DL240-SDA SOLID STATE (Delay Line SD Composite Version)

DL240-SDA SOLID STATE (Delay Line SD Composite Version)

The DL240SDA solid state delay line provides up to 120 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, audio input, EDH, freeze frame, black field, audio too high and too low errors are all monitored by DL240SDA.

The DL240SDA offers serial component digital video, analog composite video input and output, 4 channels balance analog audio input and output, 2 pairs balanced AES/EBU audio input and output.

The DL240SDA can also support 4 channels embedded audio input and output. The outputs of DL240SDA are all protected by relay bypass.
