What's the best way to remove the batteries? The first (bottom) battery is easy to remove but the second (top) battery is a bit of a challenge.

Hi, thanks for asking! Please refer to the video. After removing the first battery, the second battery can be easily removed. If the battery is still difficult to remove, please email us at support@phenyxpro.com. Thank you.

We are having issues with mics 5 and 7 they keep popping. How can we fix this issue?

First try fresh batteries. Also try operating each individually to make sure the signal from another mic is not the same. Lastly check for digital interference such as cell phones or older neon lights. If the problem still persists, the bikes are shot.

Is the ptu4000a unit powered by batteries only or ac power? if ac, can it be connected to 200/220v power source.

Hi thanks for asking! The PTU-4000A unit powered ac power. Our power adapter works for 110v - 240v and you can use for it. Thank you!

CAn i place the receiver in a separate room, or does it have to be line of site?

No it doesn’t have to be in the same room but check how many feet it can be away from the microphones
