To use the ARC function, connect to the ARC 

compatible HDMI jack of the TV and make an 

appropriate setting on the unit. See "2 Source 

Connection" of "Step 2:  Initial Setup".  

HDMI cable connection

The unit has many HDMI jacks on its rear panel and each 

of them corresponds to an input selector button of the 

same name on the front panel. For example, a Blu-ray Disc 

player will be connected to the HDMI IN1 jack and the BD/

DVD button on the front panel will be used to listen to the 

playback sound (if the player is CEC compliant, input will 

be switched automatically when play is started). If you add 

another Blu-ray Disc player, you can use any other jack 

than HDMI IN1. It is possible to change assignment of the 

input jacks and input selector buttons. For how to make 

settings, see the Advanced Manual.
To connect the TV and the unit, connect the HDMI OUT 

MAIN jack of the unit and the HDMI IN jack of the TV using 

a HDMI cable. With this connection, it becomes possible to 

display the setting screen of the unit on the TV or transmit 

video/audio signals from the player to the TV. If your TV 

supports ARC (Audio Return Channel), it is possible to 

play the TV sound with the AV receiver's speakers with 

this connection only. If your TV does not support ARC, you 

need, in addition to the HDMI OUT MAIN jack connection, 

a digital optical cable connection between the digital audio 

out optical jack of the TV and the DIGITAL IN OPTICAL 

jack of the unit or an analog audio cable connection 

between the audio output jack of the TV and the AUDIO IN 

TV jack of the unit.
