DL240-SDI2 SOLID STATE DELAY LINE

DL240-SDI2 SOLID STATE DELAY LINE

The DL240SDI solid state delay line provides up to 120 seconds delay for audio and video signal to give the operator complete control over the program content being broadcast to air. DL240SDI2 offers main and standby SDI video signal inputs, each input supports 2 channels balanced analog audio inputs, and 2 channels embedded audio inputs. Main SDI video signal input is used as delay adjustment, and works under normal circumstance; Standby SDI video signal input provide the output signal with more reliable signal guarantee. DL240SDI2 has ample interfaces for monitoring, provide all-round analog audio monitoring interface before or after delay.

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 2.

The outputs of DL240SDI are all protected by relay bypass.
