Output Compatibility Correction — monitoring the EDID of each connected display allows
the distribution amplifier to ensure the EDID is compatible with the current input signal. The
following adjustments are made for each output independently:
•
•
Output muting via RS-232 — Provides the capability to mute one or all outputs at any
time. This allows content to be viewed on a local monitor prior to appearing on the main
presentation display.
Signal Status LEDs for the input and each output — provide real-time feedback and
monitoring of signal presence and HDCP authentication. The bi-color EDID LED indicator
notifies whether an internal or external EDID is stored.
Easy setup and commissioning — using the Extron PCS (Product Configuration Software),
which allows multiple products to be configured using a single software application.
Easy mounting options — The HDMI DA2 is a quarter rack wide, 1 inch high, and 3 inches
deep. The HDMI DA4 and HDMI DA6 are a half rack wide, 1 U high, and 6 inches deep. All
three models can be conveniently mounted in standard racks or under furniture.

Interface format: If the connected display is DVI and the input signal is HDMI, the signal
is reformatted to DVI. If the output is HDMI and the input is DVI, no reformatting is needed
because HDMI is backwards compatible with DVI.
Video color bit depth: If the connected output device does not support the color
bit depth of the input signal, it is truncated down to the next level that is supported
(12-bit > 10-bit > 8-bit). The signal can be forced to always truncate to 8-bit via Simple
Instruction Set (SIS) commands, disabling deep color.
