Setting up a digital audio connection
You can connect your Sharp Roku TV to an external amplifier, receiver, or sound bar by using either of these two
connections:
•
HDMI ARC
—The HDMI Audio Return Channel enables your Sharp Roku TV to output digital audio on one of its
HDMI connectors. The connected amplifier can also function simultaneously as an input source to your Sharp Roku
TV, if needed. To use the ARC capability, you must connect an HDMI cable from your amplifier's HDMI ARC
connector to the HDMI ARC connector on your Sharp Roku TV. You also must:
• Be sure your HDMI cable is certified by HDMI.
• Select the appropriate setting under
Settings > Audio >Audio mode
, as explained in
on
page
.
• Enable
HDMI ARC
under
Settings > System > CEC
, as explained in
on page
•
SPDIF optical
—Your Sharp Roku TV has an SPDIF 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 your
Sharp Roku TV. You also must:
• Select the appropriate setting under
Settings > Audio >Audio mode
, as explained in
on page
.
After making the required HDMI ARC or SPDIF optical connection, go to
Settings > Audio > S/PDIF and ARC
option and
select the audio format to use.
Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your Sharp 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 your Sharp Roku TV to the Blu-ray player's input. Or, powering off your Sharp Roku 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 your Sharp Roku 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.
3
On your Sharp Roku TV’s
Home
screen menu, navigate to
Settings > Control other devices (CEC) > Search for CEC
devices
, and then press
OK
to start the discovery process.
When finished, your Sharp Roku TV displays a list of CEC devices that are connected to each HDMI input, as well as any
devices that had previously been connected. Your Sharp Roku TV remembers the names of multiple CEC devices even when
they are no longer connected. If the list is longer than the allowed space, press to see a complete list in a scrollable
window.
Enabling HDMI ARC
HDMI ARC is the audio return channel that is available on one of your Sharp Roku TV’s HDMI ports. The audio return channel
enables you to send a Dolby Digital audio signal back to a home theater receiver that is also sending an audio and video
signal into your Sharp Roku TV. Using HDMI ARC reduces the number of cables needed and optionally lets you control the
volume and mute state of the receiver by enabling system audio control.
HDMI ARC is disabled by default. To enable HDMI ARC, in the
Home
screen menu, navigate to
Settings > Control other
devices (CEC)
, and then highlight
HDMI ARC
. Press
OK
to check the adjacent check box.
Note
Dolby Digital Plus format is only output through the HDMI ARC connection.
Note
In most cases, Auto detect is the best option. Other settings can result in no sound
when the content you are viewing does not contain the audio stream type you
selected.
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.
