Installation and Operation

Before permanently securing the unit for final installation of cabling behind walls or ceilings, test
for proper operation of the unit and the cables in your system. It is recommended that you leave
enough ventilation space to provide sufficient airflow and cooling, especially if you are going to
leave the unit powered at all times.
Active Input / Output LED Indicators
The front LED indicators indicate that a valid HDMI / DVI-D
½
connection is made between the KD-HDDA unit and each
Input / Output.

EDID Control Settings

At times, your HDMI sources and display may not synchronize properly. This is
when EDID* control should be utilized. KD-HDDA Distribution Amps feature an
internal library of default settings that ensure that your HDMI source's output is
compatible with the display devices.

Dip Switch Configurations:
Configuration Description
000 Auto selection of highest common EDID of output devices
001 EDID copied from first connected output regardless of output number (1-8)
010 Video = 1080i, Audio = L/R Stereo
011 Video = 1080i, Audio = All Audio formats including HDMI 1.3a/b
100 Video = 3D 1080p, Audio = L/R Stereo
Display 1
101 Video = 3D 1080p, Audio = All Audio formats including HDMI 1.3a/b
110 Video = 1080p Audio =L/R Stereo
Display 2
111 Video = 1080p Audio = All Audio formats including HDMI 1.3a/b
All Others Highest common EDID of output devices
Display 3
Example of EDID Auto Select:
Display 4
If one of your system's displays supports 1080p, however the second display only supports up to
1080i (does not support 1080p), then the highest common EDID format supported is 1080i. By
choosing the Auto Select EDID Setting, your KD-HDDA unit will inform your source device to output
1080i in order to ensure that all displays receive a supported signal.
* EDID (Extended display identification data) is a data structure provided by a display to describe its capabilities to a
source device.
NOTE: the DIP settings are 0 = down / off and 1 = up / on.
= 101
Please reset the unit by either unplugging and plugging the
HDMI connections, or via a power cycle for the new settings
to take effect.
