About KD-PS42
Key Digital® KD-PS42 is a 4K/18G KD-
App Ready Presentation Switcher kit with CEC Manager™, auto
switching, and audio de-embedding creating a user-friendly, simplified presentation system. KD-PS42 features

Mirrored HDMI and HDBaseT outputs enable au presenter views and the HDBaseT output marries in
with the included KD-X40MRx for integrating monitors or projectors up to 40m / 131ft away when the selected
source is outputting 4K/UHD (up to 70m / 230ft at 1080p).
Designed for professional audio video installations in conference rooms, board rooms, classrooms, lecture
halls, auditoriums, and more, KD-PS42 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-PS42 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-PS42 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
