6.9.3. HDMI
ARC
If you want to use a TV set as a signal receiver AND signal source (to transmit an au-
dio signal to an audio receiver), use an HDMI port with audio return channel (ARC).
The HDMI connection to the TV then works in both directions. It can receive image
and sound signals from a video device and the audio signal of the TV set can also be
sent to the audio receiver via the audio return channel.
Connect the video device (e.g. Blu-ray player) to the audio receiver via HDMI.
Connect the audio receiver to the TV set via HDMI/ARC.
Take care to ensure that the speaker control of the TV set is routed to the exter-
nal amplifier.

CEC

standby or record functions):
Connect all devices via CEC-enabled HDMI ports with HDMI cables.
Take care to ensure that the CEC functions are enabled for all ports and that all
devices are connected accordingly.
6.9.5. USB
A USB port can be used to connect and read storage media such as USB sticks or ex-
ternal hard drives. Use a suitable USB cable. If a suitable USB cable is supplied, you
should use this (e.g. for hard drives).
Connect the corresponding USB ports of the devices used with a suitable USB
cable. Whenever possible, do not use a USB extension cord as this can cause
problems, depending on the voltage.

multi-channel audio signals between various devices. Usually, the digital audio sig-
nal is output via a coaxial (cinch) or an optical connection. Use a suitable standard
cable.
