"iRig Pre HD is a high-quality microphone preamp and digital interface, letting you connect any microphone to an iPhone, iPad, Android device or Mac/PC with superior sound quality and professional features. First, iRig Pre HD offers a studio-quality class A- microphone preamp with phantom power for use with condenser and ribbon mics. An adjustable input gain lets you dial in the ideal level for any use, and a multicolor LED indicates signal quality so you can see at a glance if things are too loud. Second, iRig Pre HD offers a 24-bit, 96 kHz audio interface to preserve your signal. The headphone output switches between pre- and post- device, so you can monitor the sound directly when using video and streaming apps, or listen back to the recorded sound after it's been processed by any apps. iRig Pre HD includes Lightning and USB cables to connect to any iPhone, iPad or Mac/PC, and will also work with Android devices with the optional cable. It's powered by 2 AA batteries (included) when used with smartphones or tablets, so it won't run your device's battery down. And iRig Pre HD includes a suite of powerful recording apps and software, including IK's award-winning Mic Room microphone modeling software so you can record with the sound of an entire studio's worth of mics no matter which one you own. All together, iRig Pre HD offers a complete mobile recording solution perfect for podcasting, live streaming, music recording and more, all in an ultra-compact package you can take anywhere."
