Bose acoustimass 3 system connect to TV without receiver

I have an old bose acoustimass 3 system that I would like to connect to a tv. How do I go about this without investing in a bulky AV receiver. Will a simple amplifier work? I was looking at a nobsound amp but not sure I can hook up the sub woofer to this.

There are a number of different models. Assuming you don't have a Powered version of the speakers (You'll know you do if you have to plug the subwoofer into AC power)
For the Unpowered systems, the subwoofer plugs into the Speaker R and L outputs of a receiver or an amplifier, so you will have to provide amplification. The satellites plug into the subwoofer and are NOT intended for direct connection to an amplifier.

You should be able to use whatever amplifier has audio inputs from your TV, and regular speaker wire connections out.

take it back for refund or exchange without delay. Too many times, there are cases of faulty factory assembly. Most likely a poorly connected wire inside sub, which fell off after a few booms.

SOURCE: Anyway to bypass my Bose Amplifier

not too sure what you are trying to do but just buy a aftermarket deck..for example for 100 bucks jvc has a nice deck with remote that plays mp3 and even has a jack right on the faceplate for a mp3 player.then throw your subs in the trunk hook up the amp and bingo banging beat.if u have the aruroa with the battery under the back seat its even easier

SOURCE: bose acoustimass 25 subwoofer has no power

Honestly speaking you should probably not work on this unit yourself: "There are no user serviceable parts inside"

Even if you are an accomplished Electrical Engineer Bose will not provide the required schematics to troubleshoot and repair this unit.

Are you still undaunted . . . then if the case is the original LS-25 series, there is a hidden catch at the end of the cover furthest from the input connectors that needs to be rotated (until a plastic tab is sticking out), which you can do with a flat bladed screw driver, and you also need to remove a few screws from the bay where all of the connectors reside. Remove the two knobs from the side of the cover. Then hit the case with your fist at the far end (plastic tab) and the cover should then pop off. You may have to hit it hard, with an upward motion.

Note there is not going to be much you can do to fix this beyond replacing the fuse. (Note that the fuse may be soldered in.) The bass amplifier is op-amp based with discrete class G output stage and the twiddler amps are monolithics with discrete class G circuitry shared between several channels.

The power transformer has a thermal fuse in it as well which is not replaceable. If you play the unit loudly for long periods of time and it is not adequately ventilated it is possible for the thermal fuse to open - if this is the case you will definitely need to send it in for service.

When plugged in there are hazardous voltages present on the top PC board where the power connector is located, whether or not the unit is turned on.

Power switching is via a triac controlled by whichever front end you have CD-5? 12V should be present on the mini plug (tip I think, but might be ring) when the music center is on.

There is also offset detection circuitry that will latch the unit off should any output have more than a volt or so of offset.

How do i hook up bose accustimass speaker to my radio?


Acoustimass speakers need to be driven by a Hi-Fi amp/receiver or AV receiver. So the thing that's driving them needs to be an amplifier.

Unless your radio is also an amplifier then the radio and the Bose speakers are not directly compatible. There's no suitable output on the radio that generates the correct signal in sufficient power.

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

Have this Bose system connected to my Yamaha a/v receiver


If you have it literally conencted the way you say not much good will happen.

The speaker OUTPUTs for the Yamaha feed the INPUTS on the Acoustimass Module then the satellites branch out of the Acoustimass Module's OUTPUTs.

Acoustimass module
Bose® recommends putting your Acoustimass module at the same end of the room as the
television monitor. To prevent interference, keep the module at least 2 feet (.6 m) from the
television.
• You may hide the Acoustimass module behind or under furniture, but do not block the
opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
corner.
• Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the
cable connection end, remove the cover by gently pulling it away

Move the sub closer to a wall or corner to increase the bass.

This is a SYSTEM and as such is not designed to be pieced out or separated. I don't recommend that you try it that way. I doubt it will improve the sound.

I have a Lifestyle 35 and want to replace head unit with a 5.1 receiver. The Bose subwoofer model LSPS uses a network type cable connector on the sub side and a male din plug on the head unit side of...


The entire 5.1 amplification system, in the Bose Lifestyle 35, is actually part of the Bose Acoustimass (subwoofer) module. The RJ-45 (network type) connector passes a low-voltage signal from the console to the Acoustimass module. If you were to hack the connection, and plug the speaker outputs of a 5.1 receiver to the RJ-45 socket on the Acoustimass module, you would blow the amplifier.

If you are really itching to replace the Bose Lifestyle 35 console with a regular 5.1 receiver, I strongly suggest you sell your Bose system, and purchase a Bose speaker system, such as the Acoustimass 10 Home Theater Speaker System, which is made for use with a standard 5.1 surround sound receiver.

How do I connect my Acoustimass® 5 Series III Stereo Speaker System to my Onkyo SR506 av receiver?


Well, first of all this speaker system is designed to give you a subwoofer where you do not have a sub-woofer output on your receiver/amp. However, that is not the case with the Onkyo. The way I would set it up (only because of the speakers you have) according to the Acoustimass Manual. You take the left and Right "Speaker" outputs to the Left and Right input on the Acoustimass and the speakers crossover does the rest. The Onkyo is designed to have a powered subwoofer so in this format you would just tell the receiver to turn off the sub channel which would tell the Onkyo to send the low end to LR. That should do it.

Can i connect my bose 5.1 speaker system to my pc directly without using a separate stereo receiver? my pc has a 5.1 hifi with optical sound card and an 800w psu.


no it can not. the sound card in your computer has no power behind it, only a signal. the acoustimass needs power from an amp. you can connect your computer to a home theater reciever and get what you are trying to do, with a simple 3.5 to rca cable.

Sony STR-DG810 w/ Bose Acoustimass 10


Try this:
Go into the menu settings by pressing "Receiver" --> "6-Video" --> "HDMI Audio" select "Amp," not "Amp+TV"
Yeah, it makes total sense to have a very important audio setting in the video menu.
