SOURCE: Trouble with rear speakers

This may be a software issue. If you only had two speakers before, the software will not use the rear speakers.
Go to Control Panel. Click on "Sound and Audio Devices". Under the Volume Tab, at the bottom, you will see a picture roughly representing the type of speakers.
Click on the Advanced button.
Click on the arrow in the pick box, and choose Surround Speakrs or the 5.1 Speakers.
Click Okay. Try the speakers again.

SOURCE: Re: Boston digital BA735. Hum with or without input signal.

Hmmm I just got the same problem. They worked fine on my old Dell desktop but when I plugged them in to my son's old Dell PC (maybe 1 year newer than my old one) they all hum like crazy - as you say even if it's just the power plugged in and nothing else. Yes it does have the original power supply. I get no music (but still it hums) from digital out/in but when I switch to analog out/in I hear the music and it still hums, plus the sound is distorted. Wierd.

SOURCE: I have the Boston Acoustics BA745 Computer Speaker

This could be because the speakers arn't getting a stereo signal, but first, double double TRIPLE check the wires are connected correctly. Iknow it sounds patronising but I don,t know if you are 8 or 80 years old and it's often best to go for the most obvious solution. afer making sure all connections are correct, have a look at the cable to the subwoofer - is there any damage to the cable or does the cable look like it may have been pulled - out from the sub or it's connection at the other end of the cable? Having eliminated the possibility of cable damage (it may be worth cheacking the cable to the pc) check various settings on your pc - are you getting sound from your other two speakers? if you are only getting sound from one of the left/right speakers and you're sure there's no physical failure with the speakers, then it's time to check your software. go to the little speaker ikon at the bottom right corner and right click. Select "Playback devices" select "speakers" and click "test" did you hear sound coming from the left speaker then the right? if yes then you definately have a problem with the sub. if no, click "properties" then "levels" and check the balance is set to the middle. If it is, then you should, again, suspect the speakers. Finally check the balance on your media player, if you use windows media player, go to "options" click "enhancements" then look for the balance control and make sure it's in the middle.
Finally, I would like to point-out that this particular speaker system is not known for having a loud subwoofer, put your ear against the hole in it and double check for anything happning inside (a crackling noise would indicate a danaged voice-coil.

Hope this helps.

Why does my MCS sub 10 not turn on?


Is that the right part number, MCS 10, and not MCS100?

The MCS systems use a basic sub which is matched to the satellites. There's very few controls other than level on the MCS100. So as long as the power light is illuminated the there's very little other than the volume control that could be set wrong on the sub. So what it comes down to is either

  1. a blown fuse (no power at all at the sub);
  2. a broken input (#1 cable, #2 sub input socket, #3 blown sub plate amp);
  3. incorrect connection at the receiver end or the wrong settings

As a quick test, unplug the sub cab from the amplifier/receiver end. Switch on the sub and turn the volume down all the way. Briefly put your finger across to short the RCA/phono tip and ring. The sub should make a buzzing sound. You now know that the sub is working and the cable appears to be okay

Switch off the sub and reconnect the phono/RCA to the sub out socket on the receiver. You now know it is connected correctly.

Go in to the receiver's menu and check the speaker settings. Is subwoofer present? Yes/No

Are the satellites all set to Small? (they should be with this system)

Are you playing a 5.1 source in DD or DTS to ensure that the sub gets a signal? Play a BD or DVD.

On the speaker balances, is the sub channel set to 0dB?

As long as all the above is set as listed, then the only things stopping the sub working would then be insufficient volume at the sub's Vol control (so increase it), or an intermittent cable connection (wiggle the cable), or a broken subwoofer out signal at the receiver.

Well I also have a S112PS AR Sub Woofer Problem...


Are you sure it is receiving an audio signal to make it wake up? You don't mention what's upstream in the audio chain.

To eliminate mis-settings or lack of sub-related signal upstream, plug an RCA cable from a CD player directly into it and start a CD that fades in slowly because you won't have any way to lower the volume except to pause the CD. If the sub works you'll hear a muffled version of the program.

Replacing sub speaker


I wouldn't try reinventing it by replacing the driver. Drivers and their enclosures are designed to work together. And this being a self-amplified subwoofer, there is one more piece that's electrically optimized to the rest. Don't mess with it.

Why don't you just set your receiver's individual relative speaker volume levels so the sub isn't weak by comparison to your other speakers? Weakness, as you call it, is relative.

Is your receiver properly channeling Low Frequencies to the sub? Experiment with the cutoff, too.

This problem doesn't require meatball surgery.

I Do Not Know How To Connect Boston Micromedia To My Computer


The Boston Micromedia speaker set comes with two speakers (right and left),a subwoofer, and a complete set of cables to connect everything up.

1.) Position the speakers. The two small speakers typically are spaced equal distance apart on a desk/table top to the benefit of the listener. The sub-woofer typically rests under the surface, on the floor for example.

.) Connect the cable sets to the back of the two small speakers along with the speaker feet.
Note: the small speaker with the volume control knob will have three cables coming from it. This will be the "right" speaker. The other speaker will have a single cable and will be the "left" speaker.

2.) The cable ends will be color coded to match the jackson the sub-woofer. Match up the color coded cables to the respective colors on the subwoofer as follows:

(a) White cable end (left speaker) to white jack on sub-woofer.
(b) Red cable end (right speaker) to red jack
(c) Purple cable end (input) to the purple jack
(d) Green cable end (computer out) to the computer's microphone output jack.

Note: if any of the cables are too short to reach their jacks for whatever reason, an extender cable with a female and male end can be purchased relatively inexpensively to make up the difference in distance.

3.) Power up the system (plug in power cables to the sub-woofer and wall), play some music, and adjust the sub-woofer sound (control knob) to suit listening pleasure.

A nice little set of speakers, I had mine for some years now and continue to enjoy them. Good luck!

Distortion


Your speakers are worn if you can try someone else speakers. Speakers tend to wear out with excessive use particularly when played once or twice loud its a try that wont hurt at least for peace of mind you may need not throw them out.
