About ARC and CEC
Note that the default setting for ARC (Audio Return
Channel) is Off. To use ARC, it must be set to On.
Turning HDMI Control On will also enable ARC.
HDMI Control enables CEC (Consumer Electronics
Control) commands to be transmitted over the HDMI
cable so your television and MX123 can better
communicate. ARC and HDMI Control (CEC) is
factory defaulted to Off because the world of ARC
and CEC is not yet perfect. It is certainly getting
better, but not every component in the world is
speaking precisely the same language. These features
can be enabled or disabled at any time on the MX123.
See HDMI Setup on page 21. Remember to enable
CEC on your television if you want to use CEC with
the MX123.
HDMI Control (CEC) should also be set to Off, if you
are using a third-party control system so that CEC
does compete with your external controller.
The ARC feature, when enabled, will work with the
TV Audio input and a television connected to the
HDMI Monitor 1 (ARC/eARC) Output.
eARC
allows
for even higher bandwidth and will allow for higher
quality audio including uncompressed 7.1 surround,
Dolby Atmos and DTS:X.
