Select the audio format of the HDMI input.
This is useful when you want to raise voices or bass tones. With the Equalizer you adjust the volume of specific frequencies, so that you emphasize the high or low tones, for example. The option is also useful when you have 2 speakers connected, 1 of which sounds softer because it is farther away. You do this, for example, when you connect headphones and want to compensate for any hearing impairment.
Adjust the volume of the right or left stereo channel.
