Yes the SL600 will work with an iPad.
If you have the new iPad Pro we recommend purchasing the microphone to USB-C Cable found here...
If you have an iPad with a lighting connector we recommend you grab Apples official dongle which provides extra power (as the SL600 is a powerful microphone.) This will help you to power your iPad whilst you record and also reduce the chances of your SL600 losing power during recording.
You'll also need a recording app on your iPad such as Garageband. (USB microphones do not work with the built in camera/video app of the iPhone or iPad.)
