• If you’ve turned off the phantom power master setting in the
SETUP screen SYSTEM SETUP field, phantom power will
not be supplied even if the +48V button is turned on for each
channel.
NOTE
• If you don’t need phantom power, be sure to turn this button
off.
• Before you turn phantom power on, make sure that no
devices other than phantom-powered devices, such as a con-
denser microphone, are connected. Otherwise, you risk dam-
aging the devices.
• Do not connect or disconnect a device while phantom power
is applied. Doing so can damage the connected device and/or
the unit itself.
•To protect your speaker system, leave the power amps (pow-
ered speakers) turned off when switching the phantom power
on/off. We also recommend that you set all output level faders
to the minimum position. Otherwise, high-volume output may
damage your hearing or equipment.
