INTRODUCTION

The Gefen 8x4 Matrix for HDMI

The rack-mountable 8x4 Matrix for HDMI sends high defi nition video and
multichannel digital audio from any of 8 HDMI sources to any 4 Displays. The
HDMI inputs consist of 4 High Defi nition video switches that can each accept 2
video sources. This input scheme allows up to 8 sources to be available while
viewing any 4 on the output displays concurrently.

The 8x4 Matrix for HDMI eliminates the need to disconnect and reconnect
sources to displays. It works with Blu-Ray players, Set-Top boxes, Home
Theater PCs, and game consoles that connect to an HDMI display. Any source
is accessible at all times by any display by selecting it using an IR remote or an
RS-232 remote control device. The Matrix comes with rack ears for mounting in a
shelving system.

How It Works

Up to 8 HDMI sources (4 viewable at any one time) connect to the Matrix’s inputs
and up to four Displays connect to the Matrix’s outputs. Power up the 8x4 Matrix,
HDMI sources and all connected Displays. Select which HDMI sources you want
to view on each display using the IR remote. The result will be clear and vibrant
HDMI video with multichannel digital audio at each Display.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 8X4 MATRIX FOR HDMI

• Important Note: The 8x4 Matrix for HDMI incorporates a 2x1 switch in front

of each input on a traditional 4x4 matrix. This allows for the connection of up
to 8 different HDMI source devices with a maximum of 4 sources available
for viewable at any one time. Each of the 4 switched inputs on the 8x4 Matrix
for HDMI are labeled as “A” and “B”. Both “A” and “B” for each input cannot
be active at the same time.

Example A (Multiple outputs viewing the same input source)
Devices: 1A (DVD player) & 1B (Cable STB)
Scenario: Outputs 1 and 2 are both viewing input 1A (DVD).
Action: User viewing output 1 switches the input from 1A (DVD) to 1B

(STB).

Result: Both outputs 1 and 2 will be switched to viewing 1B (STB).
Example B (Multiple outputs viewing separate input sources)

Devices: 1A (DVD player), 1B (Cable STB), and 2A (Video Game system)
Scenario: Output 1 is viewing 1A and output 2 is viewing 2A.
Action: User viewing output 1 switches the input from 1A (DVD) to 1B

(STB).
Result: Output 2 is not affected by the change of 1A to 1B because it is

viewing a source (2A) on a different input.

• Display information (EDID) from the displays attached to the 8x4 Matrix for
HDMI need to be sent back to the input sources. Please see page 10 for
EDID management features and options.

• HDMI 1.2 compliant (HDMI 1.3 compatible)

• HDCP compliant
