Front & Rear Panels 6 PRE Switch Selects whether the pre-fader or the post-fader signal is fed to the AUX bus. If you set the switch on ( ), the mixer sends the pre-fader signal (the signal prior to passage through channel fader B) to the AUX bus, so that AUX output is not affected by the fader. If you set the switch off ( ) the mixer sends the post-fader signal to the AUX bus. 7 EFFECT Controls Adjusts the level of the signal sent from the channel to the EFFECT bus. Note that the signal level to the bus is also affected by the fader. If you are using stereo channels (CHs 5/6, 7/8, 9/10, or 11/12), the signals from the L (odd) and R (even) channels are mixed and then sent to the EFFECT bus. 8 PAN Control (1 to 4) PAN/BAL Control (5/6 and 7/8) BAL Control (9/10 and 11/12) The PAN control determines the positioning of the channel's signal on the Group 1 and 2 buses or on the Stereo L and R buses. The BAL control knob sets the balance between left and right channels. Signals into to the L input (odd channel) feed to the Group 1 bus or to the Stereo L bus; signals into the R input (even channel) feed to the Group 2 bus or the Stereo R bus. NOTE On channels where this knob provides both PAN and BAL controls (5/6 and 7/8), the knob operates as a PAN control if you are inputting through the MIC jack or into the L (MONO) input only, and operates as a BAL control if you are inputting into both L and R inputs. 9 ST Switch This switch assigns the channel's signal to the Stereo L and R buses. To send the signal to the Stereo bus, set the switch on by pressing it in ( ). The switch lights up orange to indicate that it is on. 0 PFL (Pre-Fader Listen) Switch This switch lets you monitor the channel's pre-fader signal. To set the switch on, press it in ( ) so that it lights up. When the switch is on, the mixer outputs the channel's pre-fader signal to the PHONES and C-R OUT jacks, for monitoring. A GROUP Switch Use this switch to assign the channel's signal to the Group output. Press the switch in ( ) to output the signal to the Group 1 and 2 buses. NOTE Allows you to output the signal to the buses regardless of the setting of the ST switch 9. B Channel Fader Adjusts the output level of the signal being input to the channel. Use these faders to adjust the volume balance among the various channels. NOTE To reduce noise, set the fader sliders for unused channels all the way down. 18 MG12/4FX
