introduction

Key Digital’s KD-DA2x4G and KD-DA2x8G are 18Gbps and HDCP2.2 supporting HDMI Switcher + Distribution Amplifier kits with HDBaseT output and 4/8 Rx units included. The KD-DA2x4G/KD-DA2x8G kit is designed for applications such as Digital Signage and other professional AV installation types, where the selected HDMI source is distributed to up to 4/8 displays. All connected displays show the same image at the same time. The 4/8 KD-XDALRx HDBaseT Rx extenders are all powered via HDBaseT from the KD-DA2x4G/2x8G unit, and support extension of resolutions up to UHD/4K up to 250 ft. (76m) using CAT5e/CAT6/CAT6A/CAT7. 1080p resolutions may be extended up to 328 ft. (100m). KD-DA2x4G/KD-DA2x8G is easily integrated into professional AV systems with the audio from the selected source being de-embedded on analog and digital audio connectors, and switching controllable via TCP/IP, RS-232 or IR. KD-DA2x4G/KD-DA2x8G is Key Digital App ready and also controllable by control systems such as Compass Control Pro. EDID handshaking is easily selected via front panel rotary dial and all UHD/4K EDID handshake files include HDR header information.
