Using Bose 901 Equalizer on Yamaha HTR-5840 Reciever

The Bose 901 speakers require the use of a specific equalizer that is designed to optimize their performance. If you have a Bose 901 equalizer, you will need to connect it to your Lafayette 3500 receiver in order to properly use the speakers.
Here are the general steps for connecting the Bose 901 equalizer to your Lafayette 3500 receiver:

1. First, ensure that the power is turned off on both the receiver and the equalizer.
2. Locate the preamp output jacks on your Lafayette 3500 receiver. These will typically be labeled as "pre out" or "line out".
3. Connect a pair of RCA cables from the preamp output jacks on your receiver to the input jacks on your Bose 901 equalizer. These jacks are typically labeled as "preamp in" or "line in".
4. Next, connect another pair of RCA cables from the output jacks on your Bose 901 equalizer to the main amplifier input jacks on your receiver. These jacks are typically labeled as "main in".
5. Turn on your receiver and equalizer, and ensure that the volume levels are set to a low level before playing any music.
6. Set the Bose 901 equalizer to the "On" position, and adjust the various equalizer controls to your preferred settings.
7. Finally, play some music and adjust the volume levels as needed. You should notice a significant improvement in the sound quality of your Bose 901 speakers with the equalizer properly connected.

Note: It's important to use the Bose 901 equalizer specifically designed for the speakers. Using a different equalizer or not using any equalizer at all may result in poor sound quality or damage to the speakers.

Exchange it for one that has tape in end out jacks on it,

1

Examine your receiver to be sure it has a tape monitor loop. Receivers with a tape monitor loop will have a button or switch on the front for "Tape Monitor," and have two sets of RCA connections on the back, one labelled "Tape In," and the other "Tape Out."

2

Take the two cables that are provided with the 901 speakers and insert one end of the first cable into the "Amplifier Input" jacks of the equalizer. Connect the red connector to the R input and the other connector to the L input. Connect the other end of this cable into the "Tape Out" connections on the receiver. Again, hook red to R and the other to L.

3

Connect the second cable between the "Amplifier Output" jacks of the 901 receiver and the "Tape In" connections on the receiver. Follow the guidelines in Step 2 for R and L connections.

4

Plug the 901 equalizer into a 120-volt electrical outlet. Your 901 equalizer is now installed.

I don't know why the comment from Yamaha about Tape Monitor killing digital inputs is relevant.

According to the manal I downloaded, THIS stereo receiver doesn't have digital inputs.

As to using 901's and 301's...

You will need a separate Power Amp for either the 901's or the 301's. Sorry, but you can't share the amp with the Active-Equalized signal and non-901's.

I use 901's and 301's in MY 7.1 rig with a separate amp for the 901 and NOT using a Tape Monitor, but a preamp out feed for the front channels.

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.

The Bose EQ connects to the tape out and tape in on the amplifier or reciever. If you were using these for a tape deck, you will then have to connect the tape deck to the tape in and out on the Bose EQ.

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.

how do I hook up the bose 901 EQ to a yamaha DSP3090??

1-record out from receiver to to equalizer in.
2-equalizer out to tape pb in receiver.
