The LINE kit is two buffer circuits with transformer-isolated outputs. These output buffers can be fed from a common signal source or from independent signal sources. Using the LINE buffer after a preamp or EQ output will help retain the tones created while driving long cables to external amplifiers or mixing consoles.
