Instruction manual and technical information

VAX04101 HDMI eARC Pass Switch 4×1

Dear customer,
Thank you for purchasing this high quality product. Please read these instructions before installation to ensure optimum use and safety. Please keep this manual for future reference.

Functions:

• HDMI switch for the operation of up to 4 HDMI sources on one HDMI sink (TV / projector)
• One HDMI input supports eARC (enhanced Audio Return Channel) and can be connected to the HDMI-eARC connector of a soundbar
• Audio EDID management
• Supports Ultra-HD up to 4K 60Hz as well as HDR10, HLG-HDR and Dolby Vision

Hint:
When changing the settings on the TV or Audio-EDID on the switch, please note that it may be necessary to restart the connected devices. If you do not obtain the desired output or  display, please proceed as follows:

• Switch on the desired Audio EDID mode on the switch and select the desired HDMI source.
• Disconnect all devices from the power supply for a few seconds, i.e. pull the power plug.
• Then plug in the power plugs and switch on the devices in the following order: TV, sound system, HDMI switch, HDMI source

Audio formats

The supported audio formats are negotiated between the devices. You can influence this using the EDID control (EDID = Extended Display Identification Data, this data identifies an HDMI sink to the HDMI source).
7.1
If set to 7.1 this allows the HDMI source to recognize that all audio formats are accepted. Please note that your sound system should support eARC to process all audio formats including Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, Dolby MAT and PCM7.1. If your sound system or TV is muted, they do not support the respective sound format.
5.1
If set to 5.1 the HDMI source is informed about the support of formats up to 5.1. These include Dolby Digital (AC3), DTS, PCM5.1 and PCM stereo. (If your sound system or TV remains mute, they do not support the respective sound format.)
2.0
If set to 2.0 the HDMI source will detect that only stereo is supported. Sound system and TV should therefore have sound in any case.
Auto
If set to Auto the switch does not interfere with the management of the sound format. Audio is automatically negotiated between source and TV.
Note: For some HDMI sources, you can manually adjust the audio output to override EDID negotiation. eARC is fully backward compatible to previous ARC protocol and supports further audio formats like Dolby TrueHD and Dolby MAT. Therefore you can connect both ARC and eARC devices. But your sound system requires eARC to receive advanced audio formats like Dolby TrueHD or Dolby MAT (Atmos from Apple TV).

Installation and Operation

• Connect 1 to 4 HDMI signal sources (e.g. Bluray player) to the HDMI inputs. Input 1 ARC to Sound is designed for connecting a soundbar with HDMI-eARC.
• Connect an HDMI sink (e.g. TV or video projector) to the HDMI output
• Connect the power adapter to the HDMI switch and plug it into an electrical outlet. Then turn on the TV / video projector, then the switch and an HDMI source.
• If a soundbar is connected, please active eARC by pressing the corresponding button

Caution: When plugging and unplugging the HDMI cables, take care not to dirty or damage the plug contacts. Make connections without power and only switch on the devices after  connecting them. Please also make sure that the HDMI cables are of good quality – especially for 4k transmission. Good cables usually have a large diameter. We recommend a maximum cable length of 5 m at the inputs and 3 m at the outputs for 4k HDR. For a longer cable run you can use a hybrid Fiber HDMI cable. Please make sure that HDMI-CEC and HDMI-eARC are supported by such cables!

Connections & Controls

1. LED lights up when automatic switching of the HDMI inputs is active*
2. LED of the selected HDMI input 1–4 is on
3. Short tap switches between the HDMI inputs, long tap activates Auto-Switching. If active, the device switches automatically to the last connected HDMI source. If you have  connected a soundbar and a television with HDMI-ARC, and eARC is switched on, you will hear the sound of the television when input 1 is selected.
4. LED of the selected audio EDID lights up, in Auto mode the EDID information of the connected HDMI sink (TV) is used
5. Switches between the audio EDID modes Auto/2.0/5.1/7.1
6. LED lights up when eARC is activated – must be active if a soundbar is connected.

8. Remote control infrared receiver window Instruction manual and technical information

Remote control

The supplied infrared remote control controls the same functions as the buttons on the front panel:

• With the red ARC key you can switch the eARC mode on or off
• Select between the audio EDID formats by pressing Auto / 2.0ch /5.1ch / 7.1ch
• Select the HDMI source using the buttons In1 to In4.
• Press Auto Source to switch automatic switching of the HDMI inputs on or off.*

*Please note that many media players such as Apple TV or Fire TV do not support automatic switching because the signal outputs are not switched off in standby. Switching via HDMI CEC command is not possible because there is no connection to non-active HDMI sources.

1. HDMI inputs 1 to 4, please use ARC to Sound 1 for the connection of a soundbar
2. HDMI output for the connection of a TV or video projector – HDMI-ARC is supported
3. Micro-USB connector for service
4. Connector for the DC plug of the mains adaptor

Scenarios

1. Playback from HDMI source, sound via sound bar in 5.1 or 7.1 format
   Switch on eARC and select the sound format 5.1 or 7.1 (Dolby Atmos) at the switch. Then select the desired HDMI source at input 2, 3 or 4. Note: Parallel sound output via the television is also possible.

2. Playback of the TV sound (Sat/CATV or Apps) via the soundbar
   Switch on eARC at the switch and select input 1 (ARC to Sound). Activate HDMI- ARC on the TV if not already done. Please make sure that the TV is connected with its HDMI- ARC port to the switch and the HDMI cable supports ARC.

3. Use as a normal HDMI switch
   Switch off eARC. Then select the desired HDMI source 1 to 4. If there are other sources connected to your sound bar via HDMI, they can be played. If available, you can access  the sound bar menu this way.

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 T V, 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 T V apps or cable/satellite T V 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 necessar y. Connect the video projector to the TV output of the VA X04101.

My soundbar or its app gives an error message that no TV with HDMI-ARC is connected, e.g. Sonos S2 “connection error”. What can I do?

• The Soundbar is connected to the VAX04101 and therefore a T V is neither necessar y nor recognisable. 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 ever ything automatically with the T V 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 of f 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 of f eARC on the VAX04101?

• You only need to switch of f eARC if you are operating a soundbar with several HDMI inputs and another HDMI source is to be played there.
