Now that we know how the mid-sweep knobs function, let's use them to cut microphone feedback. Click here if you haven't read the previous article ‘The Magic Knobs Called Mid-Sweep'.
Follow the step's below:
- Pick a channel to set up a microphone. For example channel 1
- Set all the eQ knobs to 12 o'clock (dead center).
- Speak into the microphone.
- As you push channel one's fader higher (make the microphone louder), feedback will occur. You may have need to significant volume. WARNING! Sustained feedback can cause damage to your speakers .
- Mark the position of fader where feedback occurs. Then bring the fader down to soften volume and eliminate feedback.
- Turn the frequency knob of your mid-sweep section anti-clockwise to 7 o'clock. Turn the attenuation knob anti-clockwise to the 9 o'clock position.
- Bring up the fader to the marked position. As the feedback occurs turn the frequency knob clockwise until feedback is eliminated.
Steps 6 and 7 may be used when feedback occurs on a known microphone during a service. This is a better solution than suddenly lowering the microphone's volume thus affecting the preaching or performance.
Warning! If you do not know which microphone is causing the feedback, do not try this.
Warning! If you do not know whether the feedback is coming from the house system or the monitor system, do not try this.
