Focusrite Scarlett 4i4 (4th Generation)

The Focusrite Scarlett 4i4 (4th Generation) is a 4-in/4-out USB-C audio and MIDI interface for musicians, producers, and content creators who need more connections than a two-channel interface. Two 4th Gen mic preamps with 69 dB of gain and Air mode, converters with 120 dB of dynamic range, four balanced outputs, 5-pin MIDI, loopback, and a new standalone mode make it a flexible hub for recording, podcasting, and streaming.

Focusrite Scarlett 4i4 4th Gen: More I/O, Same Great Sound

The 4i4 shares the 2i2’s acclaimed 4th Gen preamps and RedNet-derived converters, and adds extra inputs, four outputs, and MIDI. Connect two pairs of monitors, send signals to outboard effects, and integrate keyboards and synths, all from one compact interface.

Smart Recording Features

Auto Gain sets the perfect level with one press, and Clip Safe reduces gain automatically if a peak threatens to clip. Air mode adds bright, open presence inspired by Focusrite’s ISA preamps.

Setting Up the Scarlett 4i4

Connect the 4i4 to your Mac, PC, or USB-C iPad with the USB-C cable; it’s bus powered. Run Easy Start, plug in mics and instruments, and press Auto Gain. Connect monitors to outputs 1/2, a second pair or headphone amp to outputs 3/4, and MIDI gear to the 5-pin ports.

What to Pair With the Scarlett 4i4

Pair the Scarlett 4i4 with condenser and dynamic microphones, studio monitors, closed-back headphones, a MIDI keyboard, and XLR and TRS cables.

Standalone Mode

The 4i4 4th Gen can pass audio from inputs to outputs without a computer, powered by the included adapter or a USB power bank, handy for live performance or monitoring-only setups.

Built for Creators

Loopback captures audio from other apps on your computer, so podcasters, gamers, and streamers can mix music, calls, and game audio into their recordings and streams.

Software Included

The 4i4 comes with a recording toolkit including entry versions of popular DAWs and Focusrite’s Hitmaker Expansion bundle of plug-ins and instruments.

Scarlett 4i4 vs. Scarlett 2i2

Both share the same preamps and converters. The 4i4 adds extra line inputs, four outputs, MIDI I/O, and standalone mode, while the 2i2 is a simpler 2-in/2-out interface.

Recording Tips

Use Auto Gain at the start of each session, then leave Clip Safe on for unpredictable sources like loud vocals and drums. Route outputs 3/4 to a headphone amp or second speakers so a performer can hear a separate cue mix.
