Features We Love:

Capture Your Performance

The Scarlett 18i8 features four combination inputs and four line-level inputs. This allows for various recording combinations, which for example could include four singers with two digital pianos recorded in stereo, two musicians each with one vocal and a guitar, or a podcast setup with four people talking and two stereo sound sources. Singers can also take advantage of the Air mode which adds some high end definition to the tone of your microphone.

It is also possible to add an additional eight inputs to the 18i8 via an ADAT expansion rack like the Focusrite OctoPre Dynamic


With four line-level outputs, the 18i8 can be an essential part of your stage and studio setups.

In the studio, 18i8 could be used to send mixes to two pairs of monitors, or a mix to one pair of monitors with the other two outputs being used for FX sends where they're fed into two separate stereo effects units, returning to the four line-inputs

On stage 18i8 can be used for sending multitrack stems to the PA, for example, you could have a backing track with bass, keyboards and backing vocals, each individually sent to the PA to be mixed by the engineer, and use the fourth output for a clicktrack which is sent to your drummer's headphones.

18i8 is also a great option for DJs using software, where each virtual deck is sent from the line outputs to an analogue DJ mixer.
