EMX88S/EMX68S—Owner’s Manual
Precautions
WARNING
• 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 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.
• 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.
• Use only the included power cord for this unit. Using other
types may be a fire and electrical shock hazard.
• The power to this device is not completely shut off even when
the power switch is turned off. Locate the device close to the AC
outlet so you can easily reach the power plug.
• Do not scratch, bend, twist, pull, or heat the power cord. 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, maintenance, or repair
is necessary, contact your dealer.
• Do not modify the unit. Doing so is a fire and electrical 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.
• 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.
• 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 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. Con-
sult your dealer for repair. Using the unit in this condition is a
fire and electrical shock hazard.
CAUTION
• Hold the power cord plug when disconnecting it from an AC
outlet. Never pull the cord. A damaged power cord is a poten-
tial fire and electrical shock hazard.
• Do not touch the power plug with wet hands. Doing so is a
potential electrical shock hazard.
• This unit has ventilation holes at the rear to prevent the internal
temperature rising too high. Do not block them. Blocked venti-
lation holes are a fire hazard.
• When rack-mounting the unit, allow enough free space around
the unit for normal ventilation. This should be10 cm at the
sides, 15 cm behind, and 25 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.
• Use only speaker cables when connecting speakers to amplifier
outputs. Using other types of cables is a fire hazard.
• Clean the contacts of the phone plug before connecting it to the
SPEAKERS jack of this unit. Dirty contacts may generate heat.
• XLR-type connectors are wired as follows: pin 1: ground, pin 2:
hot (+), and pin 3: cold (-).
• 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
environment and is unavoidable. Consult your dealer about
replacing defective components.
• Using a cell phone (mobile telephone) near this unit may induce
noise. If noise occurs, use the telephone away from the unit.
• 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.
