new project: video matrix mixer 4x3

Post by FetidEye » Fri Dec 06, 2019 3:55 pm

I have made a video Matrix mixer!
You can use this for color mixing, feedback patches, soft keying effects, subtractive and additive functions and more!
The pcb & panel are 14HP and are sandwiched together, suitable for shallow cases.
Suitable for the LZX video format.
The matrix mixer is open source. All components are through hole.

Examples:

Features:
4 inputs (input1, input2, input3, inverted input)
3 outputs (output1, output2, output3)
Each channel has its own potmeter, so 12 pots in total.

Mod options:
Gain pots for each column (pads for expansion)
3x gain for each channel (recommended mod. keying and feedback)

Prices:
PCB & Panel: 30 euro
Kit: 120 euro
Build module: 160 euro
shipping depends on the weight :)
PM me for details

I couldn't agree more about both this and the triple function generator!
Keep up the good work Martijn!

Utility modules are the inexpensive, dull polish that makes the expensive, shiny modules actually shine!!!

an oscillator is an oscillator - utilities are possibilities
