About the DA2 HD 4K, DA4 HD 4K, and DA6 HD 4K
The Extron DA HD 4K Series are one input, multiple output HDMI distribution amplifiers for 4K
signals. They distribute one 4K input signal to two (DA2 HD 4K), four (DA4 HD 4K), or six
(DA6 HD 4K) simultaneous outputs. They support data rates up to 10.2 Gbps, including
computer and video resolutions up to 4096x2160 @ 30 Hz and 1080p @ 60 Hz with Deep
Color, 3D, Lip Sync, and HD lossless audio formats.
NOTE:
All three models feature EDID Minder, which maintains continuous EDID communication
between connected devices, and Key Minder, which continuously authenticates HDCP
encryption between all devices, ensuring the simultaneous distribution of source content to all
displays.
The DA HD 4K Series provides automatic input cable equalization (up to 25 feet, 7.62 meters,
for 4K signals), automatic color bit depth adjustment, and allows outputs to be independently
muted.
Front panel LEDs provide immediate confirmation of HDCP authentication and signal presence.

Application Diagram
Extron strongly recommends compatibility testing while designing, and before installing
any 3D system. There are several unique 3D formats in use by source devices and display
manufacturers. The level of 3D product support is governed by pixel clock, signal format, and
communication between source and sink devices. Please contact an
Engineer
for more information.
