Sansui SAX-200 Owners Manual Needed Please

Hi Would anyone have an owners manual or
service manual for a sansui SAX - 200 after not
using this reciever for a while I'm unsure
of speaker inputs. Its a little different
from the normal. It has C the 8 then 16 then 32
after getting eletrocuted a beauty 2
Hooked it up sounded terrible then while changing
got zapped. Hooked up a different way
this sounded worse. It also days channel
1 channel 2, I take it as meaning
Channel 1 is left channel 2 right speaker
What I dont understand what does C stand for?
Thanks for your help.
Have a happy day :)
