About the HDMI DA2
The Extron HDMIDA2 distribution amplifier distributes one HDMIinput signal to two
outputs simultaneously. It is fully High‑bandwidth Digital Content Protection (HDCP)
compliant.
The HDMI DA2 supports data rates up to 6.75 Gbps (2.25 Gbps per color) with up to
12‑bit deep color and uses the EDID Minder feature for EDID management.
The automatic output compatibility correction feature scans each output device to ensure
that the output signal is compatible with the audio capabilities, color depth, and format
requirements of the device. Each output is adjusted independently.
HDMI DA2 Features
HDMI signal distribution — The HDMI DA2 accepts one HDMI input and provides two
HDMIoutputs.
Key Minder — Key Minder authenticates and maintains continuous HDCP encryption
between the input and output devices to enable simultaneous distribution of a single
encrypted source to two displays.
Signal Status LEDs — Front panel signal status LEDs indicate TMDS and HDCP status
for the input and each output.
EDID Minder — This feature allows the user to choose from a list of 46factory‑loaded
EDID files, to import EDID information from either of the display devices, or to import
and save an EDID file from a PC. EDID Minder has two modes of operation that can be
selected and configured using SIS commands:
z Automatic: EDID from the display connected to output 1 is read and stored at the
input automatically (default mode). Use SIS commands to read and store EDID from
output 2.
z User assigned: EDID can be manually assigned from the internal factory EDID
table, which contains 46 unique EDID files categorized by native resolution and audio
support. Additionally, there are four user slots available to store and recall EDID from
connected displays.
