Feedback suppressor AF200

Interview

Product Details

Model: AF200

A: Features

1: It is a stereo or independent dual-channel processing. Digital processing feedback suppressor, using professional 32bit floating point DSP processor to quickly detect and suppress howling.

2: Each channel has 24 programmable filters. Selectable filter release time, filter application type, including: speech filter, low, medium, high, three-stage music filter. Can be set arbitrarily Dynamic and Static Filters

3: 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.

4: The signal can be bypassed and output directly, dynamic filter mode: detection and suppression of real-time feedback. 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.

5: 5 LEDs for each channel indicate the input level, the indicated level is -20dBu, 0dBu, +10dBu, clip.

 6: COG display can choose menu to set filter parameters, notch frequency, and other functional parameters

7: Support optical fiber coaxial digital signal input

B: technical parameter:

Sampling rate: 48KHz

Dynamic range: >109dB, A-weighted; >106dB unweighted; bandwidth 22KHz

Total Harmonic Distortion + Noise: Typical 0.003%, output level +4dBu, 1KHz

Frequency response characteristics: 20Hz-20KHz, ±0.5dB

Inter-channel crossover voice: Typical value>80dB

Crossover voice at the output: Typical value>80dB

Power supply voltage: AC 50/60Hz, 185- 230V,

Power consumption: 9W
