    Do the inputs of an audio receiver plug into the outputs of other hardware devices? (DVD player, Xbox, etc.) If so why do some receivers also have outputs as well? Sorry, very new to home theater. Thank you

    There is no such thing as a stupid question, Alma. [​IMG]
    The video outputs are for the purpose of connecting your receiver to your TV/monitor. This way, you can connect several video sources (DVD, LD, cable, dish, VCR, etc...) to different video inputs on your receiver and use the receiver as a video switcher.
    The audio outputs exist for the purpose of connecting your receiver to an external amplifier to achieve better sound quality.
    By the way, welcome to The Forum! Many of the answers you seek will be here .

    Alma,

    The inputs on a receiver do connect to the outputs on source devices.

    Outputs can connect to recording devices such as audio cassette recorders, vcrs, or CD recorders so that one can record one of the input sources using the receiver as a switching device.

    Many receivers also have output jacks for the 5.1, 6.1, or 7.1 audio channels so they can be used with external amplifiers. In this one would connect the audio output jacks to an external amplifier and in turn connect the speakers to that amplifier rather than directly to the reciever. This is useful if one has power-hungry speakers that the reciever isn't capable of powering adequately. The receiver can do all the processing and decoding of the signal and the separate amplifiers can do the actual powering of the speakers. In this scenario the receiver is being used as a pre/pro (pre-amplifier/processor).

    In the world of high-end equipment there are dedicated pre/pros. These are boxes that do nothing but process signals and switch sources and have no built-in amplifiers as a receiver does.

    There are no stupid questions in this hobby, by the way. The ins and outs of Home Theater are not learned overnight and one of the great things about forums like this is that there are plenty of folks around who've already learned this stuff over years of asking the same questions and are willing to share their knowledge and enthusiasm.

    Welcome!!!!

    Thank you Clinton! Want to buy a home theatre system (nothing fancy) just need to find one with 4 inputs for all the other components.

    EDIT: sorry, seems my answer is a bit redundant, did not see the other responses.
    -----------------

    You might find that this question and other basic ones you might have are answered in the "Home Theater Basics" section of this site.

    But, to your question, let's pretend on the back of your receiver you have a spot that is labeled DVD IN... you would take an output from the DVD player labeled as OUT (be it the red and white rca, the optical cable, or the coaxial cable-- optical or coaxial is required for digital sound, but just pick one type of connection not all three) and plug it into the DVD IN on your receiver. You would then need to select on the front of your receiver which input you are using. In this case DVD player. Different receivers handle the selection differently, but your user manual that came with the receiver should provide more than ample explanation.

    As to why some receivers have outputs... on mine I have various devices going into my receiver(DVD player, gamecube, etc) and so I use the receiver as a central hub where everything goes into, and then I go from the receiver to the television. A lot of times televisions won't have enough inputs on them so you can use your receiver to share some of the responsibility. In which case you would need to use the proper outs on your receiver to the television. Further, sometimes people use additional pre-amps, amps, etc... and those require an "out" from the receiver.
