Using The Tv In A Home Theater - TCL 55US57 User Manual

Using the TV in a home theater

Your TV has several features that make it an ideal TV for a home theater. But you might not notice them
because they remain in the background until you decide to use them.
Turning off the speakers
When you use your TV with a sound bar or an external amplifier and speakers, you'll probably want to
turn off the internal TV speakers.
To turn off the TV's built-in speakers, in the Home screen menu, navigate to Settings > Audio > TV
speakers and change the setting.
Tip: The TV's internal speakers can be enabled and disabled automatically as needed by system
audio control, as described in "Enabling system audio control" on page 69. The internal speakers
are also turned off when you use the headphone jack.
Changing the audio mode
The TV has two audio modes, accessed by navigating in the Home screen menu to Settings >Audio >
Audio mode:
Stereo – Use this setting for internal speakers, headphones, and external stereo amplifiers
•
connected through HDMI
Auto – Use this setting to automatically detect the best audio setting based on the audio stream
•
in the content you are watching. If you have connected the TV to an external Dolby Digital or
Dolby Digital Plus compatible amplifier, receiver, or sound bar through HDMI
optical, the TV automatically selects the appropriate surround sound capabilities of the device
based on the characteristics of the current program.
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:
®
ARC, SPDIF optical, or headphone jack.
