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!
