Digital Feedback Eliminator DFP-212
Description
The DFP-212 is a powerful digital feedback detection device that can be used in dual channel, stereo or mono mode.
The DFP-212 has been carefully designed to seamlessly protect audio events from feedback problems that can occur between loudspeakers and open microphones. The system can be set up for automatic detection, or be configured manually and according to user settings. The feedback system analyzes all frequencies in the signal path, determines the cause of the Larsen effect and cancels it by implementing up to 24 real-time high precision notch filters that have - 45dB attenuation. The system is adjustable in steps, allowing the user to change the GFE- 2 sensitivity to audio feedback according to your situation requirements. The parameter settings of the 24 notch filters per channel remain in RAM memory, but if it is required to keep them as a setting for future reference they must be saved in a user memory preset.
The DFP-212 has 20 memories available, with 4 factory presets and 16 user memory presets.The unit can be connected via Rs485, RS232 as well as USB for external control and two way movements of data.
