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.
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.
