    I've got Alesis m1 active mk2 monitors, and the hum on the is like a bee or sumit. it sounds like electrical hum, is this common to all active monitors, is there some way to rid myself of this hum? Could it be that i have eight plugs goin into 2 sockets?? Please help if u can, i'm probably being really dumb. Thanx

    Balnced cables

    Make sure you are using balanced cables... If you have xlr to 1/4" cables make sure the 1/4" end is TRS...
    GOOD LUCK!

    TRS is basically 1/4 connectors with 3 wires instead of 2. They look like Stereo connectors but in fact they are more like "compact XLRs"

    Be carefull there, you could be making a wiring disaster.

    A 1/4" TRS is a Tip, ring, sleeve. The tip is hot or +, the Ring is the cold or - and the sleeve is the ground/shield.

    The connection should probably be like this:

    Using a 2 wire with shield cable

    Tip to pin 2 (xlr)
    Ring to pin 3 (xlr)
    Sleeve to shield (xlr)

    Hope this helps.

    Lots of people remove the ground wire from all their audio connections, since all devices are grounded thru their power cord... You could try that.
