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.

I recently purchased a M-K 038 System. The Lavaliers seem to work fine but the head mics reverberate severly. What do you suggest?

I am looking for replacement bodypack and headset microphones for M-K038. Do you sell them? If not, do you know where can I get them?
Hi @Audrey what kind of speaker you use? If the device has more than 20W output power. The sound should be quite decent for a small room even if you use a lapel mic. And if it’s a PA, then the mic should work fine for even an outdoor gathering.
Before we get to know more about the speaker, I’m sorry that we’re going to say are something you may have heard numerous times. But they would actually make some difference. The lapel mic has a small capsule and it was not possible to point directly to your mouth. Thus audio signal comes in weaker. It’s crucial important to get it closer and closer to the sound source. Next, try using the AUX output jack and crank up the mic volume on receiver. At last, if your speaker has MIC jack, please plug into it instead of the the line in jack.
The lapels mics do not pick up much sound unless they are directly in front of the speakers mouth. We have adjusted it numerous times. What can we do to fix this issue?
