The right way to Bi Amp on Denon AVR3806

I have found in one review of the AVR3806 that is possible to Bi Amp the front speakers in a different way that is included in the user manual .
Routing the front pre-amps out feedind the VDP imput and assign the sorround back amp to Zone 3 . Then to select the VDP imput to play in Zone 3. Finnaly to connect the speakers terminals of the SBack to the front and right LF speakers terminals. This way let you adjust the volume of the Zone 3 to increase or decrease the LF ratio on your speakers. Is this a better way ?, and most important ┬┐Is this the correct way?
Thanks , Jorge from Argentina

SOURCE: Denon AVF988 to power amp to whole house speakers

jbell302, Check both remote spkers for operation from the A spks output if good, switch B remote spks to A main connect & main A spks to the B remote connection on the Denon spks outputs . Most amp sources do not like different ohm spks types & different cable or spks A-B. lenghts, because this makes up to resistances problems, making the amp to work harder & understanding what is going on. THE AMPS PROTECTION CIRCUIT IS AT ALERT & TRIES TO BALANCE THE RESISTANCE VOLUME. Best move is to try use the same spks. lenght & a higher qauge wire; 12.14.18qa. to better balance the output volume! All matching spks. pairs would help alot as well!

SOURCE: Hi, I have a Denon

zone 2 volume can be adjusted by zone2 remote control (small one which came with the unit) or by main remote control if you switch it to zone2 mode. My main rem control has a slide switch i have to put in zone 2 position to operate zone 2 amp.

How To Bi-Amp And Bi-Wire Speakers!


What is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but separately connecting that power source to a woofer and a midrange/tweeter on a speaker.

Bi-amping is using two separate power sources (amplifiers) and connecting one amplifier to a woofer and the other amplifier to a midrange/tweeter on a speaker.

How do I bi-wire?
Your speaker must have two separate positive and negative connections (one set for the woofer and one set for the midrange/tweeter). Connect one wire between the positive terminal on the amplifier/receiver the positive terminal on the speaker. Connect the other wire from the negative terminal on the amplifier/receiver to the corresponding negative terminal on the speaker. Remove the jumper straps connecting the two sets of speaker inputs. Repeat this process for the second set of terminals on the speaker, connecting them to the same positive and negative terminals on the receiver/amplifier. Repeat the steps for each speaker you wish to Bi-Wire, connecting them to the appropriate terminals on your receiver/amplifier.

How do I bi-amp?
Bi-amping is similar to bi-wiring, but involves separate amplifiers: one for the woofer and one for the midrange/tweeter. Passive bi-amping involves a direct hookup between each amplifier and the speaker terminals. True bi-amping involves hooking the preamp to an electronic crossover that replaces the passive crossover network in the speaker. The active crossover then connects to multiple power amplifiers.

What technical requirements do alternative speakers for my newly purchased stereo unit have to fulfill?


Original speaker suppled with unit set up & matched, setting up your own speakers is a MINEFIELD. Best of luck.

It can be possible to bi-amp a pair of Klipsch RB-81 with this receiver for stereo listening, and if yes, how...


Bi-amping indicated that you have two amps, one for the tweeters, adn another for the woofer, in a two way system. If you don't have two seperate amps, you can use the speaker A & B outputs to run seperate speaker llines to each set of speaker inputs, but that will not be true bi-amping. Another alternative is to use jumpers to connect the speaker inputs together, this not needing seperate amps. Here's a link to the owner's manual:

Can i bi-wire the front left and right speakers


Not with this unit.

But WHY? Bi-wiring is a myth. Whether the channel's double wires join (dead short) at the amp end or the speaker end makes no electrical difference to the speaker or the sound. But it DOES get you to buy more esoteric wire. Cha-ching for them!!!

But to flip an old saying, believing is seeing (or hearing). Go for it if you want. Someone is always willing to take your money.

You can hook as many subs as you like since the Onkyo only provides the Pre-Out Line Level to the amp(s) that drive it (them). I run two myself.

Bi-wiring is a personal choice and some swear by it while some of us swear at it in a modern home environment. The premise of bi-wiring is that your amps or crossover networks **** to start with so you have to do all this work-around.

My $.02 is you add complexity, waste speaker wire (which can be expensive if you subscribe to the theory that wire can change the sound other than at the cash register, but don't get me started on that), amplifier resources, and MAYBE you'll think you hear an improvement. Perhaps if you lived in an anechoic labratory you might. I think it's a crock.

http://www.brilliancehifi.co.uk/how-to-bi-wire-speakers.htm

If you look at the second diagram you'll notice the fundamental electrical circuitry of the speaker wire is essentially unchanged except you now have twice as much speaker wire. The same amplifier output posts still feed the same speaker input posts. How can this be electrically different?

You'll rarely find anyone who can produce a measured audible difference with any of the snake-oil schemes to get into your wallet. It's always flowery prose and faith.

Bi-amp


After examining a picture of a 5802 ( I have been servicing adcom for over 20 years ), these are not bi amp posts, but bi wire posts.

Bi-amp means that 2 amps are being used, one for highs, one for lows. This means that you have no crossovers in the speakers, instead, you have an electronic crossover between the amps and the pre-amp. The highs and lows are separated in the electronic crossover. One amp handles the lows, one handles the highs.

Bi-wire means that you have the crossovers still inside the speakers. The amp handles the full range of music ( highs-mids-lows ). Different kinds of speaker wire produce different results. If you have bi-Wire terminals on your speaker, they come with shorting wires, that tie the tweeter + to the woofer + on the back of the speaker, and the tweeter - to the woofer - . When the shorting wires are removed completely, you have now electrically separated the tweeter and woofer from each other, while maintinaing the crossovers ( inside the speaker ) for each.When this is done, you can now bi-wire the speakers and amp, and use different kinds of wire for the lower frequencies and the upper frequencies, depending on your ears ( everyone hears a little differently, thats why there are so may makers of components, and wire ).

Why do we have crossovers?.....the tweeter voice coils ( the things that make the sound ) are made of hair thin wire. This wire cannot handle much power and if you were to put bass in to a tweeter, you would burn the tweeter out almost instantly. A tweeter is a very light, fast moving device which can react very quickly to high frequency sounds ( symbols, triangles, guitar strings....). Woofers are more rugged. They have voice coils made of heavier wire and are designed for larger movements that Bass demands. Subsequently, woofers aren't very good for high frequencies because they are slower devices.

So what do we do ?.....Keep the lows away from the tweter and the highs away from the woofer.....thats the job of the crossover.

In the event that your speaker has the crossover OUTSIDE the speaker box, you should check ( as always ) with the manufacturer of the speaker to see how it can be changed to suit your needs. Remember to always read and follow your owners manual. Good luck....Rob
