When connecting a non­CEC compatible component, or when you are not
sure whether it is compatible, set the setting to "Off".
HDMI Standby Through
Default Value: Off
When this is set to anything other than "Off", you can play the video and
audio of an HDMI connected player on the TV even if the unit is in standby
mode. Only "Auto" and "Auto(Eco)" can be selected if "HDMI CEC" is set to
"On". If you select anything else, set "HDMI CEC" to "Off".
Power consumption in standby mode increases if set to anything other
than "Off".
"BD/DVD", "CBL/SAT", "GAME", "STRM BOX", "PC", "AUX", "CD", "TV",
"PHONO": For example, if you select "BD/DVD", you can play the equipment
connected to the "BD/DVD" jack on the TV even if the unit is in standby
mode. Select this setting if you have decided which player to use with this
function.
"Last": You can play the video and audio of the input selected immediately
prior to the unit being switched to standby on the TV. When "Last" is
selected, you can switch the input of the unit even in the standby mode with
the remote controller or the Onkyo Remote app.
"Auto", "Auto (Eco)": Select one of these settings when you have connected
equipment that conforms to the CEC standard. You can play the video and
audio of the input selected on the TV, irrespective of what input was selected
immediately prior to the unit being switched to standby, using the CEC link
function.
To play players on the TV that do not conform to the CEC standard, you
will need to turn the unit on and switch to the relevant input.
When using TV that complies with the CEC standard, you can reduce the
power consumption in standby mode by selecting "Auto (Eco)".
Audio TV Out
Default Value: Off
You can enjoy audio through the speakers of the TV while this unit is on.
"On": Use this function
"Off": Do not use this function
This setting is fixed to "Auto" if you have set "1. Input/Output Assign" ­ "TV
Out/OSD" ­ "HDMI Out" or "Other" ­ "HDMI Out" in the "Quick Menu" to
"MAIN" or "MAIN+SUB" and "HDMI CEC is set to "On". If you change this
setting, set "HDMI CEC" to "Off".
Listening mode cannot be changed while "Audio TV Out" is set to "On"
and audio is being output through the speakers of the TV.
Depending on your TV set or input signal of the component, audio may
not output through the speakers of the TV even if this setting is set to
"On". In such case, audio is output from the speakers of the unit.
If you operate the MASTER VOLUME dial on this unit when audio that is
being input through this unit for output from the TV speakers, audio is
output from this unit. If you do not want to output audio from the unit,
change the unit or TV settings, or reduce the volume of the unit.
