Feedback is a high-pitched squealing noise that occurs when a sound system’s output is picked up by its microphone and re-amplified. This can create a positive feedback loop, causing the squealing to become louder and louder until it becomes unbearable. Feedback can be a major problem for performers, as it can ruin a performance and damage equipment.
There are a number of things that can be done to avoid feedback on stage. One is to make sure that the microphone is not pointing directly at the speakers. Another is to use a microphone with a cardioid pickup pattern, which is less likely to pick up sound from the speakers. It is also important to keep the microphone as far away from the speakers as possible. Finally, it is helpful to use a feedback suppressor, which is a device that can help to reduce the amount of feedback that is produced.
By following these tips, performers can help to avoid feedback on stage and ensure that their performances are successful.
1. Microphone placement
One of the most important things to consider when trying to avoid feedback on stage is the placement of the microphone. The microphone should not be pointing directly at the speakers, as this will create a positive feedback loop. A positive feedback loop occurs when the sound from the speakers is picked up by the microphone and then re-amplified by the speakers. This can create a high-pitched squealing noise that can be very unpleasant and can even damage the sound system.
To avoid feedback, it is important to position the microphone so that it is not pointing directly at the speakers. The microphone should be placed at an angle to the speakers, and it should be as far away from the speakers as possible. This will help to reduce the amount of sound that is picked up by the microphone, and it will help to prevent feedback from occurring.
In addition to positioning the microphone correctly, it is also important to use a microphone with a cardioid pickup pattern. A cardioid pickup pattern is a type of microphone pickup pattern that is most sensitive to sound coming from directly in front of the microphone. This will help to reduce the amount of sound that is picked up from the speakers, and it will help to prevent feedback from occurring.
By following these tips, you can help to avoid feedback on stage and ensure that your performance is a success.
2. Microphone type
A cardioid pickup pattern is a type of microphone pickup pattern that is most sensitive to sound coming from directly in front of the microphone. This makes it less likely to pick up sound from the speakers, which can help to prevent feedback from occurring.
- Reduces feedback: By using a microphone with a cardioid pickup pattern, you can help to reduce the amount of sound that is picked up from the speakers. This can help to prevent feedback from occurring, even if the microphone is positioned close to the speakers.
- Improves sound quality: A cardioid pickup pattern also helps to improve the sound quality of your recordings. This is because it reduces the amount of background noise that is picked up by the microphone.
If you are looking for a microphone that can help you to avoid feedback and improve the sound quality of your recordings, then a microphone with a cardioid pickup pattern is a good option.
3. Microphone distance
Keeping the microphone as far away from the speakers as possible is crucial to avoiding feedback on stage. Feedback occurs when the sound from the speakers is picked up by the microphone and then re-amplified by the speakers, creating a positive feedback loop. This can result in a high-pitched squealing noise that can be very unpleasant and can even damage the sound system.
- Reduces the amount of sound picked up by the microphone: The further away the microphone is from the speakers, the less sound it will pick up. This makes it less likely that the sound from the speakers will be re-amplified and cause feedback.
- Gives the sound waves more time to dissipate: When the microphone is further away from the speakers, the sound waves have more time to dissipate before they reach the microphone. This makes it less likely that the sound waves will be reflected back towards the speakers and cause feedback.
- Makes it easier to control the direction of the sound: When the microphone is further away from the speakers, it is easier to control the direction of the sound. This makes it less likely that the sound will be directed towards the speakers and cause feedback.
- Improves the sound quality: Keeping the microphone further away from the speakers can also improve the sound quality. This is because the microphone will be less likely to pick up unwanted noise from the speakers, such as distortion or hiss.
By following this tip, you can help to avoid feedback on stage and ensure that your performance is a success.
4. Feedback suppressor
A feedback suppressor is a device that can help to reduce the amount of feedback that is produced by a sound system. Feedback occurs when the sound from the speakers is picked up by the microphone and then re-amplified by the speakers, creating a positive feedback loop. This can result in a high-pitched squealing noise that can be very unpleasant and can even damage the sound system.
- How feedback suppressors work: Feedback suppressors work by using a variety of techniques to reduce the amount of feedback that is produced. Some feedback suppressors use equalization to reduce the gain of the frequencies that are most likely to cause feedback. Others use digital signal processing to identify and cancel out feedback before it can be amplified by the speakers.
- Benefits of using feedback suppressors: Feedback suppressors can be a valuable tool for performers who want to avoid feedback on stage. Feedback suppressors can help to improve the sound quality of a performance by reducing the amount of unwanted noise and distortion. They can also help to protect the sound system from damage.
- Different types of feedback suppressors: There are a variety of different types of feedback suppressors available on the market. Some feedback suppressors are designed to be used with specific types of microphones, while others can be used with any type of microphone. It is important to choose a feedback suppressor that is compatible with your microphone and sound system.
- How to use feedback suppressors: Feedback suppressors are typically easy to use. Most feedback suppressors simply need to be plugged into the sound system and turned on. Some feedback suppressors have additional features, such as adjustable gain and equalization, that can be used to fine-tune the performance of the feedback suppressor.
If you are experiencing feedback problems, using a feedback suppressor can be a helpful way to reduce the amount of feedback and improve the sound quality of your performance.
