MP-FE2 Description The MP-FE2 is a powerful digital feedback detection device .The system is based on the analysis of the frequencies contained into the incoming signal and removes the spectral Larsen lines with 12 hi-precision notch filters per channel. Initial setup is not required. 15 preset sensitivities are available, allowing to reduce or increase Larsen sensitivity. The notch filter setup is memorized in order to be restored when the device is power-cycled. The device has the possibility to be set in terms of sensitivity through the encoder, which passing from the position 1 to the position 15 modifies, decreasing it, the sensitivity of the system lowering the reactivity of it to the feedback detection: the max sensitivity is got with the position 1 of the encoder, and the min sensitivity, with the position15. analog bypass control.
