MisMatcher01
About
The MisMatcher01 is an analog video effects unit comprised of a sync mixer
and an amplifier. It’s intended to work in tandem with another control board
trough a connection header. The sync mixer extracts the sync pulses from a
video signal and mixes them with another video signal. It’s used to restore the
sync timing after modifying a video signal or to re-sync a video signal with
another video. The amplifier clips the video signal with a variable threshold
limit, providing a monochromatic black and white signal.

PatchModule01
About
The PatchModule01 is a 3.5 mm patch cable control module for the
MisMatcher01. It works as the user interface, providing input and output RCA
jacks, 3 mixers and an easy way to combine different video signals with the
different functions of the MisMatcher01. The 3.5 mm stackable patch cables
are needed but not included.

Assembly
Start by soldering the red 8-pin female header.
Solder the two 220
F 
electrolytic capacitors, the 270

resistor and LED.
Solder the remaining components. If you have any trouble fitting the RCA
jacks and potentiometers to the PCB, please use a plier to straighten out the
component’s leads. Beware that two of the 3.5 mm jacks have had a specific
pin removed in order to fit in the PCB.
Clean the flux residue left behind. Finish off by soldering the two 12 mm spring
loaded SMD pin on the back. Make sure they are centred on the pad and
that they make contact with the resistor underneath on the MisMatcher01
board when assembled.

Patching Examples
Cross Dissolve
Video Input: A and B
Video Output: C
Connect source A to the fixed end of potentiometer A. Connect source B to
the other fixed end of the same potentiometer. Connect the potentiometer
wiper to the output C. Rotate the potentiometer and the video output will
cross fade between A and B, loosing sync in between.
Attenuator
Video Input: A
Video Output: C
Connect the source A to the fixed end of potentiometer A. Connect the
other fixed end to the ground jack. Connect the potentiometer wiper to C.
This will create a voltage divider, reducing the signal intensity, loosing detail,
colour and sync in the process.
