MATRIX ROUTING SWITCHER
1 HARDWARE
1.1 GENERALITIES
The Kramer matrix switchers are used to select and
dispatch electric signals, as audio, video and RGB,
to several destination simultaneously. The
impedances of each machine which is connected on
the matrix are well respected, even if a signal goes
to two outputs and more. As a matter of fact, a
signal under 75 Ohms can’t be delivered on several
loads without any amplification dispositive.
In fact, each output is able to select one, and only
one, input. We can consider the matrix routing
switcher as an assembly of several selectors which
are adjacent and connected on common inputs.
Each selector is fully independent, and individually
controlled. When two selectors, or more, request
the same source, this last is then distributed. So, it
have to be buffered to avoid losses of electric level
and reduce of bandwidth. The number of selectors
depends of the power and the quality of the buffers.
The control of the switching and the others
commands is provided by an interface RS232/422,
via an internal bus.
The routing switcher don’t make use of a keyboard
in front panel. The access of this keyboard should
not be easy, or impossible, when the matrix is at the
heart of the audio and video lines, to have the
shortest length.
A supervisor, a computer or a remote control panel
must necessarily control the matrix by the RS232
and RS422 connectors.
Several LED lights on the front panel shows the
receipt of the RS232/422 datas, the kind and the
result of the actions.
An electric power supply provides four various
tensions the cards of the machine.
1.2 RACK DISPOSITION
The cards are housed in a 19 inches rack, with 360
mm depth, and a height which is multiple of 3RU,
according to the number and the dimensions of
each section.
Many section, as audio, video, RGB, YC, or YUV,
can be inserted in the same rack.
The cards are introduced by the rear panel and
support the audio and video plugs.
These are BNC for composite video, components,
YC and RGB. For the audio, (balanced or
unbalanced), the plugs are terminal blocks 6 points
detachable.

1.3 CREATING A MATRIX
The rear panel of the rack is 19” wide, on 3RU
high. The mains, RS232 and RS422 plugs 1RU,
and the useful area for the audio, video et RGB is
also 1RU. The BNC or audio connectors are shared
by 32, on horizontal bands which are 1RU wide.
We can house up to 3 bands in a 3RU area, i.e. 96
BNC or audio plugs. So, we can realize a 32x64
video matrix, or a 64x32…
When more, the rack has to be 6RU high. Then the
total number of plugs rise to 192, and permits
important dimensions. With a 9 RU rack, the
number is 288, etc.
The stereo audio plugs are also shared by 32, on
1RU band. We can house 3 bands, i.e. 96 stereo
audio plugs. For example, in a 3RU unit, we can
realize a stereo balanced 32x64 or 64x32, more in a
6RU, etc.
In YC mode, the capacity the divided by two ; in
component mode, by three ; in RGBHV mode, by
five.
1.5 RGBHV SECTION
RGBhv architecture is the same as the video
section :
Each card can support the R, G, B, H or V, and is
simultaneously controlled.
The input and output impedances is a 75 Ohms on
BNC, and the bandwidth is 350 MHz minimum.
1.6 AUDIO SECTION
The architecture of the audio path is different.
1.4 VIDEO SECTION
The video section in an area with cards including
the input and outputs plugs, the buffers, the
switchers, the outputs 75 Ohms amplifiers, and the
controllers. The input cards (called QMI), and the
output cards (called QMO), own four edge
connectors to get the power supply and the service
signals by the internal rail.
Each cards has 32 BNC connectors for in or out.
There is no module as for the video, but traditional
cards, directly connected on the internal bus. On
this bus transit the stereo audio signals, and also the
power distribution and the service signals.

MATRIX ROUTING SWITCHER
The cards are horizontally located, and can be
extracted by the front panel. Each card own up to
32 stereo plugs. There is two types of audio cards :
- Input audio cards.
Called WMI, these cards are identical between
themselves. The only differences are the serigraphy
of the panel and its position in the slots.
When viewing from the rear panel, these cards are
immediately slotted near the QMOSD card
(communication card). Their 32 audio plugs can be
set up in factory, as balanced or unbalanced, or
mixed.
Balanced mode has a +4dB level under 6 KOhms
impedance., and the unbalanced mode, -6dB under
10 KOhms. Dynamic is 12 dB. The inputs are
directly introduced into the integrated circuits, and
have no galvanic isolation.
- Output audio cards.
Called WMO, these cards are physically identical
between themselves, but have to be programmed
for identification. Their position is immediately
near the input cards. Their 32 audio plugs have no
galvanic isolation. The output impedance is 50
Ohms. We can use the output in balanced mode, as
in unbalanced only without connecting the inverted
pin. (Do not connect this pin to the ground).
Up to 32 VCA (Voltage Control Amplifiers) can be
wired in factory. So the audio level can be adjusted
with a special RS 232 command.
1.7 OTHERS SECTIONS
YC (S-video), component YUV, and RGsB can be
realized with the analogue video cards, with the
same principle as RGBhv section.
1.8 COMMUNICATION
The card called QMOSD is the heart of the
KRAMER matrix routing switcher. This card own
a clock generator, a microcontroller, and provides
the service signal to the others cards of the
machine. The reception and the treatment of the
RS232, RS422 and Ethernet is made inside and the
datas are then transferred the concerned switchers.
As there is no keyboard on the front panel of the
matrix, the QMOSD card take on the dialog with
the external keyboard by the RS422 link.
1.9 ON SCREEN DISPLAY
The GMOSD card has a SVGA 800x600 generator
that is available on a SubD-HD15 connector. An
external screen can be connected on, and propose a
listing of the matrix status.
On the left is shown the list of 80 input sources, as
13 characters names.
On the right area are shown 80 outputs name, with
the status of switch.
A mouse can be connected on a USB-A connector,
to control the upper tool bar, and to create switches.
The loading of this table is automatically done with
the MatrixOp4 software, after entering the
assignment operation.
1.10 INTERVAL SWITCHING
Switching during the black interval is basic to get a
clean change of picture, without break of the
synchronization, and cut in the middle of the
screens. When the reference signal is present
(blackburst), the switching takes place in the
beginning of the video frame, that is to say in the
middle of the line N°2 or 314 in PAL/SECAM
(N°2 or 264 in NTSC). The maximum waiting time
is of 20 mS in PAL and 16,7 mS in NTSC. This
operation can be effective only when the sources
are synchronized with the blackburst. If this
condition is not perform, then the switch is made
normally out of the interval time.
