VMS14201 HDMI 2.1 Matrix Switch 4x2 with Audio Extractor

Purpose:

• Allows you to connect 4 HDMI sources such as a PC, PS5 or Xbox Series X game console to 2 HDMI sinks, e.g. a TV and a video projector
• Audio Extractor for the separate output of the sound from one of the 4 players or from the TV via HDMI-ARC
• Mixed operation with a 4K and a full HD display possible (automatic downscaler)
• Management for the audio EDID
  

Functionality:

With this switch, 4 players can be used on 2 displays, e.g. television and monitor. This allows you to play one of the 4 players on both displays at the same time, or have a different player shown on each display.

HDMI audio extractor

The integrated audio extractor outputs the sound of a selected player via the optical digital output (in stereo, Dolby Digital 5.1 or DTS 5.1) and via RCA cinch (stereo only). You can connect a sound system or a headphone base station there. The HDMI signal at output A and B for televisions is not changed, it includes also sound. If ARC is switched on at the Matrix Switch, the internal sound from TV B can also be output via Toslink. ARC stands for Audio Return Channel, a suitable connection can be found on most televisions and only rarely on a video projector.

Downscaler

So that a 4K and a full HD display can be operated at the same time, the Switch has an automatic downscaler. The 4K video signal is thus converted to 1080p reduced resolution for the Full HD device. At the same time, the 4K device receives the original signal. The frame rate is not changed. A maximum of 4K 60Hz can be scaled down, 1080p 60Hz is then output on the Full HD TV. The downscaler is therefore inactive for 4K 120Hz gaming.

Gaming in 4K

All new gaming features like 4K 120Hz and VRR are supported. In order for an HDMI 2.1 transmission to be possible, e.g. 4K 120Hz for gaming, both connected HDMI displays must support HDMI 2.1. A mixed operation
possible with HDMI 2.0 is not possible, not even for HDMI audio only.

Dolby Vision / HDR10+ / 3D video

In order for a player to output these video formats, both  connected displays must support this. For example, if the TV on output A supports Dolby Vision, the Projector at output B but not, the output is in HDR10 or SDR (depending on the player).

EDID mode

Select PASS if you are not using the audio outputs on the switch. With the A/B button you choose whether to use the maximum audio format of the device at output A or B. If, for example, a television with a soundbar is operated at output B,
you should select B. The LED A/B then does not light up. If the "better" sound system is connected to output A, press the A/B button on the switch for 3 seconds or uses the DOWN button on the remote control. The LEDs A/B and PASS then light up. In the 5.1 setting, the audio format is limited to Dolby Digital / DTS, so that it can always be output via the Toslink port. In the 2.0 position, stereo is supported for output via RCA.

You can press the button on the remote control or on the matrix switch to select between the 4 inputs. Automatic switching is not possible. Power is supplied via the supplied mains adaptor.
