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.
