Stereo input channels 5 I PRE (Pre-fader) switches These switches are used to select pre- or post-fader for signals sent from the stereo input channel to MIX buses 5–10. Each switch is effective for one pair of MIX buses:5/6, 7/8, or 9/10. When you turn these switches on, the pre-fader signals are sent to the corresponding MIX bus pair. J BAL (Balance) control This control is used to adjust the left and right balance of signals sent from the stereo input channel to the ST bus. K ST (Stereo)
