KD-UPS52U
Key Digital®KD-UPS52U is a 4K/18G KD-App Ready universal presentation switcher + soft-codec
enabling interface with CEC Manager™, auto switching, and audio de-embedding creating a user-
friendly, simplified presentation system. KD-UPS52U features two HDMI, 1 Display Port, one USB-C,
and one HDBaseT input which integrates natively with universal presentation + USB switching wall plate
transmitter, KD-X4x1WUTx (sold separately). KD-UPS52U also features two USB-A and one USB-B
connectors, enabling connected laptops and computers to connect with web cams, USB microphones,
touchscreen displays, conferencing DSPs, and more. Mirrored HDMI and HDBaseT outputs enable
audience + presenter views and the HDBaseT output marries in with the included KD-X100MRx for
integrating monitors or projectors up to 100m / 328ft away when the selected source is outputting 4K/
UHD (up to 150m / 492ft at 1080p). Designed for professional audio video installations in conference
rooms, board rooms, classrooms, lecture halls, auditoriums, and more, KD-UPS52U enables multiple
video sources to be displayed on up to two connected displays while analog (balanced/unbalanced) and
digital (PCM) audio de-embed ports feed audio of the selected source into an amplifier, DSP, or sound
bar. Integrating KD-UPS52U with KD-AMP220 and KD-CAMUSB will enable an app-ready all-in-one
solution for control of video switching, sound and speech enforcement, and PTZ camera control. Key
Digital CEC Manager™enables basic controls of the connected displays for a simplistic
all-in-one integration system. KD-UPS52U presentation switcher 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-UPS52U can
also be controlled via trigger voltage and features status-monitoring LEDs.
