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.
