    Hi,

    Just a quick question:

    Hooking up my Mordaunt Short MS309 Sub to my Pioneer VSX-C501 receiver.

    The pioneer has a single phono line out for a sub, but the MS309 has L/R stereo line in's. How should I connect these?

    I know it may seem simple, but I don't want to do any damage!

    Thanks in advance,

    Mike.

    Just use a single phono to phono cable from the output to one of the input's.
    Or, you can get a phono splitter (Maplins or some such place) and then have the single out to both inputs. I believe this gives the sub a single about 3db higher than the single cable option and it also helps if your sub is set to Auto instead of continuesly On.

    Hope this helps!

    shodan is right. On my Paradigm subwoofer, splitting the signal to both inputs actually boosts the signal by 6 dB! Either way is correct, though.

    I have read that "splitting" may increase the output but it doesn't increase the headroom. So I suppose in theory you are reducing the dynamic range of your sub. Though I can't confirm this. Since it has only just occurred to me. :)

    Thanks all,

    I'll stick with a single in to left and see how she sounds.

    Cheers,

    Mike.

    If you have your sub in auto and find it sometimes sluggish to wake up fitting 2 cables will usually cure this. The esy and cheap way is to just leave the sub on all the time, as its a class D amp it doesnt draw much power aor generate much heat. ;)
