Step 3  Connections
≥Turn off all equipment before connection and read the appropriate owner’s manual.
Do not connect the AC power supply cord until all other connections are complete.
∫HDMI
The HDMI connection supports VIERA Link “HDAVI Control” (>25) when used with a compatible Panasonic TV.
≥Use the High Speed HDMI Cables. It is recommended that you use Panasonic’s HDMI cable.
Recommended part number (High Speed HDMI cable):
RP-CDHS15 (1.5 m/4.9 ft), RP-CDHS30 (3.0 m/9.8 ft), RP-CDHS50 (5.0 m/16.4 ft), etc.
≥Non-HDMI-compliant cables cannot be utilized.
Verify if the TV’s HDMI terminal is labeled “HDMI (ARC)”.
∫What is ARC?
ARC is an abbreviation of Audio Return Channel, also known as HDMI ARC. It refers to one of the HDMI functions. When you 
connect the main unit to the terminal labeled “HDMI (ARC)”, the optical digital audio cable that is usually required in order to 
listen to sound from a TV is no longer required, and TV pictures and sound can be enjoyed with a single HDMI cable.
Make the connection.
Connection with the TV
Connection differs depending on the label printed next to the HDMI terminal.
Labeled “HDMI (ARC)”: Connection [A]
Not Labeled “HDMI (ARC)”: Connection [B]
[A] Labeled “HDMI (ARC)”

You can direct the audio signal from the connected Blu-ray Disc playerTM, DVD player, Set Top Box, etc. 
to this system.
Preparation
≥Connect the main unit to the TV (>19).
∫HDMI standby pass-through
Even if the main unit is in standby mode, the audio and/or video signal from the device connected to the BD/DVD or AUX1 
terminal will be sent to the TV connected to the HDMI OUT terminal (the sound will not be output from this system). When 
devices are connected to both BD/DVD and AUX1 terminals, audio and/or video signal of the device whose input is lastly 
selected is output.
∫3D compatibility
Compatible with FULL HD 3D TV and Blu-ray Disc playerTM.
≥The main unit can pass the 3D video signal from a 3D compatible Blu-ray Disc playerTM to a FULL HD 3D TV.
