Report "I have a Vocopro 5800 Professional - 4 mic. I've had it for about 2 years and it's starting to have a few problems. The white microphone, when turned on, will work perfectly fine for the first few seconds and then a "galloping" noise will begin to overpower the speakers. It is a constant low thumping noise that make its entirely impossible to even use the microphone. the yellow microphone will work fine until we turn the purple microphone on. When the purple is on, the yellow will stop working altogether. lastly, the pink one works but it adds a little tremble to the vocals. It makes the voice sound like it is singing through a fan. any help would be greatly appreciated it! thanks!"
