• If HDMI Control does not work properly, try unplugging the TV in Step 3 and plugging in the TV again in Step 4.
It may solve the problem. Also, HDMI Control may not work if the number of connected devices exceeds the
limit. In this case, disable HDMI Control on the devices not in use.
• If the unit is not synchronized to the TV’s power operations, check the priority of the audio output setting on
the TV.
• We recommend using TV and playback devices from the same manufacturer so that HDMI Control works more
effectively.
• We do not assure the operation of all HDMI Control-compatible devices.
Audio Return Channel (ARC)
ARC allows you to input TV audio to the unit with the HDMI cable which transmits video signal
to the TV.
Check the following after the HDMI Control settings.
1
Select a TV program with the TV remote control.
2
Check that the input source of the unit will be automatically switched to
“AUDIO 1” and the TV audio will be played back on the unit.
If you cannot hear the TV audio, check the following:
• “ARC” (p.151) in the “Setup” menu is set to “On”.
• The HDMI cable is connected to the ARC-compatible HDMI jack (HDMI jack marked
“ARC”) on the TV.
Some HDMI jack on the TV is not compatible with ARC. For details, refer to the instruction
manual for the TV.
Y
• If the audio is interrupted while using ARC, set “ARC” (p.151) in the “Setup” menu to “Off” and use an
audio cable (digital optical or stereo pin cable) to input TV audio to the unit (p.43).
• When using ARC, connect a TV with an HDMI cable that supports ARC.
X
“AUDIO 1” is set as TV audio input at the factory. If you have connected any external device to the AUDIO
1 jacks, use “TV Audio Input” (p.151) in the “Setup” menu to change the TV audio input assignment. To use
the SCENE function (p.77), you also need to change the input assignment for SCENE 2.
HDMI signal compatibility
• When CPPM copy-protected DVD-Audio is played back, video/audio signals may not be
output, depending on the type of the DVD player.
• The unit is not compatible with HDCP-incompatible HDMI or DVI devices. For details, refer to
the instruction manual for each device.
• To decode audio bitstream signals on the unit, set the input source device appropriately so
that the device outputs the bitstream audio signals directly (does not decode the bitstream
signals on the playback device). For details, refer to the instruction manual for the playback
device.
