Troubleshooting of professional sound interference:

1. tuning sound image: sound image knob we often regard it as a dispensable thing, but when we use the total output left or right output volume, we should pay attention to the sound image. If the total output right output signal but the tone table channel sound image is hit to the left, it will cause a silent failure, which needs to be noted.

2. tone listening and mute switch: Generally, tone listening and mute switch are close together, which must be seen clearly. If the mute switch is not pressed correctly when pressing the listening switch, it will also cause silent failure. 

3. Failure of the equipment itself: if it is a real failure of the equipment itself, it is considered a "hard fault". 

4. Disturbing faults

 Tuner interference source search: most of the tone table will have a 48 volt illusion of power supply, it can be used to promote a variety of capacitor microphone, but because it is from the microphone line transmission current, so often check the microphone line, ensure smooth line, otherwise the line contact bad will be a big current impact sound.
