The Focusrite Scarlett 18i20 driver connects your USB audio interface to Windows so recording software can access its audio inputs and outputs correctly. Installing the appropriate Focusrite driver helps deliver stable playback, multichannel recording, and responsive monitoring when working in a digital audio workstation (DAW).

Key Features

• ASIO support for recording software: Allows compatible DAWs to communicate directly with the interface, with adjustable buffer settings to balance latency and system performance.
• Multichannel audio access: Makes the Scarlett 18i20’s available recording and playback channels accessible to compatible applications for sessions involving microphones, instruments, and external audio equipment.
• Audio configuration options: Works with the appropriate Focusrite control software for your hardware generation to manage supported settings, such as sample rate, routing, and monitor mixes.
• Reliable USB communication: Provides the device-specific connection Windows needs to recognize and operate the interface properly.

How to Install

1. Identify your Scarlett generation and Windows version. The Scarlett 18i20 has multiple hardware generations with different software requirements. For Windows 11, 10, 8, or 7, verify that the selected package explicitly supports both your operating system and your interface generation; one installer may not cover every combination.
2. Download the matching Focusrite software package. Depending on the model, the driver may be included with its compatible control application. Check the package instructions before starting.
3. Close audio applications and run the installer. Accept any Windows permission prompts and follow the setup instructions, including guidance on when to connect or disconnect the interface.
4. Finish setup and connect the hardware. Restart Windows if requested, power on the Scarlett 18i20, and connect it to a suitable USB port, preferably directly rather than through a hub.
5. Select the interface in your audio software. Choose the Focusrite ASIO driver in your DAW, enable the required channels, and test recording and playback. If you hear clicks or dropouts, try increasing the buffer size before recording a full session.

Common Issues and Fixes

• Installer fails or stalls: Disconnect the Scarlett 18i20, close Focusrite Control and any DAW, run the installer as administrator, then reconnect only when prompted. Use a direct USB 2.0 port, not a hub.
• Device not detected: Confirm the 18i20 is powered and selected in Focusrite Control. Try a known-good USB cable/port, disable USB selective suspend, and check Windows microphone/privacy access for audio apps.
• Driver/version conflicts: Uninstall older Focusrite USB drivers and Focusrite Control, reboot, then install the latest package for your 18i20 generation. Avoid mixing beta and release versions; roll back via Device Manager if needed.
