Measure the resistance on the speaker cables and see if they are shorted (less than 4 ohms) somewhere. Swap around the speakers and amp ouputs to isolate what is the cause.

Speaker Err on Yamaha Home Theater Unit ???


I am assuming this is the message that shows up from your receivers front display panel? It could be the receiver is telling you that you may have the neg & pos. wires crossed and in the opposite position either in back of the receiver speaker posts, or in back of the speaker terminals themselves. My Yamaha receiver has this nice feature where it will tell you when the speakers are "Out Of Phase" which describes the problem I have described here.

Just go back and make sure your wires are hooked up correctly, and use tape and a Marker to label pos. and neg so they will be easier to hook up next time you have to move the system, or decide to change some aspect of your system. I would then take the time to label every wire that goes to each speaker that you plug into the back of your receiver. This a BIG time saver........

Lux Audio 5.1 home theater speaker & Yamaha HTR 5540 AMP


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.

Add more speaker to dvd player/s-air suround sond system


I have revisted this question and I *think* you are talking about a "speaker selector". A speaker selector is a unit that prevents an amp or receiver from going into safe mode or shutting down.

Help installing Yamaha home theatre system.


This is probably a setting problem on your remote-the unit will ony give full surround sound on Movies like dvd-on TV you may not get all speakers going as the cable does not provide signals to drive all speakers-check your manual and change to the appropriate setting-pro-logic is bad for this-will not give sound to all speakers unless the signal tells it to.
