We recently posted series of video reviews for GTDaudio G-788 wireless microphone system. This article will summarize our YouTube reviews and add some more information about this wireless microphone system. GTDaudio review for G-788 wireless microphone system will show few tricks how to tune it up and tweak few things to make it easy to work with GTDaudio G-788 wireless microphone system.
Overall, the GTDaudio G-788 system is a good combination of price and value. I cannot think of any other wireless microphone system with competitive sound quality in this price range . The microphone heads are pretty decent and deliver quality sound if it’s on axis. It does have some issues with off axis frequency response.
Our videos on YouTube will explain, show and compare different features of GTDaudio G-788 wireless microphone system. However there are few things that I would like to highlight and provide a little bit more information.
Changing input gain on GTDaudio G-788 wireless microphone system.
Unfortunately, GTDaudio did not provide any interface option that can change the input gain of the microphone. In many cases this may not be an issue, but if you happened to deal with loud sound sources (singers, speakers etc), then you may need to decrease the input gain so it will not distort the sound.
In order to change the input gain of the microphone, we had to disassemble the handheld and do some tweaking on the socket board. Our video on YouTube shows the entire process, so feel free to check it out (http://www.youtube.com/watch?v=QA5Vvqne0pc)
“Fixing” mute button for accidental offs on GTDaudio G-788
The results of modifications and alterations made to the GTD Audio Wireless Microphone presented in this video, images, and concurrent article may not guarantee desired performance of the equipment due to changes in the original design. The authors of this publications are not liable for any damage of the equipment, loss of warranty, or any other subsequent losses caused by presented modifications.
There aren’t any real fixes for this issue. I believe designers should have thought about it and program some delay on mute button instead of activating it right away. Recently we came with some workaround. We didn’t want to have tape around the handheld since it would simply look ugly, so we found another fix. See step-by-step instructions below. You may do it at your own risk, and we are not taking any responsibility for possible mishaps during or after the process.
1. Unscrew the head from the handheld’s body. Make sure you not separating the grill. Refer to figure 1.
2. There will be a snap ring that needs to be removed. In the picture on figure a green arrow shows where the ring should have been but in this particular picture there isn’t any. We didn’t put them back so during our gigs we can easily disassemble mike to fix the gain (refer to our video on YouTube -http://www.youtube.com/watch?v=QA5Vvqne0pc ). So far no issues, so…
3. There are two small screws behind the battery compartment. Those screws needs to be removed. Refer to figure 3.
4.Once screws are removed, carefully remove the battery cartridge. Refer to figure 4.
5. Now it is little tricky. In order to remove buttons we need to locate a small pin inside the microphone’s body. Refer to figure 5 to locate the pin and push it out. The faceplate should come out.
6. From here is easy. The front should come out easily. Refer to figure 6.
7. The fix is to cut the rubber’s pins that serve as button extensions reaching the actual switch on the socket board. On the picture figure we’ve already cut out the bases. We left almost nothing in order to make sure that these buttons will not activate the switch below with a simple push of the finger. Be careful, since after this “fix” it will be really hard to turn the microphone on with the finger, so you might want to use some kind of pin to turn the microphone on. However, since batteries last long, we just turn them on before the gig and leave like that until the end.
Not the best fix, but sine GTDadio is not a big fan of answering emails, we didn’t have better option.
Overall, this is a good system, especially for the money.
