3. Detailed explanation of HDMI ARC connection (currently the most popular solution)
1.Device confirmation: Check whether the HDMI interface of the TV and amplifier is marked with "ARC", usually located at the HDMI 1 or HDMI 2 interface.
2.Connection steps:
• Use a high-quality HDMI cable to connect the TV ARC interface and the amplifier ARC interface
• Go to TV Settings→Sound→Audio Output and select "HDMI ARC"
• Switch the power amplifier input source to the corresponding HDMI channel
3.Frequently Asked Questions:
•No sound output: Check whether the CEC function is turned on (different brands are called Anynet+/Bravia Sync, etc.)
•Volume out of sync: Enable HDMI control function in amplifier settings
4. Optical fiber audio connection solution
1.Advantage analysis: Completely eliminates electromagnetic interference, supports 5.1 channel transmission, and is suitable for users who pursue pure sound quality.
2.Operation process:
• Plug the optical cable into the TV’s OPTICAL OUT connector
• Connect the other end to the OPTICAL IN interface of the power amplifier
• TV audio output changed to "Optical/Digital Audio"
• The amplifier selects the corresponding digital input source
5. Answers to users’ high-frequency questions
Q: After connecting, there is only background music and no sound?
A: This is a typical center channel loss problem. You need to check whether the audio format is set to "Bitstream" or "Original" to avoid TV decoding and compression.
Q: How do I connect an old amplifier to a new TV?
A: You can use an HDMI audio splitter, or convert the RCA analog signal input to the power amplifier through the headphone jack of the TV.
6. Equipment purchase suggestions
| Device type | Recommended features | Popular models |
|---|---|---|
| amplifier | Support eARC/Dolby Atmos | Denon AVR-X series |
| HDMI cable | 18Gbps bandwidth/gold-plated connector | Zeskit Maya Series |
Through the above structured solution, you can choose the most suitable connection method according to the equipment situation. It is recommended to give priority to the HDMI ARC solution, which is currently the most convenient and fully functional technical standard. If you encounter operational problems, you can consult the device manual or contact the manufacturer's technical support.
