Marani DFP110 Rackmount Feedback Elliimiinator

DFP-110 Description The DFP-110 is a feedback detection device performing a Feedback detection based on the Dynamic Band Scanning and High Precision Notch Filters Automatic placement. It can be used in dual channel, or mono mode. The feedback system, suitable mainly for ¡Musical¡applications, analyzes all frequencies in the signal path, determines the cause of the Larsen effect and cancels it by implementing the 12 real-time high precision notch filters up to -45dB attenuation each one. The system is adjustable in 15 steps, allowing the user to change the DFP-110 sensitivity to ¡audio feedback¡according to situation requirements. The parameter settings of the 12 notch filters per channel remain in EEprom memory and will be recalled after powering ¡OFF¡and ¡ON¡again the unit, until the user will decide to change the settings. These values will be updated and changed as soon as the variation potentiometer is moved. The DFP-110 unit has bypass circuitry designed within the analog domain for quick and easy system wiring.The DFP-110, due to its way of operating based on the feedback elimination based on Notch filters,removed after the feedback has been eliminated, is not alterating the original signal band, making it particularly suitable for ¡Musical¡applications.
