Hello,

I’ve moved your comment to a new forum post so it’s easier for users to find this information.

You can use Insert mode to create a mirrored path of the H90’s signal path and output it to 1-2 and 3-4 simultaneously.

• Press the routing button and turn Quick Knob 3 all the way clockwise till you see “Stereo Insert”
• Turn Quick Knob 2 to adjust the position of the Stereo Insert until it is at the end of the signal chain
• Press the Routing button again and adjust the mix of the Stereo Insert to be 50%
• The H90’s full signal path will now be output to both 1-2 and 3-4.
