Connecting an AV receiver or digital sound bar

You can enjoy Dolby Audio™ multichannel sound from your TV if you connect a digital

amplifier or sound bar (not provided) in either of two ways:

• Digital optical audio out (S/PDIF) – Connect a TOSLINK optical cable (not

provided) from the TV to the Optical input on your receiver or sound bar.

• HDMI

ARC – Connect an HDMI

cable (not provided) from the HDMI (ARC)

connector to the HDMI

input on your receiver or sound bar. This connection

uses the Audio Return Channel (ARC) feature of the HDMI

specification to

output sound from the TV to a compatible device. To use this feature, you

must configure the TV to enable HDMI

ARC, as explained in Enable HDMI

ARC.

Preparing for Internet connectivity

If you want to watch streaming content and take advantage of the cool features of

your TCL Roku TV, connect it to the Internet through a wireless modem/router or a

wireless access point (not provided). The TV has a built-in wireless LAN adapter.

Note:

The TV supports only its internal wireless network adapter—it does not support

the use of a USB network adapter.
