For anyone attempting to interface a computer, tablet or smartphone with a professional sound system, here’s my favorite solution. Its called the Switchcraft 318 and it lets you hook up any 1/8″ stereo headphone jack up to a standard XLR microphone input. The 318 has an integrated ground lift switch to help eliminate stray hums or buzzing, a small volume control on the top and doesn’t need batteries. Best of all, it’s make of a solid block of aluminum , so you won’t break it unless you run over it with a truck. No more long chains of adapters, usb powered external stuff or dead batteries. The 318 even includes the 1/8″ cable to connect your device. The 318 is a simple solution and smaller than your phone.
But whatever you do, don’t do this:
While it looks like a cheap solution, it’s actually made to connect an XLR mic to a 1/8″ stereo mic input and and the output of your laptop will overdrive the input of the sound board, creating distorted sound.
