ADC-2121 is an analog audio to AES/EBU converter. It is used in i-MOD platform. The module converts 2 analog audio inputs to 2 AES outputs and 2 AES-3id outputs. Output digital audio signals can be synchronized to reference clock signals or digital audio signals. Input level can be displayed via card-edge LEDs.

The ADC-2121 can be controlled locally by means of an intuitive card-edge interface or remotely using i-MOD platform control software IM-MASTER.
