There is acoustic feedback

  • Reduce the volume.

  • Move the microphone away from the speaker or change the direction of the microphone.

Note

  • Bringing the microphone close to the speaker may cause acoustic feedback. When this happens, depending on the sound volume of the speaker, the speaker may turn off due to the product protection feature. In that case, disconnect the AC power cord (mains lead), wait for a while, plug in the AC power cord (mains lead), and then turn on the speaker again.
