A stereophonic spatial expansion circuit with tonal compensation and active matrixing |
摘要 |
In a stereophonic expansion circuit, the (L+R) sum signal is spectrally modified by increasing the bass and treble frequencies relative to the midrange so as to compensate for a midrange frequency boost in the (L-R) difference signal. The stereophonic expansion effect and manipulation of the signal parameters are produced by active matrixing amplifiers. |
