User Interface - IMG STAGE LINE MFE-212 Bedienungsanleitung

The MFE-212 is a feedback remover dual mono device. The system analyzes
frequencies contained in the input signal, removing the Larsen using 12 real-time
high precision notch filters with -45dB attenuation. Sensitivity is adjustable in 15
steps, allowing the user to enhance or reduce Larsen reactivity. The 12 notches per
channel remain saved in RAM memory and can be saved into a user preset. If they
are not saved, switching off the device will reset the filter configuration to the last
saved one. There are 4 factory presets and 16 user presets.
The product has a bypass control in the analog domain and can be linked to
external controllers through USB/MIDI.
