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 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.
• 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. Extreme force is applied to the unit
and the unit could fall off, possibly resulting in
personal injuries.
• Use a cable of AWG 16 or thicker (VP-1061 and
VP-1121) or AWG 12 or thicker (VP-1241 and VP-
1361) for connecting to the 24 V DC POWER IN
terminal. Also, be sure to firmly screw the cable to
the terminal. Failure to do so may cause the cable
to generate heat, possibly resulting in fire.
• The socket-outlet shall be installed near the
equipment and the plug (disconnecting device)
shall be easily accessible.
• The apparatus shall be connected to a main socket
outlet with a protective earthing connection.
• The terminals marked with the symbol are
hazardous live. The external wiring to these
terminals requires installation by an instructed
person.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately 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 (exposure 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
qualified 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 fire
or electric shock.
• Do not insert nor drop metallic objects or
flammable materials in the ventilation slots of the
unit's cover, as this may result in fire or electric
shock.
• Do not touch a plug during thunder and lightning,
as this may result in electric shock.
• When replacing the fuse, be sure to use the
supplied one or equivalent. Doing otherwise may
cause fire or 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 fire or electric
shock.

2. GENERAL DESCRIPTION
The VP-1061 (60 W), VP-1121 (120 W), VP-1241 (240 W), and VP-1361 (360 W) are 1-channel Power
Amplifiers designed exclusively for rack mount use.
3. FEATURES
• Both the VP-1061 and VP-1121 are 2U* half rack size amplifiers, mountable either alone or side-by-side in a
19" rack.
• Both the VP-1241 and VP-1361 are 3U* full rack size amplifiers.
• Operate on either 230 V AC or 24 V DC.
• An optional YA-1000A Fault Detection Circuit Module can be installed.
• Equipped with Program and Priority inputs, volume level of Program input can be attenuated whenever the
Priority input receives a signal. Attenuation of the volume level is adjustable.
• Input terminals employ removable terminal blocks to provide maximum connection ease.
* 1U size = 44.5 mm (standard size)
4. HANDLING PRECAUTIONS
• It is recommended that the unit be always used in locations where the ambient temperature ranges from 0 to
+40 °C and humidity is less than 90% (no condensation).
• When cleaning the unit, be sure to disconnect the power supply plug from the AC outlet. Wipe with a soft dry
cloth. If it gets very dirty, use the soft cloth slightly moistened in neutral cleanser. Never use thinner,
benzene, chemically processed towels, or alcohol as the unit's plastic or other parts may be deformed or
discolored.
• When moving the unit, be sure to remove its power
supply cord from the AC outlet. Moving the unit
with the power supply cord connected to the outlet
may cause damage to the power supply 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.
• 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.
• When unpacking or moving the unit, be sure to
handle it with two or more persons. Falling or
dropping the unit may cause personal injury and/or
property damage.
• To avoid electric shocks, be sure to disconnect the
power supply plug from the AC outlet when
connecting speakers.
• Be sure to follow the instructions below when rackmounting 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.
· 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
• 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 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.
• 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.
