What is latency?

Scarlett 2nd Generation interfaces have lower latency than any other USB audio interfaces. Take a look at this short video to see for yourself how latency can cause problems when recording, and find out what you can do to overcome it.

Guitar and Microphone

Sound Like You

Easily make studio-quality recordings that sound just the way you intended. Record anything you want using two combination inputs, with natural-sounding Scarlett mic preamps, 48v phantom power, line level inputs and newly-designed instrument inputs that can handle even the loudest guitar pick-ups.

The Performer's Interface

Four analogue outputs, MIDI I/O and cue mixing make Scarlett 2i4 ideal for live performances. It also gives you a loud headphone output, two balanced outputs and four RCA outputs for connecting to your speakers or mixer.

Recording a Duo?

If you want to record two artists at once, or you’re a multi-instrumentalist who wants to connect mics, instruments and line level gear, take a look at Scarlett 6i6. It has twice as many analogue inputs as Scarlett 2i4 and two separate headphone outputs.

Sam Smith

Used By the Best

What do Sam Smith, Foo Fighters and Massive Attack have in common? Not a lot, admittedly, but they all use Focusrite equipment because they agree with us that sound is everything.

Foo Fighters

Find the Perfect Level

Setting the perfect level couldn’t be easier, thanks our unique haloes around the gain knobs. They glow a reassuring shade of green when you’re recording at the perfect volume. If they turn red, it’s time to back off.
