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.
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.
• 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.
• Use nuts and bolts that are appropriate for the
ceiling's or wall's material and structure. 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.
• (Applicable to H-3 only)
Since the unit is designed for in-door 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.
• Do not apply lubricant and rust inhibitor. If it
contacts resin or rubber parts, they could
deteriorate and cause the unit to fall, possibly
resulting in personal injury.
• (Applicable to H-3WP only)
Avoid installing the unit in locations close to the
seashore, or in indoor swimming pools or
bathrooms. In such locations, the bracket may be
vulnerable to corrosion, eventually allowing the
unit to fall resulting in personal injury.
• Avoid touching the unit's sharp metal edge to
prevent injury.
• 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 fire.
WARNING
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.

2. GENERAL DESCRIPTION
TOA's H-3 and H-3WP are wall-mounted 2-way speakers featuring wide horizontal dispersion.
The H-3 is designed for indoor use, and the H-3WP is designed for outdoor use.
Note: Protect the H-3WP from rain when installing. (Refer to p. 10 "Waterproofing the base frame.")
3. FEATURES
• Smooth curved surface blends in with the interiors of most modern buildings.
• Wide horizontal dispersion covers wide areas when mounted on the wall.
• Two 10 cm woofers featuring high input capacity ensure powerful, low distortion low-frequency sound
reproduction.
• 2.5 cm soft dome tweeter employs a neodymium magnet for clear, low distortion high-frequency sound
reproduction and high power-handling capability.
• Built-in crossover network circuitry features sharp cut-off characteristics that realize uniform energy radiation
while suppressing unwanted input signals to the woofer or tweeter.
• Two lock tabs secure the enclosure to the supplied base frame. The base frame can be mounted directly to
a 2-unit electrical box.
• A built-in matching transformer permits the speaker to be used for both high- and low-impedance
applications. For low-impedance applications, either the 8 Ω terminal or 16 Ω terminal can be selected.
Impedance can be easily changed from outside the unit.
• Detachable input connectors with dual positive and negative terminals for bridge connections.
• Enclosure is made of fire-resistant ABS resin (UL Standard 94V-0 Grade).
• Front grille is specially designed for ease of refinishing and repainting.
