IK Multimedia used the run-up to the NAMM show to unveil a pair of accessories targeted just at iOS users wanting to make professional music. The iRig PRE takes an XLR microphone input and pre-amps it with a typical 3.5mm headphone jack to give live monitoring. The add-on has its own 9V battery and can produce as much as +48V of phantom power for condenser mics, running as long as 15 hours (40 hours on dynamic microphones) without needing a wall plug or sapping the iOS device's battery.
