This switch toggles phantom power on and
off. If you set the switch on ( ), the
AUDIOGRAM supplies phantom power to
the MIC/INST jack (XLR-type)

. Tu rn this
switch on when using a phantom-powered
condenser microphone.
• Be sure to leave this switch off
() if you do not need phantom
power.
• When turning the switch on, be
sure that only a condenser micro-
phone is connected to the MIC/
INST input jack. Other devices
may be damaged if connected to
phantom power. This precaution
does not apply to balanced
dynamic microphones or instru-
ments with the phone jack, how-
ever, as these will not be affected
by phantom power.
•To prevent damage to speakers,
be sure to turn off audio system
(monitor speakers) before turn-
ing this switch on or off. We also
recommend that you set the OUT
LEVEL control to the minimum
position. Neglect of these pre-
cautions may result in large
noise bursts that may damage
your equipment, your ears, or
both.
