SD-702 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
