I've got a Yamaha 5.1 surround receiver. I have 2 front speakers, 1 center speakers and a sub-woofer connected. When I watch dvd's, the sound quality is so fuzzy, I can't make out what people are saying. Any ideas?

The signal that comes from most tv's via the optical output is a stereo signal only. That is what your receiver is reading. You would have to manually set your receiver to decode the signal into surround,.
Follow these steps to connect a powered sub woofer to your receiver:
You typically have two options when connecting a powered sub woofer.
Input (1) on the rear of the sub woofer would be used when connecting
the sub woofer to the receiver using speaker wires. You would then
connect the main speakers to the opposite end, or output or the sub
woofer to the main speakers. Option (2) would be using RCA line level
output jacks, input (2) on the rear panel of the sub woofer directly to
the single sub woofer output on the back of an AV receiver.
Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer. surround sound unit sub woofer left front: positive (+) <-----to------------->(+) left speaker level in negative ( - )<- - -to- - - - - - ->( - ) left speaker level in
right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in
now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer. sub woofer front surround sound speaker left speaker level out (+)<-----to--------> (+) left front speaker left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker
right speaker level out (+)<-----to--------> (+) right front speaker right speaker level out( - ) <- - - to- - - ->( - ) right front speaker
Alright now that the wires are all over the place and plugged in turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone Mark Woodring
The connection on the receiver would be the sub woofer out. Not a sub woofer out LFE, a sub woofer out with speaker wire connection. From there you plug it in to the top section of the available terminals on the sub you are referring to (speaker level input). One in positive and the other in negative matching what you did on the receiver with correct ends. The speaker connections underneath the top connections is for additional speakers like surrounds to be able to be connected directly to the sub woofer speaker level out for sound. This of course would be for an older receiver connection. I do not think it is possible to convert this connection to an LFE and have it work properly. If the receiver does not have sub woofer speaker connection and only a RCA out then you can try to connect both rear speaker connections from the receiver to the speaker level inputs on the sub and then connect your rear speakers to the speaker level output on the sub to power them. This is an active sub woofer but for some reason they made it connect as if it was passive. I am not sure if this sub is designed for really low frequencies required for movie or if it is better for music.
the sub woofer speaker should be connected to the Center, the main speakers should be set to the front and the secondary ones in the rear....(front = main just in case surround is not on, center = is for that ump / boom sound, rear = that just pass you by (make you look behind yourself)
configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only. make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer. connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.
