Sound Devices 722 Portable, High-Resolution Audio Recorder

SD-722 High-Resolution Audio Recorder     
The 722 two-track file-based digital audio recorder is designed for applications where high-resolution audio capture is essential in a portable, durable device. This compact recorder is known for pleasant-sounding low-noise microphone preamplifiers, and the flexibility to record to its internal hard drive and removable Compact Flash cards.

The ultimate DAT upgrade. The two-track 722 breaks limitations of 16-bit DAT and opens the world of high-resolution 24 bit, 192 kHz (sampling) audio recording. Storage is to internal 40 GB hard drive or removable Compact Flash (or both). The sub-three pound 722 is powered from standard Li-on camcorder batteries or external 10–18 VDC.
