Precautions
• Do not allow water to enter this unit or allow the
unit to become wet. Fire or electrical shock may
result.
• Connect this unit's power cord only to an AC
outlet of the type stated in this Owner's Manual
or as marked on the unit. Failure to do so is a fire
and electrical 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.
• 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
damaged, 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 replace-
ment. 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 inspec-
tion, maintenance, or repair is necessary, contact
your dealer.
• Do not modify the unit. Doing so is a fire and
electrical shock hazard.
• When rack-mounting the unit, allow enough free
space around the unit for normal ventilation.
This should be: 30 cm at the sides, 30 cm behind,
and 40 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.
• This unit has ventilation holes at the rear to pre-
vent the internal temperature rising too high. Do
not block them. Blocked ventilation holes are a
fire hazard.
• Clean the contacts of the phone plug before con-
necting it to the SPEAKERS jack of this unit.
Dirty contacts may generate heat.
• Use only speaker cables when connecting speak-
ers to amplifier outputs. Using other types of
cables is a fire hazard.
Hold the power cord plug when disconnecting it
from an AC outlet. Never pull the cord. A dam-
aged power cord is a potential fire and electrical
shock hazard.
• Do not touch the power plug with wet hands.
Doing so is a potential electrical shock hazard.
• The digital circuits of this unit may induce a
slight noise into nearby radios and TVs. If noise
occurs, relocate the affected equipment.
• Using a mobile telephone near this unit may
induce noise. If noise occurs, use the telephone
away from the unit.
• XLR-type connectors are wired as follows: pin 1:
ground, pin 2: hot (+), and pin 3: cold (-).
• Do not set all equalizer controls and faders to
maximum. Doing so may cause oscillation
depending on the condition of the connected
unit and speakers, and may damage the speakers.
• The performance of components with moving
contacts, such switches, rotary controls, faders,
and connectors, deteriorates over time. The rate
of deterioration depends on the operating envi-
ronment and is unavoidable. Consult your dealer
about replacing defective components.
