    I run a pair of Tascam active monitors from my Mac using a Phonic Digitrack usb soundcard. I get a lot of buzzing from the left channel (and a small amount on the right) which is very noticeable and annoying when they are on but not being used. Is there anyway i can correct this. Monitors are about 4 years old.

    Thanks

    Is your Mac a laptop? Try unplugging it from the mains.

    Dosen't seem to make any difference. The speakers are plugged into the main any way.

    Okay, it must be coming from another source. I'd try unplugging stuff in succession and see if you can work out what's the root cause of it. Also try moving power supplies away from your audio rig.

    Unfortunately I'm not sure there's much you'll be able to do short of an isolator, which is rather overkill for something like this...

    As Dez suggested, you could use a ground loop isolator. I have active monitors that buzz slightly. I find that there is less buzzing when I set the gain on the speaker low but with the source level set high (but not clipped).

    I don't know what the quality of it will be like though. In Maplins they charge about £30 for a GLI.

    Edit: just done a google search and you can get them for a few quid.

    It may also be one of the compenents picking up mains from another source. It may also be worth trying different cables and also unplugging different parts to see what effect that has.
