The 788T: Portable, Eight Input, Twelve-Track Recorder with Time Code

The 788T and 788T-SSD from Sound Devices are powerful eight input, twelve-track digital audio recorders designed for production sound. Building on the success of the proven 7-Series architecture, the 788T offers greatly expanded input and output connectivity while continuing the 7-Series heritage of extensive control in a compact package.

Its eight full-featured inputs ensure superb audio quality. They accept either microphone or line-level signals, provide 48 V phantom power for condenser microphones, offer peak limiters for microphone inputs, and fully adjustable high-pass filters. Support for AES42 digital microphones is also available. Extensive routing flexibility allows each input to be routed to left/right mixed tracks, isolated tracks, or aux tracks. With optional CL-8 or CL-9 Controllers, the 788T is even easier to use, making the combination a flexible mixer/recorder, with extensive operational flexibility.

 

The 788T has three options for recording media, internal 160 GB SATA hard drive (256 GB SSD in the 788T-SSD), CompactFlash media with UDMA support, or an external FireWire hard drive or DVD-RAM (with bus powering). Any or all of these can be used simultaneously. Additionally, when connected to Mac OS, or Windows computers with high-speed USB or FireWire 400/800, the 788T functions as a high-speed mass storage device.

To

simplify interconnection with mixers and cameras with AES3 connectivity, the 788T has eight channels of balanced AES3 digital input and six channels of balanced AES3 output. The 788T can be clocked from external word clock or from video sync. The 788T has a high-accuracy time code reader/generator on board. It includes auto-record features to chase external rec-run video sources. To simplify metadata entry the 788T directly accepts USB keyboards. Keyboard shortcuts can be programmed to control menu items and machine transport. The extensive power of the 788T simplifies any production sound setup
