Four Component Sources
to Four Displays. Independently.
Connect and Access Any Four (4)
Hi Def. Sources to Any Four Hi Def. Displays
The 4x4 COMPONENT Matrix routes high definition
video in multiple resolutions up to 1080p plus stereo
audio from any of the four Component /Audio sources to
four displays. Any four Component / Audio sources to any
four displays using matrix switching allows for maximum
versatility for integrated systems. The 4x4 Component /
Audio matrix eliminates the need to disconnect and
reconnect sources or displays. It works with DVD players,
DVR systems, HT PCs, and satellite set top boxes that
connect via component to displays. Every source is
accessible at all times by any display by routing it using
an IR remote or RS232 smart control devices.
How It Works
You simply connect the four component and audio sources
to the Matrix's inputs. Then connect four displays to the
Matrix's outputs. Once the sources, the matrix and the
displays are powered and connected, you simply select
which sources you want view on which displays using the
IR remote or RS232 smart control devices.
Note: This Component/Audio product supports BOTH
Audio and Video signals, If used in conjunction with the
EXT-COMPAUD-141 it will extend component video and
audio up to 1000 feet (300 meters) using one CAT-5e
cable

INTRODUCTION
Thank you for purchasing the 4x4 Component Audio Matrix.
The 4x4 Component Audio Matrix switches four component video with analog audio
sources to any four component with analog audio displays.
The 4x4 Component Audio Matrix switcher has four component video with analog audio
inputs and four component with analog audio outputs. There are 4 component video
( 3 RCA) with analog audio ( 2 RCA) inputs and 4 component ( 3 RCA) with analog
audio ( 2 RCA) outputs.
Note: The switching is done by using either the RMT-16-IR remote control or through
the RS232 port. The 4x4 Component Audio Matrix is rack mountable.

RMT16-IR INSTALLATION
1. Remove battery cover from the back of the RMT16-IR remote.
2. Verify that dip switches 1 & 2 are in the down (OFF) position.
3. Insert the battery, hold the battery so that you can see the positive side facing up.
The side that is not marked must be facing down.
4. Test the RMT16-IR remote by pressing ONLY one button at a time. The indicator
light on the remote will fl ash once each time you press a button. WARNING: Do not
press multiple buttons simultaneously and do NOT press buttons rapidly. These actions will cause the remote to reset and steps 1-4 will have to be repeated.
Note: The RMT16-IR ships with two batteries. One battery is required for operation,
the second battery is complimentary.

DDC
Short form for Display Data Channel. It is a VESA standard for communication between a monitor
and a video adapter. Using DDC, a monitor can inform the video card about its properties,
such as maximum resolution and color depth. The video card can then use this information to
ensure that the user is presented with valid options for confi guring the display.
DDWG
Digital Display Working Group DDWG are the creators of the DVI specifi cation.
DVI
Digital Visual Interface. Connection standard developed by Intel for connecting computers to
digital monitors such as fl at panels and DLP projectors. A consumer electronics version, not
necessarily compatible with the PC version, is used as a connection standard for HDTV tuners
and displays. Transmits an uncompressed digital signal to the display. The latter version uses
HDCP copy protection to prevent unauthorized copying.
HDCP
High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals
over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized
duplication of copy written material.
HDMI
The High-Defi nition Multi-media Interface (HDMI) is an industry-supported, uncompressed,
all-digital audio/video interface. HDMI provides an interface between any compatible digital
audio/video source, such as a set-top box, DVD player, and A/V receiver and a compatible
digital audio and/or video monitor, such as a digital television (DTV).
HDTV
High-Defi nition Television. The high-resolution subset of our DTV system. The ATSC defi nes
HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system,
accompanied by 5.1 channels of Dolby Digital audio. The CEA defi nes HDTV as an image
with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and
1920:1080i are typically accepted as high-defi nition scan rates.
RS-232
Recommended Standard 232. This is the de facto standard for communication through PC
serial ports. It can refer to cables and ports that support the RS232 standard.
VESA
Video Electronic Standards Association, a consortium of manufacturers formed to establish
and maintain industry wide standards for video cards and monitors. VESA was instrumental in
the introduction of the Super VGA and Extended VGA video graphics standards with a refresh
rate of 70 Hz, minimizing fl icker and helping to reduce user eyestrain and fatigue.
