CAUTION
Before making connections, turn this unit and all equipment
to be connected off (standby).
The phantom power switches set four input channels at a
time. Do not set phantom power to +48V when connecting
a mic that does not require phantom power.
Before changing a phantom power switch setting, set the
LINE OUT 1–2 and PHONES 1/2 knobs to their minimum
values. Failure to do so could cause sudden loud noises from
monitoring equipment, and this could damage equipment
or harm hearing.
Do not connect or disconnect mics when a PHANTOM
switch is set to +48V. Doing so could cause a loud noise and
might damage this unit and connected equipment.
Set the PHANTOM switch to +48V only when using a
condenser microphone that requires phantom power.
Turning phantom power on when a dynamic mic or other
mic that does not require it is connected could damage this
unit and connected equipment.
When using condenser mics that require phantom power
and dynamic mics together, be sure to use balanced
dynamic mics. Unbalanced dynamic mics cannot be used
when phantom power is enabled .
Supplying phantom power to some ribbon mics will break
them. If you are unsure, do not supply phantom power to a
ribbon mic.
