Question about Sony Audio Players & Recorders

1 Answer

I bought a Nobsound NS-15G amplifier with the intention to connect it to a Sony Bravia TV and a Bose acoustimass 3 system with unpowered subwoofer. I used an RCA cable to connect the TV to the back of the amplifier (red on red, and black on white) and connected the subwoofer to the amplifier (red on red, black on black). The speakers are connected to the subwoofer as normal. When I switch the amplifier on the subwoofer makes a brief dark humming sound, which I though was promising but when I switch the TV on I only get sound from the TV speakers. How do I resolve this? Is this amplifier suitable for this purpose? I used to have a similar set up with the TV connected to AUX on the amplifier and that seems to work fine.

SOURCE: How to connect unpowered subwoofer to receiver with RCA sub out?

In order for this to work, you will need an external amplifier. Your receiver is set up to use a "powered" sub. With only speaker connections on the sub, it is a "passive" sub requiring a separate amp.

SOURCE: Hi. I got a Bose Acoustimass

Do you have any plan to use the Bose Acoustimass 20 sub/amp in it original form?
Please double check the pins count.
Popular Bose unit has 8,9 or 13 pins.
=====

A Bose third party vendor does sell a direct cable from the Bose Acoustimass 20 to two RCA and 1/8" stereo jack.
You can open the link HERE
Full site HERE
I'm sure you can find other cable vendor at a lower price.
======
I do not recommend you to open the Bose Acoustimass 20 and get the two set of wires out of the box.
It may cause damage to the casing.
======
On the DIN plug.
With notch / dimple facing the ground.
From let to right
1 = RED negative
2 = White negative
3 = RED positive
4 = White positive
5 center = un-use.

Please use an ohm meter to verify the resistance between1 to 4 and 2 to 4 before you start hooking up to the amp.

Please keep my posted on the project via email.

HOW CAN I CONECT THE BOSE TO MY YAMAHA AMP THE ONLY WAY TO CONECT THE BOSE IS TO BANANA INPUTS ON MY AMP AND THEY ARE FRONT SPEAKERS BUT THE AMP HAS A SUB OUTPUT


To enable the full potential of a SUB for Yamaha DSP A5 ,

you need to have

a separate amplifier for your Bose Acoustimass System.


The SUB out should be connected to an active subwoofer.

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..

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 use my ipod to play through my 12 year old Bose Acoustimass series 5 system


You don't connect an Ipod directly to any unpowered speakers since they need an amplifier between them and your source. Presumably, your speakers already have an amp source? Then what you need to know is how to connect the Ipod to the amp. Without specifics, I can only offer general advice. Get an adapter for the Ipod headphone it to make it compatible with either an RCA input or a headphone jack.

Please Help ....i have Bose Acoustimass 10, 5.1 system connected


Usually the LFE out is only a line out and is not amplified in any way, so first of all is your subwoofer self amplified or not? Cause if not, the LFE output won't be of much use to you. So if it's not self amplified you need an new amplifier to put between the receiver and the subwoofer. Any amp that supports RCA line-in input will do. Even a car stereo amplifier will work provided you can get a 12volt power supply to run it in the house. If the subwoofer is self amplified though, then all you need is to make an adapter cause none are readily available in stores to go from a RCA connector to 2 wires. You can buy a virgin RCA connector that you can wire yourself at The Source, Circuit City, or any electronics store you have locally, or if you have an old RCA to RCA wire you don't need anymore, you can just cut it in half, strip the 2 wires and you got you adapter right there.

You can buy it on ebay but it's cheaper just to make one. If you can solder, all you need is a female 15-pin d-type connector and a bunch of speaker wire. Here is a diagram of the connections.

How to start a Bose acoustimass 9 powered subwoofer


The Bose cube systems are SYTEMS for a very good reason. They're made for people who want good sound but don't want to manipulate the hardware much. The speakers and amps are designed for each other ONLY, not only electrically but through soundshaping to provide the smooth final result. The design is for you to feed the electronics a Line Level source and the magic and distribution happens internally. These are NOT mix 'n' match components. The special connectors are a clue. The 'different' amplifier will probably blow them up.
