SBR/SBL pre-out Denon / RCA Dual input Sunfire

[Bernal]

It is convenient to use the Sunfire CAPACITY DUAL RCA INPUTS (SEE ATTACHED (R/L Rear) connect outlets SBR / SBL the DENON 4308Ci not use.
Connect The amplifier in the signal to take advantage of this channel and the best effects separate input signal and thus let the Sunfire with the speakers handle the mixture

I'm not sure what you're trying to accomplish.

What does it sound like???????

Hello ...
It is an idea that I have read the manuals.
Ok. If you put the processor in 5.1 follows the same rules defined (Dolby, DTS, etc.). And tried to get the best performance. If you put the processor in 7.1 surround and then add the side with the rear surround, you're playing dirty to the processor and the results can not predict. Only a specialist in these algorithms could explain what would happen and could vary from one to another type of surround (Dolby, DTS, etc.). This I think is the question?

[jimmydep]

Have you actually tried this or is it just theory?
It looks like your taking 2 sources and combining them, why not let the processor do what it was designed to do.......
The real question is: "what does it sound like".

Theory based on the manuals.
NO are two sources is a pre-amp and Amp

[jimmydep]

from your drawing it looks to me that your taking the rear channel output and the surround output from the receiver and combining them at the amp.......I'm not quite sure what the benifit would be.
Where have you seen this wiring diagram....It's not in my Sunfire manual

Is correct. That's the theory ....
Sunfire Manual page 14 "System Configurations. Connetions Typical ..."

I don't have a page 14, I'll go find one online..

Ok. This diagram shows a standard 5 speaker configuration, with each seperate channel from the receiver going to it's corresponding channel on the amp.

In your original diagram your combining another rear surround channel with the rear channel, so you have two inputs into 1 channel on the amp.

The wiring diagram in the manual does not match your wiring diagram.

[Bernal]

1) If Lucasfilm and developed the Dolby Surround EX in response to demands for more control of the surround sound field of digital multichannel sound formats (Dolby Digital, DTS or SDDS) because if you limit it to the cinemas this implicit HT 5.1 .

2) Strictly speaking, the Surround EX is an enhancement of the standard 5.1- channel scheme.

3) If Surround EX uses the techniques of the original Dolby Surround matrix encoding the third surround channel, called "Surround Back" or SB (ie, "effects"), in channels of discrete surround left (SL or "Surround Left) and right (SR or Surround Right") in the same way as a center channel is encoded in the two side channels of a mix encoded in Dolby Surround. Moreover, the extraction procedure of the channel is the same as that used in the Dolby Pro-Logic to extract the center channel: SL + SR = SB.

4) Playing with directional logic circuits in the decoder, corriege if I am wrong, it gives an effect as rewired the SB channel without splitting ... reaching EX DTS 5.1 to a system for domestic use.

Diagram page. 14 is 5.1 = 5.1.
My Pre-Amp is 7.1.
That's the theory.

IMO: Possibly....

[comfortablycurt]

To the best of my knowledge, there would be absolutely no reason to, or benefit from, this connection method.

I'm not sure if this would damage the amp...but I wouldn't be trying it myself.

What you're doing is combining the surround and the surround back channels into one channel at the amp. What are you hoping to accomplish by doing this?

Theory.

It is an idea that I have read the manuals.

It was a question of time. The effect. Combining the surround and surround back channels in a channel on the amplifier

"Another option that is becoming more common on 7.1 channel receivers is the use of Bi-amping. How this works is that if you have front channel Speakers that have separate speaker connections for the midrange/tweeters and the woofers (I am not referring to the subwoofer, but the woofers in your front speakers).

You can reassign the amplifiers running the 6th and 7th channels to your front channels. Then enables you to retain a full 5.1 channel setup, but still add two additional channels of amplification to your front left and right speakers.

Using the separate speakers connections for the 6th and 7th channel on your bi-ampable speakers, you can double the power delivered to your front left and right channels. Your front mid-range/tweeters end up running off of the main L/R channels and your front speakers woofers running off your 6th and 7th channel Bi-amp connections.

The procedure for this type of setup is explained and illustrated in the user manuals for many 7.1 channel receivers. However, as I mentioned earlier, although this is becoming a more common feature, but is not included in all 7.1 channel receivers."

[comfortablycurt]

This is completely different. It's not as if you'd be driving the speakers with any additional power.

You're doubling up the signal from the pre-amp, which doesn't create any power at all. All of the power comes from the power amp. If anything, this is like the opposite of bi-amping.()

I would think that could be bad for either the channels on your amp, or your speakers too. You're sending a single channel, 2 channels of information. This can't be a good thing.

[Bernal]

.... You're sending a single channel, 2 channels of information. This can't be a good thing.

That's the idea ... is to create a Y in channels
This is the best opinion on the subject, thanks.

[Bernal]

I think: 1) If the processor is set as 7.1. 2) Just add the surround to the rear surround side. 3) will be playing dirty to the processor and the results can not predict.
Will be better or worse (50% vs 50%) and altered the equation ... in the mix ... AVR because of happening but natural reaches of the RCA Amp and then to the speakers who must do the translation.
I believe that only a specialist in these algorithms could explain what would happen and could vary from one to another type of surround (Dolby, DTS, etc.). This I think is the question?

I agree; I can't exactly make out your preamp outputs on the first jpg, but nothing good will come of this....

Hi,
This is an important forum. Therefore a lead and learn. I have learned from your responses.
Thanks to all
