- Yamaha Soundbar (YAS-209)
All these devices are connected using HDMI cables. With HDMI-CEC enabled, here’s what happens when you press the “Play” button on your Blu-ray player:
- The Blu-ray player sends a signal to the TV via HDMI-CEC, instructing it to switch to the correct HDMI input.
- The TV automatically switches to the corresponding HDMI input, and the Blu-ray player’s menu appears on screen.
- As the Blu-ray player begins to play a movie, it sends a signal to the soundbar to turn on and adjust the volume to a predetermined level.
- The soundbar then turns on, and the volume is adjusted accordingly.
This seamless interaction between devices creates a more immersive viewing experience, eliminating the need to manually switch between inputs or adjust volume levels.
