## Questions & Answers

**Q: What is the difference between bodypack A and Bodypack B?**
A: The difference between A and B is that the 4 frequency points are different. If only one system needs to be used, choosing either A or B has no effect. But if you need 2 systems to use together, you need to choose one A and one B. Because the same frequency points will interfere with each other.

**Q: Can we purchase handheld wireless mics to use with our bodypack b system?**
A: Yes,friend. But you need contact us in our e-mail.

**Q: Will rechargeable batteries fit in the microphones since they are bigger?**
A: Sure Rechargeable batteries are even better than the one time use batteries
Just keep a back up , nearby set of batteries 

but the whole system is super

**Q: I need a system with 1 handheld & 3 headsets. The closest configuration is 2 handheld & 2 headset. Can I purchase extra headset/bodypack?**
A: Additional earphones/bodypacks can be purchased. Please email our customer service.
