How it works !
The main task for a digital matrix is the reliable and fast switching of sources. A complete seamless switch
for DVI or HDMI signals is virtually impossible. Only a PIP processor can blend or switch seamlessly which
requires scaling engines and buffers. They introduce new problems like unwanted delays and scaling
artefacts hence we have not implemented them. There is also a substantial higher cost factor and setup of a
scaling matrix requires time and expertise.
We have tried to make the fastest switching “traditional” matrix using our unique SingleEDID technology
and HDCP key buffering and repeater ICs for input and output. We do not touch the signal so no artefacts !
With HDCP encrypted HDMI signals and fast displays you may achieve less than 2s switching time.
We have achieved instant switching for DVI signals with professional monitors if there is no change in
resolution.
If you want fastest possible switching the display is the one that makes the difference. They typically
monitor all incoming signals on their input and resync if there is a change in resolution, a glitch in the signal
transmission or Hotplug signalling. We have seen anything from 1s to 10s with our matrix, so quite a
difference.
An important feature is the EDID management that allows access to all parameters of the EDID information
Our implementation allows free assembly of the EDID information for each input. Full control !
Additionally we offer two 3D EDID, a 720p default EDID and the ability to learn EDID from any output of the
matrix.
We are using HDMI 1.3 compatible repeater ICs that are working with any HDMI and DVI signal. All 3D
signals are compatible with the unit, the ability to learn EDID makes the matrix future proof with upcoming
3D formats. Each input card offers 2 inputs and 2 monitor outputs that may be used for local monitoring or
expansion with a second matrix to create a 16x32 array or even 16x64 (requires 4 matrices).
Each output card has 2 HDMI and 2 Dual Cat5 outputs that are both active. A fully loaded matrix is
therefore offering 16 logical but 32 physical outputs.

Operate it
IR Remote control
Like any infrared controlled device the
MATRIX-X1616
has limitations for distance and angle. Typically
you will need a direct line of sight. The remote control uses standard commands and carrier frequencies so
there should be no problem to learn the commands. You may download Crestron and RTI files from our
website.
In general it is adviced to avoid infrared control for a matrix and use RS-232,Telnet or the webinterface.
There is one convenient feature using our 2XCAT5IR-RX units with the Dual Cat5 ouputs. Each 2XCAT5IR-
RX has a connection for a SPATZ IR-RX infrared receiver that can receive IR commands from the SPATZ
remote or remotes from BD player or settop boxes.
With the SPATZ remote you can control the matrix from each output (Zone) and switch inputs.
It is necessary to wire a SPATZ IR-DoubleTX from IR OUT 1 (upper connection of input card 1) and
stick it to the IR window at the front of the unit. Remote control of settop boxes or other sources is done in
a way that only outputs that are actually connected to inputs are sending IR commands to the input cards.
e.g. output 2 is connected with input 1 and output 4 is connected with input 3. The matrix will forward IR
signals from ouput card 1 and 2 (outs 2 and 4) to input cards 1 and 2 (inputs 1 and 3). The other input
cards are not receiving these IR signals.
This intelligent IR routing allows to use same make settop boxes on different zones.
