Cordless Microphone - Popping Noise

DJ Auntie M said:

I have not had the Active speaker system all that long and have only used it a few times. But the last three out of four times I have had the popping noise out of the mics. I think I will start with new more expensive XLR wires for the speakers and go from there. I was just thinking that a separate system for the mics might diffuse the problem for now if anything! Or maybe a new wireless mic system but like said I have zero problems with the mic system along with my passive system for Karaoke.

Of the few times, was it in a specific facility or various facilities? Have you tested this one multiple circuits at said facility (ies)? Again, being that you're not experiencing this at home - kinda rules out the active speakers or microphone as causing the problem. Could be interference. Could it be a bad ground on the electrical outlet(s)? Faulty wiring? IMO, whatever it is, is external to 'the system' otherwise you'd be experiencing this at home too and because of that - whatever system you get, L1 or otherwise, may experience the very same problem / symptoms.

Might seem like a stupid question - but are you running the VocoPro into a mic line?

I also remember at one time, the VocoPro's were recalled - just can't remember for what. Why you would also see this only with active speakers (at a facility) is kind of odd too. Doesn't VocoPro use UHF? If you use a different wireless mic, do you experience the same issues or is it only VocoPro? Could very well be frequency issues - but I would think you would hear that on both the active and passive drivers. Still wondering if its a ground issue being that you hear it on the actives.

Not sure what speakers you are using, but on VocoPro's own document (regarding the PV802 speakers):

There is a loud popping sound coming out of the speakers
• There may be a bad cable somewhere in the system
• Make sure there are no damaged microphones

IR not a good solution

I wrote the other review about not working with direct line of sight. We have since then move the receiver on top of the speakers and aim it at the singers (karaoke) which has been a workaround for drop outs. However a new issue arose, we started playing in a place with about 20 TV's and guess what? Big time crackling popping noise when you bring the mic down low at waist level and increasingly getting worse so assuming using the same FCC infrared frequencies as TV's. Tried moving the remote sensor...
around with no luck. I called their tech support line and requested a swap out with a frequency based solution, no go. I am very disappointing in this product

I bought this system because of the lack of possible need for FCC licensing. I have had the system for 6 months, and I use it once per week for one hour every month. It has problems with reception, even in a small room. Lots of drop-outs. Already one microphone has quit working. It started with lots of fuzz in the sound and then the receiver just quit recognizing the mic. I have not been pleased with this product.


No Go for Pro Applications

Pros: Good microphone sound quality, wide frequency range of pickup in the low and high frequency bandwidth. Seems to keep a good charge of about 5 hours. No clicks or pops when turning microphone on or off. Green light is on when microphone is on. Cons: Terrible reception, if anything (including screens) comes between the mic and the rack receiver it cuts out, even if it's 3 feet away from the receiver if there is not a line sight it will cut out, I would not recomend this for any professional applications...
unless the mic is in a stationary position. Range is about 30 feet with direct line of site. Useless as a rack design receiver as normally the PA rack will be out of line of site to the microphone. Best solution would be to hang receiver from the ceiling, however that is simply not logical. The charge contacts are thin and flimsy and appear to be an alloy not copper. (maybe to avoid corrosion?
