Auto: The receiver outputs HDMI signals to the TV from the HDMI OUT jack when the
TV is turned on while the receiver is in the standby mode.
Sony recommends this setting if you are using a "BRAVIA" Sync-compatible TV
manufactured by Sony. This setting saves power in the standby mode compared to the
[On] setting.
On: The receiver continuously outputs HDMI signals from the HDMI OUT jack when in
standby mode. Sony recommends this setting if you are using a TV that is not
manufactured by Sony.
Off: The receiver does not output HDMI signals when in standby mode. This setting
saves power in the standby mode compared to the [On] setting.
Note
When the receiver is in standby mode, the power indicator on the front panel lights up in amber if
[Standby Through] is set to [On] or [Auto].
When [Auto] is selected, it may take a little more time for the image and sound to be output to the TV
than when [On] is selected.
This function does not work for the HDMI OUT B/HDMI ZONE jack.
[Auto] may work on other devices than those manufactured by Sony. However, operation is not
guaranteed.
