Need help please with my Supratek ....

Hey guys I am fortunate enough to have just acquired a Supratek Chardonnay, however the previous owner did not supply the manual and knows nothing about it as it was his fathers. Anyhoo if someone would be so kind as to tell me the input/output layout because they are not labeled and I don't want to fry anything. Also I know these are kinda built to speck individually but Mick has to follow some order like output to the far left or far right, all the rca's are in a row 8 across no spaces. I have an email into Mick but nothing yet. Thanks in advance
