NOTE: Secure the input and output connectors to the distribution amplifier with the
provided LockIt HDMI lacing bracket (see

By default, the EDID is set to 720p @ 60 Hz with 2-channel audio. However, EDID can be
changed by using SIS commands (see the

In addition to 12 factory-loaded EDIDs, there are six slots that are automatically populated
by EDID from connected sink devices and two slots that can be manually populated by
the user. For more information, see the
The distribution amplifier monitors 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:
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 SIS
commands, disabling deep color.
Audio — If the connected output device does not support the audio format of the
•
input signal, audio is muted.
If the source requires HDCP encryption and the display is not HDCP compliant, that
output channel outputs a green screen.
Both outputs carry +5 VDC and up to 250 mA on pin 18, regulated by a current limiting
circuit.
