Default Legacy Bose Lifestyle 12 with LG 55LM4600 HDTV

Greetings,

Brand new member here. I recently pulled an old Bose Lifestyle12 system (circa 1996) out of storage, now that I have a suitable space to use it in. My TV is an LG 55LM4600, and my cable box is a Cisco 8742HDC provided by my service provider Brighthouse Networks.

I used the Bose with an old analog JVC TV for years with no issues. Now that I have the new LG HDTV, I'm trying to figure out if I can get it working with the Bose (with something close to surround sound). The only audio out on the TV is digital optical. Of course there is no optical on the Bose of any sort. However, the Cisco cable box has both digital and analog (red/white) RCA out. I use the HDMI connection from the Cisco to the TV for video (and internal TV speakers if I choose). I ran RCA cables from the Cisco's audio out to the Bose music center video. This works - sort of. I get stereo sound only. The FL, center, FR, and acoustimass bass function well, but I can't get anything out of the two rear speakers. The Bose system is wired correctly, in that CD output can go to the rear speakers if I choose. My guess is that the Cisco cable box is doing something to prevent rear sound from being sent to the Bose music center, and ultimately to the rear speakers.

I've researched this for hours, studying digital to analog cables, converters, etc. and have found a lot of conflicting information. Given the info above, can you guys think of way to get TV sound to all 5 of those little Bose cube speakers? I really don't want to buy a whole new surround sound system if I can get some mileage out of this one.

I appreciate any advice. Thanks in advance.

If you are runnimg red and white rca cables to the bose then all you can get is stereo - you are not sending surround sound. That is what red/white rca cables are - 2 ch stereo only.

But, when I used my old analog JVC TV, and ran the audio red/white from it to the Bose, the music center put out sound on all the speakers by default. I'm trying to get something similar now. My guess is the signal being sent with today's DD5.1 by the cable company is somewhat different than what I was getting 15 years ago, but it was Dolby Surround Sound back then too (pro-logic maybe?). The real question (I think) is the Cisco cable box the culprit or is the Bose music center? I think one or the other just cant handle the decoding properly and just outputing stereo.

Again, the system output Dolby Surround Sound just fine with the red/white cables 15 years ago. The ONLY connections for TV audio were from the JVC's red/white audio out to the Bose music center. I dont know the difference of what was being transmitted/converted back then vs. what is being transmitted/converted today, but I'm pretty sure nothing was digital back then.

Dolby surround was only 2ch not 5.1 it was faux surround. You can probably find a setting somewhere on your bose unit to emulate it but in all honesty it isn't worth it as bose sound is utter crap to begin with and a decades old one even more crap. You are batter off with tv speakers

I've read the manual many times, and the only thing I can find is that the videostage (music center) can send anything to the 5 speakers. Perhaps that is the faux surround you refer to. However, it aint working anymore.

Not sure I agree that Bose is crap, but it certainly is overpriced.

When I get a chance, I'm going to wheel that old JVC (yes it still works) into the living room and run the cable to it (with and without the Cisco), run the audio out the back of the JVC to the Bose, and see what happens. If all speakers work when direct connected to the cable, then the Cisco is the culprit. If not, then the signal coming down the cable is something the Bose just cant handle like it use to.

I appreciate your insights - thanks.

Although this is not what the OP wants to hear, it is, unfortunately the truth.

I dont mind hearing that at all. I'm just trying to get this old system to perform the way it use to - that's all. I realize there are way better options available today, but just dont want to spend the coin if I can get my legacy system to "integrate" with the newer technology. There are all kinds of cables/converters, etc. - I'm just looking for a way to make it work.

In the meantime, the Bose puts out FL,FR,center and bass that it fairly impressive - and much better than the internal TV speakers.

Default UPDATE from OP

UPDATE:

Hooked up the old JVC TV yesterday. Ran cable straight from wall to TV, then ran red/white RCA audio outs from TV to the Bose music center. Worked like a champ, rear speakers and all.

Next, ran cable from wall to the Cisco cable box, ran composite yellow from Cisco to JVC TV for video, and audio outs from Cisco to the Bose. No rear speaker sound in this setup - other speakers fine.

Obviously, it's getting lost in the Cisco, which is kind of what I expected.

I'm looking at the device from Amazon from ViewHD(VHD-ADAC digital-analog-adapter-decoder) to see if I can get sound to all speakers with the LG HDTV (not the old JVC TV), faux surround is OK. I can connect the device either from the HDTV or the Cisco cable box, as both have digital audio outs. Do you think this device will let sound get to the rear speakers, or is it just going to output what I have right now - which is FL,center,FR, and acoustimass subwoofer?

Thanks in advance.

P.S. Forum would not allow posting of the amazon URL, as I dont have enough posts. It's $44.95 and a amazon search of VHD-ADAC should bring it up first.

They were being a bit hard on you about "faux" surround, probably because you mentioned Bose in your original post. There are people who have a tremendous hate for anything Bose. I say if Bose sounds good to you, it's your ears.

As far as "faux" surround goes, that is an incorrect characterization. Pro-Logic surround from 2 channel stereo is surround not "faux" surround. It was the first surround ever used and multichannel 5.1 came later which is an improved surround version both because it is digital and has individual channels for each speaker. If interested here is more detail: Let’s Talk Surround

Good call rbinck , I meant faux as in not 5.1 or discrete. I remember the initial prologic days. Faux in the sense that they are expanding and matrixing 2ch into multiples.

Well they do have those processors that add hall, theater and other echo or reverb that are rightly called faux. Prologic is not anything like that. Matrixed channels are discrete just not separate. If the encoders and decoders are really high quality then the result can be just about as good as discrete audio. That's why when he was hooked up to a monaural source the rear speakers disappeared. Prologic got a bad name because of cheap decoders that caused pops and other annoying sounds. I used to have a Lifestyle 12 and they had one of the better decoders that was available. Just the speakers are lacking, but some people love the Bose sound.

Do you think the converter/adapter device I mentioned above in post #8 will solve my problem? As I mentioned, I'm just trying to get things to work they did 15 years ago, even thought that may not be optimal.

Trying the URL again, if I have enough posts

if you read the product info desc. states:
Decode and Convert Dolby Digital and DTS 5.1CH to 2CH Stereo Outputs

Size: 5.1CH to 2CH Audio Decoder

this is a step down converter it will take 5.1 output down to 2 channel.

Yes, I read that. But you haven't really answered my question. Is that "stepped down" 2 channel output any different than what I had 15 years ago, as described in several posts above? It was 2 channel also (apparently Dolby Pro Logic), but the Bose was able to put out sound to all 5 speakers plus the subwoofer. As I mentioned, I got it working correctly on the old JVC TV - only when I introduced the Cisco cable box (which I really need) did the rear sound disappear. If the Cisco is permanently "sanitizing" the signal, I may be screwed. I'm hoping that is only true for the stereo audio outs on the Cisco itself.

But if it were to carry ALL the data out the HDMI to the LG HDTV instead, then out the optical audio out to this converter device at Amazon, and then down convert it to 2 channel stereo, what will the Bose do with it?

Hope this clarifies my problem a little - I appreciate your thoughts.

That is going to be your best bet for attaching the TV to your Bose. You will still wind up with Prologic level surround. Not as good a solution to buying a whole new 5.1 setup, but it will get you to where you were before. Getting a converter that will handle 5.1 digital is important as some of the converters won't handle the 5.1 input.
