3.3 Connecting to Your TV and Devices
The HT-CT370 offers multiple connectivity options for your TV and other audio/video devices.


- HDMI (ARC) Connection (Recommended):
- Connect an HDMI cable from the HDMI OUT (TV ARC) port on the sound bar to the HDMI input on your TV labeled ARC.
- This connection allows audio from your TV to be sent to the sound bar and enables control of the sound bar with your TV remote (if your TV supports HDMI CEC).
- Optical Digital Connection:
- If your TV does not have an HDMI ARC port, connect the supplied optical cable from the OPTICAL (TV) port on the sound bar to the optical digital output on your TV.
- Ensure the optical cable is securely inserted into both ports.
- Connecting External Devices (HDMI IN):
- Connect up to three external devices (e.g., Blu-ray player, game console, cable box) to the HDMI IN 1, 2, or 3 ports on the sound bar using HDMI cables.
- The video signal will pass through to your TV, and the audio will be played through the sound bar.
- Analog Connection:
- For devices with analog audio output, connect an analog audio cable (not supplied) from the device's audio output to the ANALOG IN port on the sound bar.
3.4 Power Connection
- Connect the AC power cord of the sound bar to a wall outlet.
- Connect the AC power cord of the wireless subwoofer to a separate wall outlet.
- The sound bar and subwoofer will automatically attempt to establish a wireless connection. If the connection is not established, refer to the Troubleshooting section.
