bose 901 series 1 equalizer manualHow you go about connecting the Bose 901-series equalizer to your stereo system varies slightly depending on whether you intend to use it in a two-speaker or surround sound setup. If you're using earlier 901 speakers, check for possible compatibility issues with the 901-series equalizer you're using before you begin. These devices might include tape decks and other equalization or signal processing devices. All jacks are located on the back of the Bose 901 equalizer. Connecting to a switched outlet ensures the equalizer is turned on or off automatically whenever the receiver or amplifier is turned on or off. Play some audio through the system and press the “Tape” or “Tape Monitor” button on your receiver. All sound should stop when this button is pressed. When it does, switch the “Monitor” button on the equalizer to the “Source” position. The audio should start playing again. If it doesn't, check your connections and try again. Consult the documentation that came with the receiver or amplifier for more information about which jacks to use when connecting an equalizer. The 901 Series VI active equalizer must not be used with 901 Series I, II, III or IV speakers. All rights reserved. Bose, Acoustimass, Lifestyle, Personal and Wave are registered trademarks of Bose Corporation. For additional help in solving problems, contact Bose customer service.The use of 901 Series VI speakers without the 901 Series VI active equalizer will result in improper per- formance. The use of graphic or parametric equalizers, instead of the Bose 901 equalizer, will result in unsatisfactory performance. Follow these steps, in the order below, to install your 901 Series VI speaker system. 1. Choose the best locations and support for the 901 speakers (page 6). Pedestal (A) and ceiling mount. See the inside back cover for phone numbers.It is important to use the right thickness of speaker wire. For distances of up to 30 feet (9 m), 18 gauge (.075 mm ) 2-conductor wire works well.http://rcot.org/userfiles/bosch-maxx-manual-pdf.xml

For distances greater than 30 feet (9 m), refer to the wire recommendations chart on page 18. Your choice depends on the type of receiver you own and whether you plan to use the system primarily for stereo or for home theater enjoyment.Refer to the address information inside the back cover of this guide.Connect right channel to right channel and left channel to left channel. To use an external signal processor, or to add a graphic equalizer, contact Bose for more information. Refer to the inside back cover of this guide. How you set the equal- izer depends on how it is connected to your receiver. Press your receiver TAPE MONITOR button to the IN or MONITOR position. This switches the equalizer into the system. Use the tone controls on your receiver only after the MID-TREBLE and MID-BASS sliders have been set according to the procedures below. These controls let you make adjustments to compensate for the effects of speaker location, room acoustics, and program quality. Then check all the connections between the speakers, receiver, and active equalizer. Or call Bose directly (see inside back cover for phone numbers).

Reviewed Nov 21st, 2018 by Artfrobadoo My buddy has a pair of supposedly original 901s which I have suspicions of being fakes. The wood does not match. There is no labeling. The terminals are crude. He thinks they are the cats meow. So I searched craigslist and I found a pair of 901s for 200 dollars. Then the guy throws in a beautiful working Kenwood KA 7300 amp. I like my Bose 301's better then these 901 VI. Perhaps it's the amp I have the associated speakers to what.

I took advantage of the Bose Trade-in program some years ago when they still offered it.

I cannot find the Series III Service Manual. Thanks To be use for PA system or Karaoke. Any suggestion for an appropriate mixer. I'm looking for resources to help me troubleshoot and repair the equalizer. I don't have much experience, but I would like to learn, and this seems like a fun project. If anyone is willing to help break things down as simple as is convenient, or could help guide me in this process, I would be very grateful. We all have to start somewhere. I refurbished the speakers myself, and would like to say I did the same to the equalizer. Due to purchasing from a second hand store and not really knowing enough about them I consequently now own two right hand speakers. Not sure how this will affect the speakers. While it might well be quite possible to fix, I would be more interested in feeding the speakers from another signal source. The cable from the preamp connects to the speakers via a five-pin 180 degrees DIN plug, and so I think it should be quite possible to connect to some other signal source, the same way I have used a pair of Philips MFB speakers. Am I right or am I right. Anyone have any experience of the 901p active speakers. Or of other Bose Lifestyle 20 substitutes for them? No need to attend a live concert anymore.

Across the whole spectrum of human hearing, highs and especially lows, are clearly heard through these speakers. Nothing I say about them matters very much, because they must be heard to be believed. Reviewed in the United States on September 27, 2016 Lot of debate on these. Everyone's taste are different and usage is different as well.https://www.fvsspa.com/images/bose-901-manual.pdf My perspective is that they are good pa, background speakers for casual listening while doing chores and are infact sweet sounding, meaning they don't kill your ears with brightness or detail certain speakers have(which maybe more fault of horrible recordings that better systems can reveal) so you don't get much listener fatigue from the highs (as there is no tweeter and cuts off around 13k)',, Definitely has a house sound, But critically listening, sound rather monotone and does not have transparency,sound muffled, and rather veiled. Then, when they heard side by side with even the cheapest speakers I had, castle, monitor audio, kef, etc.they couldn't believe how muffled it sounded by comparison and the shock in the faces told the story. These are not overpriced like the lifestyle systems in terms of material cost to build them. Also, Some people bash it because of paper drivers but paper actually sounds among the mist natural over metal cones, Kevlar, if properly engineered. Used by audio note, scan speak, etc. For me, they. Are not for critical use. They maunely serve as a tv stand and will probably be used in the garage. However, music and taste is subjective so if it sounds good to you, stick to it. Some audiophile speakers also sound horrible and can be more annoying vid listener fatigue.

Kployhar 5.0 out of 5 stars That was when I was stationed in Germany in the Army the first time. I could not afford these back then. I bought some Klipsch KG4's which I still have (blown horns). So instead of new, I found a guy who was going back to the states and bought his 901 Series Ones from him, and fell in love.ballestermultiservicios.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626bcb634c991---case-580-user-manual.pdf At the time I was powering them with an Onkyo and Technic's amps I had bridges for a total of over 500 watts per channel continuous power. They handled it beautifully and would cause the CQ to come to my room almost daily and tell me to turn it down. I used that pair of speakers until 1995 when I got divorced and I sold the whole system to a friend who still rocks it to this day. Same 901's that he refuses to sell back to me. On to this purchase. I decided to buy a new pair, and wanted the black ones to replace a pair of Series V in walnut. So they arrived pretty fast. I paid for one day shipping, but they came in about three over the weekend. Who can complain about that. I unpacked them, spend some time with the tulip stands from the old set and wiring, and then I put the power to them. I run these with an old Bose 1801 amp, a Yamaha Pre-amp and the Bose EQ. Hey, they brought a new crispness to the music I enjoy. I pushed everything through them. Rock-n-roll, Country, Jazz, and Classical horns, and everything sounds wonderful. You will read a lot of reviews from folks who do not like these speakers, and you will also talk to people who like Ford, Chevy, and Dodge trucks. Everyone swears their's is the best. All I can tell you is these sound wonderful if you pay special attention to speaker placement, wiring, and equalizer set-up. I am very pleased with the sound, the product and the shipping. For all the people who are not fans of the 901's, probably did not set them up right. My eighteen year old son swore up and down that the new stuff was better. A steak is still a steak, and modern tech cannot improve that. He is now a 901 believer, and not a convert yet but in college he cannot have my old set. I will say to everyone, it is important to have good equipment to drive these and to get them most out of them. Do not hook other speakers up to the equalized system, and pay attention to room placement and you should get great sound from them and tremendous bass. You too could be a convert. Also I would like to add, your wife will hate the way you have to set these up, and will offer several suggestions as to what you should do with your new speakers, but you can follow my lead and leave with your 901's and never look back. I thought it was cheap way to get out. As a disabled Veteran, it is difficult for me to carry these heavy items to my vehicle, and in my area you cannot even find this product locally. It is nice to have a department store on the web. Thanks again Amazon. So here is my final thought. Buy a set of 901's, kick your complaining wife to the curb, get a hot little girlfriend, and turn up the tunes. Addio!Please try again later. Please try again later.

My surround sound system has a full set of different speakers being used with my Onkyo 7.2 amplifier. My Onkyo receiver has a Zone 2 and a Zone 3 Pre-Amp outputs. I am also using my Zone 3 Pre-amp outputs for my Bose 901 and headphones. I love both the surround sound setup and my Bose 901 Stereo setup. I use my Bose 901 for listening to Stereo Jazz, Acoustical Music, Classical Music, etc. They do not do well with hard Rock or music with heavy bass., that was prior to my discovery below. All I can say now is, WOW!!! Of course, what sounds good to me may not sound the same to you.

Please try again later. Craig 4.0 out of 5 stars Have been listening to my set, bought new in 2013, for three years and always enjoy the experience (despite the laughs you get from others.). Here's the bottom line for me: they succeed or fail based upon room positioning. You need to get them 8 or more feet apart, equally and at least 18 inches from an unencumbered wall, AND, most importantly, make sure there is unimpaired space on that wall between the two speakers. Once so arranged, the famous 3D soundstage appears and performers appear shockingly realistic. It also helps dramatically if you raise them high enough so that they resonate at your seated ear height. Yes, it is also true that they do not have the crispness of some modern designs (say, with AMT drivers) and are somewhat less precise than tower speakers because you hear, mostly reflected sound. If you reflect that sound against a very soft surface (drapes) the result will fail. Speculate that one reason for the extreme reviews these speakers generate has to do with 1) the necessity for correct positioning and 2) the need for a preamp feed to the equalizer. Enough power is also required -- would suggest 100 watts RMS or more. Pundits ridicule the equalizer but I suggest this: would you rather have an EQ'd, coherent sound or a crossover one that always suffers from tonal compromise. They do sound coherent.Please try again later. Please try again later. The striking cobra 5.0 out of 5 stars I'm a music writer and have listened to ten's of thousands of records from country to rock to blues to jazz. It's become fashionable lately for so-called audiophiles to bash 901's and even to bash Dr. Bose. The guy was a genius, an MIT engineer and professor who won every award out there for sound. 901's have been used in studios for decades for playback, in auditoriums, in concert halls. No other speaker out there works as well, if they are used correctly. That means correct placement, moving them around and making sure the music is reflected properly. In a room full of people they can't be beat. Don't listen to the people bashing these, most of them have never owned a pair.Please try again later. Please try again later. Adrian G Wilkins 1.0 out of 5 stars They require use of an equalizer that will only work with certain amplifiers. The Bose recommended list of amplifiers only includes discontinued models. I have called them and they tried to be helpful but could not do much. Because I took too long trying to get them to work right I can now not return them to the vendor Wizard-Electroland who was basically useless in trying to help me with my problem. Clearly some of this is my fault for taking too long but overall a very bad experience.Please try again later. Please try again later. The EQ901 Elite is our flagship equalizer building on our EQ901B series with lower distortion, greater dynamic range and higher fidelity made possible audiophile grade digital signal processors, DACs and analog signal stages. When you power the EQ901 Elite on and off be sure that associated equipment is off first. Connect power to the EQ901 Elite before turning associated equipment on. Specifically: Normal mode is the most neutral, Enhanced mode provides a richer sound with more treble and bass, Warm mode adds midrange with slight treble reduction, and Low frequency reduction mode is intended to control bass in smaller rooms or on boomy recordings. The EQ901 Eite is shipped with the analog input level set to 2 Vrms. Warranty does not cover failure of the product due to incorrect connection or installation, improper or undocumented use, unauthorized servicing, modification or alteration of the unit in any way, or any usage outside of that recommended in this manual. The customer provides return shipping to Deer Creek Audio. Deer Creek Audio is an Authorized miniDSP dealer. Bose is known only using paper cone drivers pushed into unusually small boxes, never publishing frequency response specs, and suing Consumer Reports for giving them a bad review. Even though paper is a good material to use for speaker drivers, and plenty of audiophile companies don't publish specs, the perception is that Bose is overpriced junk. If you have a satellite speakers or a subwoofer, you can thank Bose for popularizing that form factor. If you enjoy a high quality factory car stereo, you can thank Bose for that as well. They were installing EQ'ed Class D active speaker modules in the doors of Cadillac's back in 1984. Bose was doing research using Dummy heads and figuring out head related transfer functions in the 70's that laid the ground work for headphone and VR breakthroughs that are happening now. As for the argument that their gear is overpriced, I've heard much worse for much more. Profits from Bose smart manufacturing, not corner cutting, has funded research that shaped much of today's the audio landscape. This is the speaker that back in 1968 proved commercial viability of omnidirectional, dipole, and all sorts of bizarre dispersion patterns. This pair was made back in 1987 when Bose speakers were still made in America. The design has not changed since then, and honestly it's almost longer in the tooth than Klipsch Heritage speakers.The drivers also have the ugly looking tinsel leads on the front, but on the plus side the plastic baskets are branded three times along with the dust cap. These drivers are 1 ohm each, and are ganged up in such a way internally to produce an 8ohm load.The rear grills are a molded metal mesh and the clip to cover the back drivers. The rear grill also works to cut the treble response from the rear drivers. If you try running these speakers without the rear grills expect shrillness on a scale that should not exist in the natural world.The port tube design is something I've never seen duplicated, it makes for a very deep tuning without much physical volume. The downside is that these ports can put a candle out from 6 feet away and are audible at full chuff.It's a pretty stout box if you account for all of the holes in it.The idea is that you hook up your wire and thread it through the speaker stands. Then, unless you want to put wood screws into your speakers to attach the stands, you are in for a chore. The dance of flipping the speaker while trying to hold the stand onto the bottom is a contortion that only the 901 owners can understand.This iconic design is really beautiful, if not the most functional. The wire is supposed to run through the top and out of the bottom, but there is no notch for it to slide under on the bottom. Instead the wire just kind of get smashed and the stand becomes slightly unbalanced.The blue line is for the default Bass EQ, the red line is for the secondary bass setting. Yes, that is a shit ton of treble boost, as well as a healthy chunk of bass boost.Choose up to 15dB variation in the treble tone, and 10dB to the mid-bass. I took over the living room and pushed my main speakers into the corner. I ended up at 16 inches from the rear wall and pushed them a bit wider than my main speakers to give them as much room as possible to operate. Now in a perfect world these would have an uninterrupted wall behind them and closer to corners, but I don't have that option so the right channel is stuck on the hallway side. Originally the 901's were to be setup mostly at ear level when seated. The setup for the past 30 years has been tied to these short stands, or hung from the ceiling far off axis. There is even a recommendation for matching pairs of floor and ceiling 901's in some manuals, something I'm sure a few die hards have tried. I'll break it down the performance of the speaker into a few standard categories and how they perform in comparison to other options out there. After initial placement I never once felt like I needed to move the speakers to get more out of them. Imaging is huge and involved, but it is hard at least in my setup to place or pick out specific elements of the music. There is no denying the 901's ability to make you hear all of the music, but because the image is such a blur I don't seem to notice it as much as directional speakers, it instead you get the feeling of it. In contrast, Linkwitz dipole speakers create a soup of sound spread around the room, where the 901's transform the walls into massive speakers.These are some of the loudest speakers I've used in the 200Hz-10kHz range. Setup outside I was able to blast 112dB of non distorted music out of the back of the speakers measured from 10 feet away. The front was limited to about 98dB, which is still pretty damn loud for outdoors. I can see why there is a version of these speakers for PA use. When you start to get above 95dB the bass response falls off as the little drivers can't play deep bass at high volumes. This can also lead to them falling apart before 95dB on complicated tracks that are also bass heavy. For instance most Chemical brothers tracks are limited to about 85dB just because the full range drivers just can't do everything at once.If you sit and listen critically you will be met with harsh treble and bloated bass. Adjusting the EQ to fix these problems will leave the speakers sounding dull as it turns down all of the treble when the worst problems in the cone breakup range above 5k. Bass response is harder to nail down, it's hard to get away from the muddy bass, and honestly the Bass EQ options seem limited to either bloated bass or no bass.Some simple instrumental tracks sound good, but anything with female vocals or cymbals should be avoided. These speakers can be used in a party scenario, and will impress most drunk people with the quantity of sound they produce.My neighbors had to deal with 95dB sine sweeps for 3 hours straight, and then pink noise for another hour. I think you will find the results are totally worth it though.This the most quiet axis of the speaker, so it's not as important as other measurements, but this is definitely not a good start. We are seeing bass response down into the 30's and a jagged sloping response to the treble and a massive 7kHz peak. The jagged response is probably due to baffle reflections, and comb filtering from the 9 drivers all doing the same thing.It's damn near impossible to make out what is happening here, but generally the response gets much louder as you move around the back of the speaker.On the bottom we have the front power response, this is an average of 0-60 degrees. On the top we are looking at the rear power response, an average from 120-180 degrees. Yes, the rear is about 10dB louder, than the front.It's an average of all of the off axis measurements, or the total power response of the speakers, and it's flat. Normally a power response would be tilted to show a roll off of the treble, but it's hard to say that it's wrong given the strange dispersion pattern. Maybe this was the intended goal of the speaker, or maybe it's just a coincidence.This measurement was taken slightly above the axis of the speaker to better represent the suggested listening height. The red measurement is with the speaker 12 inches from the back wall, and the blue one is 18 inches. These are very similar, with the 12 inch being a little nicer. Also, note that the 7k peak is not hidden by the boundary, rear speaker interaction, or even being off axis vertically.I continued on like this until, finally I ended up cutting everything a little. While it definitely sounds better, the correction is far from perfect due to the inherent irregularity of the speakers response.He went through the trouble of designing excellent five inch whizzer-less full range drivers and stuffed 9 of them in a clever box, While it has plenty of flaws, I respect it's performance, blasting off faces and painting walls with sound in a way that no other speaker can.First priority is to get a subwoofer, crossing over to a sub as high as 90Hz can really clean up the sound of the speakers, and will give even more headroom. The second priority would be to add a dome tweeter to the speaker. A stand alone enclosure that sits on top and crosses over to the 901's around 3k with something like a minidsp would fix all of the cone breakup and much of the comb filtering issues. Doing all of this should still leave most of the imaging tricks intact and while it does add considerable cost, there are worse things to do with your money.Micca COVO-S Review! The Dayton B652-AIR is reviewed for great justice. Other than using a green sharpie to get better CD sound, or that guy that calls you on the phone and osmotically makes your system sound better, no greater myth exists in audio today than that of the Bose 901 speakers. Much like Bigfoot, have you even seen a pair of Bose 901 speakers or, better yet, heard them? My Fiat 500 Sport has a Bose sound system, and yes, it possesses admirable bass extension (so there!) and a wide stereo image from the driver’s seat. I also experienced Bose on a recent trip home from Spain, where I sampled the new Burmester sound system in the latest Porsche 911 Cabriolet, and Porsche was kind enough to fly me home first class. The latter experience came with a pair of Bose Noise Canceling headphones (another product I’d never actually used, but about which I heard plenty of scuttlebutt). I’m thinking of investing in a pair before my next European trip. So that’s two strikes in Bose’s favor. My last memory of the speakers harkens back to a jazz club in my hometown of Milwaukee that actually had the speakers installed into the ceiling by their pedestal bases and powered by a Marantz 4300 quad receiver. Another area venue had their ceiling-mounted 901s powered by a large stack of McIntosh gear. Both systems were pleasant. Not to be outdone, another bar owner installed Magnepan MGIIs from the ceiling, which, coincidentally, ended up being destroyed by a ruckus started by the Milwaukee Rugby Club after a hearty victory. And so it goes. Sure, I love my Maggie 1.7s, but they don’t produce a lot of bass, either, and really need a lot of juice to give their best performance. And don’t even get me started on single-driver Lowthers. Been there, done that, too. Are you thinking mythbusting? Me too. I bought a random pair of 901s via the Web for retail price. I initially tried to contact Bose to see if we could get a review pair, but no one at the PR department would return my call. Hence, there will be less historical data accompanying the review, which is unfortunate, as the speaker is now on its sixth iteration of development and changed somewhat since its introduction in 1968. Unless we get a phone call, this will remain an unresolved question. If I must have a pair of 901s, I can special order them or go directly to the Web site. I do the latter, and about 90 seconds after getting to the home page, a pair of walnut 901s with pedestal bases is on its way. Six days later, the 901s arrive on my doorstep, safe and sound. Next, the listening begins. Will the speakers fall off their pedestals. Stay tuned for Part Two. An Eames lounge chair and an old copy Playboy is all that’s required for the full-on Austin Powers effect. Groovy, baby! However, using them with the metal bases requires wood screws. While the holes are predrilled, you probably won’t utilize them more than a couple times without causing permanent damage to the speaker base.
