Our verdictWith two preamps and separate front-panel controls, the 2i2 4th Gen accommodates stereo pairs or simultaneous vocal and guitar tracking. Driver efficiency keeps round-trip latency manageable, which counts for more in software monitoring than preamp color. Verify that your tracking needs require two live inputs before paying the markup over the Solo.The fourth-generation Solo updates conversion performance and input controls while maintaining Focusrite's stable driver ecosystem. While latency and dynamic range figures are solid, the higher price tag approaches dual-preamp hardware options. It remains an efficient single-channel interface when driver dependability is the main concern.
Pros and cons
  • Dual independent inputs support stereo microphone setups
  • Consistently low driver round-trip latency
  • Separate level controls for monitors and headphones
  • Substantial price increase over previous generations
  • Requires steady USB-C power delivery from host
  • Reliable driver architecture with low latency
  • Clear front-panel metering indicators
  • Updated conversion performance over previous generation
  • Price approaches dual-input interface alternatives
  • Restricted to a single XLR microphone channel
