## Questions & Answers

**Q: Can I run two different signals into the left and right of one channel then connect two body packs to that channel and have two separate feeds?**
A: Hi, thanks for reaching out. Unfortunately no. The PTM-33 is a mono system, which means both left and right input will be heard on left and right ears at the same time. You would need a stereo system such as our PTM-10 to do what you described. Thanks.

**Q: Can this be used with the two receiver system?**
A: Hi, thanks for reaching out. Are you talking about the PTU-71 wireless mic system? Yes, all of our microphone systems are compatible with our microphone systems.

**Q: Do you sell body packs to add on and what is the price**
A: Hi, thanks for reaching out. The bodypack of the PTM-11/22 is compatibel with the PTM-33 system. You can purchase it directly on Amazon. Thanks.

**Q: My mixer only has xlr balanced outputs. Can i adapt to 1/4 in and it work ok ?**
A: Hi, thanks for reaching out. Yes, you can purchase a 1/4” to  XLR cable to connect the IEM to your mixer. Here is an example: https://www.amazon.com/DREMAKE-Microphone-Splitter-Adapter-Unbalanced/dp/B0B7BKGJQN/ref=sr_1_5?keywords=1%2B4%2Bxlr%2Badapter&qid=1685179978&sr=8-5&th=1
