Home Theater Design Setup To maximize the usefulness of a single av receiver connected to a 3.1, 5.1 or 7.1, etc. speaker setup (utilizing 2 speakers as a center channel, located under the television). The same equipment will allow you to configure any of the speaker configurations already mentioned, but will also allow you to utilize/configure the existing 2 speakers being used as the center channel as front left and front right for a 2.0 or 2.1 configuration. (Please note, that you will still be able to configure/use the traditional Front Left and Front Right located on the sides of the screen for a 2.0 or 2.1 configuration) This allows a user to have all the benefits of a 3.1, 5.1, 7.1, etc setup but have the option of a quieter/more intimate/subtle experience of a "centrally" positioned 2.0 or 2.1 set up; while still enjoying/benefiting from the quality of independent speakers (when compared to most soundbars). This also provides a more balanced listening experience to those seated on the sides of the screen. This is accomplished by changing/manipulating the speaker configuration and speaker A/B function via the av receiver menu. Receiver and speaker set up: 1-The Center channel output from the av receiver is connected to a speaker selector switch, splitting the signal from 1 to 2 (As has been mentioned in numerous other discussions and forums). 2-Connect speaker wire to the av receivers Speaker B connectors. 3-Utilize/incorporate an Automatic A/B source selector switch. 4-Connect the 2 center channel signals from step 1 to the input B on the Automatic source selector. 5-Connect the Speaker B wire from the av receiver to the input A on the Automatic source selector. 6-Connect the output L/R from the Automatic source selector to the two center channel speakers. This can be simplified if there was an av receiver with 2 center channel connections and the ability to assign/switch their use between center or front right and front left.
