First, the principle of audio and video matrix switcher: An audio and video matrix switcher is a specialized device designed to route and distribute both video and audio signals. It allows multiple input signals to be switched to any output channel, with each output operating independently. The product ensures synchronized or asynchronous control of both visual and audio signals. Equipped with power-off field protection and reverse-switching features, it supports online operation through RS-232 communication, infrared control, and network control. The switcher uses an advanced LED panel display and touch buttons for a more intuitive and user-friendly interface, making it easier to monitor and operate.
Second, audio and video matrix switcher interfaces: Typically, the interface consists of a white audio port and a yellow video port, commonly connected via RCA connectors (often referred to as "lotus heads"). To use it, simply connect an RCA cable with lotus heads to the corresponding ports. While this setup enables separate transmission of audio and video signals, it still transmits a composite Y/C signal. This means that the display device must perform color separation and chrominance decoding, which can lead to color signal loss and interference between luminance and chrominance signals. As a result, image quality may be compromised. Although the system has some advantages, its inherent limitations in Y/C mixing prevent it from being used in high-end applications where optimal visuals are required.
Third, key features of the audio and video matrix switcher: 1. Utilizes the latest ARM9 embedded processor for efficient performance. 2. Incorporates a 300MHz high-bandwidth professional chip to support HDTV signals. 3. Implements long-distance transmission distortion gain compensation technology, supporting up to 300 meters. 4. Features a professional audio op-amp post-processing chip for rich and natural sound. 5. Equipped with a blue LCD display showing all information in Chinese for easy monitoring. 6. Uses programmable logic circuits (FPGA) for stable and clear functionality. 7. Applies full SMD process with built-in ESD protection for enhanced durability. 8. Audio and video input/output terminals use RCA interfaces for compatibility. 9. Supports N-channel video input and output, enabling full cross-switching. 10. Offers N-channel stereo audio input and output, supporting synchronous or asynchronous switching. 11. Includes a round-robin switching function with customizable timing and channel selection. 12. Built-in 8 scene memory functions for quick access directly from the panel. 13. Compatible with industry-standard codes and commands for seamless integration. 14. Features power-off memory protection to preserve settings during outages.
Fourth, control modes of the audio and video matrix switcher: 1. Button control: Directly switch channels using the panel buttons and view the status. 2. Infrared remote control: Operate the switcher remotely using an infrared remote. 3. Matrix management software: Use the proprietary MCONSW1.0 software for advanced control via RS232 or TCP/IP. 4. Touch screen or panel control: Connect a programmable touch screen (MCON-TCH880) or panel (MCON-OPP2000) for plug-and-play operation. 5. Centralized control: Integrate with other systems and control devices for comprehensive management.
Fifth, application areas: The audio and video matrix switcher series is a high-performance, intelligent device used to route audio and video signals synchronously or asynchronously across multiple channels. It is widely used in large-screen projection systems, lecture halls, command centers, and multimedia conference rooms, offering flexible and reliable signal management.
