Connect Bose 901 eq to Denon avr 2807

Have purchased a set of 901's that i want to connect to my Denon AVR 2807 7.1 reciever. It has a pre out for all speakers but does not have a main amp in connection.
Am sure there is a solution but can't find one.

Thanks

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 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. 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 L&R Pre Out >>> 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.

I have bose 901 series 2 speakers, marantz 8200 and 2 marantz ma700 monoblock amps how do i hook everything up? Thankd


Do you mean SR-8200? You can't omit the details of a model number if you want a good answer.

Assuming it is...

http://www.retrevo.com/support/Marantz-SR8200-Receivers-manual/id/511ci775/t/2/

Run the 901's with the Active EQ between the receiver Front L and R Pre-Outputs and the mono block amps, one chanel to each.

Pre Out Channel X >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> Monoblock IN

http://community.klipsch.com/forums/storage/74/1341919/200w%20mono%2005.jpg

I can't find a manual for the MA700. Set them up to a certain volume and then use the speaker setup routines of the SR to match everything up volume-wise. Control will be in the AVR.

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 Harmon Kardon AVR 247 and I want to connect with Bose 901 VI equalizer. No other speakers are connected, just the 901's. Where do I connect the wires from the equalizer to the AVR 247...


I have this exact setup. 901s are my Mains.

The AVR247 has PreOuts on all of the channels.. No jumper to remove either. Just get a power amp or two and place the 901 EQ between the AVR247 and the Power Amplifier.

I bet it would work if you listened to something 2-channel and analog. THAT is the limitation of anything that uses a proccessor (like the 901's) and modern AVR's.

Multichannel AVR's automatically disconnect digital inputs when a tape loop is activated.

Adding to YOUR particular problem is that the 3375 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 place some RCA Y-splitter cables where the Pre/Main jumers are and send a stereo mixdown instead of true front channel to the Active EQ and thence to a separate amp, but it's not true front channel. But you would have local control of the 901 volume after you calibrate them to match whatever other speakers you use.

When did they stop making AVR's with 7.1 pre-outs? My 9-year old Pioneer has them and I have 901's, 301's and a sub going.

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 am looking to upgrade my receiver to an audio video receiver that will hook up to a blue ray via HDMI. I want to use my 901's forthe front speakers. Can you recommend a mid priced (<$600) AVR that...


Good day,

Congrats on your new AV receiver. I own an awesome Yamaha mid-priced AV surround sound system with HDMI, BR disc player, and all that stuff. However, I'm old school and use my 901 Series Vs with a Yamaha RX-797 'two-channel' receiver. To get to the point, I have some bad news. Mid-priced (mp) AVRs, or any AVR for that matter, will not work with 901s because the active equalizer (EQ) requires either a 'tape monitor loop' or 'pre-out / main-in' connection to work properly. You've probably been told the 'why they won't work' by now and it is very true--I know from experience. Most of today's AVRs do not include a 'tape monitor loop' or 'pre-out/main-in connection for the EQ connection, thus, killing all hopes of using 901s. I truly love my 901 Series Vs (since 1985 and still kicking) and love true 'stereo' for playing my music. Again, 901s are useless with today's AVR equipment (as I know it). Just don't let your 901s collect dust--they are truly marvels!! Go with a set of good 'standard' speakers for the AVR system and buy yourself a decent stereo receiver or amp for the 901s--that's how I do it!! I've tried Onkyo, Rotel, Sansui, Poineer amps / receivers--all of them. I can tell you this--for the common, working man/woman, nothing, I mean nothing available can match-up with Bose 901s like a Yamaha RX-797 (200W)--not to mention the sound quality-wow!!! And this unit is very reasonably priced for such awesome performance and high quality build. Just know that all is not lost. You can still use your 901s--I cna't listen to music without mine.

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.

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
