Sound Devices 702 2-channel Portable Digital Audio Recorder

DISCONTINUED
Sound Devices 702 2-channel 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 and/or external FireWire drives, 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.
