Description
722 Portable, High-Resolution Audio Recorder
The two-channel 722 from Sound Devices 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 records and plays uncompressed PCM audio at 16 or 24 bits
with sample rates between 32 kHz and 192 kHz. Compressed (MP3) audio recording and lossless FLAC recording 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.
Its two internal drives (hard drive and Compact Flash) are highly reliable, industry standard, and easily obtainable. 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
