IK Multimedia's iRig Mix mixer has finally arrived in stores, and it's just as impressive now as it was back when we saw it in action at CES this year. The mixer is sturdy and impressively small, and it has hookups for two different sources, including two iOS devices or any other stereo input source, as well as an extra mic/instrument input. Those sounds can then be mixed together, balanced, or tweaked with EQ, and sent out to a headphone jack on the bottom, and a stereo RCA output on the top. In short, this is a great full-featured mixer for mixing together sounds from almost anywhere.
The biggest bonus here, however, is that the mixer also works with IK's apps on the App Store, so downloading DJ Rig or any of the other apps will sound extra nice coming through this thing. And there's an X-Sync feature built in to the mixer that works with the DJ app to beatmix for you, making for super simple DJing: Just start up the apps on your iOS devices, turn X-Sync on, and the mixer will beatmatch automatically.
The whole kit is very impressive, and even if you just need a mixer for occasional audio use (unrelated to your iOS devices), it would probably work great. Plus, it's out now for just $99, and good luck finding an equivalent professional mixer at that price.
