Product Overview

The two-channel 722 is a powerful file-based digital audio recorder. The super-compact device records and plays back audio to internal hard drive, CompactFlash cards, or external FireWire drives. It writes and reads uncompressed PCM audio at 16 or 24 bits with sample rates between 32 kHz and 192 kHz. Compressed (MP3) audio playback from 64 kb/s to 320 kb/s are also supported.

The 722 implements a no-compromise audio path that includes Sound Devices’ next generation microphone preamplifiers. Designed specifically for high bandwidth, high bit rate digital recording, these preamps set a new standard for frequency response linearity, low distortion performance, and low noise.

No other recorder on the market matches its size or feature set. In addition, its learning curve is quite short—powerful does not mean complicated. While the 722 is a very capable recorder by itself, it truly excels when used in conjunction with an outboard audio mixer such as Sound Devices’ own 442 or 302.

The 722 includes a 160 GB SATA Drive and the SATA interface. The removable, rechargeable battery is a standard Sony-compatible Li-ion camcorder cell. The 722 interconnects with Windows and Mac OS computers for convenient data transfer and backup.
