## Questions & Answers

**Q: How can i huy just the microphones?**
A: You can buy them from GTD Audio. Go to gtdaudio.net and search for 787

**Q: What kind of rechargeable batteries can you use in this unit, they can be used because I try Duracell but they are a little fat and someone broke one.**
A: ** DO NOT DO NOT **
 Use rechargeable batteries in microphones (or any device) that uses standard batteries!!
Standard batteries are 1.5volts. Rechargeable are 1.2 volts.
So if you microphone uses two batteries, it is working with 3 volts.
However, if you are using rechargeable batteries, you are only giving it 2.4 volts which means it may have reduced range and cause other problems, as 2.4 volts is like weak regular batteries.
When someone like Shure provides a rechargeable battery pack option, the pack is actually containing THREE batteries in the pack - even though it fits into a two battery compartment thereby providing 3.6 volts for a 3 volt device.

Again... you will have many problems if you try to use rechargeable batteries in a device like this!!

**Q: Where can I get a manual / pdf?**
A: On the GTD website

**Q: Does this system have echo cancellation built in? (to avoid ringing / resonance)?**
A: It does not and these mics are fairly susceptible to feedback, however you can usually eq the rings out just fine or use the gain control on the receiver to decrease the sensitivity.

### ⭐⭐⭐⭐ Good for the price
*by L***E on May 27, 2020*

I bought a couple of GTD wireless mics several years ago, and they've been solid workhorses, so when I needed more mics I decided to try them again. Setup was easy - actually easier than the manual indicates. The units were all preset to frequencies out of the box, so there was no need to follow the instructions to set them up. I just put in batteries, turned everything on, and everything worked. The only problem I've seen so far is that the mics tend to distort at really high volume. I didn't have this problem on my first set from several years ago, so I'm assuming it has something to do with the gain setting. I looked at the instructions which say that the gain can be set for each mic by removing the capsule (see image). I followed those instructions but couldn't figure out how to adjust the gain. I contacted the seller, who informed me that the gain can't be set on individual mics, in direct contradiction to the instructions. I'm going to try to set the gain on the receiver and see how that goes. Overall, though, these are very solid mics for the price.
