Audient EVO 4 vs Audient iD4 MKII: Which USB-C Audio Interface is Right for You?

The Audient EVO 4 and the Audient iD4 MKII are both USB-C audio interfaces designed to cater to the needs of musicians, podcasters, and other audio professionals, but they serve slightly different purposes and come with distinct features.
The Audient EVO 4 is designed with simplicity and ease of use in mind. It features two EVO preamps, a JFET instrument input, and Smartgain, which automatically sets levels for you. The EVO 4 also boasts a high-performance 24-bit/96kHz AD/DA converter, ensuring high-quality audio recording and playback. Its intuitive control system includes a large multifunction knob and LED metering, which makes it user-friendly even for beginners. Additionally, the EVO 4's loopback functionality is ideal for podcasters and live streamers, allowing you to capture computer audio alongside your microphone inputs.
On the other hand, the Audient iD4 MKII is built for those who demand higher quality and more professional features. It comes with one Audient Console Mic Preamp, the same found in their high-end consoles, and a Class-A JFET instrument input. The iD4 MKII ups the ante with a 24-bit/96kHz AD/DA converter and dual headphone outputs, making it perfect for collaboration. One of its standout features is the ScrollControl, which turns the volume knob into a virtual scroll wheel for adjusting DAW settings and plugin parameters. The iD4 MKII also includes a balanced speaker output and zero-latency monitoring, ensuring seamless recording sessions.
In summary, the EVO 4 is geared towards those who need a straightforward, high-quality recording solution with smart features like auto-gain and loopback, making it ideal for solo musicians and content creators. The iD4 MKII, however, is designed for professionals who require superior preamps, extensive monitoring options, and more advanced control features, making it suitable for serious recording artists and producers.

In terms of box dimensions, the EVO 4 measures 6.8 x 3.85 x 3.55 inches, making it more compact compared to the iD4 MKII, which has dimensions of 7.5 x 6 x 3.5 inches. The larger box dimensions of the iD4 MKII suggest that it may have a larger physical footprint or include more accessories within the packaging.
Both interfaces are designed to be portable and user-friendly, but the EVO 4's lighter weight and smaller box dimensions might make it a more convenient option for users who prioritize portability and space-saving. Conversely, the iD4 MKII's slightly heavier weight and larger dimensions might reflect a more robust build and potentially more features, appealing to users who don't mind the additional size for potentially enhanced functionality.
