Overview
The B746AV and B7746AV series high performance 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 signalto-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.
