Key Digital KD-Pro4x1X-2 4 Input Pro Series HDMI Auto Switcher with Web UI

Key Digital KD-Pro4x1X-2 is a 4K/18G HDMI switcher with analog and digital audio de-embedding, auto switching, and app-ready controllability. Designed for professional audio video installations in conference rooms, huddle spaces, classrooms, theater and gaming spaces, it enables multiple video sources to connect to a single video display. Analog (3.5mm & balanced/unbalanced) and digital (optical & PCM) audio de-embed ports may feed audio of the selected source into and amplifier, DSP, or sound bar. Integrating KD-Pro4x1X-2 with KD-AMP220 will enable an app-ready all-in-one solution for control of video switching with sound and speech enforcement. KD-Pro4x1X-2 supports all SD, HD, VESA and Ultra HD/4K video standards with HDR header information included in a variety of 4K EDID handshakes. In addition to IR, RS-232, and TCP/IP control, KD-Pro4x1X-2 can also be controlled via trigger voltage and features status-monitoring LEDs.
