    Help!,
    finally got round to getting the temp room finished, speakers wired under carpet etc, however, have a slight problem with the front left speaker. All sound appears to be going through the sub for that speaker, the speaker works as ive plugged it into the right front ports and it was fine.

    The sub also makes a buzzing noise if the amp isnt powered up, is this related to the sound issue? or simply too close to something?

    Ive set the speakers up in the following way:

    Big cable from amp to sub, five speakers hooked up, dunno what to do with the lfe bit. Then the five speakers wired into the sub.

    Any help appreciated!
    Mike

    silly question, did you check the speaker cable for the left one?

    I found the mission speaker cable very finicky since it
    was sooo thin... very easy to break a strand or cut through.
    fine once you get it working though.

    re the noise from the sub, had exactly the same
    thing with mine... wait for it to go into power-saving
    mode... (amber instead of green light).

    also check what volume you have the bass set to...
    start at half, and work downwards till you are happy...
    it will hum if set too loud and nothing playing or not in low power mode.

    cheers for the post, im not using the mission cable, using microflat, the cable must be ok because the above test worked... stumped.

    will try the sub thing, it never used to hum though, seems to be only when the amp doesnt send a signal ie off

    didnt realise you could use different cable...
    thought it was special for the FS-2s (I digress).

    try getting a test tone out of the speaker...
    and check the levels for it.

    maybe the umbilcal cable isn't connected properly
    at the amp end?

    hi, tried both ends, seems to be happily secure, if i remove the front right no sound comes out, but when it tests front left all sound goes through the sub, ive tried changing the cross over freq but no good. How should i have set these up? should i use the sub out port on the amp and the sub port on the sub?

    cheers for helping

    yes, you can plug the sub connection in at the amp end,
    and into the sub phono on the subwoofer.

    think I had a similar problem with the humming and the
    lower power mode... doesn't work until you have everything
    connected properly at the sub end.

    as for the left speaker problem... this doesnt make any sense...
    think the power saving info above though implies there is a wire not connected properly or a cable is broken (ie... the circuit is broken somewhere so its not switching off).

    since the sub end of the umbilcal cord is hardwired and you know the speaker works, the only possible faults could be the left speaker cable from the sub or the connection on the amp...

    recheck the amp connections and +- ends for the left specifically.

    if no joy, cut a small cable (1m?) for the left speaker to the sub and see if that works... if no joy, maybe try connecting it as another speaker on the sub (the right for example)... this would then give you an idea where the fault is (amp?) or maybe a faulty umbilical cord.


    hope this helps.
