How to use Matrixes on Si Mixers​​​​

Si mixers have four Matrixes, each can be either Mono or Stereo.  There is no need to “link” Matrixes to achieve stereo output, they just need to be assigned to an output.

Patching and Operating Matrixes

By default Matrixes are set to mono, but can be configured to stereo.  After selecting a Matrix, select “Outputs” on the display screen, then select “Mix Width”.  This option allows you to configure mono or stereo output. From this menu, you can route the outputs under “Patching”.  In the example below, we have patched Matrix 1 to outputs 15 & 16 at the rear of the mixer, replacing the Main Left and Right output.

Matrixes can be fed from either Aux Bus outputs, or L&R/Mono outputs.  To select Matrix mix contributions from Aux Buses, click on the “Matrix Fader Follow" button once.  Here we see Aux mixes being brought into Matrix 1.

To select Matrix mix contributions from L&R and Mono, click on “Matrix Fader Follow" button a second time, or two presses total.  Here we see L&R brought into Matrix Mix 1, which essentially gives you a duplication of L&R with its own processing.  Make sure to pan Left to the Left side and pan Right to the Right side. ​

 ​Note- At the time of this writing, the Left fader is marked as “L&R". This is incorrect and it should be labelled “Left"
