Bought a new Receiver. HELP PLEASE!

[xtreme02gt]

I have the RTi12's and I want to bi-amp them, can someone please help me out with this. I am a newbie to this, and don't quite understand it. I have the TX-NR807, is there a website were I can see how it is wired up? PLEASE need some help with this.

If you bi-amp the front towers, does that double the power to the fronts? And is there some thing I have to change in the settings in the receiver?

If you bi-amp the front towers, does that dubble the power to the fronts? And is there some thing I have to change in the settings in the receiver?

All the info you'll need to understand what it is and how to do it is right here in this sticky from Jomari:

Bi-amping/Bi-Wiring Reasearch Material

For a really quick answer.....bi-amping will seperate your highs and lows. And yes, you will need to change the setting in the receiver to "Bi-Amp." A lot of members have stated that they heard little if any audible difference (myself included), depending on many variables. Just keep in mind that this procedure means you will need to go to a 5.1 set-up, as the rear surrounds speaker terminals on the back of the receiver will be used for bi-amping to your front towers.

Well, at this point I am only running 5.1. Till I can figure out how to set the room up so I could run 7.1

Plus, right now there are very few movies out that are 7.1, most everything is still 5.1 right?

So are you saying Bi-amp does nothing?

yes, most is 5.1, you need to go into the receivers menu to switch it to bi-amp mode, then run the surround back left speaker wire to the left speaker and same for the right. just make sure your towers have dual binding post and that you remove whatever bridge is connecting them, typically a brass connector.

But does bi-amping double the power going to each speaker? so after bi-ampimg them will I be sending 270 watts to each speaker?

No, you are just seperating the higher frequencies from the lower ones for what some people hear as better clarity in the sound. I heard no difference. Some will say that you need higher end speakers so the sound reproduction would be distinct enough to actually hear any improvement in the sound, but I can't say if this is true or not.

when driving 7 channels simultaneously, your receiver is only outputing about 30 watts per channel. however when pushing 5 channels it seems to do much better and come in at about 105 watts per channel.

You may just want to leave it at 5 channels or buy yourself an emotiva amp like the UPA-5 or XPA-5.

No. It has no effect on power output, as it only deals with seperating the high/low frequancies.

I personally think that unless your system is extremely revealing, bi-amping and bi-wiring is a waste of time, effort and money.

I agree, and so I believe the OP is referring to passive bi-amping if I am not mistaken....to get added power, you would need an additional power source and that is called active bi-amping. Is this correct John?

No. Bi-wiring, active/passive bi-amping all only deal with frequency seperation, but each in a different manner.

To obtain more power output you can bridge 2 amps for each channel, or you can change your speakers to a lower impedance model (4Ohm).

At least that's the way I've always understood it.

What amp should I buy? I really only want to amp the fronts. What is the best amp for RTi12 towers? My center is the Klipsch Quintet III, with the rear speakers also being the Klipsch Quintet III.

That is what I meant by active bi-amping. I wasn't referring to passive bi-amping or passive/active bi-amping. I think the OP was talking about passive bi-amping only.

All this BI is starting to get me worried!

And yes, he is talking about passive bi-amping. It's a waste of time.

I have to agree with you based on my experience with it.

[xtreme02gt]

So are you guy's saying I would be better off, Buying the Yamaha RX-V665, and a Emotiva XPA-3 amp than buying this Onkyo TX-NR807?

In a word......yes.

If money is not an issue, using the 665 as a pre/pro and powering your front speakers and center with the XPA-3 would be a solid improvement in the clarity of the sound over just the 807 alone.

I agree with Fors!

And I might add.... Invest in some decent cabling for your front soundstage as well. That will make a much more substantial difference than any bi-wiring or bi-amping you were thinking of.

Well, I havent even taken the 807 out of the box. So I will take it back to Frys and trade it in for the Yamaha V665. And then just buy the XPA-3.

But How good is the Yamaha in sound quality? And as far as the Klipsch rear speaker, just run those off the receiver? and do you think 90w will be good for the rear surround speakers? I still would like it to be nice a equal sounding. What do you guys think about that?

The sound quality will be mostly dictated by the XPA-3 and not the Yamaha. The Yamaha will do the tuning and processing, but the XPA-3 will supply clean, efficient power that the 807 could not do, and this is where you will hear the impoved quality of your audio.

Yes, you would run your side and/or rear surrounds off of the Yamaha...which can sufficiently power them for your set-up. .

For a balanced sound, make sure you run the Yamaha calibration set-up once you get it, and then perhaps follow this up with an SPL meter if you still feel the surrounds cannot keep up with the fronts and center. The SPL meter will balance the channel levels of all of your speakers. You can find all you need to know about an SPL meter from this sticky from Big Daddy:

Calibrating Your Audio with an SPL Meter

For your speakers, after calibration, I would set them to "Small" with a crossover/high pass filter for your speakers at 80hz across the board (maybe even the side and rear surrounds at 100Hz). You'll need to go a good 10-20Hz above the lowest frequency rating of your speakers to allow for "head room" or to avoid clipping at higher volumes. 80Hz is THX recommended and a good starting point.
