1. SAFETY PRECAUTIONS

Be sure to read the instructions in this section carefully before use.

Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important precautions are included.

We also recommend you keep this instruction 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.

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

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 the H-3WP in locations where the temperature is between –15 and +50°C. When installing in the snowy area, take appropriate measures to prevent snow from lying on the unit. If the ambient temperature exceeds –15 or +50°C or if the snow lies on the unit, the unit may fall, causing personal injuries.

Use nuts and bolts that are appropriate for the wall's structure and composition. Failure to do so may cause the speaker to fall, resulting in material damage and possible personal injury.

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.

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 it is malfunctioning (no tone sounds.)

CAUTION

When the Unit is in Use

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 a fire.

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 feature a neodymium magnet which ensures powerful, low distortion low-frequency sound reproduction.

2.5 cm soft dome tweeter also 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 highand 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.

4. HANDLING PRECAUTIONS

To clean, wipe the unit with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral detergent. Never use benzine, thinner or chemically-treated towel, as this could damage the unit's form or finish.

Avoid using the H-3WP speaker on the beach because the speaker's life can be greatly shortened by sea breezes.
