pre-amp or power amp with integrated?

I have a rotel ra 1062 and am wondering if its possible to add a power and or pre-amp to it-thanks.
Does it have left and right jumpers labeled 'Pre Out - Main In' or something to that effect? If it does then yes you can.

It looks like you can at least add a power amp.
You can use the pre-outs on the back of the RA 1062 to connect it to a power amp.
