GE Security GEC-B746AVTRST2L MM - Video and 2 Way Audio Digitally Processed Transmitter Rack Card 2 Fibers High Orderd Wavelenght


Our Price : $599.63

Product Code: GEC-B746AVTRST2L


The B746AV series high performance broadcast-grade fiber transmission system supports one-way composite video and two-way High Quality Audio (HQA). The all-digital processing platform features 24-bit audio processing.

Digital Video and Audio Processing:

Digital processing of the video component along with a signal-to-noise ratio >55 dB that assures clean, noise-free video at the receiver. Digital processing of the audio signal along with an audio signal-to-noise ratio >70 dB allows the audio output to drive balanced or unbalanced loads and maintain constant audio levels.

Built-in Diagnostics:

Built-in system performance analysis includes LED displays that provide for complete monitoring of transmitter and receiver operation.
