I often project video clips for a senior club and put sound from headphone socket through an amplifier but have been getting distortion. Someone suggested a SoundLab Direct Box SDB-40 but couldn't help with wiring fron laptop to amplifier via the Direct Box. Can anyone help please?

Thank for reply and sorry for delay. Not sure what symbols stand for but at the front there is a headphone socket (which I normally use)and I think the one beside it is for the old fashioned mouse connection. At the side there are USB connections, power adaptor socket and connection to projector. There also is what I think is an ethernet connection.

Thanks for reply and sorry for delay. The front connections are a headphone socket (which I normally use) and what looks like the symbol for an old mouse connection (round socket).
At the side are USB connections, a video projector connection, a power adaptor socket and what I think is an ethernet connection.

this may be a silly question but have you tried turning the sound level down on the laptop to about the midway point and use the volume on the external amp, another problem may be if you have any graphic equalizer settings on, are you using windows media player? if so try switching off any audio enhancements off.

Thanks, Koochy. I HAVE tried adjusting sound levels as you suggested, also had graphic equaliser settings at midline. Often I've been using WMV files and projecting through either Windows Media player or Windows Movie Maker.
I'll try your suggestions again. Thank you.

What operating system are you using?

I'm using Vista Home Premium

have you tried clicking on the speaker icon in the task bar? click this then click on mixer and check the sound levels in there (Make sure you have the program you are using to view the videos open)

Thanks again. I don't have the amplifier at home but have always checked the Sound settings on the laptop. I'll have to bring amplifier home to link up and try these suggestions again. Thank you.
