The Focusrite Scarlett 18i20 4th Gen is a robust audio interface designed for mid sized project and professional studios alike and offers some significant improvements over its predecessor, boasting excellent audio quality, comprehensive I/O options, and useful features for streamlining the recording process. Price wise, it is more expensive than the previous generation, but the enhanced features and performance justify the investment. Considering the amount of I/O, flexibility and quality for the price, we feel it is a very strong contender in its class as a mid-range audio interface, bridging the gap between budget interfaces, and the more high-end market whilst still providing a solid all-around interface.

Pros:

  • Great sounding convertors and plenty of I/O options.
  • Convenient Auto Gain and Safe Mode features.
  • Re-worked 'Air' mode with harmonic drive option.
  • Great routing options and control via Focusrite Control 2 software and mobile app.
  • Slick front panel controls and visual feedback.

Cons:

  • DC coupled I/O would have been welcome for synth orientated setups.
