Harmon kardon avr 146 with Bose 901 EQ VI

I realize this receiver is not one of Bose's approved receivers for the Bose 901 Series VI speakers. But there has to be a way to make the equalizer work. I've scoured this site but cannot find anything specific to the AVR 146. The speakers work with the receiver but sound really really hollow - no eq obviously. If you have any suggestions that don't require an external add-on I'm all ears. Otherwise, I'll have to just switch out the receiver. Thank you all in advance.

Bose is a pain in the back like Apple. Everything they make is proprietary or it won\'t work. The 901 series is one of them.

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.
Contact me at danmc@uwyo.edu and I'll forward the pdf.

SOURCE: I have harman kardon 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.

Recently I bought a Harman Kardon HK 3770 Stereo receiver. My question is " can I use a Bose 901 Series VI speaker with this receiver?, since I plan to buy a 901 S VI speaker.. The receiver has no tape...


From the description of the Harmon Kardon, it sounds like you should be able to use the speakers, but you will not be able to use the active equalizer. The equalizer is designed to be cabled into the tape monitoring loop and allows you to listen to the equalized signal coming back into the receiver. Attach the +/- speaker wires to the right and left channel speaker connectors on your receiver.

AVR 1600 receiver won't connect to bose series III EQ


You mean BOSE 901 Series III Active Equalizer; and HARMAN KARDON AVR1600 right?

Sure it will. It goes in a Tape Loop such as Tape Out/In or Video 1 Out/In. But it won't work for anything except analog stereo sound sources as all digital audio is not available to the RECORD OUT jacks when the Tape or Video 1 is activated. AND 901 Active EQ is intended solely for 901's, not any other speaker system

The HK has no Line Level volume-controlled Pre-Outs so you're out of luck if you want the 901's to take part in a multichannel setup, which would require a separate power amp to drive them anyway.

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.

Hi There, I have a Marantz SR7005 Receiver and Bose 901 Series VI speakers with the Bose equalizer. I'm struggling to figure out the best way to connect the Bose equalizer/speakers to the SR7005. ...


It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

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 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.

Bose 901 series speakers to Bose 901 Equalizer


There is no direct connection between the 901's and their Active Equalizer. It is designed to be inserted between the source and the DEDICATED amplifier driving the speakers. Typically, this would be in a Tape Monitor loop on a receiver.

Tape Rec/Out to EQ In; EQ Out to Tape Play/In on the receiver. If you have a tape deck(s), it(they) would go into the back of the Bose EQ as if it was the receiver and you would use the Tape and 1/2 buttons for selection.

Or,if you have access to any other point that doesn't use the Tape Monitor, like a Pre Out/Main In jumper set, place the Equalizer there. That way it's always in front of the speakers and doesn't take up the Tape Mon.

Flip in the Tape Monitor and leave it on or the speakers will not receive the essential ACTIVE Equalization they require for proper frequency response. DO NOT place non-901's onto any amp using the Active EQ.

Like any speakers, the 901's will attach to the speaker terminals in the conventional manner.

Connect Bose 901 VI EQ to a Harmon Kardon AVR 247 Amp


Similar problem...I came up with a solution with help from Onyko. For my receiver, at least, the bottom line was that the output from the equalizer MUST go to 'Receiver, Tape In'! Since that is the ONLY input source from the equalizer, you must combine elsewhere. Part of my setup included the Radio Shack Audio/Video Selector box which costs $21.99...you might not need it, but in my case, I couldn't plug all components into the back of the receiver and have them go through the equalizer.

Since I have a satellite receiver, DVD player and TV, that I want to route through the equalizer, here is the way mine is set up and working:

Satellite receiver and DVD player out to Radio Shack audio/video selector

Audio/video selector out to VCR in.

VCR video directly to TV

VCR audio red/white (audio) out to equalizer

Equalizer out to Receiver Tape IN (Receiver Out not used)

Hope this (or a variation of it) helps.
