Sound Devices 702
Portable, Digital Audio Recorder
The two-channel 702 is
a powerful file-based digital audio recorder. The compact device records and
plays back audio to cost-effective, removable Compact Flash cards, making field
recording simple and fast. It writes and reads uncompressed PCM audio at 16 or
24 bits with sampling rates between 32 kHz and 192 kHz. Compressed (MP3) audio
playback is also supported.

The 702 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 702 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 Compact Flash storage is a highly-reliable industry
standard. The removable, rechargeable battery is a standard
Sony-compatible Li-ion camcorder cell. The Compact Flash card
appears as a removable storage devices when connected via the
FireWire port to Windows or Mac OS computers.
