No. The only thing that is powered is the sub-woofer. You should be able to hook each of the smaller speakers into the Right & left channel, center, and right and left surround. The Sub-woofer is powered, but that's all. Use the set-up menu once everything is plugged in to adjust your speakers and you should be all set.
The subwoofer requires an outlet because it is powered and also an spl cable from receiver to sub (which is provided). The other speakers are powered by your receiver via the stereo cable (which is also provided).
Wire for the speakers are provided with the speakers. You need to cut to length. All the speakers then hookup to the receiver. The receiver should have a clip or knob area that you snap or wrap the other end of the wire to from each speaker. There are at least 6 clips or knobs depending on the receiver you have. Mine has knobs. I cut the wire to length for distance of each speaker and the front speakers, of course, were shorter as is the sub-woofer. I only know I have a receiver to hook them up to. I received the receiver as a gift and purchased these new black speakers to go with my new receiver. Hope this helps.
