Unbelievably simple laptop question!

[rob1963]

Hi folks,

Next weekend I have a disco where there will be some kind of projection running from a laptop. It has sound, so I've been asked if they can plug the laptop into my system so people can here it.

I just need to know which outputs laptops have, so I know which type of plug I'll need on the end of the lead I get made up.

I've never owned or used a laptop, so I really don't have a clue!

Thanks in advance.

3.5mm

You need something like this

And don't forget the laptop has its own volume control (in software). If like me your CM200 gain setting is around 1 O'Clock then set the laptop volume to about 80% to get even gain across the channels.

Thanks guys...much appreciated.

If anyone is wondering why I didn't just ask the client, I've been dealing with the mother, and the projection will be played on her son's laptop, so I thought it would be simpler to just ask the question here rather than asking the mum, her then contacting her son to ask him & then getting back to me.

With all due respect, Vectis, I don't!

Although my CM100 has photo sockets, the channel 3 output is actually wired to a quarter inch stereo socket on the panel on the back of my console, so I require a lead with a 3.5mm stereo plug on one end & a quarter inch stereo plug on the other...but thanks for the link anyway!

Thanks for the info.

Yes...I usually have my mixer gains around 12 o'clock to 1 o'clock, so I'll make sure the laptop's volume is set to around 80%.

a few things have occurred to me.

1. You'd better hope the Laptop has a decent sound card. If it sounds bad who's going to look the prat in most people's eyes, the chap who's laptop it is or the chap that has the "professional sound system"?

2. You may need a GLI.

3. If you do then you will need completely different leads to the one that you mentioned, as I've only ever seen GLIs with twin phono input / output (although I await correction on whether GLIs are available with jack sockets)

Another big factor to consider when using a laptop, is some of them suffer terribly with 'Ground hum' (earth loop) and need an in line isolator.

Thats what a GLI is as Steve said

OOps ! didn't realise that's what GLI stood for (Ground loop isolator) got it now !

Oh well maybe there's a few others that didn't realise what GLI stood for.
