model: FB1000

A: Features

⊙It is a stereo digital feedback suppressor, which adopts professional DSP processor to quickly detect and suppress howling.

⊙ Each channel has 24 LEDs, representing 24 filters, that is, 24 monitoring points. When the light is on, it means that the feedback signal has been detected and the filter has been used. When the light is flashing, it means that the feedback signal is not detected or is being detected, and the filter is not used.

⊙ The signal can be bypassed and output directly, dynamic filter mode: real-time feedback detection and suppression. A dynamic filter continuously updates the filter position. In the dynamic filter mode, the current dynamic filter can be cleared and the light will be off.

⊙ The choice of music and voice notch filter is used to change the notch filter of two channels. In the application mode, through music and voice, the Q value of the notch filter can be changed (equivalent to changing the bandwidth) to achieve the desired effect.

⊙ Each channel has 4 LEDs to indicate the input level, and the indicated level is -10dBu, 0dBu, +10dBu.

⊙ The input level can be switched between +4dBu and -10dBu, which can be used to increase or decrease the input signal.
