Using your Klark Teknik Digital Audio Network Bridge is straightforward. First, connect the included power supply to the bridge and then to a power outlet. Make sure the power is stable to avoid any disruptions. When it comes to network connections, since it doesn't have a network module, you'll need to use your own compatible one. Connect it to your audio devices as per the device's connection requirements. As for maintenance, keep the bridge in a clean and dry environment. Avoid exposing it to extreme temperatures or humidity. Regularly check the power supply for any signs of damage. If you encounter any issues, consult the official Klark Teknik support for assistance.
