Xound 2014/6
“An interesting tool for live applications which is able to solve various tricky feedback problems. No matter whether for a monitor or for FOH, the controller MFE-212 delivers a great performance. There is no perceivable difference in sound when switching to bypass mode, i.e. the controller provides a clear and precise sound performance.”
