Sound output debug


Check two connection points

Most cases of no-sound output are caused by these two connection points

Connection point 1

Make sure the 6.35mm pin is fully pushed into the jack

Connection point 2

Make sure the 2.5mm pin is NOT fully pushed into the jack, you should be able to see the metal pin. You can connect to amp/speaker to debug the best position of the small pin.


Check your speaker / amp

Make sure your amp/speaker is ON, turn gain knob and volume knob to appropriate level

In case there is no 6.35mm audio jack, use audio adaptor for 3.5mm audio input, note that you may need an amplifier for mini speaker.
