Re: cannot hook eq to my receiver

The speakers will not sound right. You dont have two tape monitors on this receiver? You can simply use the tape otput to the EQ input, and then the Tape monitor input to the EQ output leads. Good Luck

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...

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

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.

If your system is equipped with a tape monitor loop, you can switch the EQ out of the circuit by disengaging the tape monitor switch. If the EQ is connected to the pre-out / main-in jumper, you would have to defeat the EQ before you hook up a conventional speaker. I don't believe the EQ has a defeat switch - you'd have to rig a bypass.

Once defeated, if you have a system equipped with a Speaker A / Speaker B selector, the smaller speakers could hook up to the second system. If that's not possible, speaker switches are available for reasonable money. It is very important, though, that the 901 EQ i defeated when using conventional loudspeakers.

I have a set of 901 IV with no equializer, I am

As far as I know, any equalizer will work. There is a guy on here that might know more about them, but I never had the Bose equalizer and I have Bose speakers for 35 years. The guy at the electronic store back then sold us a little equalizer at first, we graduated from that a long time ago, and now on the 3rd or 4th one. No problem, works great, sounds better than ever. Hope this helps.

Bose 901 speaker with eq

You want them to be your Main Front speakers, right? The news is not good.

There will be some limitations because you can't extract 'processed' L-R from this receiver. The following will give you good stereo and Front L-R from the 901's but it won't allow central volume control or send them any of the DSP effects you may select. Sorry. If it had a Front L-R Pre-Out you'd be good to go for all functions and listening modes.

You'll need a separate stereo amplifier WITH ITS OWN VOLUME CONTROL for the 901's to accommodate the need for the Active EQ. Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. I'm using only 100W for mine and it has plenty of steam for the 901's.

With this receiver we have to cheat to get the Front L-R signal out to the 901's (but it's unprocessed and at a steady volume level)...

For connection I would run a pair of RCA cables from the VCR/DVR Audio Out L-R OUT jacks (*) to the Active EQ's Line IN; then the EQ's Line OUT to a separate amp's Line IN. Attach the 901's to the new amp.

* You'll lose the ability to use these jacks for anything else, but few of us use them anyway. DO NOT select this function for monitoring or you lose all audio in the Onkyo.

Can I hookup a Bose 901 EQ to my receiver and amp?

Your instincts are correct. In fact, the only way the 901's can live in an A/V system is with dedicated amplification.

Put that old amp back to work.

This is exactly how mine are connected.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ's Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

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.

How to hook up bose series 2 eq to onkyo tx sr 875 receiver.?

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! I see on the SR875 there are Pre Audio OUTS. This is easy.

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 >>> 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.

Connecting Bose 901 series iv to Harman Kardon AVR 254

Most HK av receivers have pre amp out,power amp in with metal jumpers connecting them for the main or front channels. that would be the best place to hook up the EQ on a AV receiver. If your receiver doesn't have pre out, power in jacks , you can use tape monitor .record out playback in. The tape monitor option is best for stereo use , as the active EQ will charge all speakers in tape mode, possibly damaging other speakers.I run my 901 s with a seperate pre-amp,power-amp hooked up to my Denon AV receiver that way i can run in surround w/standard speakers

No. Active Equalization is required for the 901's and not to be used with any non-901 speakers.
