If you are running a 5.1 speaker set-up then SR and SL are simply your surround speakers. Use those connections on your receiver.
When you add rear surrounds (sometimes called center rear) for a 7.1 set-up, they get connected to the REAR surround out-puts on your receiver.
So.... just hook up your surrounds to the SR & SL connections, tell your receiver that you have 5 speakers in the set-up menu and you'll be good to go.
Hope this helps.
