Q: How to reset the K038 dual wireless mics system?
A: You can find step-by-step tutorial on K038 problem-solving playlist: http://bit.ly/k038problemsolving
- Turn off the power to receiver as well as transmitters B & C before you get started.
- Power on transmitter B and reset it by clicking the top button for 10 times. A flashing 605.000 channel number shows up if you reset transmitter B proper.
- The same goes for transmitter C. But what appears on transmitter is the flashing 584.000 channel.
- When they are still flashing, switch on receiver. Pay a bit attention here if its RF B & C lights will blink for 3 times before the last step.
- Click the top buttons of both transmitter B & C, resulting in pairing successfully.

Hi @Dean is it a K038 transmitter? If yes, the channel number should be display on the screen. Or it’s a K025, the handheld mic itself should also has a screen to show the CH1 figure.
I have a uhf wireless microphone that will not power up. I would like to buy a replacement but cannot know what the channel number. How do I find the channel number. I have the other microphone..
Hi @Michael Boileau it would not work through the included 3.5mm cable. If you need microphone input to iPad via the lightning adapter, the cable should has the TRRS plug (three black loops on the jack). And if you use with the right cable, for iPad or iPad OS system, the input will be changed to the K038 automatically.
But since you have contacted our support email, our after-sales staff should take care of your case. You can wait for their more detailed email response.
With the lightning adapter on my I-pad, my videos don’t have any sound.
When I go to settings the device isn’t even showing up.
Help!
Hi @Wayne Young we’re not quite sure what kind of reverberate did you mean, was it echo? The lapel mic pick up less of the sound, therefore, it might not be easy to tell if the echo effect is turned on. But when using headset, the sound is louder, it’s more likely to hear the reverb sound. So could you take a look if the echo control on receiver and other kinds of sound effect on your speaker mixer or receiver were turned off?
