Key Digital Launches Updated KD-Pro4x1X-2 HDMI Switcher
KD-Pro4x1X-2 4x1 UHD/4K/18G HDMI switcher allows auto switching, audio de-embedding,
status-monitoring LEDs, and numerous control options
Key Digital launched the second-generation KD-Pro4x1X-2: a 4x1 UHD/4K/18G HDMI
switcher with 4x1
auto switching, audio de-embedding and a plethora of control options. "For applications ranging from
conference rooms to huddle spaces, classrooms, theatre, and gaming spaces, the KD-Pro4x1X HDMI
switcher is a core tool for many of our customers, says DeWayne Rains, Key Digital VP of
sales. "The
updates to the KD-Pro4x1X-2 ensure the availability of this affordable solution into the future."
In addition to auto-switching that, when enabled, automatically selects a newly detected source, or
switches away from a newly disconnected source, the KD-Pro4x1X-2 offers front-panel-button, IR,
RS-232, TCP/IP and trigger voltage control, and features status-monitoring LEDs. The KD-Pro4x1X-2
also offers integrated web UI control from any browser on any networked device for a complete
control solution that includes AV switching via IP, KD-Amp220 audio with microphone mix via RS-232,
and KD-CamUSB PTZ web cam control via RS-232. CEC control is passed through from the selected HDMI
source to the connected display.
To flexibly feed amplifiers, DSP processors and sound bars, the KD-Pro4x1X-2 delivers audio
de-embedding in both analog (two-channel on a 1/8-inch [3.5mm] jack and balanced/unbalanced outputs
on a six-pin terminal block with support for sampling rates up to 192 kHz) and digital (optical &
SPDIF with surround audio support including DTS-HD Master Audio, DTS:X, Dolby TrueHD and Dolby Atmos
at sampling rates and channel counts up to 96 kHz/7.1).
The KD-Pro4x1X-2 supports all SD, HD, VESA and Ultra HD/4K video standards with resolutions up to up
to 4096x2160 or 3840x2160 24/25/30/60hz at 4:4:4. Standards and protocol support further includes
Dolby Vision, HDR10, fully licensed HDCP 2.2 compatibility, deep colour support up to UHD/4K 30Hz
4:4:4/12 bits or 60Hz 4:4:4/8 bit and a full buffer system that manages TMDS re-clocking / signal
re-generation, HDCP authentication to source and display, and EDID Control handshake. EDID
management utilizes an internal handshake library in addition to native EDID data copied from the
output/display.
