SG-8 Video Generator (discontinued)

Loss of Signal (LOS) Audio/Video (A/V) ID Inserter

This model has been discontinued. Call us if you need this capability.

The SG-8 is an option to the SG-3 Color Bar/Black Burst Generator. It includes the addition of a Loss of Signal detector/switch and 1 kHz tone generator. Plus three Black Burst outputs.

Program video and audio (balanced or unbalanced) is routed through the SG-8. With program video present at the input to the SG-8, the video and audio outputs of the SG-8 are the program signals. Upon loss of the video portion of the program input, the SG-8 defaults to internal SMPTE Color Bars and 1 kHz tone.

The tone generator has the option of either constant on or 5 seconds on, 5 seconds off. Factory default is constant on.

There are also three Black Burst outputs. These are present at all times and are genlocked to the internal Color Bar Generator.

An ID (example "WABC #2") can be programmed into the SMPTE Color Bar pattern. Consult the factory for details.

Options: ID, Rack mount
