Which rear speaker connections - SL & SR or SBL & SBR

Just trying to hook up the Denon AVR 1909.

I'm using a 5.1 speaker system but the handbook is really unclear as to which rear outputs to use if not a 7.1.

So do I want the side ones (SL and SR) or the back ones (SBL and SBR)?

SBL and SBR are the extra rear outputs in a 7.1 system

So if you are running 7.1, which are surround and which are the rears? And does this mean that which terminals you plug your rears into is dependant on if you are running 7.1 or 5.1?

SL/SR are either side of the the listening position (or to the side and slightly behind for 5.1), SBL/SBR are behind. SL/SR are the same for 5.1/6.1/7.1, the additional terminals are only used for 6.1/7.1.

Just realised i've been led astray in my view of a 7.1 setup. I'd been led to believe that the additional surround speakers sat in between the rear speakers and the front speakers.

Sorry, wrong end of the stick on my part.

Cheers for clarifying.

No problem - it's easy to see where the confusion lies.

In a 5.1 set up, the rears should really be between 90 degrees (i.e exactly at the side of the listening position) and 120 degrees (still to the side, but further back, 180 degress being exactly behind the listening position). However, most diagrams will show the positions in the rearmost possible position (or even further back in some I've seen).

When 7.1 is depicted, the original rears are pushed forward (to 90 degrees) and the additional speakers inserted behind and between the originals. However, it can easily look as if the original rears have moved closer together and the additional speakers added to the side.
