The 2-in, 4-out USB interface for musicians and DJs
Scarlett 2i4 is a 2 in / 4 out USB audio interface featuring two award-winning Focusrite pre-amps and four high-quality audio outputs. Housed in a rugged, anodised aluminium unibody chassis, the Scarlett 2i4 is the perfect audio interface for musicians and digital DJs and can fully withstand the rigours of the road.
Ready to make music!
Connect Scarlett 2i4 to your computer and get ready to make music! With the very best in digital audio technology and a great selection of input and output options, the Scarlett 2i4 will capture and play back your sound with superb quality.
Plug straight in
The front panel has two combo XLR inputs to connect microphones, guitars and line level signals such as keyboards, safe in the knowledge that your sound is in the best possible hands. Use the “PAD” function for high-output guitars or microphones, and use the “DIRECT MONITOR” control for a low-latency mix of input and playback signals.
Checking your levels
Scarlett’s unique “signal halos” let you know that you’ve got the right audio level for recording. Green is good, while red means that your audio is too loud and you need to lower the gain control.
DJ-ready outputs
With 4 RCA outputs, a large, tactile main monitor level control and a high-level headphone output with its own volume control – along with pristine audio quality, in a package ready for the road – Scarlett 2i4 is ideal for today's digital performers and laptop-based DJs.
Polish Your Mix
All Scarlett audio interfaces include Ableton Live Lite recording software, plus two powerful software plug-ins: Red Plug-in Suite and Scarlett Plug-in Suite.
Red 2 & Red 3 Plug-In Suite
The Red Plug-in Suite accurately models our classic Red 2 equaliser and Red 3 compressor, to bring the sound of the famous original hardware to your music software.
Scarlett Plug-In Suite
Scarlett Suite is a professional plug-in suite that provides a definitive suite of compression, gating, EQ and reverb, for tracking and mixing your music.
