702 Portable, High-Resolution 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.

702T High-Resolution Digital Recorder with Time Code
The two-channel 702T is a powerful two-track file-based digital audio recorder with time code. The super-compact device records and plays back to convenient,
removable Compact Flash cards, making field recording simple and fast. It writes and reads uncompressed PCM audio at 16 or 24 bits with sample rates between 32 kHz and 19 2 kHz. Compressed (MP3) audio playback is also supported.
The 702T shares all the features of the 702 but with the addition of Full-function, ultra-stable Ambient time code functionality tuneable to <0.2 PPM accuracy
with all relevant TC rates. The time code implementation makes the 702T perfect for any dual-system video or film production application.
