For example, when users play high-definition video directly on the projector, they need to connect to the amplifier if they want to enjoy 5.1-channel audio.
According to the traditional method, it is necessary to connect the power amplifier to decode through the light/coaxial digital audio output port on the projector.
But if you have the
HDMI ARC interface, you don't have to be so troublesome, you can directly decode the 5.1 channel of digital audio through the
HDMI cable.
