Kd2600 is a large-scale matrix switcher in the simulation matrix series of Dalian Kedi Company. The matrix size of Kd2600 ranges from 24 × 24 to 512 × 512, including over a hundred models, supporting composite video and stereo audio (balanced and unbalanced). All technical indicators exceed the national broadcast level standards, and the technical level is in an absolute leading position in China.

Compared with other matrix switches in the AV industry, the design method of Kd2600's "modular design, plug-in structure, and hot standby dual power supply" is unique and consistent with the design methods of internationally renowned brands. The so-called "modular design, plug-in structure" refers to independent wiring between circuit boards, and all circuit boards in the system support hot swapping, with high isolation and strong anti-interference ability. When the matrix malfunctions, simply replace the faulty circuit board, which brings great convenience to system maintenance and expansion. "Hot backup dual power supply" refers to the system having two power sources supplying power equally at the same time. When one power source encounters a problem, the other power source can immediately support the system's normal operation, ensuring that the system has no power hazards.

The Kd2600 large AV matrix switcher adopts field reverse switching throughout the switching process, with almost no jitter during switching. The matrix has an RS-232 interface for cascading expansion, and supports multiple remote control panels or control software for remote control. The host of the matrix system has a power-off memory function, ensuring that data is never lost after a power outage. The video switching input AC/DC recovery method is optional, and the output uses a video high-speed operational amplifier to ensure image signal quality. The circuit adopts a transformer free balanced output to ensure excellent common mode suppression ratio, with wide frequency response and low distortion characteristics.

At present, models such as 64 × 64, 96 × 64, and 128 × 128 in the Dalian Kodi Kd2600 large AV matrix switcher have been widely used in various fields of engineering. Among the large matrix products in China, the Kd2600 series not only has extremely high performance, but its price is also lower than that of many domestic and foreign brands, and it has an absolute competitive advantage in the market.
