The Avid Pro Tools Quartet driver connects your audio interface to Windows so recording software can access its audio inputs and outputs. Installing the appropriate Avid driver helps your computer recognize the Quartet and supports reliable recording, playback, and monitoring in a compatible audio setup.

Key Features

• Audio input and output access: Enables compatible applications to use the Quartet’s recording inputs and playback outputs for microphones, instruments, and connected monitoring equipment.
• Low-latency recording support: Provides the driver connection needed for responsive audio performance in compatible recording software. Actual latency depends on buffer settings, session workload, and your computer.
• Audio configuration: Allows supported software and driver controls to manage settings such as sample rate and buffer size, helping you balance responsiveness with playback stability.
• Windows integration: Supports communication between the Avid interface and the operating system. For Windows 11, 10, 8, or 7, check the individual download’s compatibility notes rather than assuming one driver release supports every version.

How to Install

1. Check your Windows version. Open your system information and confirm the operating system and architecture. Select an Avid Pro Tools Quartet driver package explicitly listed for your configuration, and review any installation requirements.
2. Prepare the computer and interface. Close Pro Tools and other audio applications. Keep the Quartet disconnected unless the installer instructions say otherwise. If replacing an older driver, follow the package’s guidance on whether it should be removed first.
3. Run the driver installer. Extract the download if necessary, launch the setup program, and approve the Windows permission prompt. Follow the on-screen instructions to complete installation.
4. Connect the Quartet. Restart Windows if prompted, then power on the interface and connect it to a suitable USB port. A direct connection to the computer can help avoid issues caused by hubs or adapters.
5. Configure and test your audio software. Select the Avid Pro Tools Quartet as the audio device or playback engine in your compatible recording application. Choose an appropriate sample rate and buffer size, then test playback and an input signal before starting a session.

If the interface is not detected, check its power and USB connection, confirm that the installed driver matches your Windows version, and review the driver’s release notes for known limitations.

Common Issues and Fixes

• Installer fails or stalls: Run the Avid Quartet driver installer as Administrator, disconnect the Quartet until prompted, temporarily disable antivirus, then reboot before connecting the interface.
• Quartet not detected: Use a direct USB port and known-good cable—avoid hubs. Check Device Manager for the Avid/Quartet audio device, then set Quartet as the default playback/recording device and confirm matching sample rate in Windows and Pro Tools.
• Version or ASIO conflicts: Uninstall older Avid/Apogee Quartet drivers via Apps & Features, reboot, and install the latest Windows driver. In Pro Tools, reselect the Quartet as the playback engine and avoid mixing legacy Avid audio drivers.
