Key Digital just improved the KD-PRO2x1X (two input) and KD-PRO4x1X (four input) 4K/18G HDMI switchers with analog and digital audio de-embedding, auto switching, and app-based control.
Designed for conference rooms, huddle spaces, classrooms, theater and gaming spaces, KD-Pro2x1X and KD-Pro4x1X allows 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. The latest product release features TOSlink optical audio output, which has become of recent importance thanks to simplified sound bars with only TOSlink audio input connector. Alternately, integrating KD-Pro2x1X and KD-Pro4x1X with Key Digital’s KD-Amp220 model enables an app-ready all-in-one user-friendly solution for control of video switching with sound and speech enforcement.
KD-Pro2x1X and KD-Pro4x1X also feature front USB for setup using Key Digital Management Software Pro. With KDMS Pro, Integrators may apply network settings and names for the system, inputs, and outputs.
With Key Digital’s Auto-Sensing the KD-PRO2x1X and KD-PRO4x1X feature automatic selection of newly detected sources and switching from newly disconnected sources via Hot Plug Detection voltage when enabled.
KD-Pro2x1X and KD-Pro4x1X HDMI switchers support all SD, HD, VESA (VGA, SVGA, XGA, WXGA, SXGA, UXGA) and Ultra HD/4K video standards up to 4096×2160 or 3840×2160 24/25/30/60hz at 4:4:4 (signals up to 18Gbps bandwidth) with HDR header information included in a variety of 4K EDID handshakes. In addition to IR, RS-232, and TCP/IP control, KD-Pro2x1X and KD-Pro4x1X can also be controlled via trigger voltage and features status-monitoring LEDs.
The KD-PRO2x1X and KD-PRO4x1X are carefully licensed and compatible with HDCP 2.2.These switchers are HDR10 (High Dynamic Range) and Dolby Vision capable allowing for pristine image quality through a greater range of luminance levels. Deep Color is supported with ranges Up to UHD/4K 30Hz 4:4:4/12 bits or 60Hz 4:4:4/8 bit. Supported lossless compressed digital audio formats include Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio, and Dolby Atmos.
The KD-PRO2x1X and KD-PRO4x1X use advanced EDID controls, and come with a built-in internal library with15 EDID handshakes including 4K with HDR in addition to native EDID data copied from the output/display.
