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%
