The company continues its HDMI product expansion with the introduction of its state-of-the-art KD-HDMI2x4P.
January 07, 2007 by Rachel Cericola

The KD-HDMI2x4P is an HDMI (with HDCP) two-input switcher to four-output distribution amplifier that handles all digital HDTV and SDTV video switching and distribution needs including 1080p/60, plus a wide variety of analog and digital audio formats.

View more of our CES special coverage HDMI is everywhere, as more and more video and audio products support this all-digital, plug-and-play interface. So many products support HDMI, like DVD players, set-top boxes and displays. Key Digital engineered the KD-HDMI2x4P to switch two HDMI sources to four separate HDMI displays and a variety of audio systems.

The KD-HDMI2x4P is ideally suited to select either of two favorite HDMI or DVI-D source devices (DVI-D compatible with Key Digital adapters and cables), like your DVD player, HD DVR, etc., to up to four displays with an HDMI or DVI-D input. It handles all frame rates (like 50, 60, and 72 Hz) and clock rates up to 165MHz, all the way up to 1080p/60 resolution.

It also allows you to select either SPDIF audio (derived from the audio that can be present on the selected HDMI source input), Toslink optical audio input converted to digital PCM audio, digital PCM audio, or analog left and right stereo audio. Drive up to four HDMI-enabled displays and audio systems, with each totally independent output carrying the same identical signal as the input.

  • Push-button controls
  • Status-monitoring LEDs
  • IR remote control
  • Auto-select switching of the active HDMI source input
  • Cascade and daisy-chain multiple units
  • Up to eight units individually addressable in the same room
