The 744T is a powerful four-track file-based digital audio recorder. The super-compact 744T records and plays back audio to and from its internal hard drive or Compact Flash medium, 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 192 kHz. Compressed (MP3) audio playback and recording from 64 kb/s to 320 kb/s are also supported. The time code implementation makes the 744T ready for any recording job—from over-the-shoulder to cart-based production. The 744T 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 744T 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 two recording media (hard drive and Compact Flash) are highly reliable, industry standard, and easily obtainable. The removable, rechargeable battery is a standard Sony-compatible Li-ion camcorder cell. The 744T interconnects with Windows and Mac OS computers for convenient data transfer and backup.
