Manufacturer's Description:
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, and easily
obtainable. 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.
Features:
- Two-channels of Sound Devices next generation microphone preamps with
phantom, limiters, and high-pass filters

- Aluminum & stainless-steel chassis for exceptional durability and light
weight
- Class-defining compact size
- Designed for the same operational environmental extremes as Sound Devices
field mixers
