unfortunately, for this year's models in the US, the multichannel analog inputs have been dropped. not even the top US model SC-79 has them. the new HDBaseT ethernet-HDMI connection is where the 7.1 inputs used to be. for the last few years, only the top model had them, none of the lower models.
if you are in Europe, you are in luck because Pioneer Europe/UK decided to keep the 7.1 analogs this year in their top model and wait out putting in HDBaseT. the European equivalent to the SC-79 is the SC-LX87 and it has them.
if you are in the US and truly need them, look to last year's SC-68, or older like the SC-57 or SC-37. be aware that even the models that had them no longer have analog-to-digital converters on the multichannel analogs so you can't add digital processing like PLIIx or even MCACC with them. pure direct mode only. the last model to have ADC's was the SC-27, about 4 model years ago. no receiver company puts ADC's on 7.1 analogs and mc analogs are gradually going away. Onkyo dropped them entirely last year. Denon, Marantz & Yamaha still have them. but if one reads T-leaves, don't be surprised if more drop them in 2014
btw- there are ADC's on 2 ch analog inputs so you can do all the digital processing you want on them
