Can Anyone help me out with this one.

I have a client who wants to put a TV on one wall and project a projector image to an opposite wall, and have some form of in-ceiling speakers for both!

Obviously this is going to cause some issues in regard to 5.1 speaker placement. (he does not want 10 speakers in the ceiling)

As a work around can we set up for 5.1 for the projector end with the two rear speakers being stereo speakers which we can cable left side of the speaker as surround (zone 1) and the right side as zone 2 front for the TV end of the room?

Therefore giving us 5.1 for the projector and 2 channel for the TV

I can configure the controll system so that zone 1 and zone 2 are never used at the same time.

can someone tell me if this will work please?

bad idea at least in theory. that's an equivalent to short circuiting the amps!

the only sensible option is to use preamps. connect preamps to an amp which controls the dual usage speakers. but this is really unnecessary and tedious to setup right. and if something becomes faulty it could be nightmare to trouble shoot. but if he gets what he wants that's the way to go ... perhaps use preamps for the entire setup?

Stick in the extra speakers... strange that they don't want to do that, I would want 5.1 (well 7.1) for both the TV and the projector.

Curious setup but if thats what he wants lol. Are both displays going to be showing the same thing, because if they are quite a few high end av recievers have dual hdmi outputs.
If they're going to be showing different things then theres either gunna be 10 speakers in the ceiling or one setup won't be 5.1.

you can double wire, but the user MUST make sure the 2 amps are not turned on at the same time. when only one amp is on, there is no short circuit. but if for any reason the 2nd amp is turned on the circuit is technically a short circuit - smoke and fire should follow at some stage.

No, even when off there is signifigantly low impedance across an amps output that it will load the other amp, and it will be non linear so really mess with the sound.

I would be looking at a speaker selector powered by one of the 12v triggers on the 5.1 system to change over the speakers from the TV to the reciever. Sure I have seen some somewhere before for not much (in the scale of inbuilt audio gear)

Why not do what most people do and have the projector project on the same wall as the tv?
Just have a motorised screen come down in front of the tv when the projector is in use.
That way you can have surround sound for either using same speakers and amp.

Fully agree, How would the seating work if he had the screens on opposite walls. I mean you would need a large room.

Yea and if the room is that large then I would put in a surround sound system with amp for each screen.

I agree with all of the above and have already suggested that - but he doesn't want  a screen!
And it's not a large room - I think the couch is going to be turned around to watch the projector!!

I Think I will just go for two in wall speakers for the TV (or maybe look at a sound bar wall mounted under the TV)

I can see that turning into something that leads to either the project being used very infrequently (to the point of never)

What sort of wall is it?  Having used projectors with and without screens - I can vouch that the odd rugby game is fine, but movie watching can be soured if the wall isn't a nice pristine wall.

lookie here - the customer gets what the customer wants! even if it's so darn mind blowingly silly! richms has a good plan.

the other way is to have a in-ceiling TV and/or projector screen. one of them descends from above and the other one fixed to the wall. or both descends that will make the room magnificently multipurpose.

Having tried a grey wall for a projector before I can say it sucks compared to a real screen.

Sure, its better than an old bedsheet etc, but getting a smooth paint finish is really hard when you are lookign at it. On a normal wall you are looking at stuff on the wall, not the wall itself.

Agreed, but you can almost already hear the complaints from the customer ...
