Speaker Select (External / Internal)
If you are listening to the sound track of a broadcast or movie through an external receiver, you may hear a sound echo caused by the difference in decoding speed between the product speakers and the speakers attached to your audio receiver. If this occurs, set the product to External.
When you set Speaker Select to External, the product speakers are turned off. You will hear sound through the external speakers only. Sound will be audible only from the external speakers if external speakers are connected when Speaker Select is set to Internal.
If there is no video signal, both the product speakers and the external speakers will be mute.
Auto Volume (Off / Normal / Night)
Normal equalizes the volume level on each channel, so that when you change channels, the volume level is the same.
Night equalizes and decrease the volume level on each channel, so each channel is quieter. Night is useful at night, when you may want to keep the volume low.
To use the volume control of a connected source device, set Auto Volume to Off. A change to the volume control of the connected source device may not be applied if Auto Volume is set to Normal or Night.
