L/R pair of inputs to each L/R pair of outputs. In addition to the 4 input and 2 output channels on the Shaka-8, the Matrix may be expanded to a 4x3, 4x4 or more matrix mixer by chaining Shaka-4 Stereo Matrix Expanders to the main unit via the 12-pin connector labeled “EXPANDER”...

Assembly Instructions (Shaka-8): 1. Gather your materials. Make sure you have good quality solder on hand, your solder is set to the correct temperature, and you have a decently clean workspace upon which to solder. 2. Solder the 8x Film Capacitors (numbered C29-C36) in their footprints on the front of the PCB, as indicated by the silkscreen boxes.

Assembly Instructions (Shaka-4): Assembly of the Shaka-4 is very similar to that of the Shaka-8 and uses mostly the same parts, but has fewer steps. As there are no capacitors, start with soldering the two Expander I/O headers as described in Step 4 of the Shaka-8 build guide, then follow the remaining instructions but apply them to the Shaka-8 BOM.

6. If every matrix point is functional and working the same, congratulations! You have completed your Shaka-8 build. 7. If you have built a Shaka-8 expander, be sure to connect it to the main Shaka-8 or preceding Shaka-4 unit with the red stripe of the cable facing downwards. Then, power on your system and test the Matrix Points of the Shaka-4 in the same way as described in Steps 2-4 above.
