apogee ASIO audio driver and PC compatible version of Apogee’s Maestro application for controlling audio interface settings and low latency monitoring. All the same functionality currently available to Mac and iOS users will be available to Windows 10 users and the same interface can be used on either Mac, PC or iOS.


  • 2 analog inputs with world-class mic preamps and selectable 48 V phantom power for connecting microphones, instruments or line-level devices.
  • 4 analog outputs - 2 balanced 1/4” outs for speakers or outboard gear, 1/4” stereo headphone output.
  • USB 2.0 High Speed connection to Mac.
  • Direct digital connection with iOS devices
  • (iPhone, iPad and iPod touch. Lightning and

This unit has Upped' my game! Quiet, Crisp and Versatile! It has many useful features.

By Velvet P on June 30, 2020

As far as I know, Apogee hasn’t come up with a cable to connect to the newer Thunderbolt iPads yet, so you can’t access the software to modify parameters when using the Duet with an iPad, which is quite annoying. Everything else is great.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
