The stereo drive circuit
The preset amplifier has a low impedance and it is designed to drive long cables, which allows people to listen to the music far away without expensive selective cables. It has an impedance of 16Ω at 1KHz, which makes it connects witch the ordinary ring wires, loudspeakers or alarm cables. It needs a pre-amplifier near the distant music source, such as a disc player, and then people go to a wanted distant place to listen to the music. The receiver point No. of the pre-amplifier is sometimes less than one.
