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.

Step 1-1. Run the speaker cables from the wall through the base frame hole (21.6 mm in diameter), then strip the cables about 5 mm from the cable end.

• Usable cable: Solid or stranded cable (0.2 – 2.5 mm 2 corresponding to AWG24 – 14)

Step 1-2. Mount the base frame on the wall using four screws.

Notes

• The speaker cannot be mounted if the base frame is not properly positioned. Ensure that the base frame hole is situated on the upper side of the frame when mounted.

• Use nuts and bolts (not supplied with the unit for direct wall mounting) that are appropriate for the structure and composition of the wall.

• When using two-gang electrical box, use either the supplied "M4 machine" or "Unified" screw depending on the type of electrical box.

• Protect the H-3WP from rain when installing it outdoors. (Refer to p. 10 "Waterproofing the base frame.")

7. OUTDOOR USE (H-3WP ONLY)

7.1. Installation Precautions

• The H-3WP features drip-proof construction for permanent outdoor installation. However, do not dash water over it when cleaning as this may cause damage to the speaker components.

• When installing the H-3WP in a snowy area, protect the speaker so that it is not covered with snow.

7.2. Waterproofing the Base Frame

The H-3WP's base frame has a gasket for watertightness. To prevent water from getting into a gap between the base frame and wall, apply commercial caulking agent over the inside of the gasket before mounting the base frame.

Note

Take care not to apply too much caulking agent. If it spreads to the lock tab, the lock tab does not smoothly rotate and the speaker may not be mounted or detached.

8. REPAINTING THE FRONT GRILLE

Follow the procedures below to change the color of the grille:

Step 1. Wipe dirt off the front grille with a soft cloth moistened with a detergent before painting. Do not use volatile liquids such as thinner.

Step 2. Uniformly spray a thin coating of paint over the grille changing the spraying positions gradually.

Notes

• Do not use a roller or brush to paint because the grille mesh could be clogged with paint.

• Use paint that is appropriate for the material of the front grille (grille and frame).

[H-3] Grille: Rolled steel plate

Frame: Fire-resistant ABS resin

[H-3WP] Grille: Rolled steel plate (zinc plating)

Frame: Fire-resistant ABS resin

• Follow the instructions on the paint when painting.

Step 3. After the paint dries, repeat Step 2 to repaint.

Note

Be sure to repeat Step 2 at least twice. If you paint only once, the paint may not be uniformly applied or the grille mesh may be clogged.

9. PROTECTION CIRCUITRY INFORMATION

• The speaker's tweeter has built-in overload protection circuitry. (The woofer does not have the circuitry.)

If there is an extremely high level input signal to the tweeter, the overload protection circuitry is activated and cuts off the signal input to the tweeter.

• A sudden drop of the sound volume level during speaker operation indicates that the overload protection circuitry has been activated. In such a case, reduce the amplifier volume and wait. The protection circuitry is automatically reset after approximately ten seconds. After the circuitry is reset, set the volume at a lower level than before.

Caution

This overload protection circuitry does not completely protect the tweeter. Depending on the nature of the excessive signal applied to the speaker, there may be damage to the speaker before the protection circuitry can operate. Also, depending on the duration of the excessive input signal, the protection circuitry may be damaged and will not recover. Take special care that the excessive input is not applied to the speaker during use.

10. EQUALIZATION

• The H-3 and H-3WP speakers are designed to provide good quality sound without additional signal processing. However, by equalizing them as shown below, sounds can be made more powerful and intelligible.

• Using a digital signal processor, use the following equalization settings.
