5.1 Manual or automatic switching

The Connect 621 UHD 2.0™ allows you to choose which HDMI
source is displayed on the TV. If you turn on one of the HDMI
sources, it will automatically switch to the correct input. If multiple
HDMI sources are turned on, the Connect 621 UHD 2.0™ will
automatically switch to the HDMI source that was activated last. To
activate or deactivate the AUTO feature, press and hold the AUTO
button on either the remote control or the front panel, until the
corresponding light switches on or off respectively. If you want to
manually select another HDMI source, please use the
corresponding button on the remote control or the "Input" button at
the front.
Note: Automatic switching must be supported by the HDMI source.
If it is not supported, you should manually select the appropriate
HDMI source.

5.2 Audio settings

Select the desired audio settings by using either the remote control or the front buttons
of the Connect 621 UHD 2.0™.
5.2.1

Audio Return Channel

If your AV amplifier is connected via the "Audio out", there may be a slight lag between
your TV's image and the sound coming from the AV amplifier. This is caused by image
processing on your TV and is sometimes referred to as lip sync problem. The Connect
621 UHD 2.0™ supports ARC (Audio Return Channel). This involves the sound first
being sent to the TV, and then returned by your TV at exactly the right moment, using
the same HDMI cable. This allows you, without the use of additional wiring or settings,
to synchronise images and sound. The "ARC" switch allows you to enable or disable
this feature.
ARC must be supported by your TV to be able to use this feature. If your TV does not
support ARC, you can either turn off image processing on your TV, or delay the audio
coming from your AV amplifier or HDMI source. Please refer to your device's manual
for the correct settings.
