Note: Dolby Digital Plus format is only passed through the HDMI ARC connection.
Setting up a digital audio connection
You can connect the TV to an external amplifier, receiver, or sound bar by using either of these two
connections:
• HDMI ARC – The HDMI Audio Return Channel enables the TV to output digital audio
on one of its HDMI connectors. The connected amplifier can also function
simultaneously as an input source to the TV, if needed. To use the ARC capability, you
must connect an HDMI cable from your amplifier’ HDMI ARC connector to the HDMI
ARC connector on the TV. You also must:
o Be sure your HDMI cable is certified by HDMI.
o Select the appropriate setting under Settings > Audio > Digital audio out, as explained
in “Changing the audio mode” on page 58
.
o Enable HDMI ARC under Settings > System > CEC, as explained in “Enabling HDMI ARC”
on page 60.
• DIGITAL AUDIO OUT – The TV has a DIGITAL AUDIO OUT optical connector that
outputs a digital audio signal. To use the optical output, connect a TOSLINK optical
cable from the amplifier to the Optical or SPDIF connector on the TV. You also must:
o Select the appropriate setting under Settings > Audio > Digital audio out, as explained
in “Changing the audio mode” on page 58
.
Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your Hisense • Roku TV and other CEC-compatible home
entertainment components to control one other in various ways. First, the CEC-compatible devices must
“discover” one another and report their capabilities. After this, one device can control another
according to the features you enable. For example, playing a disc on a Blu-ray player could switch the TV
to the Blu-ray player’s input. Or, powering off the TV could also power off the Blu-ray player and the
home theater receiver.
Discovering connected CEC devices
To discover CEC devices:
1. Make sure that your CEC-compatible components are connected to the TV with a suitable high-
speed HDMI cable that supports HDMI ARC and CEC control.
2. Turn on each component and make sure all components have CEC enabled.
Tip: Some manufacturers have their own branded names for CEC functionality, so you might
need to read the product documentation to correctly identify the CEC features of the device.
