Sansui 11000 whits end

OK so i got this new Sansui and my head is going to blow
i do consider myself pretty tech savvy but this has got me under the stump
i have no idea what Im supposed to have on or off on this thing there area so many combinations i dont even know where to begin
im trying to hook up some Bose 901 and Im not using the Bose contoller which ive been told is just a EQ which i have Im at the point now where i think the Sansui might be bad !!! UGGGH but i doubt it i think Im the one who cant figure it out
i cant even find a users manual on line
i really need some help here its killing me to be honest
and anyone can email me direct if they want at raleroaded@gmail.com
