GE Security GEC-B742AVTRSTL MM - Video and 2 Channel Audio Digitally Processed Rack


Our Price : $1,325.38

Product Code: GEC-B742AVTRSTL


The B742AV series high performance broadcast-grade 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 two audio channels 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 for 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.
