Non-ARC TV
This unit is connected between your TV and AV
components. If you connect two or more AV components,
you can select the video displayed on the TV and the
audio output from this unit by changing the input selector.
This describes the connections for a TV that does not
support the ARC (Audio Return Channel) feature. By
connecting with both an HDMI cable and a digital optical
cable, you can not only output the video input to this unit
to the TV, but you can also play the sound from the TV
through this unit.
If the TV doesn't have a DIGITAL OPTICAL OUT jack, use
an analog audio cable and connect the TV's ANALOG
AUDIO OUT jack to the AUDIO IN TV jack on this unit.
0 Connection with a digital optical cable is not necessary
if you will watch TV through a device such as a cable
set-top box (that is, not use a tuner built into the TV)
that you have connected to the INPUT jack on this unit.
