Perhaps a little Audio 101 is in order.
An integrated amp is basically two components in one box: A pre-amp, and an amplifier.
The pre-amp section is where all the component inputs are (CD, Tuner, etc.). The volume control, tone controls, balance controls, etc. are also part of the pre-amp. Everything the pre-amp does – volume, tone controls, selected input – shows up at the Pre-amp Output jacks.
If you decide one day that you want more power, you could get a big ol’ high-powered amplifier and hook it up the integrated amp’s Pre-amp Output jacks. Naturally, you have to connect your existing speakers to the new amp. At this point, the amplifier section in the integrated amp is vacated and only its pre-amp section operates.
Alternately, you’ve moved on from the old integrated amp and it was moved to the closet to make way for your “latest and greatest” stereo or home theater receiver. But one day the main L/R amplifier channels go dead in the “latest and greatest.”
Well, you can drag the old integrated amp out of the closet and connect the “latest and greatest” L/R pre-amp outputs to the integrated amp’s Power Amp inputs. Move the existing speaker connections to the integrated, and you have a working system again.
Using the Power Amp inputs, the signal goes directly to the amplifier section and the entire pre-amp section – input selection, volume control, etc. – is bypassed.
Thus, an integrated amp can be used as intended, or as a stand-alone pre-amp, or as a stand-alone amplifier.
