Critic Reviews

Focusrite Scarlett 18i20 4th Gen review

musictech.com

While the Focusrite Scarlett 18i20 4th Gen audio interface brings robust features and improved audio quality, it isn't without its drawbacks. The intuitive design and enhanced preamps make recording a breeze, especially with features like Auto Gain and Clip Safe. However, the price hike compared to its predecessor and limited ADAT channel support may deter budget-conscious musicians. Overall, it’s a solid investment for serious producers, but potential buyers should weigh the cost against their specific needs.
