Cobalt Digital 9321 – HD/SD Embedder

In addition to providing 24-bit basic audio embedding of up to eight analog and 16 AES input channels, the 9321 offers AFD code insertion, full timecode control, and video proc features. Advanced audio features such as AES Sample Rate Converters allow error-free audio embedding from external asynchronous sources.

Timecode can be inserted on the SDI output from selectable sources such as SDI VITC waveform and  SD/HD ATC_VITC/ATC_LTC. +LTC option allows LTC input/output on shared port, with bi-directional conversion between VBI and LTC on RS-485 or any audio I/O.

The 9321 features full user remote and card-edge controls for audio levels and routing, video proc, and other functions. Factory presets enable a return to factory settings.
