The SmartRig+ Di from Saramonic is a two-channel audio interface that allows you to connect professional microphones or guitars to your iPhone, iPad, and iPod touch device. With a lightning connector output, the interface can be used to record stereo sound or music to your iOS portable device. The SmartRig+ Di provides 48V phantom power for condenser microphones and is equipped with two XLR inputs, two 1/8" inputs, and two 1/4" inputs, and an 1/8" headphone output for real-time monitoring. There are two gain-control thumbwheels that make it easy to set levels for each channel separately.
