Page 4: Basic Mismatcher 01 Rev.b Features
Video inputs, such as cameras or VCRs, and outputs, such as monitor or ADCs, can be connected to the MisMatcher01 trough three RCA jacks. The user interface provides users with various patch point, enabling them to interconnect different parts of the circuit together for a vast array of effects. -

B. USER INTERFACE Start by placing the PJ-341 jacks and solder them. Snap the gold RCA jacks and potentiometers in place. Place the LED in the right orientation as well as the 270 current limiting resistor. Solder these remaining components. The male header will be soldered later on. To passively mix two video signals with one potentiometer, solder a 500 resistor from one fixed end of potentiometer A to the wiper, and... - Page 7 Snap the three potentiometers in place along with the DIP switch and jumpers. Solder them. Place the LM1881’s socket in place. When soldering, jump pin 2 and 3 together with solder. Trim pin 3 off the LM1881. Install the LM1881 only after soldering the socket.

IV. BOOTING UP With the 2 PCBs mounted together, connect a Micro USB charger to the Micro USB port and turn the switch on. The LED should light up. Connect a video source to jack A and a monitor do jack C. Patch these 2 points together and you should see the source on the monitor. -
Page 9: Sync Separator And Sync Mixer
VI. SYNC SEPARATOR AND SYNC MIXER The key to a stable picture is a good sync signal. The mixing, attenuation and distortion of video signals can deteriorate sync, leading to horizontal or vertical scrolling of video on screen. When the lost of sync is undesired by the user, the sync separator and sync mixer can come into play. -
Page 10: Enhancer
VIDEO BURST Composite Video Composite Sync VII. ENHANCER This video 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 amplified. -

VIII. TROUBLESHOOTING The LED doesn’t turn on. Test condition: power on, all DIP switch positions off, gain at full 1. Using a multi-meter, check CCW position, all 75 jumpers on, for 5V on the oscilloscope probing no inputs connected. points. If 5V are present, confirm All measures in V the LED is in the correct orientation. -
