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 and balanced/unbalanced) and digital (optical and PCM) audio de-embed ports may feed audio of the selected source into an 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.

Rack Mounting
KD-Pro4x1X-2 includes a half-rack blank and a standard short rack ear for mounting in a standard-with rack. If you wish to mount two units side by side you may do so with optional KD-BKTHF.
