I can't say enough good things about this mixer/recorder. Nothing beats it until you get up to the Sound Devices level.
Four track recorder allows you to record high quality audio into 4 separate channels. The ultra-portable unit weighs under three pounds but packs a number of great features.
The analog nature of the mixer makes it easy to operate by feeling around, while still holding a boom or keeping your eye on the action.
You can quickly switch between monitoring individual channels to monitoring two or four channels in stereo, which is super helpful when trying to isolate an audio issue on the fly.
Individual phantom power available to each channel.

Record up to four channels of linear PCM audio at a variety of bit rates and sampling frequencies; up to 24-bit/192kHz!
