## Questions & Answers

**Q: Should we carry all the time during conference or can we place it on somewhere on table**
A: I give tours with it in my vehicle and I sit the speaker in the area of the passengers and it works great

**Q: no charger included?**
A: Call the sale people. Usually, these kits have a USB connection with them.

**Q: How to I get my iPhone music to play through the amp while simultaneously speaking into the wireless head set mike to call out line dance steps?**
A: I connect my iPhone via bluetooth to the speaker I'm using, and that's where my music comes from. (I use this mic to teach a fitness class, so my microphone plug is connected to a second speaker in the studio.)

**Q: Will i be able to hear my students through this device?**
A: The headset doesn’t cover your ears, so hearing things is all based on how loud your music is
