Channel: LG USA
TL;DR
This guide explains how to connect an LG Smart TV to a home theater system using either ARC HDMI or optical audio cables. It details the physical connection steps for both methods and provides instructions on adjusting the TV's sound settings to route audio externally.
Key Points
- — Smart TVs now act as the hub for home entertainment, requiring audio to be sent from the TV to external sound systems.
- — If both devices support ARC, connect a high-speed HDMI cable from the TV's first HDMI port to the sound unit's ARC port.
- — For devices without ARC support, use an optical audio cable, connecting it to the TV's optical digital audio out and the sound device's input.
- — Navigate to the TV's sound settings to change the output to 'External Speaker' to disable internal speakers.
- — Ensure the receiver is set to the correct input and remember that volume is now controlled by the external device's remote.
Detailed Summary
Modern Smart TVs serve as the central hub for home entertainment, often requiring audio from streaming services to be routed out to a home theater system for better sound quality. The video outlines two primary connection methods. The first is using Audio Return Channel (ARC) via a high-speed HDMI cable, which connects the TV's first HDMI port to the ARC port on the sound unit. If the components do not support ARC, the alternative is using an optical audio cable. This involves connecting the cable to the TV's optical digital audio out port, which may be behind a protective cover, and the corresponding input on the sound device. Users are advised to avoid bending the optical cable to ensure the light pulses transmit correctly. After physically connecting the cables, the TV's internal settings must be updated. Users need to navigate to the Sound menu, select 'Sound Out,' and choose 'External Speaker.' This action disables the TV's internal speakers to prevent audio conflicts. Finally, it is crucial to ensure the home theater receiver is switched to the correct audio input to receive the signal. Once set up, volume control shifts from the TV remote to the external device's remote or physical knobs, completing the audio configuration.
