Can my yamaha amp do this

I've installed a built in unit housing the L/C/R speaker. The left and right speakers are behind doors in the unit and the centre is in the open middle section. I don't mind having the doors open at night when the little one goes to bed but not in the day when she's up.
Is it possible to set the amp to just use centre or centre and rears for daytime use, maybe with the scene settings?
 
I've got the RX-V683 and almost certain you can on that, although not in the way you describe. You'd have to go in to the settings each time and disable the speakers then re-enable them when needed. You couldn't do it via scenes or anything like that though
 
I think on mine there is was a custom configuration option which enabled you to specify speakers to use. I'll double check when I'm home
 
How do you disable left & right? I think only my Lexicon offered a mono mode, but unsure if it upscaled mono to 7.1 or just duplicates mono to all channels (or has option of both)
 
how about just using the tv speakers in the day ? also the speakers in the unit , have you given them enough room the breath ?
 
You can do this with PC receiver manager software on the RX3067, the software makes it a lot easier to setup. It allowed you to have two separate speakers setups saved and add them to a scene. I used this for audio playback to allow full range to the front speakers and disable all other speakers & DSP so no audio delays were introduced when playing the same audio on multiple zones. I would be surprised if this wasn’t carried over to newer 1073.

It looks like the software is now redundant on newer models but you can access it via a browser if the receiver is on the lan, http://x.x.x.x/setup
 
The option in the Yamaha amps to run different speaker configurations is called Setting Pattern. It's available in the speaker set-up menu pages. However, there's no valid configuration that doesn't have the main stereo pair. IOW you can't switch off the stereo pair and have just the centre running.

The Scene Preset function memorizes source and audio processing modes. If you wanted to run in stereo mode then Scene Preset could handle that, but since there's no way to select a mode that runs with the front stereo pair switched off then that's a bit of a non-starter too.

The Mono Movie sound processing preset takes mono audio and passes it to all speakers with some ambient processing to replicate an old style movie theatre. It doesn't switch off the front L&R.

I considered whether it would be possible to use the individual speaker level control to raise the speaker levels for the centre, surrounds and sub and reduce them for the stereo front pair, but the maximum amount of difference is only 20dB, and that presumes none of the other speakers need to be trimmed in level. As soon as you start to see + and - dB trim levels on the individual speakers in their standard set-up then that reduces how much of a difference it's possible to make between them and the stereo pair. A maximum of 20dB isn't really enough to silence the fronts, and anything less is going in the wrong direction.

Incidentally, I also considered whether it would be possible to access the Setting Pattern function via discrete IR commands but so far I haven't seen anything in the code sheets that makes that possible either. I checked what happens in Scene Preset. It changes a lot of stuff but doesn't alter which Setting Pattern is in use.

So far the only practical answer other than involving manual speaker switches would involve powering the front pair from a stand-alone power amp with 12 volt trigger. The 1073 has pre-outs and configurable triggers that can be assigned to an input. It's just a bit of a sledgehammer to crack a nut.

What it comes back to then is either a manual speaker switch to isolate the front stereo pair, or modifying the cupboard doors to inset some speaker grill cloth so the speaker can be heard with the doors closed.
 
The tv has no speakers and everything is setup using arc so TV and amp switch on together.

The left and right speakers are front ported so no problem being in the cabinet but I may wrap some acoustic damping material around them just to stop any cabinet resonance.
 
I was just looking at setting patterns before I read your post lucid and wondered if I remove the L/R speakers and run ypao whether it would set a pattern for just the speakers the mic hears?

Well none of the Yamahas I have used, set-up, or owned have allowed the front stereo pair to be edited out of the speaker set-up configuration. Maybe your 1073 is different, but I'd be surprised if it is.

If you're talking about physically pulling the speaker plugs (same result as using a switch) then running YPAO, honestly, if the amp is clever enough to work out phase and speaker distance and crossover frequencies and EQ, and then do all that for multiple seating positions in the room then I very much doubt it'll overlook the missing front L&R channel signals. What do you think?

My bet is it'll halt at Front Left then give you the option to fix the problem or quit the set-up.

There's nothing saying that you have to run YPAO for say Pattern Setting 2. You could balance up manually, or run YPAO as normal and then disconnect the fronts after. That's what you'd be doing with a speaker switch anyway. But neither of these would change how the amp deals with incoming signals. It'll still send music, effects and panning cues to the missing speakers. There's not much you can do to change that apart from find an AV amp or pre-amp/processor that does allow C + SL + SR + SUB etc as a valid configuration. It might be a long search though.
 
yeah having power amplifiers are one way to do this, although bit extreme just to get this. But I could do this a while ago, as I had a two channel for L/R and another two channel for center, biamping, so if I wanted to watch a mono movie, with only the center on, I only switched the center two channel amp on, and used a mono DSP mode in the Lexicon.
 
My hope was if no L/R was detected it would mix these into the centre channel but as you say it just reads an error and stops. It's not problem I can either remove the doors or just open them when used.
 
I used to have an old Yamaha amp, and I could change between: 2.0, 3.0, 5.0, centre only

I cannot for the life of me remember how I did it though - pretty sure I would select a mode on the remote.

I was away during the week I have had a play with receiver manager, you can do this on the 3067 at least, it is not as simple as just turning off the speakers but pretty straight forward.

If you connect the L/R speakers to the biamp terminals and enable this mode in speaker pattern 1 they work as normal, then in speaker pattern 2 put the amp in normal 5/7.1 the L/R speakers will go off. You can assign these patterns to a scene.
 
Don't you lose L/R information then? I think I'm just going to have to compromise with either quality over aesthetics or aesthetics over quality
