Im trying to connect a bsr xr eq to my avr687 denon receiver

The problem with equalizers is they can mess with things like Dolby signals on AV units. The best way yo avoid this is to connect tape decks or CD players to the EQ and then connect the EQ to the tape in socket of the AV unit.

Well the basic connection of the speakers would be the same as another stereo speaker pair. Wire the left and right speakers to the L/R Front Surround speakers on the Denon.

With the 901's I am assuming that there is an external equalizer supplied by Bose. Typically this EQ is installed in a tape loop on the receiver/amp so that it is ahead of the power amplifier that drives the speakers. This EQ needs to be there to attempt to get reasonable frequency response from a speaker that has only 4" drivers. I'm not sure I see any reasonable way to make the EQ work with the Denon AV receiver. You'd likely be better off using the Bose speakers in a dedicated 2-channel stereo and getting a set of speakers for the AV usage.

Seems like it should be , audio out to the eq. Then out of the eq to your sound source, ( speakers )

what you have is a tuner. it is just a receiver, not one with an amp included. you will need a amp to get this to operate. the tuner is one of the best they made. it is a keeper. i would get a quality amp and use it. this is what was refered to in the past as seperates. purchase seperate tuner, amp, and may an eq.

What are you doing with the extra amp? You can use it as a preamp by connecting a 5 or 5+2 channel amp to the Pre Out section witch RCA cables. If you just want to adjust the EQ of the right & left, put the EQ between the two. If you want to EQ all channels, you'll need 3 equalizers. Isn't 120 watts per channel enough? If you don't have it already, download the owners manual from Denon Support Site.

from cd analog output to input at the yamaha, then from output to dvd/cable/ cinch input at the Denon.

Treat each EQ (or any processor) as as Tape Deck and place it on its own Tape loop on the Denon. Tape deck(s) can attach to external processors because they always have tape loops to replace the one they use.

Rule of Thumb: OUT's go to IN's.

You can have as many processors as you want. I have five.

You can serialize processors if they would logically be used together or you could get a dbx-200 or dbx-400 Program Route Selector which provides connections and switching facilities for 3 processors and 3 tape decks but uses only one tape loop on the receiver.

Individual processors can be engaged or disabled, and the whole mess can be placed in the record OR the playback end of the chain - all via front panel switches. Very versatile.

Connect through the tape monitor jacks and if a tape deck is used connect it to the eq! Check your owners manual if you still have it or download one.

There's good news and bad news. The bad news is that a multichannel receiver with Bose 901's will only sound right in STEREO on stereo analog material. For one thing, the other speakers around the room are not designed to recieve its Active Equalization and for another, if you engage your Tape Monitor you will not be able to play digital sources. Tape Monitor is for analog stereo material only and on my receiver it disables any digital inputs.

The good news. I have a setup similar to what I think you're trying 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 the dbx and BSR in tandem with each through the tape monitor loop on the receiver but be advised you can only use them on analog source stero material. However, you can still employ the various DSP options to spread the sound around the room.

At my PC workstation across the room I have a stack of analog processors and sources including dbx 3bx-ds, dbx 120x-ds, BSR Spatial Enhancer, BBE 462 Sonic Maximizer, SS-525x EQ, Carver C-9, dbx-224x, JVC cassette deck, Dual 1249 Turntable running through a Garrard MRM-101 Preamp, Pioneer PDR-509 CD Recorder and the Media Center PC stereo analog channels all running through a dbx 400x Program Route Selector (a godsend) which is attached to my ONE TAPE MONITOR on my Pioneer VSX-36TX Receiver. Of course, I have some of my analog processors running in tandem, too, since the 224x only has three processor and three tape loops.

For listening/recording anything 2-channel analog I engage the stack through the Tape Monitor. For everything else I turn the Tape Monitor off. The nice thing about the stack being separate is that I can doodle with recording and use headphones while the TV/DVD/Blu-Ray do something else.

If the amp has PreIn PreOut connections, then thats the best way to go. Home theatre amps however, have 5 InOuts, and this makes it hard. You can use the tape loop. Hook up the rec out on amp to inputs on EQ, and output of EQ to tape in an amp, then engage the tape monitor function whilst ensuring that the rec selector has the source you wish to use the EQ for.
