Key Digital® KD-Pro4x1X-2 is a 4K/18G HDMI switcher with analog and digital audio de-embedding, auto switching, web UI and iOS app-ready control. Designed for professional audio video installations in conference rooms, huddle spaces, classrooms, theater and gaming spaces, KD-Pro4x1X-2 enables multiple video sources to connect to a single video display while 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. 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 boasts a programming-free presentation system capability when integrated with KD-Amp220 and/or KD-CamUSB and controlled via Web UI or free Key Digital iOS app.
