Notes
If the TV does not support ARC, connect the processor and the TV with an optical digital
cable. (Connection example 2 [Details], Connection example 4 [Details])
Use the headphones within the signal transmission range. [Details]
When you listen to the sound of movies, if you turn up the volume too much at quiet
scenes, the sound of the noisy scenes, such as explosions, will be so loud that it may
damage your ears. Pay attention to the volume level.
