Hi all, What I am about to ask will probably explain my lack of contribution on this site thus far (I haven't got a clue what I'm doing!): I am now the owner of the Teac Legacy 800 Home Theatre kit - bought from Richer Sounds - and I have had no success in getting the sub-woofer to output any kind of signal/tone. The only cable in the entire kit which appeared to be used to connect the sub to the amp is a sinle connection at both ends; the amp has one connection ok but the sub has two connections? Richer Sounds' assistant said as long as I connected the amp out to the sub in (either L or R - didn't matter) it should work. The test tone puts out a sound on all the other 5 speakers but is silent when the sub is meant to be active. I've set the sub as 'on' using the amp menus and am testing in 5.1 surround. I have checked the power switch by the mains feed is on and that the 3 way switch (off/auto/on) is also set to 'on'. There is another switch which changes the (degrees?) from 0 to 180 - I've tried it on both settings but with no success at all. The kit overall seems decent but the instructions are poor, particularly for a novice, and the speaker cables provided do not indicate which feed is + and which is -, so after I get the sub working I have to uproot the speaker cables and trace from end to end - not a pleasant task, I think. Apologies for the length of this post but I wanted to ensure I got as much information pertinent to my problem in there as possible. I'd be really grateful if anyone can shed some light on this. Thanks, ted.
