The digital output on the rear panel of the Aurender needs to be connected to the corresponding digital input of a DA converter or amplifier. Before connecting any digital cables, first check to see that all devices are grounded. This should be done by connecting the power cords using grounded plugs and grounded sockets. In addition, all devices should be turned off, before connecting any digital cables. If the devices are not grounded, a voltage potential difference between devices can cause a voltage surge through the digital cable that can weaken and eventually damage sensitive circuits in D/A converters and other devices.
The Ethernet port should be connected to a wireless router, before turning on the Aurender. The wireless router is needed to use the iPad and connect to the Internet for updates. It is recommended that the Aurender be connected to the router using a wired connection for faster file transfers.
