The Lexicon CP-1 is an amazing vintage video and audio processor. It boasts a unique "Panorama" sound mode, which allows you to put it into two-channel mode; then with only two speakers (though you can use more than that), you're given the impression that you're running a center channel when you don't actually have one. You can also use this sound processor as a preamplifier, which allows you to add specific tonal qualities to your sound system. Just pair it with a nice power amp and you're all set to listen to music how you want, the way you want!
