8.8. FEEDBACK KILLER Section
FEEDBACK KILLER is a new section, available only in MIMO88CONF. The new section includes "notch"
type filters with automatic adjustment, whose mission is to reduce the risk of audio feedbacks (or Larsen
effect).
The FEEDBACK KILLER section consists of 2 banks, with 8 automatic filters in each one of them. The 2
banks are independent in terms of settings, operating mode and assigned output.
According to the settings, the FEEDBACK KILLER algorithm continuously analyses the input-output loop
assigned to each bank, detecting in real-time frequencies prone to feedback then automatically
assigning notch filters to these frequencies. Each notch filter is set (centre frequency and attenuation) to
reduce the level of a band of frequencies in order to avoid a feedback effect.
The image shows the bank 1 with 6 of its 8 filters assigned to frequencies that the algorithm has
detected as prone to feedback:
