Sound Devices 702T Two-Track Portable Audio Recorder

The 702T: Portable, Two-Track Audio Recorder with Timecode
The 702T two-track digital audio recorder is designed for portable production applications. This compact device is known for its pleasant-sounding, low-noise microphone preamplifiers, the accuracy of its onboard Ambient time code generator, and the ability to record to convenient, removable Compact Flash cards and external FireWire drives.

Recording Reliability with Timecode Accuracy
The two-track 702T on-board timecode reader and generator allow for great flexibility in timecode-based workflows. With the diverse timecode setups encountered in production, the 702T can accommodate all of them: rec run, free run, with/without smart slate, or multiple camera with lockits.
Files captured on this recorder are available for immediate import to broadcast WAV-aware editing applications, such as Avid and Final Cut Pro.
