Question about Bose Acoustimass 15 System

1 Answer

No output from Bose Lifestyle 12 system

Trying to help a friend fix his 1994 Bose Lifestyle 12 system.
I can hear the cd playing when I plug headset into the music center. radio works fine too. I hear a quick thump thump from the bass module and a short hiss from the cubes, upon power up. I checked the fuse and surveyed the bass module for obvious problems, and no bad smells. power seems ok.
Thanks in advance for any help.

Sounds like you have a problem in the circuits, which of course would take an experience technician to find and repair. But a 1994 electronic item has pretty much reached the end of its expected life cycle (sadly, compared to older equipment which is still working great). Basically, it sounds like the power amp circuit is shutting down a few seconds after startup. Might check to make sure no speakers or cables have shorts, which could activate a protection shutdown circuit. If any of the cubes don't hiss when you turn it on, that would be the first place to look for a problem.

The lifestyle system needs a power signal together with the audio signals, otherwise the unit/subwoofer will not come out of standby.
That system was build to run with the lifestyle player...not 100%sure you really want to go try and hack it.

Any readily available Stereo RCA to Mini cable. These cables are a in stock item at any electronics store.
Plug Mini side of cable into ipod headphone jack and the RCA side of the cable into any available input on the Bose system, match color for color, Red to right and White to left. Select that input on your Bose system and use the ipod as normal. This is the cost effective solution.
The better choice is to use a after market ipod dock system such as DLO http://www.dlo.com/products/homedoc_dx_Prod.tpl there are several levels to chose from all the way to HD outputs. These units can put your ipod display on your TV screen.

Bose 802 C series II to Yamaha rxv 459 Amp


Tech data sheet with diagrams:
http://www.bose.com/pdf/professional/802III_techdata.pdf

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.

The subwoofer sound is very low with the bose acousticmass 5 III


chewi5,

There is a saying in the audio industry I've come accustomed to hearing -
"No high's, no lows, it must be Bose" Anyway that is just a reference to the flat sounding nature of Bose in general and some people like the accuracy Bose is trying to deliver. I believe your problem is not related to this heavily opinionated statement. The fact that you have a very low sound coming from the sub is an indication that the RCA cables may be hooked up to an input rather than an output. I know this from my own experience and, if this is your problem you are in luck. Just find the proper output and the problem is fixed. The test tones and message also reinforce my main theory. However if this is not solved by my first suggestion you may have to start checking your audio cables for continuity. A bad ground (or even out of phase preamp signals) on an RCA cable can also produce similar symptoms. Let me know if none of this helped and I will try suggesting something more in depth & technical.

Simply doesn't work


The only contact with which I am familiar was made by a friend of mine who had received one of the original Bose receivers. Some six weeks later, she learned that they had become available with a CD player so she called Bose customer service and although she was not the original purchaser (her son had given it to her on a birthday), they immediately offered to accept the unit back and she paid only the difference between the two units.
I've heard other good reports about the company's attitude toward customers so I wouldn't hold back from calling them on their toll-free number that is probably in your literature.  
Good luck, and it would be helpful if you would post back your experience (good or bad) with them to help guide others.

Need a diagram to hook my Bose CinemaT speakers. When I hook it directly to the tv no problem but can't figure out how to hookup my reciever and CD player to work also? Help Please


You'd be better off hooking the speakers to the RECEIVER'S speaker outputs, THEN hooking your TV audio output to an unused receiver input, such as AUX. The signals from your receiver cannot reach the TV; thus your CD player and radio will not play through the speakers if the speakers are hooked to the TV. All receiver INPUTS are designed to accept the same signal level; thus, you can use any input for your TV audio, such as Aux, DVD, CD, etc. Just remember which input you're using for the TV audio, and everything should work fine. Almost all receivers have an AUX input; hopefully yours also has a dedicated CD input to avoid confusion. The you simply select the AUX input to hear your TV through the speakers.
