About the DA2 HD 8K L
The Extron DA2 HD 8K L is a one input, two output HDMI distribution amplifiers for 8K signals. It distributes one
8K input signal to two simultaneous outputs. The DA2 supports data rates up to 40 Gbps, including computer and
video resolutions up to 7680x4320 @ 30 Hz 8‑bit 4:4:4 and 7680x4320 60 Hz 8 bit 4:2:0 with Deep Color, 3D,
Lip Sync, HDR (high dynamic range), and HD lossless audio formats.
NOTE: Extron strongly recommends compatibility testing while designing, and before installing any 3D
or HDR system. There are several unique 3D and HDR formats in use by source devices and display
manufacturers. The level of 3D and HDR product support is governed by pixel clock, signal format, and
communication between source and sink devices. Please contact an
page 42) for more information.
The DA2 HD 8K L features 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 DA2 HD 8K L distribution amplifier provides automatic input cable equalization up to 15 feet (4 meters) for
8K @ 60 Hz 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.
Features
•
8K signal distribution — Distributes 8K HDMI video and embedded multi‑channel digital audio signals. This
distribution amplifier accepts one 8K input through a female HDMI type‑A connector and provides two
simultaneous outputs.
•
Supports HDMI 2.1 specifications, including:
•
Data rates up to 40 Gbps
•
Deep Color up to 12‑bit
•
3D
•
Lip Sync
•
HDR
•
HD lossless audio formats
•
Supports computer and video resolutions up to 8K, including 1080p @ 60 Hz Deep Color.
•
EDID Minder — Automatically manages EDID communication between connected devices ensuring that the
source powers up properly and reliably outputs content for display.
•
HDCP compliant — Ensures display of content‑protected media and interoperability with other
HDCP‑compliant devices. Supports HDCP 2.3 and compatible with non‑HDCP 2.3 sources and sinks.
•
Key Minder continuously verifies HDCP compliance — Key Minder authenticates and maintains
continuous HDCP encryption between all input and output devices to enable simultaneous distribution of a
single source signal to two, four, or six displays.
