6PRE Switch

Selects whether the pre-fader or the post-fader signal is fed to the AUX1 bus. If you set the switch on ( ), the mixer sends the pre-fader signal (the signal prior to passage though channel fader A) to the AUX1 bus, so that AUX1 output is not affected by the fader. If you set the switch off ( ) the mixer sends the post-fader signal to the AUX1 bus.

Note that this switch applies to AUX1 only. The signal to the AUX2 bus always passes through the channel fader ﬁrst.

7PAN Control (MG16/4: CHs 1 to 8.

MG12/4: 1 to 4.)

PAN/BAL Control (MG16/4: 9/10 and 11/12.

MG12/4: 5/6 and 7/8.)

BAL Control (MG16/4: 13/14 and 15/16.

MG12/4: 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.

On channels where this knob provides both PAN

NOTE and BAL controls (9/10 and 11/12 on the MG16/4; 5/6 and 7/8 on the MG12/4), 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.

8 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.

9PFL (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.

0GROUP Switch

Use this switch to assign the channel’s signal to the Group out- put. Press the switch in ( ) to output the signal to the Group 1 and 2 buses.
