Turning On The Power - Boss RC-30 Owner's Manual

NOTE
* To prevent malfunction and/or damage to
speakers or other devices, always turn down the
volume, and turn off the power on all devices
before making any connections.
* Before connecting or disconnecting any
connection cables, be sure all the volume controls
in your system are set to minimum.
* Use connection cables that do not contain a
built-in resistor. If you use cables that contain a
resistor, there might be insufficient volume from
the device connected to the AUX IN jacks, or it
might be inaudible.
* Do not connect headphones to the OUTPUT jack.
Doing so may damage the headphones.
Caution when using a microphone
* Howling could be produced depending
on the location of microphones relative
to speakers. This can be remedied by:
• Changing the orientation of the
microphone(s).
• Relocating microphone(s) at a greater
distance from speakers.
• Lowering volume levels.
* If the amp and microphone are close
together, the sound played back from
the amp may be picked up by the
microphone. If you record or overdub in
such a state, the amp playback picked
up by the microphone will also be
recorded. You should separate the amp
and microphone so that the playback
from the amp is not picked up by the
microphone.

Turning On the Power

the power to the unit.
Once the connections have been completed, turn on power

devices in the wrong order, you risk causing malfunction
and/or damage to speakers and other devices.

memory operation is occurring)
* Always turn the phantom power off
when connecting any device other
than condenser microphones that
require phantom power. You risk
causing damage if you mistakenly
supply phantom power to dynamic
microphones, audio playback devices,
or other devices that don't require
such power. Be sure to check the
specifications of any microphone you
intend to use by referring to the manual
that came with it.
