The Gefen 8x8 Crosspoint Matrix for HDMI 1.3
The Gefen 8x8 Crosspoint Matrix for HDMI 1.3 routes high definition video at
resolutions of up to 1080p with multichannel digital audio from any eight HDMI
sources to any eight displays. The 8x8 Crosspoint Matrix supports advanced
digital audio formats such as Dolby True HD and DTS-HD Master audio. Each
source is accessible at all times by any display by selecting it with the included
IR remote, by using the RS-232 port or by using the button switches on the front
panel.
How It Works
Connect up to eight Hi Def sources to the Gefen 8x8 Crosspoint Matrix for HDMI
1.3 using the supplied HDMI cables. Connect up to eight HDTV displays to the
Matrix’s HDMI outputs. 3D content can be displayed when connecting a 3DTV
and 3D source. Power-on the Matrix and apply power to the sources and to the
displays. A/V sources can now be routed to any combination of display devices
using the front panel buttons, the included IR remote control or RS-232 control.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE GEFEN 8X8 CROSSPOINT MATRIX FOR HDMI 1.3
• There is no internal scaling in the Gefen 8x8 Crosspoint Matrix for HDMI 1.3.
All of the attached monitors must be able to display the resolutions output by
the source devices. For maximum compatibility it is recommended that only
one compatible / common resolution be used by all of the source devices.
• The Gefen 8x8 Crosspoint Matrix for HDMI 1.3 is a full-featured crosspoint
matrix for eight inputs and eight outputs. Any source can be connected to
any display at any time, using the remote control or by controlling it via the
buttons on the front panel.
• 3D content pass-through is enabled to all outputs when a 3DTV is connected
to Output A. Ensure to power cycle the Matrix once a 3DTV is connected to
Output A during standard operation.

How to Resolve IR Code Conflicts
In the event that IR commands from other remote controls interfere with the
supplied IR remote, changing the remote IR channel will fix the problem. The
IR remote control has a bank of DIP switches used for setting the remote IR
channel.
The DIP switch bank on the IR remote is located underneath the battery cover.

compartment of the IR remote showing the
exposed DIP Switch bank between the battery
chambers.
It is important that the remote IR channel selected on the remote, matches the
IR channel set on the Gefen 8x8 Crosspoint Matrix for HDMI 1.3. For example,
if both DIP switches on the IR remote are set to IR channel 0 (toward the “1” and
“2”), the Gefen 8x8 Crosspoint Matrix for HDMI 1.3 must be set to use IR channel
0.
See page 12 on how to change the IR channel on the Gefen 8x8 Crosspoint
Matrix for HDMI 1.3.
IR REMOTE CONFIGURATION

The IR remote control will allow the user to select which source will be routed to
which output. Each of the two (2) outputs are assigned a group of four buttons
which correspond to the four source inputs. Please use the information below
when selecting the desired source for each display.

Use the Input + and Input - buttons to switch between OFF and ON states. Use
the table below to set the correct IR channel.
It is important that the IR setting that is selected match the DIP switch settings
on the IR remote. For example, if both DIP switches on the IR remote are set
to the down position (channel 0), the IR channel for the Matrix must be set to IR
channel 0 (“IR Address : 0, 1-OFF, 2-OFF”).
