To do set up stereo in-ear mixbuses on the X32, select a mix bus and press HOME button near the screen. Press the first encoder to link the to the adjacent bus, just as you can with channels. Now when you use the BUS SEND encoders to send to those buses, the even encoder will be level and the odd encoder will be pan. For example: When sending to buses 1 and 2 after linking, bus send encoder 1 will be level and encoder 2 will be pan.
