If you look at this picture, you will notice that for the Front Speakers this receiver offers for Speaker A two connections - a Right and a Left. Same thing for Speaker B.

I understand that you can have two Right Front Speakers and two Left Front Speakers using two separate connections since the receiver allows this. Question is, does bi-wiring mean
- taking Speaker A Right +/- and connecting to binding posts of speaker Right +/- and taking Speaker A Right +/- and connecting to binding posts of speaker Left +/- [since I have only one right front]

or

- taking Speaker A Right +/- and connecting to binding posts of speaker right +/- and taking Speaker A Left +/- and connecting to binding posts of Speaker Left +/-

This scenario described is only for the right front speaker. I've left out the left front part intentionally.

bi-wiring has to do with seperating the signals going into a speaker.
basically, you're gonna have a pos/neg for your high end and a pos/neg for your low end. seperating those signals provides a cleaner signal and allows an easier load on an amp usually. so in your case, you wouldn't gain anything w/ bi-wiring since your speakers are not bi-wireable.
the other option that you could be looking at w/ that picture is presenting a 7.1 channel signal or something of that sort, front right, right center, left center, left front etc....but that doesn't seem like it from the picture

I don't know what you're trying to achieve. What you're describing isn't bi-wiring. Its just taking the A and B terminals and plugging them into the same input on your speaker, assuming your speaker only has 2 binding posts, 1 for positive and 1 for negative. Is this the case? If so, then its a futile attempt. If your speaker has 4 binding posts and is bi-wireable/ampable, then you could theoretically connect 2 different sets of speaker wire from your front L/R of your receiver to each of the 2 sets of binding posts on your speaker. However, the effects of bi-wiring is controversial. Personally the only reason I do it was to experiment, I don't hear much of a difference even on my Tag McLaren AV32R + Rotel RMB-1095 on PSB Stratus Gold i speakers, so I don't think its gonna do much for your Denon 2802, unless you're talking about really long runs, in which case all it'll do is increase the overall gauge of the speaker wire.

What speaker do you have anyway?

Nevermind fellas.

I got the answer I required.

FYI tho, my speakers are RF-3II that allow bi-wiring.

I just posed my question incorrectly.

According to my read of that picture of the amp, the A/B place is just so that you can have 2 sets of front speakers hooked up. So you could put a second set of speakers in another room in the house and drive them for stereo music. The receiver is not a 7.1 channel receiver, otherwise on the input part of it it would have the extra 2 channels as well.

The A/B speaker setup has been around for years to allow you to have speakers somewhere else other than the room with the amp and be able to drive them should you want. Something like in the bedroom to play the sexy music, or something like that. :)

pics of your speakers probably, they're Klipsch's right?

Anyway, IIRC the 2802 supports some sort of "6.1" setup, so the "surround" channel are your normal surround left and right speakers, while the "surround back" is probably a matrixed channel to be placed directly behind your seating position, for use with "6.1" setups like THX/DD-EX and DTS-ES Matrix.

Why don't you just read the speeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeecifications?

<< Multi-Source Function: The Multi-Source function lets you enjoy one program source in a second room, while another source is playing in the main room. >>



<< B Speaker Outputs
Speaker terminals on the receiver that let you connect a second set of speakers. They use the same stereo signal as your main speakers, and are not used in surround sound. In some receivers with multi-zone output, the B speaker outputs are used for the second "zone." >>

The benefit of bi-wiring is dubious. The benefit of bi-amping is not, which is really what dual terminals are for on the speakers that have them.

That's true to a certain extent. Bi-amping with an external active crossover may yield different, if not better results than using the internal crossovers of the speakers. Some speaker manufacturers just put dual binding posts for marketing reasons rather than for their sonic benefits. Dynaudio is an exception that I remember, since they firmly do not believe in the benefits of bi-wiring/amping.

HERE is a picture of a bi-wired speaker. In order to achieve the effect of bi-wiring, both your speaker and amp must support it. And, unless you have cable designed for bi-wiring, you must make two runs of cable.

That's not true, any 2 amps can be used to bi-amp. I'm not sure that bi-wiring, which is different, is worth doing.

Well that would depend on the speaker...assuming they didn't just put the extra terminals on for show I'd trust the designer to know
the best crossover implementation for that model.

Muncla, what exactly do you mean by that? Obviously your speaker must have dual sets of binding posts, but what do you mean by the amp supporting it? Any amp can be made to bi-wire by simply running 2 sets of wires to the same terminals on the amp.
