Resistance network for generation of stereo sound effect, has front and surround sound loudspeaker joined by additional plus-minus line

摘要

A resistance network device joins the front and surround-sound speaker passively to a stereo device and consists only of resistances that join the front and surround sound speaker through an additional plus-minus line that is available for each loudspeaker via a separate volume matching resistance network and for the sub woofer for each channel, a resistance connection field is available for volume matching.
