The Group 1 signal goes to Stereo L and the Group 2 signal goes to Stereo R. 4 Master SEND (AUX1 and AUX2 Controls) Adjust the signal level, respectively. These are the signals that are output to the AUX1 and AUX2 SEND jacks. 5 RETURN (AUX1, AUX2, and ST Controls) • AUX1 and AUX2 Controls Adjust the level of the mixed L/R signal sent from the RETURN jacks (L (MONO) and R) to the AUX1 and AUX2 buses. • ST Control Adjust the level of the signal sent from the RETURN jacks (L (MONO) and R) to the Stereo bus. NOTE If you supply a signal to the RETURN L (MONO) jack only, the mixer outputs the identical signal to both the L and R Stereo buses. 6 2TR IN Control Adjusts the level of the signal sent from the 2TR IN jack to the Stereo bus. 7 PHANTOM +48 V Switch This switch toggles phantom power on and off. If you set the switch on, the mixer supplies power to all channels that provide XLR mic input jacks (CHs 1-8, 9/10, 11/12 on MG16/4, 1-4, 5/6, 7/8 on MG12/4). Set this switch on when using one or more condenser microphones. NOTE When this switch is on, the mixer supplies DC +48 V power to pins 2 and 3 of all XLR-type MIC INPUT jacks. • Be sure to leave this switch OFF when you are not using phantom power. Humming or damage may result if you connect to an unbalanced device or to an ungrounded transformer while this switch is on. But note that the switch may be left on without problem when connecting to balanced dynamic microphones. • To avoid damage to speakers, be sure to turn off amplifiers (or powered speakers) before turning this switch on or off. 20 MG16/4, MG12/4
