This is how my setup is connected: Guitar → H90 In 1 H90 Out 2 → IR-X INPUT IR-X BALANCED OUT → H90 In 2 H90 Out 1/2 → Mixer With this setup, I have the opportunity to bypass the IR-x anytime.
If you connect the guitar to H90 In 1, you should be coming out of Out 3 to the IR-X, then back into the H90 on In 3 if you want the IR-X on Insert 1 of the H90. Then take Out 1/2 to your mixer.
