Is there a filter I can purchase remove the hissing and humming noise I get from plugging my laptop into my amp?
Cheers Lads

Also check your connectors from the pc to the amp....

Prices start from MUCH lower than the above website, Chris may have some in too.

Cheers lads. Will look out for one today.

Mine was under a tenner from a local electronics shop, not sure about hiss, but it will definitely remove mains hum.

Thanks again, I have found one for £7.99 fromk the shop with the old holiday camp name!!!!!

Plugged my new laptop in last night, and didn't have a spare isolator on me, so ended up with back up laptop which doesn't need one, so am off tomorrow, when I meet C.S to buy a few more.

Went down to the shop and picked one up, plugged it in, brill, no humming noise at all.
Cheers

Has anyone tried putting the isolator inbetween the mixer out and amp rather than between the line in and laptop ?

The noise in this case is down to the laptops "earth"...

Some power supplies for lappys are compleately isolated from the mains in side. however the other type actually use the earth as te ground for the DC line.

A quick test for this is to unplug the laptops psu from the mains.

I have this, but only on systems of 2k +.

Hope this helps !
