Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
CAUTION Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
as doing so may result in fire or electric shock.
Use the unit only with the voltage specified on
the unit. Using a voltage higher than that which is
specified may result in fire or electric shock.
Do not cut, kink, otherwise damage nor
modify the power supply cord. In addition, avoid
using the power cord in close proximity to
heaters, and never place heavy objects
including the unit itself on the power cord, as
doing so may result in fire or electric shock.
The terminals marked with the symbol are
hazardous live. The external wiring to these
terminals requires installation by an instructed
person.
The socket-outlet shall be installed near the
equipment and the plug (disconnecting device)
shall be easily accessible.
Be sure to replace the unit’s terminal cover
after connection completion. Because the
voltage of up to 100V is applied to the high
impedance speaker terminals, never touch these
terminals to avoid electric shock.
Be sure to ground to the safety ground (earth)
terminal to avoid electric shock. Never ground to
a gas pipe as a catastrophic disaster may result.
When Installing The Unit

x
x
x
x
x
Should the following irregularity be found
during use, immediately switch off the power,
disconnect the power supply plug from the AC
outlet and contact your nearest TOA dealer.
Make no further attempt to operate the unit in this
condition as this may cause fire or electric shock.
If you detect smoke or a strange smell coming
from the unit.
If water or any metallic object gets into the unit.
If the unit falls, or the unit case breaks.
If the power supply cord is damaged (expo
sure of the core, disconnection, etc.)
If it is malfunctioning (no tone sounds.)
To prevent a fire or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
your nearest TOA dealer.
Do not place cups, bowls, or other containers of
liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire
or electric shock.
Do not insert nor drop metallic object or
flammable materials in the ventilation slots of the
unit’s cover, as this may result in fire or electric
shock.

2. GENERAL DESCRIPTION
3. FEATURES
xHigh durability, high reability and high performance.
xFour (Five microphone on A-324DME-AS) microphone inputs, two AUX inputs and one recording output.
xSpeaker output of constant voltage distribution system (100V) & low impedance (4:).
xOperates on AC power.
xMuting function.
xIndependent input volume control and master volume control.
xIndependent tone control of boost and cut type for both high and low freuency.
xMIC 1 euipped with phantom power for condenser microphone and also option for Chime Microphone.
xCurrent limiter circuitry protects transistor and thermal protection circuitry prevent a failure due to overheat.
xAll MIC inputs are electronically-balanced input.
xAdditional features such as built in MP3 Player, one Selector and 5 Bands Eualier
xNever plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
xWhen unplugging the power supply cord, be sure
to grasp the power supply plug, never pull on
the cord it self. Operating the unit with a
damaged power supply cord may cause a fire or
electric shock.
x  When moving the unit, be sure to remove its
power supply cord from the wall outlet. Moving
the unit with the power cord connected to the
outlet may cause damage to the power cord,
resulting in fire or electric shock. When
removing the power cord, be sure to hold its plug
to pull.
xDo not block the upper panel ventilation slots in
the units cover. Doing so may cause heat to build
up inside the unit and result in fire.
xAvoid installing the unit in humid or dusty location,
in location exposed to direct sunlight, near the
heaters, or in location generating sooty smoke or
steam. As doing otherwise may result in fire or
electric shock.
xeep the distance for all side of units 10 cm away
from the obect that may obstruct air flow for inter -
nal units temperature rise prevention.
xDo not place heavy obect on the unit as this may
cause it to fall or break which may result in
personal inury and/or property damage. In addi -
tion, the obect it self may fall of and cause inury
and/or damage.
