How do I connect my Bose 901 series iv speakers and equalizer to crown c2000 amplifier. I need your help.

You may connect an additional amplifier to the Rec Out or Line Out from your existing receiver.
Please note the Bose 901 equalizer can be used to connect to one amplifier only.

Do let me know if you have any further questions.

The short answer is no. The more useful answer is:

The EQ is designed so that the 901s reproduce the correct sound levels throughout hte audio spectrum. Given the size of the individual speakers (approx 4") and the lack of bottom end response for speakers that small, some tricks are used between the EQ and teh cabinet design to allow for total response from 20Hz to 20,000Hz. That being said, the power to drive the speakers comes from the amp not the EQ. The output of the EQ is not sufficient to drive speakers.

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.

I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

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 various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want 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 it with the Active EQ between the receiver Front L&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.

Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

If you purchase the Bose Active Equalizer you will in fact need a receiver or amplifier. Personally I would just skip the Bose Active Equalizer and go right for a more high end receiver. It will do the curve response that you require for these speakers without any need for pre-amplification. If you read around it looks like this is what most people are doing with the speakers, and the ones that have purchased the Equalizer are not very happy with the results they are getting.

The 901's are great speakers and with a matching quality receiver or amp you will have fantastic results.

Thank so much, please let me know if you need further clarification, but you definitely do need a receiver with this unit.

Thanks
