Matrix HDMI selector switch with audio of 5 inputs 1 output and remote control
- HDMI port selector. It has four female HDMI input ports, one of which is selected as an active port by means of a button on the device itself or remotely with a remote control.
- Amplifier for each HDMI input or output port, since it allows 15 m of cable in each port. This makes a total of up to 30m of HDMI cable from the video source to the display. The final distance depends on the quality of the cable and the environment.
- Matrix selector that allows multiple video sources to be displayed on the same TV screen. It allows different display configurations (1, 2, 3 and 4 sources).
- Active audio selector. Allows selection of the active audio channel, which is drawn from any of the HDMI video input sources.
- Compact and small size model (190 x 91 x 25 mm).

HDMI (High-Definition Multimedia Interface) is a digital interface standard designed for the simultaneous transmission of uncompressed audio and video streams from a compatible source to a digital display or receiver.
This interface employs Transition-Minimized Differential Signaling (TMDS) to maintain data integrity at high frequencies. Throughout its revisions, HDMI has evolved from a basic digital video solution into a complex data bus capable of carrying 4K signals at 60Hz, dynamic metadata, and bidirectional control protocols between devices.
| Version | Bandwidth | Audio/Video Support |
|---|---|---|
| 1.0 - 1.2 | 4.9 Gbit/s | 1080p @ 60Hz, 8 LPCM channels |
| 1.3 - 1.4 | 10.2 Gbit/s | 4K @ 30Hz, Deep Color, ARC, Ethernet |
| 2.0 | 18.0 Gbit/s | 4K @ 60Hz, 32 audio channels, HDR |
The mass adoption of the HDMI standard has transformed the interconnect architecture in multimedia data centers and high-performance workstations. Its ability to integrate Audio Return Channels (ARC/eARC) and Ethernet connectivity (HEC) has drastically simplified structural cabling, eliminating the need for multiple redundant analog and digital cables while ensuring signal integrity over significant distances through active equalization.
CEC Control and Multi-Streaming Integration
A critical innovation in version 2.0 is the ability to deliver simultaneous dual video streams on the same screen and up to four independent audio streams, optimizing bandwidth for multi-user applications.
Key Advantages
- Pure digital transmission avoiding D/A signal degradation.
- Full backward compatibility across all standard versions.
- Native support for high-resolution audio formats like Dolby TrueHD and DTS-HD.
- Support for 21:9 cinema aspect ratios and dynamic lip-sync.
Note: Final interface performance is dependent on the cable certification (Standard, High Speed, or Premium High Speed).
