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.
• Be sure to replace the unit's terminal cover after
connection completion. Because the voltage of up
to 100 V is applied to the high impedance speaker
terminals, never touch these terminals to avoid
electric shock.
• 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 a 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.
• 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.
• Tighten each nut and bolt securely. Ensure that the
bracket has no loose joints after installation to
prevent accidents that could result in personal
injury.
When the Unit is in Use
• 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.

outlet, use the AC outlet with current capacity
allowable to the unit.
When the Unit is in Use
CAUTION
• 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.
When Installing the Unit
• Never plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
• 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.
• Contact your TOA dealer as to the cleaning. If dust
is allowed to accumulate in the unit over a long
period of time, a fire or damage to the unit may
result.
• 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.
• Do not block the ventilation slots in the unit's cover.
Doing so may cause heat to build up inside the unit
and result in fire. Also, periodically clean the
ventilation slots of dust.
• To avoid electric shocks, be sure to switch off the
unit's power when connecting speakers.
4
• If dust accumulates on the power supply plug or in
the wall AC outlet, a fire may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
• Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. Doing otherwise may cause a fire or electric
shock.
2. GENERAL DESCRIPTION
TOA's FS-7006PA (600 W) and FS-7012PA (1,200 W) are power amplifiers designed for 100 V line and high
impedance applications. By mounting an optional YA-7000 module in the power amplifier and connecting it to
a standby amplifier, the power amplifier can be automatically switched over to the standby amplifier if the
power amplifier fails, allowing broadcasts in progress to continue uninterrupted.
3. FEATURES
• A built-in limiter circuit limits current flow if there is an electrical overload, and a protection circuit that detects
the voltage and current disconnects the output if there is a short circuit. This protection circuit also
disconnects the output if the amplifier's internal temperature rises significantly.
• Front volume control offers convenient output volume adjustment.
• Control input can bypass the volume control mounted on the front panel to allow "Urgency" announcements
to be broadcast at maximum sound volume regardless of volume setting.
• Continuously variable air-cooling system adjusts fan speed according to the temperature in the amplifier's
heat sink. This variability ensures that cooling fan noise is minimized as much as possible under normal
usage conditions.
4. HANDLING PRECAUTIONS
• Keep input cables away from output cables. Installing both cables too close to each other can potentially
generate unwanted oscillation.
• Never connect 2 or more amplifiers to each other through their outputs, as this could cause the amplifiers to
fail.
• To clean, be sure to first switch off the amplifier power, then wipe with a dry cloth. When the amplifier is very
dirty, use a cloth moistened in a neutral cleanser. Never use any volatile liquids, such as benzene, thinner,
and chemically-treated towels, since the amplifier surface could be damaged.
5
5. INSTALLATION PRECAUTIONS
• To ensure proper ventilation and prevent excessive heat buildup, position the amplifier so that there is at
least 15 cm between the top and the ceiling, and at least 5 cm between the sides and any walls. Allow at
least 10 cm behind the amplifier to ensure that the fan air vent in the rear panel does not become
obstructed.

FS-7006PA/7012PA
• When mounting amplifiers in an equipment rack, allow at least 10 centimeters behind the amplifier to ensure
that the fan air vent in the rear panel does not become obstructed.
• Because the amplifier is heavy (24.8 kg for FS-7006PA, 35.4 kg for FS-7012PA), be sure to reinforce the
fittings used to fix the amplifier in place when mounting in a rack and requiring extra strenght.
• Rack mounting screws are not supplied with the amplifier. Use screws that are appropriate for the specific
type of rack used.

Notes
• The speaker output terminal is designed for high impedance/100 V line applications. Be sure to connect
high-impedance speakers.
• The total rated power input for the speakers must be less than the power amplifier's rated output power.
Connecting speakers that exceed the amplifier's rated output power could cause equipment failures.
• Standby amplifiers must be the same type as the main amplifiers, or a type larger than the main amplifier in
terms of rated output power. If the standby amplifier's rated output power is smaller than that of the main
amplifier, it could be damaged by overload.
• Standby amplifiers cannot be shared with other main amplifiers.
• Only 1 piece of FS-7006PA or FS-7012PA can be connected to the YA-7000's main amplifier input and
standby amplifier input. Never connect 2 or more amplifiers to each of these terminals, as the excessive load
could cause the amplifier to fail.

8. FAILURE INDICATION
The power amplifier is equipped with an indicator that alerts the user to equipment failures.
When this Fault indicator lights, it is likely that some problem has occurred with the equipment or wiring.
When the power indicator remains unlit, it is likely that the power amplifier is not operating correctly. If this
happens, first check to be sure that the power is being supplied correctly to the amplifier. If the power indicator
remains unlit even when the power is being supplied correctly, it is likely that some problem has occurred
inside the equipment. Contact your TOA dealer to arrange for diagnosis and repair.
The following causes can be considered when the Fault indicator lights:
Symptom
Possible Cause
Check/Remedy
FS-7006PA's or
FS-7012PA's Fault
indicator lights.
Output is not being provided correctly
because of a short in the output wiring.
Remove the output wiring and turn the
power on again. If the Fault indicator light
goes out, then the problem may be with
the wiring. Check the wiring to determine
where the problem may be.
If the indicator light does not go out, or if it
goes out but then lights again within a
short period of time, consider whether the
following may be the problem:
Equipment failure or excessive high
heat build-up inside the unit.
Check the following points if the indicator
automatically goes out within 30 minutes
after it has lit.
• Check installation conditions for
appropriate ventilation.
• Check the connected load capacity for
possible overload.
• Check to see if input and output cables
are installed close to each other.
If all of the above are found to be in
correct working order, then it is likely that
the equipment itself is malfunctioning in
some way.
Equipment failures can also be considered
if the indicator lights again within a short
period of time even if it has gone out once.
Request maintenance and repair action.
