How to connect bose 901 equalizer to yamaha rx-a1000

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.

Equalizers are generally connected via the tape in and out sockets.
However they do tend to affect surround settings, so you only be able to use it with the stereo mode activated.

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

You can do this however you will need a separate power amplifier.

See notes here: https://deercreekaudio.com/blogs-%26-updates/f/connecting-your-eq901-to-an-audio-video-receiver-avr

1. Connect the pre-out main left and right to the EQ901 inputs 1 and 2, and the EQ901 outputs 1 and 2 to the power amplifier inputs left and right
2. Connect your 901 speaker to the power amplifier outputs

The equalized signal will now play through the front left and right speaker outputs in the stereo and home theater modes.

Here are three options to connect your EQ901B or a BOSE 901® Equalizer to a typical Audio Video Receiver (AVR). See:

Option 1: Adding a Separate Power Amplifier - Best Option
This option requires that you add a separate power amplifier.
1) Connect the pre-out main left and right to the EQ901 inputs 1 and 2, and the EQ901 outputs 1 and 2 to the power amplifier inputs left and right
2) Connect your 901 speaker to the power amplifier outputs
3) The equalized signal will now play through the front left and right speaker outputs in the stereo and home theater modes.

Option 2: Setting up Your EQ901 B Using Zone 2 Loop
1) Connect Zone 2 pre-out to the EQ901 input
2) Connect the EQ901 output to any unused analog input
3) Select the Zone 2 source as any input (i.e. CD player)
4) Select the Zone 1 source to the input selected in step 2
The equalized signal will now play through the front speaker outputs in Stereo Mode Zone 1.

Option 3: Setting up the EQ901 B Using Only a Single Source
1) Use this option if you have only one source. This example uses a CD player
2) Connect the EQ901 B in between the CD player and any AVR input
3) This may require the 2V input mode on the EQ901B
The equalized signal will play only the single source (i.e. CD) when the input referenced in line 2 is chosen

Basically here are the connections you have to do:

In case you don't have tape recorder forget the "box" named tape recorder. Your RX-V992 is the box named receiver or preamplifier. You have to connect with RCA - RCA cables the tape out from the RV-X992 to Bose input, and the Bose output to tape in at RV-X992. With the setup connected like this whenever you choose from the RV-X "tape monitor" you will hear the sound equalized from Bose; if you disable the "tape monitor" switch you will hear without any equalization.

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.

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

Hi Mark, had a look for a manual on your Yamaha, but not got to one as yet. Does it have any RCA connections on the back marked as preout prein? best place to put the 901 EQ is in line with L and R front channels at this preout prein point.

Some amps DO NOT HAVE IT. If our does not, then you could connect it in the tape loop, tape out(rec) to input on the EQ. and the output of the EQ connected to tape in(play), but connected like this, the EQ would affect the tone across all channels(unless you are just running a stereo rig, then this way works great!!) Try this and you may just have solved you problem anyway.

how about you connect your pre-amp out to eq-in and eq-out to aux ?
