    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.

    Far simpler to simply omit the Centre Speaker and set the AVR to 'No Centre' and allow it to generate a phantom Centre using the Front LR.

    it's far simpler to just put a pair of headphones on and create a phantom center in the middle of your head. I'm kidding.

    There is more to my op than what you are stating Joe.

    I can't imagine why you'd want to do this, it seems like an over-elaborate solution to a problem that doesn't exist.

    Gavtech,

    Why were they deleted? They were valid links.

    DCS0760, they destroyed your idea already in Audioholics. Why you want to repeat this here?!
    Bored or just too much free time in your hand?

    And your idea is nothing new, I and probably many people more tried this 20 years ago when all 5.1 stuff was very new and exciting. It is not a good idea.
    Your links are probably from people who can't operate receivers properly or have faulty item. I never used receiver (and I used alot of these) , which cannot decode stereo sound into center channel.

    I'm still not getting this one - do you have some pics/drawing to highlight the 'problem' you are solving.

    Citywalker,

    Was the setup you tried 20 years ago exactly the same as the one described in my OP?

    I have not seen any mention of others having tried a similar design which allows for the options mentioned in the OP.


    or maybe I'm wrong.

    Joe,

    What are you confused about? The setup (how to configure the design) or it's usefulness?

    Joe,

    It's not a requirement. Its something that I think creates some useful options/alternatives.

    No. Your system is pointless right now and in the future too - if you can't prove your idea.

    Some questions for you :

    1. Show the receiver model in today's world with a/b speakers as you described
    2. Do a diagram, how you connect the system
    3. Describe the benefits

    Check out the following link:



    TV Sound Quality | Dolby Atmos Soundbar | Acoustic Surface | Sony US



    Sony is introducing a new feature that offers options that are similar to what I describe in the OP. Sony is maximizing the usefulness of the tv by giving you the option of utilizing it as is (soundbar comparison) or as a center channel.

    'Sony is introducing a new feature' - not exactly 'New'. Many of Sony's old Rear Projection TV's had the option of configuring the onboard loudspeakers to work as your system Centre channel, otherwise placing a Center channel Loudspeaker was a bit of a challenge with a floor standing TV cabinet.

    I can see that being useful for people who don't want speakers, but using it as a centre channel would be awful... unless Sony plan on making some flat panel speakers that tonally match the TV.
    Your front 3 need to match.
