Eight of our most detailed, ultra-low-noise preamps.
Connect your studio to 18i20’s remote-controlled preamps — Scarlett’s most transparent and detailed ever. 69dB of gain range provides all the headroom you'll need to get the best result from the most intense multi-track recordings.
Auto Gain and Clip Safe.
Let 18i20 handle your levels. Auto Gain will set all eight microphone preamp levels instantly and Clip Safe keeps them in the sweet spot, automatically tweaking the gain if you’re in danger of clipping. You'll never lose a take again.
