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

  1. Turn off the power to receiver as well as transmitters B & C before you get started. 
  2. 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.   
  3. The same goes for transmitter C. But what appears on transmitter is the flashing 584.000 channel.   
  4. 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.    
  5. Click the top buttons of both transmitter B & C, resulting in pairing successfully.

    Hi John See. We designed K038 mainly for live event with speaker at the first place,but you can fulfill your need by connecting K038 receiver through R+L Out jack to your computer microphone input. Meanwhile, you still need to provide a wall outlet power for the receiver.
    By the way, we should remind our clients that K038 need to connect with the computer microphone input, not the headphone jack. Although you can use on computer successfully, the result is not good enough, the best way is to use with an audio interface.

    Hi @Sam, first of all, please check if the option of “automatically adjust the volume” was ticked under audio of Zoom setting. In your case it sounds very likely that Zoom does the volume adjustment for you without notification.

    If it still doesn’t help, please refer to the method of “Sharing Screen and Audio” and “Sharing iOS Device’s Screen and Audio on Computer via AirPlay” from the article below. And see if any one of the method fix the problem.

    We are trying to use this over Zoom for a dance class. We are ‘sharing’ the computer audio with attendees but the attendees cannot hear the mic over the music. We have mic ‘turned up’ as high as it will go. Works fine when there is no music playing. Any tips or things we could try?

    Thanks

    Hi Richardson Pierre.
    Did such issue happen when you used the microphone for the first time of just recently?
    How about changing frequency and reset the whole system?
    The reset tutorial video is below, from 344 to 4:54.

    Three notice here during the reset.
    1. All units must be off at the beginning.
    2. 605 and 584 frequency will appear and flash.
    3. The receiver will blink green for three times when being turned on.
