## Questions & Answers

**Q: What are the exact 20 frequencies on these units please.  what is the mw output of the transmitters please.?**
A: Frequency is 565 to 584
Power 10db/10MV

**Q: I have a sony srs xb20 speaker can i use your system if i use a 1/4 to 3/8 adapter to plug into the Sony unit? if not why not?**
A: No, you can't. Because this receiver output is about the same level as a wired mic. It must be plugged into a 1/4'' speaker input designed for a mic connection. If your speaker has only 3.5mm line inputs which require a higher level signal than a mic provides, the mic will be not suitable to be used with it, even you add an adapter. The sound will be soft and hard to be heard.

**Q: Can I plug the receiver into my iPhone, audio mixer, or Mac to record the audio?**
A: Sorry, it works with only audio mixer that has 1/4" mic jack. If you need a mic to use with Mac, we have the K031 (Asin: B074C125TN) USB wireless lav mic. But neither of them will work with iPhone.

**Q: can it be used for singing**
A: It will be more suitable for speaking than singing. 
We would recommend the handheld mic K025(ASIN:B0795PNCBG) or K035(ASIN:B01MT6AAIC) for singing. All these mics need to work with speakers/amps that has 1/4'' mic input.
