1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instruction in this section for correct and
safe operation.
• Be sure to follow all the precautionary instruction in this section, which contain important warnings
and/or cautions regarding safety.
• After reading, keep this manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbol and messages describe 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.
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
When Installing the Unit
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted
surface. Doing so may result in the unit falling down and causing personal injury and / or property
damage.
• Install the unit only in location that can structurally support the weight of the unit and the mounting
bracket. Doing otherwise may result in the unit falling down and causing personal injury and / or
property damage.
• Since the unit is designed for indoor use, do not install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a
danger of electric shock.
• Owing to the unit's size and weight, be sure that at least two persons are available to install the unit.
Failure to do so could result in personal injury.
• Do not use other methods than specified to mount the bracket. If extreme force is applied to the unit,
the unit could fall off, resulting in personal injuries.
• Use screws that are appropriate for the ceiling's or wall's structure and composition. Failure to do so
may cause the unit to fall, resulting in personal injury.
• Ensure that all screws are securely tightened. If they are not tightened or firmly secured after
installation, the unit could fall down, possibly resulting in personal injury.
• Use the specified mounting bracket in combination. Doing otherwise may cause the unit or
component to fall off, resulting in personal injury.
• Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be
damaged by excessive vibration, potentially causing the unit to fall, which could result in personal
injury.
• 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 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 apparatus shall be connected to a main socket outlet with a protective earthing connection.
• Should the following irregularity be found during use, immediately turn off this unit's power switch,
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 power supply cord is damaged (exposure of the core, disconnection, etc.)
• If it is malfunctioning (no tone sounds.)

4
CAUTION
When Installing the Unit
• When unpacking or installing the unit, be sure to handle it with two or more persons. Falling or
dropping the unit may cause personal injury.
• Avoid touching the unit's sharp metal edge to prevent injury.
• To avoid electric shock, be sure to switch off the amplifier's power when connecting to other speakers.
• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric
shock.
• When unplugging the power supply cord, be sure to grasp the power supply plug never pull on the
cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
When the Unit is in Use
• Do not place heavy objects on the unit as this may cause it to fall or break which may result in
personal injury and/or property damage. In addition, the object itself may fall off and cause injury
and/or damage.
• Make sure that the volume control is set to minimum position before power is switched on. Loud
noise produced at high volume when power is switched on can impair hearing.
• Do not operate the unit for an extended period of time with the sound distorted. This is an indication
of a malfunction, which in turn can cause heat to generate and result in a fire.

1. Power Switch [ ON / OFF ]
Turning this switch on causes the amplifier to function, and turning it off causes the amplifier to
cease function.
Note : All input volume to be in the minimum position.
2. Power Indicator [POWER]
Lights green when the power switch is turned on.
3. Indicators [INPUT, OUTPUT, PEAK, PROTECT]

 Input Indicator [INPUT]
Lights green regardless of the input level control setting when an input signal level exceeds about –20 dB.
 Output Indicator [OUTPUT]
Lights yellow when an output level exceeds about 1 W at an 8Ωload
 Peak Indicator [PEAK]
Lights red when an output signal clips (distortion occurs).
Note : When the Peak indicator is lit, turn the input level control counterclockwise until its light
extinguishes or decrease the input signal level of the connected external device. Operating the unit
while the Peak indicator remains lit may cause the protection circuitry to be activated.
 Protection Indicator [PROTECT]
Lights red when the protection circuitry is activated. (See p. 7; Protection Operation List.) When the
power is switched on, this indicator lights for about 2 seconds and then extinguishes.
4. Master Volume Control

10.1.5. Safety wire installation [ For speaker fall prevention ]
When mounting the speaker system to the ceiling or wall, install a safety wire as needed.
When installing the safety wire, be sure to follow the instruction below.
Failure to do so may cause the speaker to fall, resulting in personal injury.
Use a wire rope of 2mm(0.08”) or more in diameter. (The safety wire is not supplied.)
Tighten the safety wire to take up the slack. Otherwise, impact shock at speaker fall may cause the
Wire connected parts or wire itself to break.
Install the safety wire to a place that can structurally support the full weight of load.
Screw a speaker suspension bolt (M8) into one of the screw holes on the speaker's bottom surface.
Then, connect the safety wire to the bolt.
