## Questions & Answers

**Q: Hi there, I was wondering if this amplifier is waterproof? Can it be used in outdoor environments or near water without any issues?**
A: Yes! The ad states -WATERPROOF VOICE AMPLIFIER WIRELESS- The Portable PA System is rugged enough for outdoor-indoor use and rigorously tested to meet IPX6 waterproof standards.
IPX6 means the product can resist high-pressure, heavy sprays of water.
IPX7 means the product can be submerged up to 1 meter in water for 30 minutes.
So as long as you are not submerging it in water it should work fine.

**Q: I was curious about something. When the microphone is in use, does it produce any unwanted noise or feedback?**
A: No, it works well

**Q: I was wondering about the usage time of the amplifiers and microphones. How long can I expect to use them before needing to recharge?**
A: It lasts for a hour of sustained use for me.  Or, three hours of use if turn it off between needs.

**Q: I was wondering if you could explain how to pair microphones and amplifiers together. I'm not quite sure how to go about doing that.**
A: No need for manual pairing, this one has automatic connection, I highly recommend it, it's the only one on the market and it solves a lot of problems.
