What’s New?

The latest firmware for the Scarlett 4th Gen family introduces the following features:

Expanded Connectivity With 16 Channels of ADAT I/O: The Scarlett 18i20 now features 16 channels of ADAT I/O, allowing users to expand from eight inputs and outputs to a total of 16 additional inputs and outputs at 44.1/48kHz over ADAT, enabling a total of 24 inputs and 28 outputs — perfect for live sessions, large recordings and I/O-heavy setups.
Monitor Groups For Flexible Speaker Control: Monitor Groups are now available across the Scarlett 16i16, 18i16 and 18i20, simplifying multi-speaker configurations including 2.1 and 5.1 surround setups. This enhancement gives users greater control over their monitoring workflow, making it easier than ever to switch between different speaker sets.
Remote Multichannel Auto Gain: For Scarlett 18i20 users, Multichannel Auto Gain is now accessible via the Focusrite Control 2 mobile app, allowing users to adjust input levels remotely and eliminating the need for frequent trips to the computer.
