The Rapco LTI-1 laptop interface has a 3.5mm stereo (L and R) input plug with a 3 foot cable attached. It balances the signal and creates L and R XLR outputs for inputs to a mixing console. Additional features are individual Ground LiftsSwitches for L and R outputs, built in Pad, and a Mono switch. The LTI-1 is the best way to make the laptop-to-sound system interface in presentation environments in churches and other presentation settings.
