ABSTRACT:
A passive multi channel surround sound simulation device has a pair of input jacks for receiving a two channel stereophonic signal having a speaker level. An electronic circuit produces from the two channel signal left and right primary speaker level outputs, left and right secondary speaker level outputs, a mono center line level output, left and right secondary line level outputs, and a surround ground separate from an input ground. First, second and third voltage dividers reduce the stereophonic signal speaker level to a line level of about 10% of that which appears at the left and right primary speaker level outputs, for directing to the mono line level output, and the left and right secondary line level outputs respectively. The left and right primary speaker level outputs are connected to left and right front speakers respectively. The left and right secondary speaker level outputs are connected to left and right rear speakers respectively. The mono center line level output is connected to a center speaker through an amplifier. The left and right secondary line level outputs allow connection to left and right rear speakers through further amplification.
