  • Feedback Suppressor FX1210 2025-03-03 Feedback suppression frequency shifter (12 independent digital notch filters per channel, automatically controlled from 40Hz-20KHz)


    Filters: 12 independent digital notch filters per channel, ranging from 40Hz to 20KH

    Automatic control of filter bandwidth: Users can control it, or it can be 1/10 octave band,

    Or 1/5 octave band, constant Q value, resolution 1Hz

    Time required to search for and eliminate feedback: 0.4 seconds, typical value 1KHz

    The number of active filters and fixed filters per channel is selectable by the user, and the final configuration is stored in memory

    Activity filter timer: The release time of the activity filter is 1, 5, 30, or 60 minutes

    Input/Output: Maximum signal level for input/output: Balanced input/balanced output 27dBV, peak value,

    Unbalanced input/output 21dBV, peak value

    Output driver: The unit is designed to drive a load with a resistance greater than 600 Ω

    Input impedance: Balanced or unbalanced input impedance>40K Ω, 2-pin high level

    Output impedance: Balanced or unbalanced input impedance of 150 Ω, 2-pin high level

    Side pass: Real power off side pass

    Peak space: Typically 4dBV balanced input, with a maximum peak of 23dB

    I/C connector: XLR-3 and 1/4 "TRS

    Frequency response: 20Hz~20KHz, ± 0.3dB

    Gain matching: ± 0.2dB

    Spectrum changes: 0.25dB,20Hz~20KHz

    Signal/Noise Dynamic Range:> 100dB

    Total harmonic distortion: 0.005%, 1KHz; 20Hz~10KH,< 0.01%,10KHz~20KHz,< 0.025%

    Dynamic range:> 105dB
