  • That said, many people keep their interfaces in a permanent place on their desk. So having the XLR cables run behind the device certainly helps with cable management. But I can also appreciate wanting the XLR ports on the front.

    · 2023
  • The Scarlett 2i2 (4th Gen) is an incredibly popular audio interface. High-quality mic pre-amps aside, the 4th Gen offers a few handy features like Clip Safe, which automatically adjusts your levels on the fly to prevent you from getting into the red and distorting, and Air...

    MusicTech.blog
  • The 2i2 supports both mono and stereo direct monitoring, switchable via a front-panel toggle. In stereo mode, input 1 appears in the left channel and input 2 in the right — useful for recording stereo sources or for hearing a stereo playback mix accurately while tracking.

    MusicTech.blog
  • On Windows, the Focusrite USB ASIO driver is stable, well-maintained, and achieves low latency at modest buffer sizes. At 128 samples, round-trip latency is typically 6–8 ms — low enough for comfortable real-time monitoring through the DAW.

  • [2i2] We’d prefer combi inputs

    Guitar World
  • [4i4] Only two mic preamps

    Guitar World
  • 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
  • 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.
