Intr oduction This guide describes the function, installation, and operation of the Extron HDMIDA2 distribution amplifier . Unless otherwise stated, the terms “distribution amplifier” or “DA” refer to the HDMI DA2.
Output Compatibility Correction — The HDMI DA2 monitors the EDID of each connected display to ensure it is compatible with the curr ent input signal. The following adjustments are made for each output independently: z Interface format: If the connected display is DVI and the input signal is HDMI, the signal is reformatted to DVI.
Installation This section of the guide describes the following topics concerned with the installation and setup of the HDMI DA2 distribution amplifier .
Connecting the Power Supply Connect the provided 12 VDC, 1 A power supply to the HDMI DA2 by following these instructions: W ARNING: Remove power before wiring.
Connecting the Input Sour ce Use an HDMI cable to connect the input source to the female HDMI socket on the r ear panel ( b in figure 2 on page 3). The connectors are fully HDCP compliant. With cables up to 25 feet (7.6 m) they support resolutions of up to 1080p @ 60 Hz with 12‑bit color .
If the source r equires HDCP encryption and the display is not HDCP compliant, that output channel outputs a green scr een. Both outputs carry +5 VDC and up to 250 mA on pin 18, regulated by a curr ent limiting circuit.
Connecting to the USB Port The mini T ype B USB port is located on the HDMI DA2 front panel ( b in figur e 7 on page 10). It can be used to connect the distribution amplifier to a host computer to update firmware or for configuration using SIS commands.

Output Signal LEDs There ar e two output signal LEDs, one for output 1 and the other for output 2.
EDID Minder EDID Minder ensures that the connected sour ce sees the EDID of a display , even if a display is not connected. Depending on the EDID mode selected (by SIS command), the EDID of a connected display can be stored automatically , or the user can manually select from the table of factory loaded EDID files.
