Basically, I've got an outdoor theater with a 16'x9' screen out by my pool. I have 2 front and 2 rear channel speakers that are weatherproof Polk Audio speakers. For movie nights, I've pulled out the polk center channel from the rubbermaid box and brought the polk sub out from the house and running 5.1. I'm finding that's not only too much trouble, but the surround effects are lost on the audience because the viewing area is so spread out. Additionally, I need more "dialog", as the center channel speaker is underpowered for the dialogue, as it has to occasionally compete with the pool pump and the a/c unit.
I'm thinking I'd rather just go with a "2 speaker setup" where I pair the front and rear left speakers, front and rear right speakers, and do away with the center channel, the sub, and the surround sound concept altogether. What I DON'T know is how to implement that? Do I tell the blu-ray player I only have a 2 speaker setup? Or do I tell the receiver "even though you're getting the sound from the blu-ray player, I want you to only play it over the left and right channels"? Can I ask the receiver to split the signal to the front AND the rears? Or do I have to twist them together and just run them as one left and one right?
Welcome. Your manual holds the answer, just put the AVR into 7ch Stereo
in which all content is mixed down to 2ch stereo and sent to all available speakers. No unorthodox wiring needed. Boom, done.
If dialog is "lost," then yes an outdoor Center speaker will help, but you may need more power (see below), and viewers will need to be in a "centered" MLP to enjoy the film. If people are spread out around the pool, then just playing the soundtrack in 7ch Stereo will enable more people to hear.
For your application, the AVR could be underpowered, and the speakers may also not be up to the challenge of battling with ambient pool sounds and an a/c unit. I don't recall, but if the 579 has PRE-OUTs, you might look into an outdoor amplifier solution. Monoprice probably has an economical solution. But try 7ch Stereo mode first at close to -0 dB and see how it you (and the audience) like it. A outdoor pool area is a much-less-than-ideal listening environment, so I'd give up the idea of acoustic accuracy and just settle for "I can hear the dialog."
