Focusrite Scarlett Solo 4th Gen is a USB-C audio interface built for singer-songwriters and solo content creators. It provides one XLR microphone preamp and one Hi-Z instrument input, with up to 24-bit/192kHz recording and a 120dB dynamic range.

Score Breakdown

Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Plug in a mic and guitar and let Scarlett Solo 4th Gen bring big studio sound to wherever you make music.
Uses the same converters as Focusrite's flagship interfaces for clean, detailed recordings.
Lifts vocals and guitars to the front of the mix with musical presence and rich harmonic drive.
Records up to 24-bit/192kHz for detailed, modern production quality.
Comes with Pro Tools Intro+, Ableton Live Lite, Cubase LE, and Hitmaker Expansion for recording, mixing, and mastering.
Design and Build Quality
The interface comes in a red finish and connects via USB-C to PC, Mac, or iPad. The listing does not confirm physical dimensions or weight, so portability claims cannot be verified from the source facts.
It includes one XLR mic preamp and one Hi-Z instrument input, along with Air mode for tonal shaping. Build materials are not specified, but the use of flagship-grade converters suggests a focus on internal quality.
Performance in Everyday Use
With a 120dB dynamic range and 24-bit/192kHz resolution, the Scarlett Solo 4th Gen should deliver clean, detailed recordings for vocals and instruments. Air mode adds presence and harmonic drive, which can help tracks sit better in a mix.
A real limitation is the input count: only one XLR microphone and one Hi-Z instrument can be connected at the same time. There is no mention of MIDI I/O or digital expansion ports, so users with larger setups will need a different interface.
