Help me spec my cinema room

Nothing wrong with mine. One of them ran all 5 channels for a good 2 years and the second one has only recently been taken out of the box.

The Processor did die recently, but that was a known issue with one capacitor bulging/dieing. Soldered in a new one for £2 and all working again. Not perfect, but not bad either.

Yeah the Processor is essentially an Emotiva UMC200.
 
@-Ad- amazing, cheers for this.

Final things I need to clarify in my own head:

1) Can you use whatever pre-outs you want whenever you want? Since pre-outs don't actually use much power from the AVR are they always active and can I use them in any combination I want?

The wiring diagrams for the wiring for the SR7012 (http://manuals.marantz.com/SR7012/EU/EN/DRDZSYrjomlmpo.php) suggests that you need to use very specific combinations of pre-outs and amplified outputs...

2) Dual sub outputs. I'd always just assumed you'd need one sub and if you ever wanted two you could just split them (which it appears you can do) but the purpose in having two dedicated sub outputs seems to be the fact you can change timings between them (depending on distance to the listener)

The SR7012 appears to physically have two outputs but only lists 11.1 capability in the wiring diagrams etc. Does this mean the second sub output is just a dumb connection that physically allows me to connect a second sub without a splitter but won't allow me to change delay timings?
 
Correct budget avr only allow summed duplicated sub outs. Higher end avr and available pre have two separate sub outs which are calibrated separately.

You can use any pre ours you want is maybe just center and rears, but center pre out is fixed for center.

Unless it has function to change ie rear can be changed to front biamp. Read the avr manual.
 
No problem :)

Good question. It seems from the manual that you can use the pre-outs for surrounds/heights etc, but it doesn't show a combo with a power amp for front speakers. But it does have pre-outs for everything, so should work.

I can't see an issue, but it would be best to ask Marantz directly as they could have done something weird internally.

Yes, with one channel you'll not be able to tweak them separately. I've got around this by using an old school Behringer feedback destroyer (FBD). One Sub out from my processor goes into the FBD, then this has 2 outputs (to separate subs) and each channel has it's own parametric EQ.

Think of it is a budget manual way of configuring subs compared to something fancy like DIRAC/Antimode/MiniDSP for a budget busting £30. I then use a laptop and radioshack SPL meter to tweak everything using REW...... Well I did years ago and haven't got around to it yet for the new system as it'll take a whole weekend of fiddling to do it all!

The SR7012 should do 2 subs calibrated seperatley.

'To use two subwoofers, set “Subwoofer” to “2 spkrs” in the “Speaker Config.” setting.

The level and distance can be set separately for Subwoofer 1 and Subwoofer 2.'

Not sure it does that afaik, need to go higher end possibly the AV preamps.

Lastly time looked into that only higher end ones or lexicon mc-12 marantz av8803 etc

Not really worth it if having to spend loads more on a processor.

Might as well just plump for a bigger single sub like an Arendal Sub 2/3 or big SVS, then position and EQ it properly.
 
Also think you need the top end audyssy room multixt 32? As that does dual subs lesser ones don't.

What I find annoying as room eq is not done on HD audio as could is not fast enough to decode hd plus eq on top. It'll just do room eq on dvd audio, not bd hd audio.
 
The SR7012 has MultEQ XT32. Its pretty almost the same as the latest SR7013 which is £1400, I doubt they will be available much longer.

You need to have subeq HT, to eq dual subs.

SR7012 manual (http://m.us.marantz.com/DocumentMaster/US/mz_SR7012_om_u_en_v00.pdf) suggests that it has Sub EQ HT

Discrete subwoofers and Audyssey Sub EQ HT™ (v p. 211) The unit has two subwoofer output capability and can adjust the level and delay for each subwoofer individually. Audyssey Sub EQ HT™ makes the integration seamless by first compensating for any level and delay differences between the two subwoofers and then applying Audyssey MultEQ® XT32 to both subwoofers together for improved deep bass response and detail

  • Audyssey MultEQ XT32, LFC, Sub EQ HT, Dynamic Volume and Dynamic EQ
I think it will do everything you want, like I said before you would have to spend significantly more to better it.
 
Only issue with AV is hdmi spec it's changing all the time, reason why stuck with nonhdmi lexicon mc-8. Pretty much does every I need for now granted I don't have hd audio or full room eq..

New hdmi is pretty good by looks of it major improvement.

That as feature set I need bump up price to ridiculous levels.
