To use this Studer AES/EBU card, first make sure your D21m Modular I/O System is powered off. Carefully insert the card into the appropriate slot in the system. Once it's securely in place, power on the system. You can then connect your audio sources to the 16 - channel input and connect your audio destinations to the 16 - channel output. When using it, avoid exposing it to extreme temperatures or humidity. Also, keep it away from strong magnetic fields. For maintenance, it's a good idea to clean the card's connectors gently with a dry, soft cloth every few months. If you encounter any issues, check the connections first and then refer to the system's user manual.
