If your thomann Microphone system produces no sound, try the following: * Verify the power supply to both the transmitter and receiver. * Ensure that the transmitter and receiver are operating within the same frequency range (check the devices for their frequency range). * Confirm that the transmitter and receiver are set to the same channel. * Check the connection between the receiver and any connected audio devices like amplifiers or mixers. Ensure the audio device is on and that the signal level at the receiver's output matches the audio device's input requirements. * Test the audio transmission by moving the transmitter closer to the receiver. * Ensure there are no metal objects near the transmitter or receiver that could be obstructing the transmission.
