• 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.

• 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 fire or
electric shock.

• To avoid electric shocks, be sure to switch off the

unit's power when connecting speakers.

• The unit is designed exclusively to be mounted in

an equipment rack. Be sure to follow the
instructions below when rack-mounting the unit.
Failure to do so may cause a fire or personal injury.

· Install the equipment rack on a stable, hard floor.

Fix it with anchor bolts or take other arrangements
to prevent it from falling down.

· Be sure to use the screws with a diameter of over

5 mm (0.2") and length of over 12 mm (0.47") to
mount the unit.

· When connecting the unit's power cord to an AC

outlet, use the AC outlet with current capacity
allowable to the unit.

When the Unit is in Use

• With the High-pass filter jumper socket kept to the

OFF position (factory preset), operating the unit for
long periods of time while the Peak indicator is
illuminated due to excessive input signal may
damage the connected speakers, possibly resulting
in fire. Operating the unit with the High-pass filter
jumper socket set to the ON position may decrease
the possibility of speaker damage or fire due to
excessive input signal.

• Make sure to set all input level controls to ∞ (infinity)

position before power is switched on.
Loud noise produced when power is switched on
with any of those controls set to the position other
than ∞ position can impair hearing.

• 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 fire.

• 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.

• 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.

• Turn off this unit's power switch, 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.

The lighting flash with arrowhead symbol,
within an equilateral triangle, is intended
to alert the user to the presence of
uninsulated "dangerous voltage" within
the product's enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.
