… So you would connect it all like this:
<i>Guitar → H90 Input 1</i>
H90 output 3 → IRX input
IRX output → H90 input 3
H90 output 1 to FRFR/ desk/ amp ..
The IRX send does not have an IR on it so it will sound bad. The output does.
With the connections above and with the H90 set to insert mode, you can put the IRX anywhere in the signal chain.
Simples INNIT! You must think about signal flow. Your connection above has outputs running into outputs ….. No signal flow.
