ASSEMBLY
User Interface
Assembly of the new MisMatcher01 REV.D has been greatly simplied compared
to previous versions. With most of its critical components already soldered in place,
users only have to solder a handful of jacks and potentiometers, reducing human
error during assembly.

6
Start by snapping the three potentiometers in place, followed by the three gold
RCA jacks and lastly the seventeen PJ-341 jacks.
Secure the PCB and solder these components. Keep in mind that some
components might move when you ip the PCB upside down or while soldering. To
avoid this, press the components against the PCB as the solder ows to ensure their
most upright position.
Finish off by performing a visual inspection on the solder joints.
The 8-pin male header will be assembled later.

7
Main PCB
Start by snapping the three potentiometers in place as well as the piano DIP
switch. To ensure the correct placement of the power switch and the male and female
header, place these components and then secure the two PCBs with the 8 screws
and four standoffs provided.
Solder these components and nish off with a visual inspection of the solder
joints.

PRINCIPLE OF OPERATION
An electronic analog video glitcher
is a device designed to distort analog
video signals using analog circuitry.
The MisMatcher 01 works with
composite video, the yellow RCA jack
fromcamerasandmonitors,and contains
three different analog circuits, Sync
Separator, Sync Mixer and Enhancer.
Feedback and gain controls are available
for the Enhancer. These circuits can be
used individually or interconnected
between each other.
To connect cameras and monitors
totheMisMatcher01youjust need amale-
to-male RCA cable. These are connected
through the gold RCA jacks in the front
of the unit and from there on you’ll only
need to use patch cables to interconnect
the previously mentioned circuits.
The MisMatcher 01, like a guitar pedal, is used inline in between the source of
the signal and its destination. A quick example would be a camera connected to the
Enhancer In and the Enhancer Out connected to a monitor. To power the MisMatcher
01, you’ll only need a USB charger and Micro USB cable. If you see horizontal lines in
the screen, this is due to a noisy USB charger. Replacing the charger will resolve the
issue.

BASICS OF ANALOG VIDEO SIGNALS
An electronic analog video glitcher is a A composite video signal, or CVBS, is
comprised of colour or chroma, video or luma, blanking and sync information in only
one channel. CRT monitors draw images using a process called raster scan, where the
image is drawn line by line, from top to bottom, left to right. Looking at a video signal
through the help of an oscilloscope we can determine some of its components. Each
line starts with the horizontal 9 syncing pulse which lets the monitor know it’s time to
draw a new line. After that we have the colour burst, which gives the base reference
for the colours to be drawn. Next, we have the picture information which contains the
luma, brightens information and chroma, HUE and saturation. A new line is drawn
once the monitor receives another horizontal sync pulse. This process is repeated
across the whole monitor multiple times a second to create the illusion of moving
images. The example given would display 5 horizontal grey bars with increasing
brightness if feed onto a CRT Monitor.

FEATURES
Passive Mixers / Attenuators
Sync Separator And Sync Mixer
The three potentiometers in the user interface can be used to either attenuate
the intensity of a video signal, or to fade between two different video signals. The
potentiometer’s jacks are automatically connected to ground if no patch cable is
inserted. Thanks to this you can easily create an attenuator by connecting your video
source to one of the potentiometer’s xed ends and leaving the other xed end
unplugged. The attenuated signal can be accessed through the wiper jack in the
middle of the potentiometer. To fade between two video sources, simply connect one
source to one xed end of the potentiometer and the other video source to the other
xed end. The wiper will give you the mix between the two.
The key to a stable picture is a good sync signal. The distortion of video signals
can deteriorate sync, leading to horizontal or vertical scrolling of video on screen.
When the loss of sync is undesired by the user, the Sync Separator and Sync Mixer can
come into play. The Sync Separator extracts the sync portion of the video signal. The
Sync Mixer then takes the video signal connected at the Sync Mixer In and remixes it
with the sync provided by the Sync Separator, resulting in a stable image. Instead of
restoring the sync of a video signal, the user can also remix one video source with the
sync signal from another video source, resulting in a scrolling image with constructive
and destructive interference.

Enhancer
This enhancer can be used to either boost saturation and sharpness of the
video or, using the provided Gain and Feedback 1 and 2 controls, to distort the video
and create interesting effects. The gain controls how much the signal is amplied.
Feedback 1 and 2 takes video from different stages of the circuit and feeds it back into
the Enhancer’s input.

PATCHING EXAMPLES
In this rst example connect camera A to RCA A and monitor A to RCA C. Then
patch camera A to Enhancer In and monitor A to Enhancer Out. Control the enhancer
trough its gain, feedback 1 and 2 knobs, as well as the DIP switch.

You may nd that, if you push the Enhancer too hard, you may lose sync on your
monitor. To solve this, rst split camera A into Sync In and Enhancer In. Then patch
the Enhancer Out into the Sync Mixer In and nally Sync Mixer Out to monitor A.
This way you restore your video’s sync after the Enhancer, with the help of the
Sync Mixer, using the video signal provided on the Sync In as reference.

You can take it one step further and use the Sync Mixer as a glitcher.
Split camera A into one of the pot’s xed end and into another pot’s xed end.
Patch the rst pot’s wiper to the Sync In. Patch the second pot’s wiper to the
Enhancer In. Patch the Enhancer Out onto the third pot’s xed end. Patch the third
pot’s wiper to the Sync Mixer In and nally the Sync Mixer Out to monitor C.
The rst pot creates a sort of luma keying effect. The other two act as attenuators.
Start with them on full counter clock wise and go from there.
You can also use the Sync Mixer’s low pass lter to create a ghostly effect.

You don’t have to limit your workow to only one camera. In this example we’ll
create a more advanced Karl Klomp style video mixer.
Connect camera A to RCA A, camera B to RCA B and monitor A to RCA C. Split
camera A onto the rst pot’s xed end and the third pot’s xed end. Split camera B
onto the rst pot’s other xed end and the third pot’s other xed end.
Patch the rst pot’s wiper into Sync Mixer In. Patch the third pot’s wiper into
Sync In. Patch Sync Mixer out to monitor C.
The rst pot act as a dirty fader between camera A and B. The third pot fades
between camera’s A and B sync. This sync signal is what the nal result will be synced
to.
