The KanexPro HDMMX1616-4K is a sixteen input by sixteen output modular matrix switcher chassis with four input slots and four output slots; each modular input or output card supports up to four device connections. As an add-on to front panel control, the HDMMX1616-4K can be controlled via IR, RS232, or TCP/IP connections. The optional modular input cards include the following connections: HDMI, DVI, VGA, HDBaseT (with RS232 and bi-directional wide-band IR), Fiber Optic and analog video with digital scaling via HD15 (VGA-UXGA, RGBHV, RGBS, RGsB, RsGsBs, component video, S-video and composite video). The modular output cards include the following connections: HDMI, SDI, DVI, VGA, HDBaseT and Fiber Optic. Stereo audio embedding is supported on the HDMI input cards to allow analog audio to be inserted into the digital signal. Stereo audio can also be de-embedded using the HDMI or HDBaseT output cards. Advanced EDID management restricts sources to output only stereo audio, while emulating the native video data from the attached displays. This system allows analog audio to be switched with the paired digital video, eliminating the requirement for an additional audio matrix switcher. The clear button caps provide readable text on the front panel, which can be customized for each installation. Control via IR, RS232, and TCP/IP provide a wide range of options for third party control systems. Ten programmable presets provide an efficient means of configuring the video and audio distribution for common usage patterns. Applications Ideal for various commercial applications such as, control centers, smart lecture halls, medical and government facilities and residential environments where 4K UHD signal distribution and audio is critical.Features: Customizable 16x16 modular switch serving various AV connections 4K UHD resolution via HDMI & HDBaseT Supported connections: VGA, SDI, DVI, HDMI, HDBaseT & Fiber optic High-bandwidth up to 10.2 Gbps Add I/O modular cards based on expandability Cross-point ultra-switching Advanced HDCP & EDID management Hot swappable design Clear illuminated buttons Control via IR, Ethernet & RS-232 10 global presets Front panel LCD for switching & status Front panel security lock 3 RU rack-mountable aluminum enclosure Dual-Internal power supply (100Volt~240Volt AC, 50/60Hz) Backed by KanexPro 3-Year full parts & labor warranty
