10, 11. USB 2.0 Data Ports

Both ports can be used to copy files from USB memory devices. Either port can also be connected to dCS systems by using the optional USB to RS232 dongle. Connecting the dCS RS232 control cable will enable automatic clock selection between the Aurender W20 and the dCS Master Clock. These ports should not be used as audio outputs.

12. Gigabit Ethernet Port

To connect to a network and Network Attached Storage (NAS) devices. The Aurender is able to stream music from NAS. The ethernet cable to the network router should be connected before turning on the Aurender.



Before connecting audio cables, first check to see that all devices are grounded using grounded plugs and grounded sockets. In addition, all devices should be turned off, before connecting any audio or digital cables. If the devices are not grounded, a voltage potential difference between devices can cause a voltage surge through the audio cable that can weaken and eventually damage sensitive circuits in D/A converters and other devices.


System Installation

To set up the Aurender W20 Reference Music Player and iPad application, please follow the instructions below:
Connect the Aurender to the following:
A power outlet using the AC power cord that came in the box. Check that the voltage marked on the rear panel matches the local voltage.
