A stereo line driver for feeding long cables or buffering an audio source.
This pre-amplifier has a low output impedance, and is designed to drive long cables, allowing you to listen to a remote music source without having to buy
expensive screened cables. The very low output impedance of around 16 ohms at 1KHz, makes it possible to use ordinary bell wire,loudspeaker or alarm cable for connection.
The pre-amplifier must be placed near the remote music source, for example a CD player. The cable is then run to a remote location where you want to listen. The output of this
pr-eamp has a gain of slightly less than one, so an external amplifier must be used to drive loudspeakers.
