Description

We’re pleased to announce our take on matrix mixers, a 6x6 stereo matrix easily expandable to larger configurations.
Matrix mixers may need some time to get used to but they are very much self explanatory: each knob controls the volume of a matrix point routing the respective input to the desired output.
The flexibility of a matrix mixer is far superior to that of a standard mixer. The possibility to route any input to any single or multiple outputs allows for very complex chains, combining parallel and series processing while easily reconfigurable without any extra patching.

All Inputs Left channels are normalled to the Right Inputs.
Blank areas on the left and bottom edges of the panel allow for the user to write all the inputs and outputs sources that each channel is connected to.
Different colored knobs for faster visual recalling: Black for A,C,E Outputs Dark Red for B,D,F Outputs Cream knobs for potential feedback diagonal: 1A, 2B, 3C, 4D, 5E, 6F.
DC coupled circuitry, can be used to mix both audio or cv signals.
Jumpers on the back of both modules allow the user to set each channel independently to Line or Synth Level, making it easier to integrate with external sources, sound processors or guitar pedals.

INTERNAL CONNECTIONS
The control and input modules are connected via a large 34 wire ribbon cable, only the control module needs to be connected to the Busboard.
Extra IDC sockets are used for connecting larger configurations like 12x12 or 18x18.
Other configurations are also possible: 6x12, 12x6, 12x12, etc...
Up to 12x12 all ribbon cables are provided, for larger matrixes custom ones will be necessary, contact us directly if planning to go BIG.

POTENTIOMETERS
Although we're using Thonk's Tall Trimmer Topper for Knobs all potentiometers used have metal shaft and are not plastic trimmer potentiometers.

Tech Specs:
25HP + 8HP (33HP total)
4.5cm deep
140mA +12V
140mA -12V

Note: All specifications and features are subject to change without previous notice.
