What is feedback? Feedback can happen if you have a sound system with a microphone (or an instrument), and powered speakers. It occurs when the speakers to get the sound through the microphone (or a pick-up of the instrument), reamplified collected and sent through the speakers again and again in a cycle screaming or yelling.
Why could feedback? Technically feedback happens when the gain is too high for the release of a microphone. Many factors can create a feedback set problembut the arrangement of the components of the system is an important factor in sustained feedback. Proper placement of speakers in relation to a microphone or instrument, at the end of the feedback problems.
Here are some common causes of Feedback:
Live microphones go in the direction of the speakers noted an increase
The microphone and speakers are amplified close
The person with the microphone bracket before speakers
The directional nature of the microphone -directional microphones are less likely to cause a feedback omni-directional microphones
Show Microphones later
The response of acoustically reflective surfaces causes the room - too many echoes corresponds more feedback
The presence of multiple microphones and powered speakers - the more devices you get the more likely you have accidentally created feedback
The singer holds the microphone too far away, so that the karaoke DJ to turn the volume ofMicrophone, which increases the possibility of feedback
What is the best option for feedback? proper disposal of equipment will be cut 95% of the responses. Unfortunately you can not always control the system is perfect or 100% of 'acoustic environment. Sometimes the option for the placement of the speakers, particularly non-negotiable. Therefore, the following suggestions are solutions ideal scenario, but it is not always possible.
Place the speakers in front of the microphones (and tools)or
Set the speakers away from the person singing - 180 degrees is ideal, but not always realistic
Do not show live together Microphones
Holding microphone closer to your mouth, so that the volume can be lowered
Do not cup the microphone with your hands
Turn microphones or other material that is not used
Use unidirectional microphones - a set of omnidirectional wireless is cool, but creates more questions Feedback
Soundproofing of the rooms - the echo reductionreduce feedback through the microphone
If an equalizer to lower the frequency of specific feedback is the cause of the problem - 400K is a common trouble
