Precautions
• Use only the included power cord for this unit. Using
other types may be a fire and electrical shock hazard.
• Do not allow water to enter this unit or allow the unit
to become wet. Fire or electrical shock may result.
• Do not place a container with liquid or small metal
objects on top of this unit. Liquid or metal objects
inside this unit are a fire and electrical shock hazard.
• Connect the included power cord only to an AC out-
let of the type stated in this Owner’s Manual or as
marked on the unit. Failure to do so is a fire and elec-
trical shock hazard.
• Do not scratch, bend, twist, pull, or heat the power
cord. A damaged power cord is a fire and electrical
shock hazard.
• Do not place heavy objects, including this unit, on
top of the power cord. A damaged power cord is a
fire and electrical shock hazard. In particular, be
careful not to place heavy objects on a power cord
covered by a carpet.
• Place the device near a power outlet so you can eas-
ily plug it in.
• If you notice any abnormality, such as smoke, odor,
or noise, or if a foreign object or liquid gets inside the
unit, turn it off immediately. Remove the power cord
from the AC outlet. Consult your dealer for repair.
Using the unit in this condition is a fire and electrical
shock hazard.
• Should this unit be dropped or the cabinet be dam-
aged, turn the power switch off, remove the power
plug from the AC outlet, and contact your dealer. If
you continue using the unit without heeding this
instruction, fire or electrical shock may result.
• If the power cord is damaged (i.e., cut or a bare wire
is exposed), ask your dealer for a replacement. Using
the unit with a damaged power cord is a fire and
electrical shock hazard.
• Do not remove the unit’s cover. You could receive an
electrical shock. If you think internal inspection, main-
tenance, or repair is necessary, contact your dealer.
• Do not modify the unit. Doing so is a fire and electri-
cal shock hazard.
• If lightning begins to occur, turn off the power switch
of the unit as soon as possible, and unplug the power
cable plug from the electrical outlet.
• If there is a possibility of lightning, do not touch the
power cable plug if it is still connected. Doing so may
be an electrical shock hazard.
• Turn off all audio equipment, and speakers when
connecting to this unit. Use the correct connecting
cables and connect as specified.
• Do not subject the speaker to excessive levels, or dis-
torted sounds (indicated by the clip indicator lighting
up often) as this leads to overheating and a possible
fire hazard.
• Always lower the volume control to minimum before
turning on the power to this unit. A sudden blast of
sound may damage your hearing.
• When rack-mounting the unit, allow enough free
space around the unit for normal ventilation. This
should be: 20 cm at the sides, 25 cm behind, and 30
cm above.
For normal ventilation during use, remove the rear of
the rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up
inside and may cause a fire.
• Do not use the handles to suspend the speaker. Oth-
erwise, it may fall, causing injury.
• Hold the power cord plug when disconnecting it
from an AC outlet. Never pull the cord. A damaged
power cord is a potential fire and electrical shock
hazard.
• This unit is heavy. Use two or more people to carry it.
• Do not touch the power plug with wet hands. Doing
so is a potential electrical shock hazard.
• XLR-type connectors are wired as follows: pin 1:
ground, pin 2: hot (+), and pin 3: cold (–).
• Using a mobile telephone near this unit may induce
noise. If noise occurs, use the telephone away from
the unit.
• Do not use the speakers at uncomfortably loud level.
Otherwise, you may damage your hearing.
• Subwoofer SW500 comes with a metal socket for
installing the speaker stand. Use a speaker stand pole
that is one meter or shorter.
Troubleshooting
—If the unit shuts down during use—
If the CLIP indicator lights up often and you use this
unit for a long period of time, the thermostat inside
the power transformer will turn the power off. In
this case, turn the POWER switch off, wait for a
while (about one hour) until the the power trans-
former cools down, then resume using the unit at a
lower input level.
Be sure to lower the input level so that the CLIP
indicator lights up only momentarily.
