Key Digital Adds HDMI HDBaseT Extender Kit

Key Digital has introduced the KD-X444S extender kit ideal for residential installations requiring extension of HDMI signals up to 18 Gbps via a single CAT5e/6. The HDCP2.2 compliant KD-X444S HDBaseT Tx and Rx kit feature a low-profile, slim-chassis design with support of all of the latest HDMI standards.

KD-X444S features support of HDR10 (High Dynamic Range) video through a greater range of luminance levels. The KD-X444S extends UHD / 4K (4096×2160 / 3840×2160 24/25/30/60hz) resolutions at 4:4:4 with bandwidth up to 18 Gbps and audio formats up to Dolby TrueHD, Dolby Digital Plus, Dolby Atmos, and DTS-HD Master audio up to 40m (130 ft) using CAT5e/6 cabling. 1080p resolution is extended up to 70m (230 ft) with CAT6 cabling.

The KD-X444S features fully automatic adjustment of feedback, equalization, and amplification depending on cabling length so integrators no longer need to fine tune equalization knobs for each display. The extender set features flexible power over HDBaseT with only one power connection needed with the Tx providing power to the Rx or the Rx powering the Tx.

Full Buffer System manages TMDS re-clocking, signal re-generation, HDCP authentication with source and display, EDID Control handshake, and Hot Plug Detection control. Integrators have the choice of handshake delivered to the connected video source. Key Digital boasts an internal library with 15 EDID handshakes including an update to 4K handshakes which includes HDR Header information. Additionally, the native EDID data from the connected Output/Display device may be provided to the video source.

In addition to HDMI video and audio signals, KD-X444S carries IR and RS232 for controlling remotely located equipment. IR sensor powering via +5V on IR In ports collects line-of-sight IR from remotes without external IR connecting block. Two channels of IR and bi-directional RS232 enable control to/from devices or control systems connected to Tx and Rx units. CEC Pass-thru for inter-device control between input and output HDMI channels is also supported.
