GTDaudio 4x800 Channels UHF Diversity Wireless Cordless Microphone System

This is the second GTC product I've used and having four mics comes in handy at times. They are not that expensive but do the job and actually sound quite good. WE have used this unit dozens of times and it does well for what it is. Easy set up and good build.

Functionality: I'm a professional audio engineer and have used many of these and its the best deal you can get functionality for this price range. Sound clarity and lack of noise or dropouts, signal strength and distance it works as well or better than others costing twice or even 3 or 4 times as much. Except for 1 function which its claims it has, but in truth does not exist, not in any way as described in the instructions. It seems the Handheld mic has been redisighned perhaps, and this photo described function on page 5 of the manual, dors not exist as described. Page 5 shows a photo (see my photo and video) a little switch (as you unscrew the hand held mic), to adjust mic gain sensitivity. Its non existent as I demonstrate in the photo and video. Manufacturer website has no phone number so no way to reach them for tech support except by email. But the online email tech support which i filled out online has not been answered in the past week. Overall I gave ut 5 stars anyway because thos function is not needed by most people most of the time. For all practical purposes it Plug and Play. Reciever is in a metal case, but although mic works perfectly but the feel in your hand, feels cheap and overky lightwaight, because other than the grill, its all plastic For a set for $319 we could expect the mic to be made out of Metal instead of Plastic. One of the biggest advantages of this mic, is its TRUE DUAL DIVERSITY (4 Antenna's) which helps increase its range even in adverse environments without any loss if signal and no dead spots nor any dropouts. I also appreciate very much the 4 mic Reciever has 4 Seperate very detailed and very informative, forcseperate LCD displays for each seperate mic to tell you every detail of the status of each mic. At compettitors models, many users report noise. But with this model from this manufacturer i have never experienced any noise such as is comonly reported by amazon user feedback from competitors systens.

I bought these for my own karaoke system to replace wired mics. They were easy to set up and connected easily to my Yamaha MG10XUF mixer. First, the pros. The mics sound very good and are comparable in sound quality to my Shure wired microphones. I can walk right up next to my speakers without producing any howling or screeching. Even though they're made of plastic, they feel quite sturdy. Now the cons, and they are few. On the receiver, the volume buttons for the mics are recessed and can only be adjusted with a small screw driver. On the microphone, there are two buttons. One button serves as Power and Mute. The other, marked Select, changes the Group and Channel frequencies. Many times, my guests have pushed the Select button by mistake and end up changing either the channel or group, thus un-syncing the microphone from the receiver. You can lock in the frequency by simultaneously pushing both buttons, but then you can neither mute or turn off the mic, unless you unlock the frequency again. Got to have a better way of making sure users don't accidentally disable the mics. Battery life is mediocre, as the mics drain my Eneloops very quickly. I'll update the review as the mics get more use, but for now, they do the job well, with a few negative points.

Very satisfied

For the price they are awesome. These are great if u press both buttons they lock so Noone can accidentally turn them off. They work great. Only thing if u singing sings too loud then you might get signal drop

For the price this sounds great. It's competing with my sennheiser. I had artists prefer this more. Remember to fully set the gain within the unit as well as under the head of the microphone and the gain on the channel a long with compression and it will sound outstanding. I have 1 unit, I'm buying 2-3 more. Great product. The item could use more weight. Fyi: my-setup, 120 ft from unit-line of sight, and 6 other wireless sennheiser microphone, 1 sennheiser IEM, in operation and wifi router as well. Didn't have any issues at all. Con: I can not use my rechargeable batteries in this unit they get stuck. Will be uploading a unboxing video soon when I order the other microphones.

I'm a KJ host and find these mics to be very good. They come in really hot and my singers tend to like that. I have a really good sound board so this allows me to mold the sound to my liking without having to crank the gain. As a singer I like to do challenging songs on the high end and these mics make it a breeze to flow in and out of falsetto with hardly a notice.

Running 10 receivers (40 microphones) simultaneously. Only used this system 4 times so far, but it seems to be working perfectly. The user manual is a disaster, though. Insufficient instructions, and what little is there is often wrong. I am still unable to adjust the gain of the microphones. There are only two settings (-10 dB and 0 dB). It would be nice if there was a higher gain available.
