Could I do this with another Yammy 2500?

[Doug917]

I currently have a Yammy 2500 and am wanting to be able to run 9.2. I can't afford to get the Z9 any time soon. Could I buy another 2500 and use just the surround back and sub channels and force PL2x all the time? I'm thinking I could use the optical outputs (1 for DVD and 1 for CD - the only 2 sources I have hooked to the unit) and run them to the corresponding inputs on the 2nd receiver provided there wouldn't be an audible delay. I would have to balance the channels on both receivers, but then when I hit the power on or off button or the volume or DSP mode, it should have the same effect on both receivers. It's late and I may just be out of my mind, but I think this would work. I should also be able to use one of the 2500's internal zone 2 amps for another room. Has anyone else done this or anything similar? If it works I would have an RX-5000 .

 

[Doug917]

After less than 5 hours sleep, I'm up and thinking about this again. Unfortunately, all the older equipment I have does not have any optical inputs or I could try this crazy idea out and at least see if the output form the first receiver would get a second piece okay. I would have to find someone who has tried this, or buy another 2500 and hope for the best. If I did buy the receiver and it didn't work out, I could always use it for my living room setup. I just don't want to throw the kind of money I would need to at a Z9 when I feel its replacement will be here within a year or so and will improve in many ways. I don't mind plunking down ~$500 for something that could be used in antoher less important room when I do a massive upgrade in the future. I know everything will be outdated almost instantly, and if the Z9 was at the beginning of its life, I would probably think differently. I still think my crazy idea would work. Can anyone prove me wrong?

Room Acoustics!


























Seriously, if I understand your posts correctly, you would run the two 2500s in series. Why not run them in parallel? I've taken a look at the manual for the 2500 at Yamaha's site and figure that if you take both a coaxial and optical digital cable from your DVD player, you could feed one 2500 with the coaxial and the other 2500 with the optical. In this way, you wouldn't have to worry about potential audio delays between the speakers from one 2500 and another 2500.

DVD players, or at least those I've ever owned, output from all jacks simultaneously.

Also:

Has anyone else done this or anything similar?

You should be able to test this with your existing 2500 simply by removing all the speaker connections apart from those that would be on the proposed 2500. No?

Miester,

I have got my room in much better shape now. I have acomplished this by using the "Natural" equalization instead of "front" and by moving the subs. I have also tweaked the parametric EQ on the 2500. I now have only a 7dB spread from 20Hz to 20kHz. Now, I want 9.2!

I have thought about running the 2 receivers in parallel, but would the optical and coaxial have any timing issues as well? I wouldn't think using the optical in/out option would even create a noticible delay. As far as I am thinking, it should simply be a passthrough and at the speed of light should be undetectable by me.

Was this figure obtained using the Rives disc or ETF? ETF will let you look at the frequencies between those on the Rives disc. In the 20Hz to 200Hz region, without some form of room treatment, I'd be amazed if you had just 7dB of a spread; especially with all those smooth wooden surfaces in your Home Theater.

I have thought about running the 2 receivers in parallel, but would the optical and coaxial have any timing issues as well?

I can't imagine so. I believe the two signals should be perfectly in sync.

I wouldn't think using the optical in/out option would even create a noticible delay. As far as I am thinking, it should simply be a passthrough and at the speed of light should be undetectable by me.

I suspect it probably would be undetectable as you say, but why take the chance when you don't have to?

Miester,

The eq measurements were with the rives disc. I have not gotten around to the ETF yet, but must admit, the system sounds much better already and I am quite happy with it.

If you are happy with things as they are, then whatever you do, don't use ETF! If you do, you will only be appalled!

....Buckle, at one time we liked speakers we outgrew....what sounds good to someone now, you may have moved past.....

.....guys, this is a hobby....buy components better than a few price-levels above, "to you", and you'll lay out cash at fewer levels....over.....

 

[Doug917]

It's funny (or sad depending on how you look at it), but I could not hear the 16kHz and 20kHz signals on the Rives CD. I know they are there and being reproduced as I can measure them with the SPL meter (guess I don't need to worry about EQing those frequencies. I guess the hearing is getting worse as I get older, it happens to all of us (the wife couldn't hear them either). Now I just need some vision problems so I will be totally content with 480p.

No no Mulester7. If I understand you correctly, I don't mean to imply that I've moved past Doug917 (or anybody else for that matter).

True, but human nature being what it is, I tend to believe that most folk stretch their budget at present.

Out of curiosity, did you note what the upper limit of your hearing was with the CD?

Regards

 

[Doug917]

I could easily hear the 12.5kHz signal, but not the 16kHz or above. So, it falls off somewhere between 12.5kHz and 16kHz. Are you able to hear anything above 12.5kHz?

 

[Doug917]

My wife thought she could hear the 16kHz signal, but when we did blind tests she could not.

 

[mulester7]

No no Mulester7. If I understand you correctly, I don't mean to imply that I've moved past Doug917 (or anybody else for that matter).

.....true humility, Mr. Scotland....and yes, Buckle, when it gets down to you're barely eatin' and wearin' with three system components ordered, you may have a problem with this hobby.....apply two 901 equalizers and call me in the morning.....rover.....

I personally think 9.2 is a waste unless you have money to throw away. Think about it, you'll have 2!! 2500's. You could wait a little, and then get 1 Z9.

As far as hearing. I don't know how high I can hear. I'll put it to you this way, I used to paly in a band that practiced at 125dB's.....

...I could not hear the 16kHz and 20kHz signals on the Rives CD.

I never checked below the 50Hz tone since I was considering my towers which are rated down to 48Hz. Besides, since the towers are crossed to the sub at 80Hz, it was somewhat academic even checking the 50Hz and 63Hz tones.

I could easily hear the 12.5kHz signal, but not the 16kHz or above. So, it falls off somewhere between 12.5kHz and 16kHz. Are you able to hear anything above 12.5kHz?

I can hear the 16kHz, but not the 20kHz tone. Given that I can barely hear the 16kHz tone, I reckon I can hear to perhaps 17kHz. Actually, I've just realised that I can use the tone generator function of ETF to check the actual limits of my hearing. Hmm...

Jerry rigged 9.1

Concerning your proposed setup, as I understand it, the Yamaha presence channels widen the front sound stage by moving some of the information from the front and center channels to the presence speakers. If you add the presence speakers (receiver #2) and without modifying the output to front and center channels (receiver #1 in 7.1) than the result will probably be screwed up. Consider connecting the 9 speakers and running your receiver with presence OR 7.1 like it was designed.

On second thought, buy the extra receiver. If it doesn't work, send it to me

 

[gcmarshall]

is a 7.1 speaker setup useless unless the soundtrack being played is recorded/formatted for 7.1 sound? seems like just about every movie i watch is DD 5.1 or DTS 5.1. so, i have a 5.1 speaker set up. what does having the extra 2 speakers do for me when watching these DD/DTS 5.1 movies?

 

[Doug917]

JcPanny,

I don't see what would be screwed up. One receiver is forced to "presence" and the other is forced to "surround back." I was assuming I would use one receiver for the front/prensence channels and 1 sub. I would use the other receiver for the 4 surround and one sub. What you consider "jerry rigged" I consider "strategery" (a little George Bush humor there)


Sheep,

Have you experinced a well set up 9.2 config? I would love to pick up the Z9 but something that complex I would want to buy through an authorized dealer for the warranty and I'm about $2600 short right now. That's more than a little wait when you work for a school district.


gcmarshall,

You can engage all 7 channels (or in this case all 9 channels) on any source signal unless it is a mono signal.

 

[jcPanny]

On second thought, if the mains and presence are on the same receiver then it might work. It still seams like a chore to calibrate all the levels properly and controll both receivers to watch a movie, but it is your time and money. They don't even have any 7.1 channel media yet anyway (only 6.1) and when it comes out, your receiver wont play it.

My offer still stands. If it doens't work, you can send me the extra receiver.
