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.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could

result in death or serious personal injury.

When Installing the Unit

Refer all installation work to the dealer from whom the speaker was purchased. Installation for flying requires extensive technical knowledge and experience. The speaker may fall off if incorrectly installed, resulting in possible personal injury.

Flying Precautions

Be sure to follow the instructions below. Otherwise, the suspension wires or belts may be off or snap and the speaker may fall off, causing personal injury.

·Check to confirm that the suspension wires and belts are strong enough to withstand the speaker load.

·The connectors of the suspension wires and belts must be securely linked with those of the speaker.

·All parts and components (such as enclosures, metal pieces, and screws) must be free from any deformation, crack, and corrosion.

·Be sure to use screws supplied with the optional flying hardware when installing the speaker using such hardware.

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.

(HX-5B-WP and HX-5W-WP only)

When installing the unit in the snowy area, take appropriate measures to prevent snow from lying on the unit. If the snow lies on the unit, the unit may fall, causing personal injuries.

(HX-5B and HX-5W only)

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.

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 nuts and bolts that are appropriate for the ceiling's or 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.

Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by excessive vibration, potentially causing the unit to fall, which could result in 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

Avoid touching the unit's sharp metal edge to prevent injury.

To avoid electric shocks, be sure to switch off the unit's power when connecting speakers.

When the Unit is in Use

Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

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.

Do not stand or sit on, nor hang down from the unit as this may cause it to fall down or drop, resulting in personal injury and/or property damage.

Have the unit checked periodically by the shop from where it was purchased. Failure to do so may result in corrosion or damage to the unit or its mounting bracket that could cause the unit to fall, possibly causing personal injury.

2. GENERAL DESCRIPTION

The TOA HX-5 series is a 2-way compact speaker system that permits both constant directivity control over a wide frequency range and changes in directivity. It is ideal for reproducing clear sound in spaces with long reverberation times or high background noises. The HX-5B and HX-5W are designed for indoor use, while the HX-5B-WP and HX-5W-WP are for outdoor use.

3. FEATURES

Four speaker modules ensure high power and high quality.

The changeable orientation of each of the four speaker modules independently allows the directivity angle of the speaker system to be adjusted.

Built-in passive network ensures appropriate sound quality.

Ideal for both permanent and temporary installations, including both vertical and horizontal positioning.

Equipped with a convenient carrying handle.

Can be mounted directly on a wall or suspended by wire, chain or shackle with no need to use optional brackets.

Optional mounting brackets allow use in a wide variety of applications, including suspension, ceiling mounting, wall mounting, and speaker stand mounting. Mounting procedures are described in the instruction manuals enclosed with the mounting bracket or stand adapter.

4. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUITRY

The speaker system features internal input overload protection circuitry. If an extremely high input level is fed to the unit, the protection circuitry automatically cuts off the signal to the tweeters.

A drastic reduction in sound volume for the high frequency range indicates that the protection circuitry has been enabled.

In such cases, simply reduce the amplifier volume. The protection circuitry will automatically reset in approximately 10 seconds. After reset, try to maintain the volume at a level slightly lower than before.

Caution

This protection circuitry does not completely protect the unit against extremely high input power levels. Depending on the type or duration of excessive power input, the protection circuitry might not be enabled, resulting in damage to the speaker element. Also, if the excessive power input continues for a long period of time, the circuitry may not be capable of resetting to its original condition.

Use the system with care so that the speakers are not exposed to excessive power input.

5. INSTALLATION PRECAUTIONS FOR THE HX-5B-WP AND HX-5W-WP

Only the HX-5B-WP and HX-5W-WP are suitable for outdoor installation.

For outdoor installation, observe the following precautions.

All speaker modules must point downward from the horizontal. Failure to do so could adversely affect their intended weather-resistant capability, leading to malfunction.

Both the HX-5B-WP and the HX-5W-WP employ a splash-proof construction that allows them to be installed outdoors, but they should only be installed in locations where the ambient temperature is within the range of –15°C to +50°C. Exceeding the temperature range will cause the speaker to fail.
