Frequently asked questions and answers
How do I connect a soundbar for Dolby Atmos that has only one HDMI-eARC connection?
• Connect the HDMI connection of the soundbar to HDMI input 1 of the VAX04101. Connect
the TV output of the VAX04101 to your TV, monitor or video projector. Switch on eARC on the
VAX04101 and select EDID 7.1. You usually do not have to change these settings.
I want to hear the sound from Smart TV apps or cable/satellite TV through the soundbar. What do
I need to set?
• Switch on the audio output on the TV via eARC or ARC. Select input 1 on the VAX04101. eARC
must be switched on on the VAX04101.
My video projector does not have a connection with HDMI-ARC. How do I connect it?
• An ARC or eARC connection is not necessary. Connect the video projector to the TV output of
the VAX04101.
My soundbar or its app gives an error message that no TV with HDMI-ARC is connected. What can
I do?
• The Soundbar is connected to the VAX04101 and therefore a TV is neither necessary nor rec-
ognisable. Please ignore this message. You can still set up your system by wiring the devices.
Please exit a dialogue-based installation.
I want to control everything automatically with the TV remote control. How can I do this?
• Media players such as Apple TV or Fire TV can only be controlled or operated automati-
cally if there is an active connection between the TV and the media player. The VAX04101
must therefore be switched to the connection from the Apple TV (with the VAX04101 remote
control or on the HDMI switch). If the VAX04101 is switched to another input, it is no longer
possible to control the Apple TV. Automatic switching to the HDMI input works with HDMI
sources that are inactive or completely switched off in standby. Automatic device control via
the VAX04101 is therefore somewhat limited compared to a direct HDMI connection to the
TV when several HDMI sources are used.
When do I have to switch off eARC on the VAX04101?
• You only need to switch off eARC if you are operating a soundbar with several HDMI inputs
and another HDMI source is to be played there.
