## Questions & Answers

**Q: Is it possible to be a microphone as one of the input sources?**
A: Dear Chanwoong Park,

Thank you so much for inquiring.

The Just  Mixer S do not provide condenser mic.
Because the Loop Mixer do not provide phantom or plug-in power for microphone. Regular mics that can be connected directly to the microphone jacks of PCs will work fine, but condenser mics and other mics requiring additional power source may not work. As below link for reference.
Dynamic Microphone

XLR to 3.5mm

So we suggest that you can use Dynamic Microphone and connect XLR to 3.5mm adapter.
On the other hand, you can use AVL606 Microphone which has provided power.

Besides , we have a microphone mixer of Just Mic 4 and Just Mixer M , Loop Mixer 8 for mics Mixer for reference.

Please let me know if you have further questions or comments.

Thank you again.Have a good day.

**Q: Is this trrs?**
A: All TRS.

**Q: Does the headphone jack cut off the line out when a cable is inserted? If so, how would I rig up an external female plug to be the "mute switch"?**
A: Dear Judas Ghost,

Thanks for contacting us.
Because the Just Mixer S of headphones and the output are on the same line, if you plugging in the headphones does not cut off the output line.
