KATCH ONE – HDMI Setup Guide
3 | 4
The timing of when a TV activates/deactivates the optical signal varies between the different TV
manufacturers and models. KATCH ONE will power on as soon as the signal carrier is activated, and it will
power off 20 minutes after the signal carrier has been deactivated and no other user actions have been
performed or input signals applied.
Using TV with AUX IN
If your TV does not support HDMI-ARC and it does not have Optical Audio out, then it is also possible to
connect an Analog Audio out from the TV to KATCH ONE. But please note that HDMI-CEC is not enabled for
AUX IN. Depending on the type of Analog Audio out from the TV, you might have to experiment with
adjusting the volume both from the TV and KATCH ONE . Avoid adjusting either TV or KATCH ONE to
extreme levels.

Disconnect any other Audio equipment connected to the TV
Disconnect any Optical audio cables from the TV (make sure the cable is disconnected from the TV
itself)
After disconnecting any equipment, power off and on again the TV, and test if KATCH ONE is now
working.
If it now works with other equipment disconnected, then reconnect other equipment one at a
time, and identify the specific equipment breaking the functionality.
If you are unable to solve HDMI ARC related issues with your specific setup (TV + other connected
equipment), then consider using an Optical connection for Audio Out from your TV to KATCH ONE.
My system has been working, but it suddenly stopped, and/or it sometimes works and sometimes not
In most cases, a temporary issue can be solved by powering the TV off and on again.
As powering off and on the TV can be time-consuming, KATCH ONE itself also provides two methods for re-
initializing the HDMI connection. When KATCH ONE is powered on and HDMI is selected as source, then
you can try one of the following:
