Looking for a service manual for a Sony SS-CR64

[GateCrasher]

If anyone has information or has a copy of a schematic or service manual for a Sony SS-CR64 home stereo speaker system I would greatly appreciate it.

Thanks

I need the instructions for the Surround Sound and Dolby features on this unit. The center speaker only comes on by itself, or all the other speakers (front, rear and sub-woofer). The Surround Sound feature has simulated, hall and dolby as selections. Then there is a different set of buttons for 3ch, etc. How do I find out what the correct combination is to get all the speakers on at once, including the center speaker, with either the Surround Sound feature on, or at least all the speakers on?
thanks.

BTW: This IS the Dolby Pro-Logic system.
