Audient iD4 MkII
Ranked #2 in Best Audio Interfaces

3 sources$195as of Jul 31

The Audient iD4 MkII packs professional performance into a compact desktop box with an all-metal shell. Reviews cite a -114.8 dB A-weighted noise floor and 115.0 dB of dynamic range. The complaints are physical: the volume knob feels flimsy, and volume settings reset every time you power cycle. It also skips the input monitoring hardware its sibling, the iD14 MkII, includes. Solo recording setups are a good match; anyone wanting more advanced monitoring features will be disappointed.

Strengths
  • All-metal construction with solid heft and professional appearance
  • Excellent technical performance with low noise floor (-114.8 dB A-weighted)
  • Good dynamic range (115.0 dB A-weighted)
Watch-outs
  • Volume knob feels less robust compared to other models
  • Volume level does not persist between power cycles
  • No input monitoring on hardware (unlike iD14 MkII)

The Focusrite Scarlett 2i2 4th Gen refreshes the design with better build quality and adds Auto Gain plus updated gain halos. Audio Science Review dug into the DAC and found real problems, including distortion that decreases as internal volume rises in a way it shouldn't. ADC input saturation at 1.7 volts and a subpar headphone output narrow its appeal further. Beginners who want an entry-level interface with friendly features will get along with it, but professionals can do better elsewhere.

Strengths
  • Includes Auto Gain feature for beginner-friendly automatic gain adjustment
  • Features updated Dynamic Gain Halos that visually indicate input levels
  • Provides dedicated XLR inputs on the back panel for condenser microphones
Watch-outs
  • DAC distortion performance is below expected standards according to Audio Science Review
  • ADC input saturation occurs at 1.7 volts, limiting dynamic range

How they stack up

Audient iD4 MkII

The Audient iD4 MkII offers excellent technical performance with a low noise floor and good dynamic range, surpassing the Focusrite Scarlett 2i2 4th Gen and Behringer UMC22 in these areas. However, it lacks the analog preamp features of the Universal Audio Volt Series and the specialized podcasting capabilities of the Focusrite Vocaster Two, making it more suitable for solo recording setups rather than multi-mic tracking or podcasting.

Focusrite Scarlett 2i2 4th Gen

Unlike the Focusrite Vocaster Two, which is tailored for podcasters, the Scarlett 2i2 4th Gen focuses on beginner-friendly features like Auto Gain and visual gain halos, making it more approachable for newcomers. However, it falls short compared to the Universal Audio Volt Series in terms of analog preamp quality and UREI 1176 compression models, and it's also outperformed by the Audient iD4 MkII in technical specs like noise floor and dynamic range.
