I picked up a 10-inch record at a flea market called "Motorola Presents 3-Channel Stereophonic High Fidelity." I believe that it's from about 1959-60. The blurb on the back talks about the "Golden Audio Separator" which splits the stereo signal into three channels - two for highs and mids and one for lows. Was this system merely an active crossover? Is the record that I bought any different from the standard stereo records of that time? The blurb on the back wants me to believe that it is. J. D.
