Thus,it needs one point connetion method.The so-called one point connetion means the reference potentials of every part are the same.The picture a,b is the one point connetion method.As the picture (a),the ground of input end and amplifier is connected to the ground of power supply by one line.Therefore,all return current is circulated between the input signal ground and the amplifier.If among the benchmark ground there is a wiring resistor RC,it will generate noise and hum.
