The Zoom H4 mobile recorder packs a lot of recording punch into its six-inch size, with professional features such as four track recording, two XLR inputs and phantom power.
It has two internal condenser microphones and can record 24-bit/96 kHz uncompressed digital audio, or if you're running out of disk space on your SD memory card, save room by recording direct to MP3 with bit rates up to 320kbps. And hey, in a pinch it even acts as an audio interface for recording directly to your PC. Its most amazing attribute is the price, $299.
