delay line/ DL240 |
|
| |
Description :
The DL240SDI solid state delay line provides up to 116 seconds delay for audio and video
signal to give the operator complete control over the program content being broadcast to air.
The signal monitoring and alarming 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 the DL240SDI.
|
|
 |
The DL240SDI offers serial component digital video, 4 channels balanced analog audio
input and output, 2 pairs balanced AES/EBU audio input and output.
The DL240SDI can also support 4 channels embedded audio input and output.
The outputs of DL240SDI are all protected by relay bypass.
