Description
 
The B7748AV series high performance, broadcast-grade fiber transmission system supports two-way composite video and two-way 2-channel line-level audio and contact closure. The all-digital processing platform features 24-bit dual channel audio processing.

Digital processing of the video signal along with a video SNR >65 dB assures clean, noise-free video at the receiver. Digital processing of the audio signal along with an audio SNR >90 dB allows the audio outputs to drive balanced or unbalanced loads and maintain constant audio levels.

The links employ an extensive set of built-in diagnostic tools including video and audio test generators and LED displays. The video test pattern generator allows failures to be diagnosed from the monitor while the LEDs monitor video and audio status and optical signal strength.
