Overview
The B742AV and B7742AV series high performance broadcastgrade fiber transmission system supports one composite video
channel and two channels of line-level audio. The all-digital
processing platform features 24-bit audio processing.
Selectable Audio Levels
For added flexibility, dual range audio levels for the audio channel
can be configured for -10 dB to +8 dB or 0 dB to +18 dB operation.
Built-in Diagnostics
Two multi-segment LED displays provide complete monitoring
of input video, output video, audio input and audio output
levels and the received optical signal. When switched to the
test mode on the receiver, the front panel LEDs have the
capability to display the received optical level. This built-in test
feature aids in the installation process as it easily measures
the actual optical loss in the fiber run from the transmitter.
