Press “MIX” on the Main L/R channel, then press and hold down the “assign”-button (located between the two fader-banks) while pressing “MIX” on the group you want to send to L/R.
You will then se “ON” in the group name/ch-window.
As far as i know there is no SIP, but you can P(A)FL the signal by holding down the “Sel”-key for the preamp, the EQ, comp and so on, to monitor the signal in various places of the chain in your headphones.
It’s possible that this signal can be routed to one of the outputs, but i have never tried it Anyone else?
