Setup Guide
1. Placement
Position the sound bar centrally below your TV. Ensure the wireless subwoofer is placed within 10 meters (33 feet) of the sound bar for optimal wireless connection and bass performance. Avoid placing the subwoofer directly against a wall or in a corner, as this can cause excessive bass resonance.


2. Connections
Connect the sound bar to your TV and other devices using the appropriate cables. The SK10Y offers multiple connectivity options:
- HDMI ARC (Recommended): Connect an HDMI cable from the TV's HDMI ARC port to the sound bar's HDMI OUT (TV ARC) port. This allows audio from the TV to be sent to the sound bar and enables TV remote control of the sound bar.
- Optical: Connect an optical cable from the TV's optical digital audio output to the sound bar's OPTICAL IN port.
- HDMI IN (2 ports): Connect external devices (e.g., Blu-ray player, game console) to the sound bar's HDMI IN ports. The sound bar supports 4K pass-through (HDCP 2.2).
- Portable In (3.5mm): For connecting portable audio devices.
- LAN: For wired network connection.
- USB (Service Only): For firmware updates.

3. Power Connection
Connect the power cable to the sound bar and then to a wall outlet. Do the same for the wireless subwoofer. The subwoofer will automatically pair with the sound bar once both are powered on. A green LED on the subwoofer indicates a successful connection.
4. Initial Setup and App Installation
For advanced features and easier control, download the "LG Wi-Fi Speaker" app (available on iOS and Android) to your smartphone or tablet. This app allows for network setup, firmware updates, and sound mode adjustments.
