Using it want to connect a small speaker to the XBOX 360. On the advice from the Internet connected in the gap of the module and the column variable resistors, but the volume only responds to a couple of percent of turnover, then the sound disappears. It is not easy to accurately adjust. With amplifiers don't know, so I don't know where and what resistor to connect(and google articles contradict each other)
