Step 3:   Playing Back

It is possible to perform playback in the main room and a 

separate room at the same time, for example by playing 

the Blu-ray Disc player in the main room where the unit is 

placed while playing Internet radio in a separate room. It is 

also possible to perform playback only in a separate room.

 

● With external players, it is possible to play the same 

source or different sources in the main room and 

separate room.

 

● With "NET" and "BLUETOOTH", you cannot select 

different inputs for the main room and separate room. 

For example, if "NET" has been selected in the main 

room and then "BLUETOOTH" is selected as playback 

source in the separate room, the input in the main room 

will change to "BLUETOOTH" accordingly.

 

● When listening to AM/FM broadcasting, you cannot 

select different stations for the main room and separate 

room. Therefore broadcasting of the same station will be 

heard in the both rooms.

zRECEIVER�

"Z2" lights on the main unit display and the multi-zone 

function is enabled. (Zone 2 is now on.)

 

● If you turn the unit to standby during multi-zone 

playback, the Z2 indicator is dimmed and the 

playback mode is switched to playback in a separate 

room only. Performing steps 1 and 2 while the unit 

is in standby also switches the playback mode to 

playback in a separate room only. To play the same 

source in the main room and separate room, hold 

down ZONE2 for approximately 3 seconds.

To control on the main unit: press ZONE2 and within 8 

seconds, press the input selector button of the source to be 

played in the other room. (To play the same source in the 

main room and separate room, press ZONE2 twice.)

After pressing ZONE2 on the remote controller, press 

zRECEIVER. Alternatively press OFF on the main unit.

 

● If ZONE 2 is on, power consumption during standby 

becomes larger than normal.

 

● If ZONE 2 is turned on when the listening mode of the 

main room is Pure Audio, it will automatically switch to 

the Direct listening mode. (European, Australian and 

Asian models)

 

● While ZONE 2 is on, the RI linked system function 

(interlink between Onkyo components) is disabled.

 

● Pressing INPUT SELECTOR on the remote controller 

while you are using the remote controller for Zone 2 will 

switch the controlled target to the main room. To control 

Zone 2 again, press the ZONE2 button to enter the 

Zone control mode.
