With its speaker-switching technology, the Scarlett 18i20 gen 3 also allows you two to switch between two different sets of monitors. This is an essential feature to ensure the best possible mix and professional level results.

With two independent headphone outputs, both the engineer and recording artist can monitor during the session.

In fact, there’s also a new built-in talkback microphone in the Scarlett 18i20’S front panel so you can easily communicate with the recording artist from behind the glass.
