The Befaco I4 is a seriously useful module for anyone wanting to bring external instruments or mics into their modular system.

Frequently Asked Questions
It's a solid performer – not as high-end as some boutique preamps, but definitely a step above basic utility modules, offering a balanced and relatively transparent sound.
Generally, no. Ribbon mics are often sensitive to phantom power, and while the I4 has a switch, it's best to avoid using it with ribbons to prevent damage.
The range is adequate, but very slow signals can be challenging to capture effectively; experimentation with the threshold setting is crucial.
