Step 3: How to Use This Module--Adjust Audio and Amplification

On the back of the circuit board there is an audio player for adjusting potentiometer of large multiples(see the red arrow)

Adjust clockwise to reduce the sound, frequency amplification and sound smaller; Adjust counter clock-wise, increase the magnification factor, the sound becomes louder.

There is a potentiometer on the front of the circuit board to adjust the tone. (as shown in the picture )

Adjust clockwise to lower the sound Sink, adjust counterclockwise ,
sound becomes shrill. After finished, press the reset button on the left . Only to reset the system and load the latest tone, it will become effective.

Notice : 1、Due to the limited driving capacity of the sound changer itself, it cannot directly push the speaker to make sound. Please use a 3.5mm jack to connect the audio output of the sound changer to the headset or external amplifier sound.

2、When connecting the audio system, please notice that audio system should be far away from the microphone, because of the audio output will also be transmitted into the microphone, which will vibrate, especially if the audio amplification is maximized. At this point, it is necessary to adjust the potentiometer in combination with audio amplification to select the appropriate audio amplification multiple;This problem does not occur when testing with headphones(because the output sound from the headset is not transmitted to the microphone).

3、The volume adjustment mainly depends on the external amplifier sound volume adjustment,audio amplification multiple adjustment potentiometer can only adjust the volume to a certain extent.
