About the HDMI DA2

The Extron HDMI DA2 distribution amplifier distributes one HDMI input 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 HDMI outputs.

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 46 factory‑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:

zz 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.

zz 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.
