    it wasn’t me either – but it was a simple accident. there is a extra menu admins/mods get and its the first menu option and easy to click by mistake – especially if someone is using a laptop with a touchpad or another mobile device where its easy to click things without meaning to do so.

    I’ve just spent nearly hours sorting out a noise/grounding issue (was testing to see if I could record sound / stream from another computer). Tried every combination of sound cards, USB leads/hubs etc – and I haven’t got the kit to make up balanced cables and not all my kit is balanced anyway….turns out that the mains PSU is the source of it but the machine I was going to use for this is a old laptop with a fucked battery so it has to be plugged in.

    Managed to solve it by using a even older machine to deal with the incoming audio, but it turns out that newer laptop PSU’s with a 3 pin mains connector send all manner of crap and noise down the mains earth and because of safety rules this ends up on the audio signal earth as they are normally connected together…

    Yep I’ve had this exact problem before when doing the sound for a show at the film and comic con for my mate at earls court last year.

    He was advertising his pc game he was making at the time and using a laptop hooked upto a big monitor and speakers, but the battery lasted about 20-30 mins tops so we had to have it plugged in and the ground loop it created was horendous! We actualy had to have no sound 90% of the day and even fucked up a showing to alien ware cos the battery had just died as they came past and we were too embarised to show it with the sound like it was.

    External soundcards go someway to fixing it aparently (alltho i have a feeling this just gets rid of some extra noise caused by components inside the laptop /pc getting picked up by the soundcard due to electromagnetic waves rather then from the power suply ground loop), idealy tho you want all your sound equiipment (anything that carries an analoug signal thru it) like speakers etc on a seperat isolated circit to stuff like pc’s/lap tops.

    i tried several different external soundcards, and it is getting sent from the PC into both the live audio and the ground via the PSU as I tried removing the ground loop. I think the PSU is sending this crap everywhere due to the mains filter picking up radiated RF and feeding it back into the ground,

    out of curiosity, Just had a quick look on the scope (was really fiddly as the probes are them new politically correct sort what are supposed to stop you getting electrocuted) and the output of the laptop PSU is fucking filthy, there’s regular spikes of several milivolts superimposed on the DC on a waveform which is full of harmonics (the scope couldn’t even trigger properly on it but I could just about see the amount of shite coming out of this PSU..

    Yeah, switch-mode PSUs throw all kinds of crap down the earth. I was about to write a long answer, but remembered this thread on Blueroom from a while back and most of the people on there are a lot more experienced than me.

    This should sort the problem and only costs £5.60. I keep meaning to get one for my toolkit for when presenters bring their own laptops and want to run video/audio off them.

    Another suggestion is to take the battery out of the laptop (so the PSU isn’t working as hard trying to charge it the whole time).

    BOOO!!!!!

    Marcus is gonna ring round for me tomorrow – but this new low emissions thing might mean I have to look to sell dirty gertie as I might not be able to afford to convert her……..(as what we’ve read it might be £1500-2500!!!!!)
    I brought her with the thought I would have her for the next 20 yrs, as obviously we didnt know about it then, and that we live right smack bang in the middle of it – and they were talking about an exemption for motorhomes / under a certain mileage recently and didnt go for it…….
