5.3.1

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 referred to as lip sync problem. The Connect 642 Pro™
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.

5.4 1080p downscaler

To ensure the highest quality being used when two different resolution displays are
connected to the Connect 642 Pro™, the matrix switch can use the build-in 1080p
downscaler. This function makes it possible to downscale an UHD video format to fit on
a 1080p resolution screen. This way the lower resolution screen can show the image
without the high resolution screen losing its high quality image.
To enable this feature, press the 'downscale' button[4], on the front or on the remote, to
select the output that will be downscaled.
