The Duo can be used with the Sound Manager on the Macintosh, or with the
Windows Sound System in Windows, and therefore can operate as your system
sound card. If your software is ASIO or EASI compliant, such as Steinberg’s
Cubase or Emagic’s Logic, we suggest using the ASIO or EASI drivers. These
drivers will allow you to monitor audio through your music program with greatly
reduced latency. The WDM drivers that are used in Windows ME, 2000, and XP
will give you similar monitoring capability when using a music program that
takes advantage of them, such as Cakewalks’s
Sonar.
Hardware & Software Installation on the PC
Here is a simple, step-by-step procedure for attaching and powering up the Duo.
See the section, “ASIO/EASI Operation” for information on configuring ASIO
or EASI drivers.
1. Plug the Duo wall-wart into your wall receptacle and to the Duo 9vAC power
jack. Use only the included power supply, or a similar power supply with the
exact same specifications.
2. Connect the USB cable to your computer and the Duo (one end of the cable is
for the computer, and the other is the device end). Find an appropriate spot on
your desktop or work area for the Duo.
Windows XP Installation
1. Boot Windows XP with your M-Audio USB Duo powered OFF. After
Windows XP has been booted, power up the Duo.
2. Windows XP will then detect and automatically install the drivers for the USB
Composite Device and USB Audio Devices.
3. Insert the included Driver CD into your computer’s CD drive. Assuming that
your CD drive is the “D” drive, locate the Duo driver at

4. Run the program “Duo XP PostInstaller” program by double clicking on it.
This will install the Duo’s Windows MME drivers, plus the ASIO and EASI
drivers.

"Continue Anyway."
5. Restart the computer after the installation is finished.
Windows 2000 Installation
