Si Performer and Si Expression feature both analog and digital inserts, whereas the Si Impact have digital inserts only.  There are a total of 22 inserts available on all models.  They can be used on individual channels, mix buss outputs, or matrix outputs.  This is done either with Analog (on Performer or Expression), using XLR mix outputs and ¼" TRS Line Inputs; or Digital (all Si mixers), using channels on option cards (MADI, Dante, BLU Link). Even though there are only 22 inserts available, they can be patched from any option card channel.  Channels shown will be the mixer's internal bus channel number; for example, Slot 1 is bus channels 1-64 and Slot 2 is 65-96.

Assigning and Using an Insert

Select a channel, mix buss out, or matrix out.  Select Insert from touch screen.  Next, you must assign the patches for the inserts. Select Insert Setup:

Select an Insert and assign the Send and Return channel.  First is an example of Digital insert using Slot 2, channel 1.  This shows as a Bus or Insert channel 65:

​ 

Next is an example of Insert 2 being assigned XLR 1 out and Line 1 in.  Remember, this is NOT available on Si Impact:

​ 

Returning to the Insert Assign screen, we can now assign Insert 1 to Input channel 1.  Channel inserts are all Pre-EQ - meaning the insert point is placed between the Compression and EQ processing - and cannot be changed:

Here is the analog Insert 2 we patched earlier assigned to Mix 1. Notice that on the Mix Busses you have the choice of Pre-EQ, Post-EQ (but Pre-fader), and Post-fade.  Matrixes have the choice of Pre-EQ and Post-EQ, no Post-fade.

The finished patch and insert looks like this:

​

NOTE- You cannot turn the Insert on each channel on or off, it must be un-assigned from the channel.
