Automatic input cable equalization — to 50 feet at 1080p/60 with 8‑bit color when used
with Extron HDMI Pro Series cable. Actively conditions incoming HDMI signals to compensate
for signal loss when using long cables, low quality cables, or source devices with poor signal
output.
Output Compatibility Correction — The distribution amplifiers monitor the EDID of each
connected display to ensure it is compatible with the current 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. If the output is HDMI and the input is DVI, no reformatting is needed
because HDMI is backwards compatible with DVI.
z
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.
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 — LED indicators for signal presence
and HDCP authentication provide real‑time feedback and monitoring of key performance
parameters. The bi‑color EDID LED indicator notifies whether an internal or external EDID is
stored.
Easy mounting options — The HDMI DA4 and HDMI DA6 are a half rack wide, 1 U high, and
6 inches deep. They can be conveniently mounted in standard racks or under furniture.
