    Anyone have any recommendations on these?

    I notice when I have my laptop set up and charger plugged in it makes a buzzing sound out through my pa system.

    Ive heard of a specific charger you can buy to solve the problem.

    I dont want to spend too much on a charger for this laptop as im upgrading to a VAIO soon. So anyone know of any temporary fixes?

    I bought a Carpower ground loop isolator in Sounds Around on Capel st Dublin a few months back for around €18 and it works a treat.

    nope, if I understand you correctly here the one unit does everything. It goes between my audio interface and the mixing desk/pa - left/right - red/black in and out

    Im using A DJM 600 , Maya 44 USB soundcard.
    And running the mixer to my active top's via XLR cables.

    Would it help if i put one of these from each channel output of my soundcard going into the channel input on the mixer??

    I'm not familiar with those products so can't visualise how you'd hang it all together.

    i plug it into a extention lead first then plug the extention lead into the mains the worst than can happen is the extention lead fuse goes . i know its not the right way but it does for a quick fix
