ADC24 - 4 channel 24 bit audio A/D converter with AES/EBU bypass inputs

Description

The ADC24 is a multi-functional product. Its basic function is the conversion of analog audio to AES/EBU digital audio. In addition to the analog inputs it has AES/EBU inputs with a sample rate converter (SRC). The ADC24 has a tracking audio delay, and a delay offset of up to 650ms at 96kHz or 1300ms at 48kHz. It can also perform the Synapse ADD-ON function. In ADD-ON mode the card acts as an analog or digital audio input board that feeds a master card positioned one slot left of the ADD-ON card. The ADC24 for example acts as a analog audio embedder if used in combination with the ASV12, SFS11 or HFS11 (many more options available). The audio data that enters the Synapse bus to a master card is identical to the data present in the local AES/EBU outputs. The AES/EBU in- and outputs are available on 75 Ohms BNC or 110 Ohms on screw terminals and sub-D connectors. This selection is determined by the type of connector panel.
