Sound Devices 744T Digital Four-Track Audio Recorder with Time Code


The 744T is an ultra-portable, four-track file-based digital audio recorder. Known for pleasant sounding microphone preamps, the 744T is credited with frequency response linearity while maintaining very low distortion and noise.

Intuitive Control
No other recorder on the market matches its size, features, and durability. In addition, the 744T is designed to place an abundance of control in the hands of the user, while the menu architecture provides intuitive operation. The onboard time code generator and Sony-compatible Li-ion camcorder battery makes the 744T ready for any recording job—from over-the-shoulder to cart-based production.

Data Storage and Transfer
The 744T records uncompressed PCM or compressed MP3 audio to its internal hard drive, a Compact Flash card, and an external FireWire drive allowing for flexibility to compliment the required workflow. It can be connected to Mac OS or Windows computers with FireWire 400 for high-speed data transfer.

Unmatched Portability
The 744T possesses unmatched capability for its compact package when used as stand-alone portable recorder. It truly excels when preceded by a portable audio mixer such as Sound Devices' 664, 552 or 302.
