    I'm new to these forums, and I'm trying to find a solution to my problem. Here goes nothing!

    I have an analogic console "Soundcraft Spirit M-12", 2 sound monitors "Tannoy Reveal 5a" and a 15" Macbook pro.

    With my mate we're trying to set up everything for the party, but when we came to the sound checking, we heard noise. I tested everything and found out that the noise is hearable only from either the laptop or the mini jack-ins.

    This Monday I'll go buy new mini jack-ins to test if the cables are the problem themselves,


    I'm fearing for the worst that the laptop might be the problem itself producing noise.

    Is there a way to get rid of the noise?

    Thanks kindly!

    You'd be better off using a "'real" audio interface plugged into the Mac's USB port. You are trying to drive a sound system from the Mac's headphone jack. Get a"real" interface and it will have balanced TRS or XLR outputs that plug straight into the mixer

    This is the cheapest decent interface you can get

    This one is a bit nicer

    Then buy a pair of TRS to XLR balanced cables to take the sound to the mixer.

    I see... I'll try this out. Fortunately, I have the M-Audio Fast Track Ultra 8R, which is an external USB sound card. I should use this one and link it to the monitors.

    Noise can also be the fault of a bad earth, or hum from devices such as transformers etc. in the vicinity of the Mac. The first thing I'd do is to move the power sources away from each other by plugging in to a different socket / outlet.
