ACL M/S Matrix is a logic module for modular synthesizers in Eurorack format. With the module, conventional L/R stereo signals can be converted into M/S format, the center and side can be changed separately by external processing steps and then converted back again. All inputsd of the ACL M/S Matrix are equipped with volume controls, so that level changes occurring during processing can be easily compensated. The module has two sections: The first stage has inputs plus level controls for left and right stereo signals. Internally, the material is converted to M/S format and then outputted by the appropriate outputs. The second section works the other way around. Here, center and side signals can be fed in, processed in their volume and converted into L/R format.
