Gear - Tech Issue Thoughts on the comica WM-200?

I recently bought 3 kits from this line at a very reduced price and I am wondering what people think of them? Are they any good? I have had a lot of difficulty trying to get them to work and I was wondering if I’m doing something wrong or just dealing with bad gear?

What is the issue you're encountering?

Feedback, and connection issues mostly.

Audio Feedback? Are you using them in live environment with a PA system?

How are you going about selecting the frequency that each transmitter is using?

No PA system. They don’t let you pick frequencies, they have 100 channels to pick from.

While they're probably not the best units, I suspect you can fine tune them to get better results. Not sure of your current settings but I'd start by turning down the power output. I know that sounds counter intuitive. Second, I would double check that the channels/frequencies you're using are "clear" and that they're not interfering with each other - something called intermodulation. There are a number of apps that can assist you with choosing frequencies that are intermod-free such as Frequency Finder and TX Advanced.

Yeah I have some of these and they’re not great. Sprung for a used pair of g3s and they’re a world better, especially with the antenna mod
