L/R pair of outputs. In addition to the four input and two output channels on the Shaka-8, the Matrix can be expanded to a 4x3, 4x4, or more Matrix Mixer by chaining the Shaka-4 Stereo Matrix Expanders to the main unit via the 12-pin connector labeled “EXPANDER”...

To power the main Shaka-8 unit, connect a standard 2.54mm pitch 10-to-16 pin ribbon power cable to the header at the top of the Shaka-8 pdb. The -12V/red stripe side of the connector must be aligned with the white stripe indicator labeled “-12V” for proper use. (The red on the rainbow colored ribbon is the -12V “red stripe”).
Theory of Operation: The Shaka-8 and Shaka-4 are affordable, high quality Matrix Mixers with Voltage-Control over Matrix patch points. These modules operate in much the same way as a typical stereo audio matrix mixer, with the send level of each input to each output controlled by the corresponding knob, and the resulting “mix”...
