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 rst and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
When Installing the Unit
• 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 re or electric shock.
• Use the unit only with the voltage specied on
the unit. Using a voltage higher than that which is
specied may result in re 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 re 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.
• 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.
• Apparatets stikprop skal tilsluttes en stikkontakt
med jord, som giver forbindelse til stikproppens
jord.
• Laite on liitettävä suojakoskettimilla varustettuun
pistorasiaan
• Apparatet må tilkoples jordet stikkontakt
• Apparaten skall anslutas till jordat uttag
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 re or electric shock.

· 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 (exposure of
the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds.)
• To prevent a re or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
qualied service personnel.
• 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 re
or electric shock.
• Do not insert nor drop metallic objects or ammable
materials in the ventilation slots of the unit's cover,
as this may result in re or electric shock.
• Do not touch a power supply plug during thunder
and lightning, as this may result in electric shock.

When Installing the Unit
• 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 re or electric shock.
• 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 re 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 re. Also, periodically clean the
ventilation slots of dust.
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke
or steam as doing otherwise may result in re or
electric shock.
• To avoid electric shocks, be sure to switch off the
unit's power when connecting speakers.
When the Unit is in Use
• 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.
• Switch OFF the unit's power before turning the
phantom power switch ON or OFF. Operating
the switch without switching OFF the main power
could result in a large transient noise through the
speakers, potentially resulting in speaker failure.
• Avoid using phantom power when connecting an
unbalanced microphone to the MIC 1 input, as the
microphone fails.
• Do not connect any other equipment than the RC03 Remote Controller to the MX-6224D’s Remote
controller connection port.
If other equipment, such as a PC, hub or network
device, is connected to that port, the connected
equipment could be damaged.
• Do not operate the unit for an extended period of
time with the sound distorting. Doing so may cause
the connected speakers to heat, resulting in a re.
• Contact your TOA dealer as to the cleaning. If dust is
allowed to accumulate in the unit over a long period
of time, a re or damage to the unit may result.
• Be sure to follow the instructions below when rackmounting the unit. Failure to do so may cause a re
or personal injury.
· Install the equipment rack on a stable, hard oor.
Fix it with anchor bolts or take other arrangements
to prevent it from falling down.
· When connecting the unit's power cord to an AC
outlet, use the AC outlet with current capacity
allowable to the unit.
• If dust accumulates on the power supply plug or
in the wall AC outlet, a re 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 re or electric
shock.

Tips
• The unit is designed for a total impedance to be greater than the indicated value (42 Ω) when high-impedance
100 V line speakers are connected to each speaker terminal and the total wattage is less than 240 W.
• The unit can produce optimum sound quality conditions when the following TOA speakers are connected and
the speaker equalizer function is used. (see p. 21.)
For ROOM zone: BS-1030B, BS-1030W
For OUTSIDE zone: TC-631M, TC-651M
Failure to do so could result in electrical shocks, as a high voltage is
applied to the speaker terminals. Also, take care to NEVER touch the
speaker terminals.

9.7. Extension Power Amplifier Connections
The unit is designed for connection to high-impedance 100 V line speakers, adding up to a total wattage of
240 W each for OUTSIDE and ROOM use. However, if more speakers are required, the power amplier can
be extended.
The sound volume of speakers connected
to the extension power amplier is not
interlocked with the front panel-mounted
outside and room volume controls.
Adjust the volume using the extension
power amplier's volume control.
Tips
• Output from the preamplier output jacks is
not interlocked with the front panel-mounted
outside and room volume controls.
• Output from the preamplier output jacks is
interlocked with the outside and room zone
output switches.
• Since the speaker equalizer affects output
from the preamplier output jacks, connect the
designated speakers (see p. 21.) to the power
amplier when the speaker equalizer switch is
ON for the zone(s).
• For more information on connecting speakers to
the extension amplier and use of the extension
amplier, see the instruction manual enclosed
with the amplier.
