AUDIO ANALOG TO BALANCED/UNBALANCED AES CONVERTER WITH AUDIO SYNCHRONIZER

AUDIO ANALOG TO BALANCED/UNBALANCED AES CONVERTER WITH AUDIO SYNCHRONIZER

The ADC6820NS/ADC6820NS4 are an audio A to D converter with audio delay and synchronizer. The two modules can provide two/four balanced audio inputs, two unbalanced and two unbalanced AES outputs. Either DARS or Genlock can be selected as synchronized signal. In addition to manual delay, both ADC6820NS and ADC6820NS4 can receive synchronized signal from video board where the tracking delay is set.
