Impedance is fine. Moving on...

I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want to do and it works great!

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.

Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

You might be faced with the age-old Bose issue of a 4-ohm speaker set. The ohm rating must be compatible. Most receivers drive 8-ohm speakers. If indeed they are incompatible, then it's up to you which component you want to replace (I don't recommend trying to find a converter to use the Bose speakers). The receiver sounds like it is new, so perhaps the speakers... or return the receiver and get one that can drive the Bose.

SOURCE: compatable receiver list for Bose 901 series VI

I contacted the Customer support folks at Bose. Here is what they said: With a stereo receiver, the equalizer is run through the tape monitor section in the back of the receiver. The receiver's tape monitor output, left and right, runs to the amp input section of the equalizer, left and right. Then the amp output section of the equalizer, left and right, runs to the receiver's tape monitor input section. With a surround sound, home theater, type of receiver, the theory is the same, but the connection is through the preamp-out/ main amp-in section of the receiver. Not all receivers have this feature. Most, in fact, do not. Check the back of the receiver. There would be a connection made by two U-shaped clips. The plugs would be pulled out. Then connect from the preamp-out to the equalizer's amp input section; and from the equalizer's amp output section to the main amp-in. This effectively isolates the equalizer so that it is not affecting the other speakers in the system or the receiver's surround processing. Attached is a current list of known 901-home theater compatible receivers:
Note: Specifications subject to change without notice. Bose Corporation is not responsible for any inaccuracies due to manufacturer changes. Inclusion in this list does not indicate an endorsement by Bose Corporation. When in doubt contact the manufacturer of the equipment.

I have the list in a pdf document but do not see a way to attach it.

Will bose 901 speakers work with a AVR-4308CI


Yes they will, I have a set on a denon receiver amp ( not sur of the model # its in another town). The main thing for bose 901's is that the equlizer has to be connected somewhere beteen the preamp and the main amp, most higher power amps have a switch that opens a set of patch cord jacks that the Eq. can be connected thru. So you should verify this feature with any amp you chose. With out the Eq connected the 901's have no bass or highend sound.

I have harman kardon AVR 230 7.1, Can it run my new Bose 901 VI speakers, how i will connect the Bose EQ ( 901 VI EQ) to this AVR?


I have a setup similar to what I think you're trying to do and it works great!


You're in luck because you have a full complement of pre-outs. You'll need a separate amp for the 901's.


First some background.


The use of 901's Active EQ (or any external proxcessor) in any digital AV receiver setup for anything EXCEPT STEREO listening through the 901's alone requires you to have a separate amplifier for them and to avoid having to use a Tape Monitor which could introduce proprietary and potentially damaging Active Equalization back into anything in the AV Receiver with its conventional speakers.


In an AVR, if you activate any Tape Monitor circuit at all, you will kill any digital sources. That is a function of AV receivers in general, nothing to do with 901's. Your Pre-Outs get us around that possibility and limitation but it also means you need a moderately powerful amp for your 901's. I use a Carver MT-200.



Run it with the Active EQ between the receiver Front L and R Pre-Outputs ** and the 901's amp channels.


** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> new amplifier IN.


The AV Receiver can still drive the Center, Surrounds and the Sub(s) as it is designed. This is how mine is wired.


Then set the new amp's volume control (if it has one, mine doesn't) to something HIGH and leave it alone. Run through your speaker setup routines on the AVR. After levels and distances are set the AVR will be the boss of the 901's. With 901's don't even need subwoofers but they don't hurt. If you do have subs I recommend sharing the LFE with the 901's.


I've done this in my own setup once. Turn the 901's around so the rear faces point into the listening area. Crank up a movie like Master and Commander and when the waves are crashing or cannon are firing you WILL FEEL A BREEZE from them. Now THAT is multi-media! I advise having the 901's share LFE with any subwoofers you might have.

I cannot connect my bose 901 series v1 active equalizer to my denon av surround receiver avr-891


Short answer from personal experience.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

The reason: You can't use the Active EQ (or ANY processor) in a tape Monitor loop with anything but 2-channel stereo material. As soon as you activate the loop you lose digital sources.

Adding to YOUR particular problem is that the Denon doesn't have a volume-controlled pre-out to feed that amp. If you want to deal with controlling the separate amp volume manually you COULD connect the Active EQ between DVR Out and the 901 amp IN but you would have a stereo mixdown instead of true front channel from the speakers.

Bummer.

I have a Denon AVR 3805 receiver. It does not have a Main Amp in or a pre Amp out in the back. How do I properly hook up the Bose 901 equalizer to this receiver? I use the 901 speakers as surround...


By properly, you must mean WITH the Active EQ.

According to this picture, you're in luck BUT...

(Short answer from personal experience.)

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers. A good 100-wpc amp will do. (I like Carver)

Connect the Active EQ between the Front pre-outs and the amp input. Run speaker assignment, levels, etc and have fun.

Helpful Hint: If you don't have sufficient between-speaker room for proper reflection off the front wall you CAN turn the 901's around and you won't believe the amount of air these things push! I have actually felt it ten feet away after explosions or crashing ocean wave sounds. Now THAT is multi-media.

I have just bought a new bose 901 speaker system which included equalizer. I am not sure how to connect the equalizer to my receiver Denon 3808. I need help.


http://products.bose.com/pdf/customer_service/owners/901_guide.pdf

Be advised, this speaker system requires its own dedicated two channels of signal preamplification and power amplification and the required Active EQ is not to be used in the signal path of anything else. I have them as my Main Left and Right Speakers in a 7.1 set-up, but I'm using a 5-channel external Carver Power Amp to drive them, a sSb and the Rear Surrounds. The Active EQ is between the Receiver's Main L&R Preamp Outputs and the two Carver Amp channels that drive the 901's. Don't think you can just add the 901's into your living room and enjoy multichannel sound. Search around fixya, I have written extensively on this subject.

Connecting Bose 901 series iv to Harman Kardon AVR 254


Most HK av receivers have pre amp out,power amp in with metal jumpers connecting them for the main or front channels. that would be the best place to hook up the EQ on a AV receiver. If your receiver doesn't have pre out, power in jacks , you can use tape monitor .record out playback in. The tape monitor option is best for stereo use , as the active EQ will charge all speakers in tape mode, possibly damaging other speakers.I run my 901 s with a seperate pre-amp,power-amp hooked up to my Denon AV receiver that way i can run in surround w/standard speakers

Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the Tape Monitor with any type of stereo-only sound processor (non-Bose EQ, dbx expander, etc) and the various DSP options to spread 2-channel analog source material around the room. I have a whole stack of analog processors, tape and CD recorders slaved to my single Tape Monitor and then into a dbx400x Program Route Selector. It not only expands my Tape Monitor to handle nearly unlimited external devices but it makes routing for listening or recording easy with simple pushbuttons. But I digress...

The good news. I have a setup similar to what you want to do and it works great! With one caveat - My receiver actually has 5.1 analog Outputs (probably like yours) so I can drive up to 6 external amplifiers if I want to (I drive 4).

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels.

Is it possible to to have a home theatre with Denon AVR 3600


one option that may yield results, since the bose connection to equalizer is presently not possible is to set the speaker out put on the denon for 'small' on all but the front speakers.
and then set the delay for all speakers based on the distance to the amp.
this should result in better audio that that with the bose eq.
will work on the issue of using the eq. with the denon if you like. but, you will likely not improve on the sound with the denon set up correctly.
good luck
