There are many debugging methods for feedback suppressors in line array speaker systems, and the operation methods for different machines are also different. There are also many ways to connect the feedback suppressor. Here, we will introduce the simplest and most commonly used method, that is, the microphone signal to the feedback suppressor, the feedback suppressor to the mixer, and the mixer to the power amplifier.
After the wiring is completed, first put the feedback suppressor in the straight-through position (that is, the feedback function does not need to be turned on first), and the latter 48v can be turned on if necessary, otherwise it must be turned off.
Next, the gain setting is performed. The initial setting of the input and output of the feedback is placed at the 12 o'clock position. Generally, there is no need to adjust it. If the system noise is large, the output volume can be reduced. If the system volume is not enough, the subsequent input gain can be appropriately increased. The rear gain can be as large as possible under the premise of distortion (that is, clipping, etc., not bright).
After the feedback gain is adjusted properly, set the mixer gain: After the basic volume of the feedback suppressor is set, turn on the PFL monitor button of the mixer, speak into the microphone, speak louder than normal use, adjust the tuning gain, and adjust the level meter occasionally The position of the yellow light is the appropriate gain position.
Next, set the main output and channel volume of the console. The main output of the console is set at about -5 to -10, and the system is relatively quiet; then start talking, and slowly increase the channel volume. When there is a whistling sound, press Press the feedback start button, and the total output volume is slightly reduced; in this way, the system is adjusted, and the future use will remain unchanged at these positions. Following the above steps, the feedback suppressor can be easily adjusted.
