DL240ANA SOLID STATE DELAY LINE (Delay Line Composite Version)

DL240ANA SOLID STATE DELAY LINE (Delay Line Composite Version)

The DL240ANA solid state delay line provides up to120 seconds delay for audio and video signal to give an operator complete control over the program content being broadcast to air.The signal monitoring and alarm features provide input signal error detection.Video input, freeze frame, black field, audio too high and too low errors are all monitored by the DL240ANA.The DL240ANA offers analog composite video input and output, 4 channels balanced analog audio input and output.

The outputs of DL240ANA are all protected by relay bypass.
