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.

• 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.

• 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-1 is a cylinder-shaped, small flush-mount 2-way speaker featuring high sound quality.

3. FEATURES

• The H-1 Speaker System features, flush-mount speaker design with a rotatable cylinder-type enclosure. The speaker's smooth curved surface allows it to blend in with the interiors of most modern buildings.

• The speaker's small (8 x 5 cm) woofer featuring high input capacity ensures powerful sound reproduction.

• The one-inch balanced dome tweeter features ferro-fluid to ensure superb transient response characteristics for clear, high frequency sound output and high power-handling capabilities.

• The speaker's 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.

• The H-1 Speaker System is designed with an emphasis on installation ease and safety, as well as easier conduit wiring when an electrical box is installed.

• The cylinder-shaped speaker's mounting angle can be easily adjusted for up to ±45 degrees rotation.

• A built-in matching transformer permits the speaker to be used for both high- and low-impedance applications. For low-impedance applications, either the 4 Ω or 16 Ω terminal can be selected. Impedance can be easily changed from outside the unit.

• Detachable screw terminals facilitate connection. Dual positive and negative terminals also facilitate bridge connections.

• Both the speaker enclosure and Trim Piece are made of fire-resistant ABS (UL Standard 94: V-0 Grade).

• All external parts have been specially selected for ease of refinishing and repainting.
