“These converters operate up to 24-bit / 96kHz and deliver up to 120dB of dynamic range. This is certainly more than enough resolution for the artist working from home, and easily enough for those using the interface for streaming, podcasting, or other content creation.”
How-To Geek· Kris Wouk2023
“Testing at 96k — Hz revealed excellent transient response on drum recordings. The 192kHz option provides additional headroom for professional post-production, though 96kHz proves sufficient for most home recording whilst conserving hard drive space.”

— MusicRadar
Further new features are specific to the 2i2 and 4i4. The reworked preamps have an impressive 69dB of gain, which we found ideal for low-output mics such as ribbons. The 2i2 and 4i4 preamps also include optional auto gain and clip safe.
— MusicRadar
Although it’s probably not at the top of anyone’s list when choosing an audio interface, I couldn’t help but remark that they both look super slick. The red has a metallic sparkle to it and everything feels nice and solid, with the knobs feeling firm when you turn them.

Another useful feature new to the 4th generation Scarlett 2i2 is the extra optional USB power socket. This makes the 4th gen 2i2 suitable for use with devices that don’t have the sufficient power for it, like an iPhone or iPad.

Criticised6

This now has two stages of enhancement - presence or presence with harmonic drive. We found the latter was ideal for livening up vanilla DI electric guitar or bass. The only downside is the Solo unit can only apply Air to the mic input and not the instrument input.
— MusicRadar
[2i2] We’d prefer combi inputs
— Guitar World
[4i4] Only two mic preamps
— Guitar World
Perhaps Focusrite could’ve gone one step further and allowed you to plug in 4 cables at a time, with a selector to choose which ones are active. It would certainly cut down on the amount of plugging in and unplugging.
— SOUNDREF
The 2i2 tops out at two simultaneous inputs — one XLR mic and one instrument, or two XLR mics via the two combo jacks.
— MusicTech.blog
The 2i2 also has no MIDI I/O — if you need to connect hardware synthesizers or drum machines via traditional five-pin DIN MIDI, you’ll need either a separate MIDI interface or a different audio interface that includes MIDI ports.

How to Choose

Why USB Audio Interfaces Matter: Research-backed Benefits

Multiple lines of research in audio engineering and psychoacoustics support the practical benefits of using quality USB audio interfaces. Studies and industry standards show that better analog-to-digital conversion and low-noise preamps lead to clearer recordings, improved dynamic range, and easier post production. Research into latency perception demonstrates that low round-trip latency improves performer timing and comfort, which is especially important for tracking and live collaboration. Practical testing and controlled measurements published by audio engineering groups confirm that well-designed interfaces provide more consistent results than generic onboard sound devices.

Low-latency performance: Studies show latency below roughly 10 ms is generally imperceptible to performers, improving timing and feel during recording sessions.

High-quality A/D conversion: Better converters reduce distortion and improve dynamic range, yielding cleaner recordings that stand up to mixing and mastering.

Microphone preamp fidelity: Research and objective measurements highlight the value of low-noise preamps for capturing detailed transients and lower noise floors.

Sample rate and bit depth: Using 24-bit/96 kHz or higher captures more detail and headroom, which benefits editing and processing even if final delivery is lower resolution.

Usability and workflow: Human factors studies emphasize that intuitive controls, reliable drivers, and clear metering reduce setup time and errors, boosting creative focus.
