Introduction
Key Digital
®
KD-Pro2x1X/KD-Pro4x1X are 4K/18G HDMI switchers 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, KD-Pro2x1X/
KD-Pro4x1X 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. Integrating KD-Pro2x1X/KD-Pro4x1X with KD-Amp220
will enable an app-ready all-in-one solution for control of video switching with sound and speech
enforcement. KD-Pro2x1X/KD-Pro4x1X HDMI switchers support 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-Pro2x1X/KD-Pro4x1X can also be controlled via trigger voltage and
features status-monitoring LEDs.
