SOURCE: bose 901 v1 adding a amplifier

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.

SOURCE: Problem connecting Onkyo Amplifier to Bose Accoustimass speaker system

This is probably correct as modern equipment uses electronic volume controls rather than potential dividers the range is normally biased towards the bottom end so there is lots of the range that is quiet and a smaller part that is loud.

Unless you find that at the top of the volume range the system does not seem to be loud then it is probably correct. It is not uncommon for modern equipment to clip at 80 / 90% of the volume range. Where as old style equipment with volume pots used to clip at arround 30% of the volume range as it gave the apperance there was loads of extra volume available. In fact all that happened if you turned it up louder was it clipped more and more.

Andrew

SOURCE: Hi. I would like to connect a Bose controller

Tech data sheet with diagrams:

In a nutshell, the controller would go between any preamp Stereo OUTput and a dedicated amplifier INPUT. You really don't have much choice in the matter. The 802's and their controller are part of an inseperable system.

The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.


I don't have any data on your mixer/amp but if you can't insert the conroller logically between the mixer and its amps then you'll have to get separate dedicated amplification for the 802's, with the controller between the mixer and that amp.

The other question is are you using a standard bose input or another component to feed the amp? If you can vary the input to a lower level that may solve the problem. More likely though the unit has a internal component such as a capacitor or a IC that is no longer working. Have the unit serviced at bose or a trusted local repairman. Good luck. Dan

My Bose SA3 2 channel amp keeps blowing when I raise the volume with non-bose speakers, why is this happening?


Could be the impedence of the speakers that you're connecting. The bose amp was designed to drive 8 ohm speakers.

I have a bose acoustomas system. It does not have HDMI inputs on the bose amp which denies me hooking a blu ray dvd to the system to access sound for the speakers thru the amp. I want to have dvd and hdmi...


Simple.Depending on the number of HD gadgets you have,you need either 2 or 4 channel HDMI converter.Connect the HDMI output to your tv and connect other equipments to the various HDMI,VGA,component and composite inputs,including your Bose System.

Sa3 bose not sound from boselink but external input yes


It depends on the Bose system you connected with the amp and the type of Bose remote you are using?Does the indicator LED at the rear of the amplifier stay solid green when you press the ON button on the remote?If not,check that your room code setting on the remote correspond with the micro switches setting at the rear of your amplifier.

Bose sa3 amp, blew a fuse in it, replaced it and now it won't power up. Nice little amp, would like to find out how to test out what is wrong and fix it


If you can,check with your multimeter to see if the two voltage rectifiers are good.If they are OK,you may need to replace the 2 audio amplifiers.This will require proper tools and good experience.

I don't know the impedance of these speakers but the Bose SA3 amplifier is 100watts per channel.A higher wattage speaker may damage the audio amplifiers.

I have a Bose Wave, Multi CD changer and wish to output my TV audio to it. Bose reps say all I have to do is connect Red & white audio cables to the AUX input on the CD changer and to the TV's Red...


The only other solution for this would be to connect the red and white RCAs directly to the source that you're trying to hear. (i.e. cable box, dvd player etc.) I have seen a convertor that will go from digital coax to RCA, but I'm not sure how reliable it would be. Plus a good one would be very expensive for what you're trying to do. You could also get an RCA switcher. Connect all or your components (cable box, dvd etc) to the switcher, and an RCA output to the Wave system.

If it's an original 321 system (series 1) then it has an audio output on the back. (via RCA jacks) You would still need an amp or receiver to connect the speakers to.. (unless they're powered speakers)
If it's a 321 series II or 321 series III- it does not have an audio output.
If the system has a DVD tray right in the middle of the media center, then it's a series 1.
Otherwise, you'd have to get a 1/8 splitter to come from your Mac's headphone output. (still- you will need an amp/receiver or powered speakers to have both 'rooms' playing the same thing from your computer)

Bose 802 C series II to Yamaha rxv 459 Amp

In a nutshell, the controller would go between a preamp Stereo OUTput and a dedicated amplifier INPUT. You can't use Bose 901 or 802 EQ in a multichannel setup without separate amps for the Bose speakers.

The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.

In a vanilla stereo configuration you would just put the controller/EQ into a Tape Monitor loop but multichannel sound and digital sources won't work that way.

You should be able to draw off the (assumed) Front L&R channel preamp signal from the MD/CD-R or DVD-R Audio Out (REC) jacks (*). Run that to the Preamp In (or whatever it's labeled on the Bose EQ/Controller). DO NOT run a return RCA pair back to the Receiver as Bose-processed signals will not play well with non-Bose speakers. (*) Run the Output of the Bose EQ/Controller to a powerful separate amp for the Bose 802/901's. I use two channels on a Carver multichannel AV-406 amp but a stand-alone Carver MT-200T also works well. A good clean 100 watts/channel should suffice at home.

* If possible, choose the recorder loop you are NOT using for something else. If you're using the MD/CD-R or DVD-R Audio OUT for a recording device just get some RCA splitters to share the Stereo signal between the Bose and the device at the same time. However, once you select monitoring of that recorder two things will likely happen - 1) you'll lose the Bose and anything digital in the receiver will be disabled.

It's the nature of the digital beast that analog monitoring gets in the way of DSP.

Of course, if anyone who reads this has a receiver with individual analog Audio Outputs for the various 5.1 channels (as I do), the solution would be to draw off the Front L&R channels to the Bose EQ and downstream amplifier and the rest would be the same but without Recorder Loop limitations.

Connect Bose 901 VI EQ to a Harmon Kardon AVR 247 Amp


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.
