To use this AVID Venue SC48 digital audio mixing console, first connect it to the power supply included in the package. Make sure the power is switched on. You can use the Ethernet Snake card to connect to other devices as needed. Since there are no analog XLR input and output cards, you'll need to rely on other available connections. When not in use, turn off the console to save energy. Keep it in a dry and clean place to prevent dust and moisture damage. Regularly check the connections to ensure they are secure. If you encounter any issues, refer to the user manual or contact customer support.
