Thank you for purchasing TOA’s Digital Power Amplifier Module.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe
operation.
• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or
cautions regarding safety.
• After reading, keep this manual handy for future reference.
• This equipment is not suitable for use in locations where children are likely to be present.
• An equipment installer and the person in charge of maintenance are required to fully understand the functions
and structure of this unit, then be aware of electrical and mechanical risks before work.
‌Before starting work, he or she should take possible measures to prevent occurrence of such risks.
Be sure to contact your nearest TOA dealer if you need to confirm unclear points about risk sources of this
unit.
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 first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
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.
• 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.
• 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.
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.

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 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.
• 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 VX-3000F’s cover,
as this may result in fire or electric shock.
• When replacing the fuse, be sure to use the supplied one. Using any other fuse than supplied may cause fire
or electric shock.

VX-030DA: Blade 20 A
VX-050DA: Blade 30 A
• Be sure to switch off the amplifier’s power when replacing the fuse.
Inserting or removing the fuse with the amplifier’s power on may cause personal injury.
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
When Installing the Unit
• Do not block the ventilation slots in the VX-3000F’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.
• 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.
• Note correct polarity (positive and negative orientation) when connecting the power supply cord. Reversed
polarity connections will cause damage to the unit.
• To avoid electric shocks, be sure to switch off the VX-3000F’s power when connecting the unit.
When the Unit is in Use
• 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.
Tip: VX-3004F, VX-3008F, and VX-3016F are collectively referred to as “VX-3000F” in this manual.
2. GENERAL DESCRIPTION
The VX-015DA, VX-030DA, and VX-050DA are Digital power amplifier modules used for the VX-3000 system.
They are module types with 1 channel of class-D digital power amplifier, which contributes to energy-saving
and light weight design.
The VX-015DA, VX-030DA, and VX-050DA also feature standby mode to be set for reducing standby power
consumption.
They require VX-3000F control unit and VX-3000DS (or VX-3150DS) power supply unit.
3. Installation Procedure
WARNING
There is a high voltage section inside the power amplifier's filter. Never
insert your finger or metallic objects inside the unit. When attaching or
detaching the connector, never touch the internal components other
than connectors.
Step 1. Shut off the power of the VX-3000F unit.
Shut off the power when the power is supplied to
the VX-3000F unit.

Step 2. Detach the front panel of the VX-3000F unit.
Remove 4 fixing screws for front panel and detach
the front panel.

Step 3. Install this digital power amplifier module.
Insert the digital power amplifier module along the
supporting runner until it will not go any further,
then secure it using a power amplifier fixing screw.
Note
Use a #2 bit Philips screwdriver to tighten the fixing
screw.
Step 4. Lift the lower portion of the filter of the VX-3000F
unit, then connect cables.
4-1. Connect both the power amplifier module's DA
control link connector and DA output link connector
to the VX-3000F's corresponding connectors.
Use the cables supplied with the power amplifier
module.
Note
After the cable connection is complete, be sure
to push the cables against the amplifier side to
prevent them from protruding so that the front panel
can be easily mounted without obstructing its work.
