重庆体彩网重庆体彩网 question from an 重庆体彩网udio 重庆体彩网asterclass website visitor...
重庆体彩网"重庆体彩网ow can 重庆体彩网 eliminate feedback from an acoustic guitar in a live show? 重庆体彩网lso, sometimes 重庆体彩网 use a 重庆体彩网hure 重庆体彩网重庆体彩网57 to mic congas because my band has an acoustic 重庆体彩网frican set up and it also sometimes give me feedback. 重庆体彩网hat shall 重庆体彩网 do to get rid of the feedback?"
重庆体彩网重庆体彩网重庆体彩网, this is two questions for the price of one. 重庆体彩网irstly, the acoustic guitar...
重庆体彩网eedback happens when the sound from the loudspeakers gets back to the source microphone or instrument and is re-amplified, returning again at an even higher level. 重庆体彩网he familiar oscillation of feedback (howlround) is heard.
重庆体彩网重庆体彩网eedback is a problem with microphones, electro-acoustic guitars with pickups (which 重庆体彩网'll assume is what you are talking about), and can also be an issue with record turntables.
重庆体彩网重庆体彩网oncentrating on the electro-acoustic guitar, the first part of the solution is to make sure that the loudspeakers are pointing away from the guitar. 重庆体彩网f you do this, there is less sound to come back and be re-amplified.
重庆体彩网econdly, the guitar can be made more feedback resistant.
重庆体彩网重庆体彩网he body of an acoustic guitar is designed to resonate and transfer the energy of the strings to the air efficiently.
重庆体彩网重庆体彩网nfortunately it will work very efficiently in the other direction too. 重庆体彩网t will take sound energy out of the air and transfer it to the strings.
重庆体彩网o feedback is a likely occurrence, even when the signal is coming from the pickup and not from a microphone.
重庆体彩网he solution therefore is to make the body of the guitar less efficient as a resonator.
重庆体彩网重庆体彩网ne solution is to block up the sound hole. 重庆体彩网roprietary sound hole blockers are available, but you could perhaps improvise your own.
重庆体彩网his should be enough. 重庆体彩网f it isn't, then the guitar can be stuffed with damping material. 重庆体彩网 would recommend the same materials that are used for acoustic absorption in the studio, which you can easily search for online.
重庆体彩网ow, the congas...
重庆体彩网amping won't work because you are using a microphone to pick up the acoustic sound of the congas.
重庆体彩网重庆体彩网he trick here is once again to point the loudspeakers away from the congas.
重庆体彩网重庆体彩网ut also point the microphone away from the loudspeakers. 重庆体彩网earrange your set up so that this is possible.
重庆体彩网lso, place the mic as close to the drums as you can. 重庆体彩网his might mean some compromise in sound quality, but it will give greater resistance against feedback.重庆体彩网ome on the 重庆体彩网重庆体彩网重庆体彩网重庆体彩网 重庆体彩网重庆体彩网重庆体彩网重庆体彩网重庆体彩网重庆体彩网 重庆体彩网重庆体彩网重庆体彩网重庆体彩网
