AM/FM antenna connections

Connect the antennas to listen to AM/FM broadcast. When 

listening to the broadcast for the first time, adjust the 

antenna position and orientation to get the best reception.

Taiwanese models)

(European, Australian 

and Asian models)

Assemble the AM loop antenna (supplied).

Network connection

You can enjoy Internet radio, DLNA and AirPlay by 

connecting the unit to LAN. The unit can be connected to 

the router with an Ethernet cable or to the wireless LAN 

router with Wi-Fi connection. In case of wired connection, 

connect the Ethernet cable to the Ethernet port. See "4 

Network Connection" of "Step 2:  Initial Setup" for Wi-Fi 

settings.  

Internet radio

Router

NAS

Headphones connection

Connect stereo headphones with a standard plug (1/4 

inch or ø 6.3 mm) to the PHONES jack on the front panel. 

Sound from the speakers will be off while you are using the 

headphones.

 

If you selected any other listening mode than Pure 

Audio (European, Australian and Asian models), Stereo, 

Mono and Direct, connecting headphones will switch the 

listening mode to Stereo.

Power cord

Taiwanese models include removable power cords. 

Connect the power cord to AC INLET of the unit and then 

connect to the outlet. Always disconnect the outlet side 

first when disconnecting the power cord. When the unit is 

turned on, a large instantaneous current may flow affecting 

functionality of the computer and other devices, so it is 

recommended to use a separate outlet.
