It turns out that I really don't need the left rear output. That's because I don't need the center speaker, so I wired the left rear speaker to the center output. I'm not using the system as 5.1 - it's being used as a PA system, and that's why I can get away with this arrangement.
Still would be nice to have the schematic though in case another output goes bad.

Very week sound


Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.

you need to run the left speaker output from the amp to the left speaker input on the Bose, the right speaker output on the amp to the right speaker input on the Bose, the center channel output on the amp(assuming it has one), to the center channel input on the Bose...then the right output on the Bose , to the right Speaker..the Left output on the Bose to the left speaker...and finally the center channel output on the Bose to the center speaker

Altec Lansing VS3251 rear left channel not working


Sounds like you "blew" the left channel. Make sure your connections are good, and all positives and negatives hooked up the way they are meant to be. If it still does not work, take it to be repaired. Call around first, with the AND serial number. Get repair estimates, ask about the "bench charge"

I have just bought a new bose 901 speaker system which included equalizer. I am not sure how to connect the equalizer to my receiver Denon 3808. I need help.


http://products.bose.com/pdf/customer_service/owners/901_guide.pdf

Be advised, this speaker system requires its own dedicated two channels of signal preamplification and power amplification and the required Active EQ is not to be used in the signal path of anything else. I have them as my Main Left and Right Speakers in a 7.1 set-up, but I'm using a 5-channel external Carver Power Amp to drive them, a sSb and the Rear Surrounds. The Active EQ is between the Receiver's Main L&R Preamp Outputs and the two Carver Amp channels that drive the 901's. Don't think you can just add the 901's into your living room and enjoy multichannel sound. Search around fixya, I have written extensively on this subject.

Rear speakers dont seem to be loud. The front speakers are projecting most of the sound. How do I get the rear speakers to project more sound?


Your settings in the receiver are not set up properly.
You need to adjust the volume output through the rear channels in your receiver.  Review you manual for set up. The issue is in the receiver, not your speakers most likely

I have connected my philips 5.1 channel dvd player properly with Altec Lancing VS3251 speaker 5.1.There is audio output from the front speakers but there is no audio output from the rear left/right and...


to get 5.1 you need to have an optical/co-axal/hdmi input in to the speakers to get 5.1 and then the dvd player must have one of them as an out put

hope that helped

Can you hook Logictech x-540 to a tv for surround sound


this is a direct connect meaning you have to have a connection for every channel. So if your tv has outputs for 5.1 channels then yes you can but most tv's dont output this just stereo, meaning you will only get sound out of your left and right channel because most likely your tv might have the red and white outputs for right and left.
There is no dolby processor in the speaker system to take a 2 channel input and make it into 5.1. This is usually done through your sound card or your receiver. Some receivers will have preouts for this. i dont know if you have an amplifier hooked up to the tv if so you can see if your receiver has those pre-out connections.
i hope this helps clarify the situation.

Left Channel Not Working.


Has it ever worked?

Try this - connect one pair of its speaker wires at a time and test it. Watch the polarity.

• Make sure all cube speaker arrays are connected to the proper terminals according to their
position in your room.
• Check to be sure all wires are connected to your surround receiver with the proper polarity
(+ to + and – to – wires). Incorrect wiring can result in a total loss of module output.
• Correct any wiring problems before you plug in your receiver and turn it on.

How do you know the receiver's Left channel isn't the fault? Sounds like a source issue.

I have no amp for jamo 1060 sub


Dual Voice-Coil
The unique Dual Voice-Coil design allows both left and right channel sound from just one speaker. Simply hook up both the left and the right channels to the special terminals on the speaker. Hook up one channel only, if the speaker is to be used in a conventional stereo set-up.
I found this on jamo site hope that will help you
